读取函数

DOMAIN_SEPARATOR() view

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

返回值

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

Returns the remaining number of tokens that spender is allowed to transfer from owner.✨ AI

开发者： See {IERC20-allowance}.

参数

名称 类型 描述
owner address Address of the token holder who approved a spender.✨ AI
spender address Address authorized to transfer tokens on behalf of the owner.✨ AI

返回值

名称 类型 描述
— uint256 Remaining allowance expressed in the token's smallest unit (uint256).✨ AI
balanceOf(account: address) view

Returns the token balance of the specified account.✨ AI

开发者： See {IERC20-balanceOf}.

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 token balance of the account as an unsigned 256-bit integer.✨ AI
decimals() view

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

开发者： Returns the number of decimals used to get its user representation. For example, if `decimals` equals `2`, a balance of `505` tokens should be displayed to a user as `5.05` (`505 / 10 ** 2`). Tokens usually opt for a value of 18, imitating the relationship between Ether and Wei. This is the default value returned by this function, unless it's overridden. NOTE: This information is only used for _display_ purposes: it in no way affects any of the arithmetic of the contract, including {IERC20-balanceOf} and {IERC20-transfer}.

返回值

名称 类型 描述
— uint8 Number of decimal places (uint8) the token uses for display and calculations.✨ AI
eip712Domain() view

Return the EIP-712 domain components used for typed-data signing by this contract.✨ AI

开发者： See {EIP-5267}. _Available since v4.9._

返回值

名称 类型 描述
fields bytes1 bytes1: single-byte domain field used as a discriminator or reserved marker for the domain.✨ AI
name string name: human-readable name of the signing domain (typically the token or contract name).✨ AI
version string version: semantic version string that identifies the domain version for signatures.✨ AI
chainId uint256 chainId: numeric chain identifier (EIP-155) that the domain is bound to.✨ AI
verifyingContract address verifyingContract: address of the contract designated to verify EIP-712 signatures.✨ AI
salt bytes32 salt: 32-byte salt value included in the domain to provide additional uniqueness.✨ AI
extensions uint256[] extensions: array of numeric extension fields reserved for extra domain parameters.✨ AI
name() view

Returns the ERC-20 token name used for display in wallets and user interfaces.✨ AI

开发者： Returns the name of the token.

返回值

名称 类型 描述
— string The token name as a human-readable string for display (e.g., MyToken).✨ AI
nonces(owner: address) view

Returns the current permit nonce for an account.✨ 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 whose permit nonce is returned.✨ AI

返回值

名称 类型 描述
— uint256 The current nonce for owner used to validate off-chain permit signatures.✨ AI
symbol() view

Returns the token's short symbol used by wallets and user interfaces.✨ AI

开发者： Returns the symbol of the token, usually a shorter version of the name.

返回值

名称 类型 描述
— string The token symbol as a string (e.g., "WPPOM").✨ AI
totalSupply() view

Returns the total number of tokens in circulation.✨ AI

开发者： See {IERC20-totalSupply}.

返回值

名称 类型 描述
— uint256 Total number of tokens in existence as a uint256, expressed in the token's smallest unit (base units).✨ AI
version() view

Getter for the semantic version of the contract. This is not meant to be used onchain but instead meant to be used by offchain tooling.

返回值

名称 类型 描述
— string Semver contract version as a string.

写入函数

approve(spender: address, value: uint256) nonpayable

Approve a spender to transfer up to value tokens from your account.✨ AI

开发者： See {IERC20-approve}. NOTE: If `value` is the maximum `uint256`, the allowance is not updated on `transferFrom`. This is semantically equivalent to an infinite approval. Requirements: - `spender` cannot be the zero address.

参数

名称 类型 描述
spender address Address authorized to spend tokens on behalf of the caller.✨ AI
value uint256 Maximum number of tokens the spender is allowed to transfer.✨ AI

返回值

名称 类型 描述
— bool True if the approval succeeded, otherwise false.✨ AI
burn(_value: uint256) nonpayable

Backwards compatibility function for burn. Calls withdraw

参数

名称 类型 描述
_value uint256 Amount of tokens to burn / withdraw
deposit() payable

Deposit gas token for wrapped ERC20. Uses msg.value

donate() payable

Donate ETH for nothing in return

initialize(_nameIn: string, _symbolIn: string, _versionIn: string) nonpayable

Initializer.

参数

名称 类型 描述
_nameIn string ERC20 name
_symbolIn string ERC20 symbol
_versionIn string Version
permit(owner: address, spender: address, value: uint256, deadline: uint256, v: uint8, r: bytes32, s: bytes32) nonpayable

Permit allows a spender to be approved by the owner 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]. CAUTION: See Security Considerations above.

参数

名称 类型 描述
owner address Address of the token holder who signed the permit.✨ AI
spender address Address authorized to spend the owner's tokens.✨ AI
value uint256 Amount of tokens the spender is approved to spend.✨ AI
deadline uint256 Unix timestamp after which the permit is no longer valid.✨ AI
v uint8 Recovery byte v of the owner's signature.✨ AI
r bytes32 First 32 bytes of the owner's signature.✨ AI
s bytes32 Second 32 bytes of the owner's signature.✨ AI
transfer(to: address, value: uint256) nonpayable

Transfer tokens from the caller's account to the specified recipient and return success.✨ AI

开发者： See {IERC20-transfer}. Requirements: - `to` cannot be the zero address. - the caller must have a balance of at least `value`.

参数

名称 类型 描述
to address Recipient address that will receive the tokens.✨ AI
value uint256 Amount of tokens to transfer, expressed in the token's smallest unit.✨ AI

返回值

名称 类型 描述
— bool True if the transfer succeeded; false otherwise.✨ AI
transferFrom(from: address, to: address, value: uint256) nonpayable

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

开发者： See {IERC20-transferFrom}. Skips emitting an {Approval} event indicating an allowance update. This is not required by the ERC. See {xref-ERC20-_approve-address-address-uint256-bool-}[_approve]. 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 `value`. - the caller must have allowance for ``from``'s tokens of at least `value`.

参数

名称 类型 描述
from address Source address to debit tokens from.✨ AI
to address Destination address to credit tokens to.✨ AI
value uint256 Number of tokens to transfer.✨ AI

返回值

名称 类型 描述
— bool True if the token transfer operation succeeded.✨ AI
withdraw(wad: uint256) nonpayable

Withdraw ERC20 for gas token.

参数

名称 类型 描述
wad uint256 Amount of gas token to receive / wrapped ERC20 to burn.
