Returns the EIP-712 domain separator used to sign permits and other typed data.✨ AI

返回值

名称 类型 描述
— bytes32 The EIP-712 domain separator as a bytes32 value used to construct and verify typed data signatures.✨ AI
allowance(owner: address, spender: address) view

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

开发者： 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.

参数

名称 类型 描述
owner address Address that granted the allowance.✨ AI
spender address Address permitted to spend tokens on the owner's behalf.✨ AI

返回值

名称 类型 描述
— uint256 Remaining number of tokens (uint256) that the spender is allowed to transfer on behalf of the owner.✨ AI
balanceOf(account: address) view

Returns the token balance of a specified account.✨ AI

开发者： Returns the amount of tokens owned by `account`.

参数

名称 类型 描述
account address Address to query the token balance for.✨ AI

返回值

名称 类型 描述
— uint256 The account's token balance as a uint256 (in the token's smallest unit).✨ AI
decimals() view → 18

Returns the number of decimal places used by the token.✨ AI

开发者： Returns the decimals places of the token.

返回值

名称 类型 描述
— uint8 The number of decimal places used by the token as an unsigned 8-bit integer.✨ AI
l1Address() view → 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2

Get the Layer 1 contract address associated with this aeWETH token.✨ AI

— string The token's human-readable name (for example, "aeWETH").✨ AI
nonces(owner: address) view

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

开发者： 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.

参数

名称 类型 描述
owner address Address to query the nonce for.✨ AI

写入函数

approve(spender: address, amount: uint256) nonpayable

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

开发者： 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.

参数

名称 类型 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

返回值

名称 类型 描述
— bool True if the approval succeeded.✨ AI
bridgeBurn(account: address, amount: uint256) nonpayable

should decrease token supply by amount, and should (probably) only be callable by the L1 bridge.

参数

名称 类型 描述

amount uint256
bridgeMint(address, uint256) nonpayable

should increase token supply by amount, and should (probably) only be callable by the L1 bridge.

参数

名称 类型 描述
— address
— uint256
decreaseAllowance(spender: address, subtractedValue: uint256) nonpayable

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

开发者： 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`.

参数

名称 类型 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

返回值

名称 类型 描述
— bool True if the allowance was successfully decreased.✨ AI
deposit() payable

Deposit ETH and mint aeWETH tokens to your account.✨ AI

开发者： Accepts ETH via msg.value and mints aeWETH to msg.sender at the current exchange rate; may revert on failure.✨ AI
depositTo(account: address) payable

Accept ETH and mint aeWETH to the specified account.✨ AI

参数

名称 类型 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

开发者： 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.

参数

名称 类型 描述
spender address Address allowed to spend the caller's tokens.✨ AI
addedValue uint256 Amount to add to the current allowance, in the token's smallest unit.✨ AI

返回值

参数

名称 类型 描述
name_ string Token name to display in wallets and block explorers.✨ AI
symbol_ string Token symbol to display in wallets and block explorers.✨ AI
decimals_ uint8 Number of decimals used for token amounts in user interfaces.✨ AI
l2Gateway_ address Address of the Layer 2 gateway contract responsible for bridging.✨ AI
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

开发者： 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].

参数

名称 类型 描述
owner address Address of the token holder granting approval.✨ AI

transferFrom(from: address, to: address, amount: uint256) nonpayable

Move tokens from one address to another using the caller's approved allowance.✨ AI

开发者： Moves `amount` tokens from `from` to `to` using the allowance mechanism. `amount` is then deducted from the caller's allowance. Returns a boolean value indicating whether the operation succeeded. Emits a {Transfer} event.

参数
