All of you, welcome back to yet another

project for Solana mastery. In this

project, you're going to build your

first ever advanced fullstack messaging

app on Solana blockchain with multimedia

file support where you can send audio,

video, images, text chat and you can

also transfer fund in your chat. So let

me give you a complete walk through of

all the feature we have included and how

our Solana chat application would work.

So when the user will come back to our

application, this is what exactly they

will see. The very first section we have

is our header section where you will

find the logo which you can customize.

You will have a button which you can

click and you can connect your wallet.

Then we have our hero section where we

are displaying the details about our

project. So this is going to be the logo

of our branding. Here you will find the

Solana chat. It's a decentralized chat

application which execute on the Solana

blockchain. We have our titles which you

can customize. And here we have another

button which user can click and they can

connect. Now if you come back to the

feature here we are providing all the

features which we are offering in our

decentralized chart application. So we

have the secure decentralization which

every single thing all the transaction

of the data would be stored in the smart

contract. So no one can able to

manipulate or change it. We have a

lightning fast system because we have

developed this project on the Solana

chain. We have multiple feature like

sending media file adding friend

transfer money. That's all we have. So

the transaction is going to be very

quickly within 1 second. You can see

this is the lowest but it can go more

low to the fee. We have a 100%

decentralization and we are following

this bite of data transfer which is

super fast. So this is the complete

overview of our application and our

welcome page. Now let's connect our

wallet and let's get into our dashboard.

So I'll simply click on my wallet and I

will pick I have all of these wallet. So

I'll go with Phantom. And once you will

connect your wallet you will come back

to the dashboard. From there you can

able to chat with your friends. If you

don't have friend you can simply connect

and make friend. So here we have on the

dashboard section you will find that we

have a stunning dashboard and futuristic

look. We have the very first section we

have is the header section and here you

will find on the right hand side our

profile. So I have the image you can

upload your profile if you don't want to

upload. It's going to display first text

of your name which you can see this. So

we have our name. We have our world

address. We have our profile. This is

the icon we have added and if you want

to disconnect you can simply click here

and you would be disconnected. Let's

connect one more time. Click on phantom

and I'm connected and here I am in my

dashboard. So that's the header section

we have. On the left hand side we have

our sidebar. There you will find the

list of all the friends. So the very

first section we have is the message and

from here you can able to click and you

can able to add friend. So you can able

to give their vault address, name and

you can click on add friend but they

have to be added and registered themsel

then you can able to add them or you can

come back to the browser section and

here you will find list of all the user

which is available and which you are not

friend with. So this is your wallet but

when the user will register and you are

not friend with you're going to simply

select and find them and you can select

and you can add them. So just click it

and it will be selected and you can call

the function and you would be added as a

friend. So let's close this one. Here we

have the filter system. So you can

simply filter your friend and if you

want to go to the specific chat to that

particular user you can simply select

and you will be open that that specific

chart and you can start communicating.

So if I go with coder there you will

find that all the messages I have

exchanged all the messages I have sent

that's all is there. So this is the

message I have sent and here you will

find that I have exchanged the media

file I have sent the money I have sent

the audio file I have sent the video I

have sent the image file I have this

text file. So all the things which you

will transfer is going to be reflecting

here and you will find the name of the

user, how many friend he has and these

are the icons we have. So this is the

chat interface. From there you can able

to communicate. If you come back here,

here you will find multiple media file

options. So if you want to send message,

if you want to send image, you can

simply click here and you can simply

upload the image file. If you want to

upload video, you can click here and you

can upload the video file. If you want

to send music, you can simply select

here and you can send your media file,

audio file. And if you want to transfer

fun, you can simply click here. You can

give the amount which you want to

transfer and it would be transferred to

this particular user. So let's close

this one. And here we have the option.

If you want to see your profile, you can

simply click here and you will find the

details about your profile. If you want

to update the image of your profile, you

can do it. But I would suggest you just

keep it one profile at a time. It would

be better. And you will find the number

of user you are friend with. Your

account is active and that's the details

you will find. You can simply copy that

and you have copied your address. Let's

close this one. Now you can see that I'm

connected with the admin account. I will

also have the access for the admin as

well. So you can simply click here and

it will open the admin panel and then

you can able to find all the stats like

how many user we have in our smart

contract. The deployer address. This is

the account which I have used for

deploying the smart contract. Our

contract is got initialized. So when you

will deploy the contract after that you

have to initialize then the user can

able to register themsel you can see

which network we have deployed it will

work absolutely fine on the mainet as

well you will find all of these details

we have the users and how many friends

each one of them have so this is the

detail section we have you can simply

click on refresh and it's going to

refresh the data so I'll simply close

this one and that's how our chat

interface would look like now let me

perform every single thing in practical

and show you all the transaction and

let's do that so what I will I'll simply

come back here, come back to this and

right now I haven't sent any message. So

I'll simply send the message. So I'll

simply come back here in my chat and I'm

going to copy the text right from here.

So let's copy it. So I'll come back here

and let's send the message. I'll simply

come here, paste the message and click

on this send and it's going to perform

the transactions. You can see it's going

to call our phantom wallet and we have

to simply login first. I haven't logged

in

and I have to simply click on confirm.

Simply ignore this one because it's a

devet. So we have this stimulation

function which we are not executing. So

just a warning simply click on confirm

and the transaction in the process. Once

the transaction will complete you will

see the message will popped up and here

the message is successfully sent to that

particular user. Send the audio file,

video file or image. It's very easy.

I'll send a let's say image. I'll come

back here and this is the one I have.

I'll simply select click on open and I

will have this beautiful preview where I

can see that what I'm sending. I can

give a caption but this one is optional

but let's give this caption and I click

on this send and here I'm uploading the

dot data to the IPFS then I'm calling

the smart contract so it's a really

powerful strategy let's click here and I

have to simply click on this confirm and

the transaction is happening once the

transaction will complete the file would

be sent and you will find the media file

would be reflecting here so it's taking

a little bit time because we are loading

the data you can come back here and you

can simply come here one more time and

you will find the media file is loading

so what we are doing we are not blocking

the execution of the function we are

loading it synchronously so you will

find that we have sent this one if you

want to send the like video you can do

that you can simply click on video and

you can select the video so I have this

video I'll click on this open and here I

can have the preview or I can simply

give the text I'll say hey

video and you can type any message click

on this send and here we are doing the

transaction so we are calling our smart

contract IPFS and making the transaction

ction. So just wait soon the process

will complete. I have to simply click on

confirm to execute the transaction. So

here we have successfully completed our

transaction and you will find the video

which is there in the chat. I can simply

click here and I can play the video

which I have uploaded. In the same way I

can simply upload and transfer the audio

file. I can click here pick the audio

file send here. I can give that I'll say

give this text and click on the send.

And here I'm uploading it.

We are making the call to our smart

contract. Let's click on this. Click on

this confirm. And we are simply sending

the audio file which is reflecting in

our fine with the icons with the image.

So every single thing is looking fine.

And this one is dynamic. It will

automatically get a reflect which when

you are communicating with the user. So

I can simply come back here and if I

want to transfer the fund I can do that

very easily. So if I come back to my

phantom wallet and you can see that I do

have a little bit fund which I can do

the transfer. So I have 04. So let's do

the transfer. So I'll simply come back

here. I'll click on this and I'm going

to transfer let's say 0.1

and click on this send and it's going to

transfer the fund to this chat and the

user will reflect receive. Let's click

on this confirm and just a moment soon

the transaction will complete and we

have done the transfer of the fund. So

it's really powerful. I hope you have

understood that what are the feature and

functionality we have included. I can

simply come back here and I can go back

to the different account which is the

account number let's say two and in

which I have sent and received all the

messages. So I'll simply give a quick

reload. So it's going to simply reload

the data and here you can see I got this

one. Now I can come back here and you

will find that all the messages which I

have received. So I'll simply come back

here and here you will find that this is

the messages I have received.

This is the messages and audio file and

the images I have sent. If I come back

to my account number one, you will find

that all the messages which I have

recently sent, that's all is going to be

visible in my chat. So I'll simply give

a reload because I have changed my

account. And here you will find that I'm

on account number one. I'll click on

this. Let's say the blockchain coder.

You will find all of this text, the

audio file, every single thing is

perfectly aligned. So first we have to

send the text, then the image, then the

video, audio and the money. That's all

is there. If I want to response back, I

can simply response in back in the text.

I can simply click here and I can simply

call the function. So let me help here.

Click on this confirm and here we have

it. So we have to send the message. If I

want to send the image back, I can do

that very easily. I can simply come back

here and I can simply go back to the

images, pick the image, click on open

and here I can give the caption or I can

simply click on the send and the message

would be sent absolutely perfectly. And

here we are sending the message. Click

on this continue and click on confirm.

And the transaction is completed. And we

have completed the entire transaction.

So that's how you can easily able to

simply send the messages, receive the

messages. If you want to add friend, you

can simply come back here. You can add

it manually or you can simply come back

here. Here you will find the list of all

the users. You can simply select them

and you can simply click on this add

friend.

Got it? So that's how every single thing

will be working. I hope you have

understood that what are the feature and

functionality we have included and this

is the automated system. The moment you

will bring it up your chat it will going

to bring it down and you will have all

of this details. Looks absolutely

perfect. Now if I want to update my

profile so I'll simply do that very

easily. I can do one thing. I can come

back here and I can come back here and I

will go to my account number two in

which I haven't uploaded my profile. So

right now you can see I'm connected with

the account number two. Let me reload

the page and you will find that I'm

connected with account number two but I

haven't uploaded my profile. So it's

very easy. I can simply check the

messages. I can read it and if I want to

update my profile I can simply click

here and I can click here and I have the

image which I can simply upload. So I

can simply take this one click on open

and it's going to upload the image and

we're going to have it. So here it's

calling our smart contract. I have to

click it. Click on this confirm and the

transaction in the process. So once the

transaction will complete the profile

would be updated and here you got it

profile it looks absolutely fine. So

your profile is updated in the same way

if you come back to a different account

and if you want to update the profile so

you can but don't try to do the profile

update frequently because you have to

pay money for it. I hope you can

understand. So you can see it's changed.

If I come back here and if I change it I

can do that very easily. So this one is

I have already updated. If I come back

here, click here and if I change this to

a different profile, I'm making a call.

It's going to make a update and I have

to simply confirm the transaction. Click

on confirm and it's going to simply

update my profile and the profile is

updated. So I hope you have understood

that what are the feature functionality

we have included. Every single thing is

working absolutely fine like a like a

bread and butter. So it's really

powerful. Every single things got

updated and we have all of the chat is

available which we can read and see

that. So I hope you can understand that

how powerful application it is. Every

single thing is controlled by the smart

contract. It's a full stack Solana

mastery project which will help you to

learn every single thing about the

Solana development and contract

development. So that's a really powerful

every single event is happening

perfectly. Now let me provide you all

the assets which you need to develop

this application and if you want to

foster your development you can take the

final source code as well. So you can

come back to the blockchain coder there

you will find that we have more than 100

plus project and we have built more than

30 to 40 project dedicated to the

Solana. So make sure to log in come back

to the source code section and here you

will find all the 100 plus project we

have developed. We have many project for

the Solana which you can also have a

look. So make sure to check all of that.

Now you have to come back here you can

search for it. You can click on this

recent project and here we have it. So

click on this. Make sure to check this

one play to earn. It's a really powerful

game where you can allow user to play

and when they will win they will get the

amount double and when they will lose

you will get the fund. So this is the

one we have. Click here and you will

come back here. I'm going to attach the

final source code setup video right up

here which is this one I'm recording.

You can click on the starter file and it

will take you to GitHub and here you can

able to understand all the architecture

which we have utilized and how every

single thing would be working. So make

sure to clone the repository, save it.

So when the complete project will come,

you can simply follow it straight away.

Now let me show you that how you can do

the final code setup. So make sure to

take it. When you will take it, you will

give your valuable contribution to my

team to bring more tutorial like this.

When you will download the final source

code, you will get the zip file. Make

sure to extract the zip file and you

will get this folder in which you will

have the complete source code of the

project including the smart contract you

have seen in the demo. So I would

suggest you to install a zip extractor

and extract this folder and this is the

one you have to open in your VS code. So

I'll click on my VS code and I'll go

back to open. I'll go back to desktop

because there I have my folder. I'll

simply select and click on open. Now let

me give you a complete walk through of

all the folder and file structure and

the architecture we have included in

this particular project. So let me make

a little bit zoom and you will find that

this is the complete architecture and

all the folder structure we have for our

application. So the very first folder we

have is the component in which you will

find all the component we have designed

for this full stack solana chat

application. So the very first one we

have is the at friend then you will find

all the code. So every single thing is

dynamic. I would suggest you to test as

it is once you understand completely

after that do all the experiment from

your end. So this is the ad friend this

is the admin dashboard. This is the chat

window, friend list, header, IPFS,

image, layout, loader, media preview,

message input, user profile, welcome.

Every single thing is dynamic. So this

is the welcome. If you want to change

the description and titles, you can do

the customization based on your

requirement. So let's close this one. So

that's all the component we have. The

next one we have is the context in which

you will find the chat context which

allow us to communicate with the smart

contract we have deployed on the Solana

chain and we have all the functionality.

So make sure to have a look. It's a

really powerful and that's all the

connection and all the function call we

are doing right up here. So just keep it

as it is. You don't need to make any

changes. Every single thing is dynamic.

Let's close this one. Come back here. Go

back to the contract and there you will

have the chat dab rush smart contract.

So this one is a really powerful smart

contract we have developed and it has

all the feature. This will help you to

master how you have to write the rust

smart contract. So this is a huge

contract we have coded more than 500

lines of code we have added and it's a

really powerful. It has all the feature

like building the relation, getting the

data, having the data, writing, updating

that's all we have. So you can check all

of this try to understand. So this is

the one which we're going to deploy and

when you will deploy you will have a

different address which you have to

provide. So I'll I'll show you all the

setup which you have to do. So let's

close this one. Now come back to the lib

in which you will find the AB of our

smart contract. So when you will deploy

the contract, we'll get the idle file

and that's what we going to replace

here. So let's close this one. Close

this one. come back to the pages and

it's going to be a single page

application. So we have this app.js

where we have done all the setup for the

context management and the wallet

integration. So you will find that we

are using all the wellestablished

packages for the industry. You will find

the network configuration. So I have

deployed the contract to the devet and

that's what I have added and here we

have the wallet which I'm offering and

that's all the setup we have. So just

keep it as it is. Close this one. Come

back to the index.js JS and here you

will find the complete homepage where we

are injecting all the component

dynamically for the user and for the

admin that's all is there so just keep

it as it is close this one close this

one come back to in which you will find

this particular the blockchain coder

logo but you can keep all the assets

which you want to have it that's all you

can keep into the public folder and you

can simply call it so let's close this

one come back here go back to the style

folder inside that we'll have the global

CSS and here we have written the entire

custom CSS for our entire application

with all the custom models So I just

suggest you to test as it is and if you

really want to change the branding color

you can do it but make sure you should

have a understanding about it. So this

is the global color which you can simply

play around with. Let's close this one.

Come back to the utils. There you will

find the utility function we have. So

this is the helper function which allow

us to short the address format check the

validation copy. That's all we have. So

you don't need to make any changes. You

can see all of this gradient component

which we have utilized. Now if you come

back to the pinata IPFS there you will

find that we are using this pinata

provider for deploying our document to

the pinata IPFS which is a distributed

network different endpoint. So this is a

huge code we have coded don't need to

make any changes just keep it as it is.

Close this one. I'll tell you what are

the things which you have to provide. So

all the things which you have to provide

in this environment variable. So if you

come back here this is very important.

You have to put your variable. So the

very first thing is program ID. So when

you will deploy the contract you will

get the program ID and that's what you

have to provide when you will deploy the

smart contract and the account which

you're going to use you have to provide

the void address of that particular

account which you will use for deploying

the contract we are testing on devet so

I have activated that here you have to

provide your pinata credential API key

secret key and JWP token and the rest

thing is going to be as it is so we're

going to get it each one of these

variable together just wait let's close

this one come back to the get ignore

keep it as it is we have the next config

files just keep it as it is we have the

packages and files And this one is the

most powerful packages we have used.

It's very stable and it will work

absolutely fine no matter when you are

developing this project. It will work

after 5 years, 10 years. It will work

absolutely fine as long as you maintain

this package for this particular video.

So let's close this one. Come back to

the post CSS. Every single thing is

good. Come back to the readme file and

then you will find all the details about

the project and what are the things you

need to have. So that's all is given.

But make sure to follow this video till

then you will understand every single

thing. Let's close this one. Come back

to the Telvin config. So this is the

custom configuration we have for our

Telwin setup. That's just keep it as it

is. Close this one. Now I hope you have

understood that what are the things and

folder file structure we have designed

for our application. Now the very first

thing we have to do is to deploy our

smart contract. This is the one we have

to deploy and perform all the

transaction and that's what we're going

to do it. So this is all we have it. So

what I will do I'm going to come back to

the browser and let's deploy the

contract for. So let's come back here

and let's open a new tab and type Sana

Playground ID. Make sure to search this

because right now there is a lot of fake

Solana Playground. If you connect with

them, they're going to steal your fund.

So always search on Google, come back

here and this is the official one. So

click here and you will come back to

your project and you will see that I

have already this project. So I'll

simply delete this one and I'm going to

start from fresh so you can be on the

same stage where I am. So right now you

can see that I have the empty project.

So the very first thing I have to do is

to create a project. I'll click here and

I'm going to call this chat dab and I'm

going to use anchor framework. It's a

really powerful. Click on create and

it's going to create the project for

you. We got the project. Now the very

first thing we have to do is to get our

contacts. Come back here. Select all.

Copy. Come back here. Select all.

Replace. Now you have to paste. So make

sure to save it. And once you will save,

you will have your contract up in right

up here in the project. Now I'm going to

simply connect with my wallet. So I'm

going to use my internal wallet which I

already have in my phantom wallet. So

this is the wallet which I'm going to

use for deploying the contract. So

that's the first thing. Let's close this

one. Now what I will do, I'm going to

simply compile my contract. So before

you compile, make sure to give a quick

reload after pasting the contract. And

you will find that every single thing is

well settled. We are using the same

vault address. And this is going to be

the admin of our contract. Now I'll come

back here and let's run the build

command. The moment you will run is

going to change the program ID and it

will give you the updated one. So let's

click on this build and this might takes

a little bit time. So just wait once it

will compile the contract. We'll get the

idle file and we are ready to deploy our

smart contract. So just wait. And you

can see that I'm getting this error in

the compilation because I already made a

lot of requests to the compiler. Don't

need to worry about it. Whenever you get

this error, make sure to reload the page

and save it one more time. Come back

here and let's give a one more try. So

it's going to compile your contract.

Once you will have the compiled

contract, you are ready to deploy it. So

just wait and finally our contract has

got compiled. So whenever you take a

little bit time, make sure your contract

is going to be successfully compiled.

And we got the detail built

successfully. Once you were done with

that, you will see this program ID got

updated. Now we are ready to deploy our

contract. This button is enabled. So

let's click on this deploy and it's

going to deploy our smart contract. So

just wait. Let's click on hit enter and

it's deploying our smart contract. So

just wait

and finally our contract is deployed.

I'll simply click here. You can come

back to the explorer and there you can

able to see all the details that what

are the execution we have developed and

this is our program ID which we need. So

you can able to see that what are the

internal contract what are the models

that's all we have. So this is the

successful contract deploy. Now you can

come back here and now I would suggest

you to copy this complete code and

that's what you have to paste here

because this time this editor will be

changed. So I'll simply select this

remove and paste. That's the first

thing. We got our updated contract. Now

close this one. Close this one. Come

back to the AI. I'll simply delete this

AI because we have our new AI. I'm going

to simply minimize this one. Come back

here and let's try to export our program

ID. So this is the one you can copy from

here till or you can simply copy from

here as well. So I'll simply copy and

that's what I'm going to provide in our

environment variable. So here I have to

provide paste here we got our program

ID. Now we have to get our AI. So let's

close this one. Come back here in the

file and here you will find your idle

file. So you have can simply import

export your API. So click here and you

have exported. Now you can come back

here. Go to this. Come back download and

there I have it. Simply drag and drop in

the lift file. I'll save it and it will

be formatted. So we got the most

important things done like we got our

API, we got our contract deploy, we got

the program ID. Now we're going to

simply provide the admin address which

is this one I have used. So I'll simply

click here and I'm going to click and

copy this. I have copied. Now I can come

back here and I'm going to simply paste

here.

We got it. So we got this three details.

Now we have to get our pinata epi and

secret key before we execute our project

because this will allow the user to

upload the media file. So let's come

back here open a new tab. Type pinata

cloud. It's a really powerful platform

and it's free to use it. So login and

verify your account. When you will

verify your account successfully you

will have the dash. I already have my

account. So I will simply login straight

away. I'll click on login and once you

will login successfully you will get

into your dashboard and you will find

all of this. I'm going to click here and

now I have to create a new API key. So

if I come back to the API keys, I have

already created one but to create a new

one, you can simply click here and you

can call this chat dab and make sure to

have to enable this one. In that way you

can able to have all the access and

click on this create and it's going to

create a brand new API key. So this is

the API key. Simply copy and that's what

you have to paste here.

That's what you have to paste here.

Again I will come back here. I'll copy

the secret key and that's what I have to

paste here. Now I have to get my JWT

copy and that's what I have to paste

here. Again I'm telling you you have to

use your own because after this project

I'm going to delete this one. It's free

to create your account free to get your

APK and secret key. So make sure to

create your own. Don't use my I'm going

to delete this and it will not work. So

we got all the important environment

variable which looks absolutely fine.

I'll close this one. Now we have to do

the installation of the packages. So if

you come back here we have to install

all of these packages and execute. So

what I will do I'll simply close this

one open up my terminal and right now

you can see I'm on the main directory

Solana chatdap in the main directory if

I show you my node version I have the

latest node version so there is no

problem it will work absolutely fine

with the latest node version so make

sure to check your node version if I

check my npm

version it's absolutely fine now what I

will do I simply going to install the

packages simply type npm I hit enter and

it's going to do the installation this

might takes a little bit time depending

on your internet speeds. So just wait

just let it be installed completely. You

can see the installation is started but

we getting this warning depreciated

depreciated. Simply ignore that it's not

that important. We are focusing on

stability. So just keep it as it is.

Don't need to make any changes in the

package version otherwise it's going to

fail. So don't run any one of these

command. Got it? Now I'm going to simply

clear up my terminal. Now we are done

with the installation and you will find

our node module is there. We have our

packages file. Now we are ready to start

our application. To start you can type

npm rundev and hit enter. Our

application will start on local host

3000. You can simply copy this one. You

can minimize from here or you can do it

just like this. But don't delete it. So

I'll minimize this. Now I'll come back

to my browser. I'll close all of this.

Open tab. Let's close this one because

we don't need this anymore. I'll come

back here. Paste this URL and hit enter.

And you will find that our application

is working absolutely fine. And this is

the account which is the admin and I'm

connected with. So I'll come back here.

You can see I'm on the account number

two which is not the admin. So I'll

simply come back here. Go back to

account number three. And this is the

account which I have used for deploying

the contract. And it has enough fun.

I'll simply reload the page and you will

find that I'm connected with the admin

account and here I'm getting an option

called initialize. And that's the first

thing you have to do. Once you deploy

your contract you have to initialize it.

So I'll simply click on this initialize

program and it's going to call the

function and it's going to start our

initialization. Click on this confirm

and it's going to perform the

transaction. Once the transaction will

complete you would have the dashboard

and now every single thing is ready.

User can come and they can create the

account. So first you as an ad have to

start and initialize the contract. So I

got the initialization. Now I'm ready to

create my account. So I'll simply click

here and I'm going to give my name. So

I'll say Dat Hussein. I'll click on this

create account and you have to create

your account transaction and once the

transaction will complete you will have

this dashboard and right now you can see

that there's no user if you click on

this add friend if you come back here

you are the only one there's no user so

you can have to register other other

user has to register into this

application then you can able to add

them into your friend but you can come

back to your profile and if you want to

update your image you can click here

select the image click on open and you

will find it's uploading and here we

have uploaded to the IPFS successfully

calling our smart contract and once you

call it you will find that our profile

is updated successfully.

So that's how you can update your

profile. Now what I will do I'll simply

come back here go back to the different

account and I will try to register one

more user from a different account. So

here you can see I haven't created

account from this that's why I'm getting

this one. I'll click on this create

account and I can select here. So I'll

say the chain coder and click on this

create account and again I have to

simply confirm the transaction and my

account would be created and I will have

the actions of the dashboard and now I

can able to make the friend. So you can

see I have created my account my profile

everything is looking good. Now if I

click on this add friend or you can do

it from here. If you come back to the

browser and you will find this is the

user is reflecting this is you and this

is the admin. So you can simply select

here you will see it will automatically

fill out all the details. Now click on

this add friend and it's going to make a

call and this user will be added as a

friend. So click on confirm and the

transaction is in the process. Here you

have added this user as a friend and you

will find in your friend list. So you

can simply select here and now you are

ready to send the message. So I'll say

copy this text and I can paste here and

click on this send and here you have to

perform two transactions. So let's click

on confirm.

and click on confirm because the reason

how smart contract work on the Solana

blockchain because this is a chat

application where you are performing the

chat between two user. So when you will

send the very first message after

becoming a friend you have to confirm

two transaction because in the first

transaction we are creating your pet

account which will build the relation

after that you can simply call one

function at one time to send the

messages. So if I try to call one more

time send this message it will have only

one transaction. Okay I hope you have

understood the logic of the smart

contract we have included. So this is

the very very straightforward logic we

have on the Solana chain. So before you

perform and register yourself you have

to perform the create a account into the

contract and perform the transaction. So

that's what we have. Now I can send the

media file. So I'll select here send

this media file and I can give the

details. Click on this send and it's

going to perform the transaction. And

the media file would be send

successfully. I'll click here, click on

this confirm and the transaction is

happening. And we have sent the media

file. In the same way, I can send the

video file. It's pretty easy. I can

select here, upload it. Or I can go with

this without text and send it. And it

will be sent to the user. And here it's

sending. Let's click on this confirm.

And the transaction is in the process.

And we have sent the video file. If you

want to send the audio file, it's pretty

easy. Select here. You can give your

description. Paste here. and it would be

sent successfully. Let's click on this

confirm and the transaction is completed

and you have sent the message and that's

all the messages which you will find. If

you come back here, if I go back to the

account number three which is the admin

which is receiving all the messages.

I'll give a reload and every single

thing would be updated. If you come back

here, you can see it's reflecting here.

Click here and you will find all the

messages he sent you. If you want to

reply it back then simply give your text

and you can simply send the message and

it's going to perform the transaction.

So let's click on this confirm and the

transaction is sent to the smart contact

and it's working fine. You can check

your profile one friend you have if you

are you are admin so I can simply click

here and you will find all the details

it's initialized this is the two user

all of things is looking great. So I

hope you have understood this is really

powerful every single feature is working

absolutely smoothly and this will help

you to understand that how you can build

complex structure of the smart contract

on decentralized ecosystem when it's

come to Solana and scalability. So I

hope you have understood that how you

have to perform all the transaction, how

you can become a friend, how you can add

a create your account, how you can send

the messages in multiple file. That's

all is there. That's all is there. So

that's the only thing I want to cover in

this video. I hope you have understood

the complete architecture. Soon the

complete project will come. So you can

follow it. But if you want to take the

final source code and faster your

development, you can come back to the

blockchain coder, get the final source

code and it will give you a valuable

contribution to my team. So this is the

really powerful project which you have

to include in portfolio to understand

the structure and understanding about

the smart contract in Rust programming

language and how you can deal with the

Solana blockchain and all the important

packages which you have to know as a

Solana blockchain developer. So that's

the only thing from my end in this

video. I hope you have understood every

single thing. If you have any question

any doubt let me in the comment section

or you can shoot an email to our

official email id. We'll provide you

more details around it. With that I'm

ending this video. Have a wonderful day.

Bye-bye.
