IERC 1363
Methods
allowance
Returns the remaining number of tokens that spender
will be allowed to spend on behalf of owner
through {transferFrom}. This is zero by default. This value changes when {approve} or {transferFrom} are called.
Parameters
Name | Type | Description |
---|---|---|
owner | address | undefined |
spender | address | undefined |
Returns
Name | Type | Description |
---|---|---|
_0 | uint256 | undefined |
approve
Sets amount
as the allowance of spender
over the caller's tokens. Returns a boolean value indicating whether the operation succeeded. IMPORTANT: Beware that changing an allowance with this method brings the risk that someone may use both the old and the new allowance by unfortunate transaction ordering. One possible solution to mitigate this race condition is to first reduce the spender's allowance to 0 and set the desired value afterwards: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729 Emits an {Approval} event.
