I have been using yield Farming (YFValue) and I noticed when I accept the contract via MetaMask.
I set faming 500 USDT but in the contract the input was:
Function: approve(address _spender, uint256 _value) MethodID: 0x095ea7b3 : 000000000000000000000000c2d55ce14a8e04aef9b6bcfd105079b63c6a0ac8 : 000000000000000000000000000000000000314dc6448d932ae0a456589c0000
when I decode it via Etherscan it said:
_value uint256 999999999999999000000000000000000
My question is: does this mean that
_spender can take more the 500 USDT? If not can he repeatedly take 500 USDT every time and how to cancel it?
thank you in advance
