The one thing you have to keep in mind
as a smart contract developer or a
auditor that you have to give focus to
the state variable which you include in
your smart contract. So when you are
changing the ownership for example you
have a function which allow the user to
transfer the NFT from one particular
address to another one before you make
the transfer you have to check that you
are passing the actual data of the NFT
and the ownership where you want to do
the transfer. So this is one is very
important concept which you have to
focus that you have to build your
function in at least three stage. One
the validation, second one is the
checking of the balance and third one is
transferring the ownership. So this is
the general architecture we follow. It
can be more complex depending on the
function, depending on the architecture
which you want to include.
