If you are a Solana developer then

definitely you will like this particular

npm package which help you to test your

smart contract which you have written

for Solana blockchain doing all the

stimulation all the validation and

giving you separate environment which

you can use to do the testing and it's

super fast. So this is the one which we

use for c writing a custom contract and

testing all of that. This one is

absolutely amazing and it's very

lightweight. So you can come back here.

It's very easy to install and get start

with. So it's has the kairo model which

can simply do the installation and we'll

have this one. Now let's come back to

the documentation there we can able to

understand more about this particular

library that how we can utilize it. So

if you really want to work around this

particular repo you have to have a kairo

and you can simply run this particular

command to do the installation in your

project. Now let's come back to why we

use it. So it's called light svm. You

can simply call svm. That's what we call

in industry. So if you really want to

stimulate and take the traditional

approach, you can go with this one where

you can able to find the advanced

approach we have in the model which we

use like this is a client model. So you

can go with anyone like you have this

two options like some of the developers

they prefer to go with this particular

one but they also suggest this one as

well. So you can go with any model. Here

you will find the details about the

everything in synchronous way. So you

can simply process the transaction. If

you come back to the direct state

manipulation this is the model structure

we have. We can include if you want to

check the time under your control, we

have this one. But I really like this

one. It's very easy to integrate and we

can able to have the model. But you can

go with this one depending on the logic

which you want to build and perform the

transactional model. So there we have

this one. If you want to go with the

error model, that's all you can able to

follow and perform it. So there's tons

of things are there. I want you to come

back here and try to explore this

packet. This one is super powerful and

you will have tons of model which you

can use it. So if you come back to your

testing your program, you will find

quick start guide deploying program. You

can find executing instruction. If you

go back to the testing with SQL token,

you will have quick models. You can

click on this quick start. You will come

back to the page and there you will find

that how you can do the installation.

What are the ways to create the token,

initialize the model, how you can able

to run the testing, that's all is there.

If you want to take the token

operations, you can come back here and

you can simply copy this entire code and

you can simply integrate and you can

have the feature which you can use to

execute and test. So tons of the is

there. This one is also very super cool

because you know that when you want to

interact with the Solana you have to

deal with the like PD accounts. So this

one's also helps you a lot. You can use

it in multiple way like this one is

follow the AT accounts model which we

have where we assign the details about

the token and the reference which user

and the wallet is interacting. So tons

of things are there. I would highly

encourage you to have a look try to

understand the architecture because if

you want to build a custom testing your

contract and including different model

before you actually go back to the

mainet rather than testing in the dev

net you can simply go with this

particular architecture that's really

important. Now if I come back to the

examples there you will find we have

tons of examples right up here like soul

transfer how you can able to do that how

you can simply do it. There you will

find the complete code. If you go back

to the program deployment, here you will

have the entire snippet which you can

simply execute. If you want to go with

the PDA creation, there you will find

the model which can handle if you want

to handle the error. There you will find

the structure which you can simply

include it. Come back to the SPL token

operation cross program. So you can

simply have a look. Now if you come back

to the time based testing go back to the

anchor program example there you will

find because all the project we have

built if you come back to the blockchain

coder we have more than like 130 project

and we have built close to 40 project

related to Solana blossom. So if I type

Sana you will find all the project we

have all of these project for Solana

like NFD marketplace token creation with

different model fee swap model liquidity

that's all you will find. So I would

highly encourage you to come back here

check that how we have deployed the

contract. What is the airdrop model? We

have NFT marketplace, NFT creator, token

creator with multiple architecture. We

have the staking dab, we have the

referral model. So all of this project

we have. We have the ICO tab. If you go

further down, this one is the most

advanced and biggest project you will

find. We have the wallet model. So

that's all is there. So I would highly

encourage you to come back here. This

will saves a lot of your time. And if

you are not into core development and if

you don't want to give too much focus on

the rust then you can simply go with

this one. You can simply use this

snippet models and you can simply call

in your package and you will have the

entire feature for doing all the

testing. So that's the only thing for my

end. I hope you have understood this

project is absolutely phenomenal. It

will saves a lot of your time and it

will help you to give you the perfect

incorrect system which you can run to do

the testing and stimulate the entire

program. So that's the only thing for

mine. If you have any question, any

doubt, let me know in the comment

section. I'll definitely try to help in

that. Have a wonderful day.
