proxiableUUID() view

Returns the UUID that identifies the storage slot used by UUPS proxies for this implementation.✨ AI

开发者： Implementation of the ERC1822 {proxiableUUID} function. This returns the storage slot used by the implementation. It is used to validate the implementation's compatibility when performing an upgrade. IMPORTANT: A proxy pointing at a proxiable contract should not be considered proxiable itself, because this risks bricking a proxy that upgrades to it, by delegating to itself until out of gas. Thus it is critical that this function revert if invoked through a proxy. This is guaranteed by the `notDelegated` modifier.

approve(spender: address, amount: uint256) nonpayable

Approve lets you authorize spender to transfer up to amount of your tokens.✨ AI

NOTE: Does not update the allowance if the current allowance is the maximum `uint256`. Requirements: - `from` and `to` cannot be the zero address. - `from` must have a balance of at least `amount`. - the caller must have allowance for ``from``'s tokens of at least `amount`.

参数

名称 类型 描述
