Is it possible to approve spending ERC20 token and execute a smart contract function that would transfer approved token (in Moralis Unity SDK)?
So I’m looking to implement following game flow:
- player authenticates in game (no problem)
- player press starts game
- call to game contract is initiated
- game contract transfer ERC20 token from user to itself - once game is paid for game starts
From what I’ve seen so far
- I could simply call ERC20 contract to send tokens
or - I can send native token to game contract
But is it possible to send tokens to game contract and transfer it from there with
IERC20(gameToken).transferFrom(msg.sender, address(this), gameFee);
so that I don’t end up with a two step process of transferring tocken , waiting for confirmation and only then starting the game…
