I'd like to be able to create a pool where users can deposit and withdraw ERC20 tokens. The caveat is that I don't have access to the assets in the pool but can only approve/reject the withdraw requests of the users.

  • User creates a withdraw of 100 USDT
  • I will approve the amount
  • contract deducts the 100 USDT from it's own address and transfers that 100 to user's address.

It's possible to do it securely with ETH but I can't seem to figure out how to do it with ERC20 tokens without giving myself complete access to the assets in the pool. Is it even possible?

the code for native transfer is here:

https://gist.github.com/zcaudate/366d8edfc748bd4ac8cfc40a98afc91e#file-room_native-sol-L271-L286

linking to the function that needs to be changed.
