allowance(owner: address, spender: address) view

Returns the remaining token allowance that the spender may use from the owner.✨ AI

開發者： 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.

參數

nonces(owner: address) view

Returns the current nonce for an address used to validate signed approvals and prevent replay attacks.✨ AI

開發者： Returns the current nonce for `owner`. This value must be included whenever a signature is generated for {permit}. Every successful call to {permit} increases ``owner``'s nonce by one. This prevents a signature from being used multiple times.

寫入函式

approve(spender: address, amount: uint256) nonpayable

Authorize spender to transfer up to amount of tokens from your account.✨ AI

開發者： 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.

參數

名稱 類型 描述
spender address Address authorized to spend tokens on behalf of the caller.✨ AI
amount uint256 Maximum token amount the spender is allowed to transfer.✨ AI

回傳值

decreaseAllowance(spender: address, subtractedValue: uint256) nonpayable

Decreases the caller's token allowance for a spender by a specified amount.✨ AI

開發者： Atomically decreases the allowance granted to `spender` by the caller. This is an alternative to {approve} that can be used as a mitigation for problems described in {IERC20-approve}. Emits an {Approval} event indicating the updated allowance. Requirements: - `spender` cannot be the zero address. - `spender` must have allowance for the caller of at least `subtractedValue`.

參數

名稱 類型 描述
spender address Address allowed to spend the caller's tokens.✨ AI
subtractedValue uint256 Amount to subtract from the spender's current allowance.✨ AI

回傳值

名稱 類型 描述

參數

名稱 類型 描述
account address Address that will receive the minted aeWETH tokens.✨ AI
increaseAllowance(spender: address, addedValue: uint256) nonpayable

Increase the caller's ERC-20 allowance for a spender by addedValue and emit an Approval event.✨ AI

開發者： Atomically increases the allowance granted to `spender` by the caller. This is an alternative to {approve} that can be used as a mitigation for problems described in {IERC20-approve}. Emits an {Approval} event indicating the updated allowance. Requirements: - `spender` cannot be the zero address.

參數

l1Address_ address Address of the corresponding L1 token contract (WETH) on Ethereum.✨ AI
permit(owner: address, spender: address, value: uint256, deadline: uint256, v: uint8, r: bytes32, s: bytes32) nonpayable

Allow a spender to spend the owner's tokens using an off-chain signature.✨ AI

開發者： Sets `value` as the allowance of `spender` over ``owner``'s tokens, given ``owner``'s signed approval. IMPORTANT: The same issues {IERC20-approve} has related to transaction ordering also apply here. Emits an {Approval} event. Requirements: - `spender` cannot be the zero address. - `deadline` must be a timestamp in the future. - `v`, `r` and `s` must be a valid `secp256k1` signature from `owner` over the EIP712-formatted function arguments. - the signature must use ``owner``'s current nonce (see {nonces}). For more information on the signature format, see the https://eips.ethereum.org/EIPS/eip-2612#specification[relevant EIP section].
