返回值

名称 类型 描述
— uint8 The token's decimals as an unsigned 8-bit integer (e.g., 18).✨ AI
name() view → Wrapped Ether

Return the token's name as a human-readable string.✨ AI

返回值

名称 类型 描述
— string The token name string, e.g. "Wrapped Ether".✨ AI

写入函数

approve(guy: address, wad: uint256) nonpayable

Approve an address to spend up to a specified amount of tokens on your behalf.✨ AI

参数

名称 类型 描述
guy address Address that will be allowed to spend the caller's tokens.✨ AI
wad uint256 Amount of tokens allowed (in the token's smallest unit, e.g., wei).✨ AI

返回值

名称 类型 描述
— bool True if the approval succeeded.✨ AI
deposit() payable

Deposit ETH and receive the same amount of WETH tokens credited to your account.✨ AI

transfer(dst: address, wad: uint256) nonpayable

Transfer wad tokens from the caller to dst and return true on success.✨ AI

参数

名称 类型 描述
dst address Recipient address to receive the tokens.✨ AI
wad uint256 Amount of tokens to transfer, in wei units.✨ AI

返回值

名称 类型 描述
— bool True if the transfer succeeded.✨ AI
transferFrom(src: address, dst: address, wad: uint256) nonpayable

Transfer wad tokens from src to dst, using the caller's allowance when applicable.✨ AI

开发者： Reverts if src has insufficient balance. If caller != src, requires allowance >= wad; allowance is not reduced when equal to max uint256.✨ AI

参数

名称 类型 描述
src address Address to debit tokens from (source).✨ AI
dst address Address to credit tokens to (destination).✨ AI
wad uint256 Amount of tokens to transfer, in wei (smallest unit).✨ AI
