Hello, I'm working on a crowdsale. and just one query comes into my mind, like I've seen people provide their busd wallet address to deposit fund in presale, and once the fund gets deposited they transfer the token.
User A transfers into Owner BUSD account through a metamask or any wallet.
Owner transfers token directly to User account.
Now if I use the solidity I've a platform to emit an event which transfers the token but it needs to be emitted by some input.
What I'm looking after is Once the user transfers fund from any wallet the token gets transferred.
Is there any way we can get the address of users who are transferring directly through the wallet rather than coming to my react app?
