DOMAIN_SEPARATOR()
view
Returns the EIP-712 domain separator used to sign typed data.✨ AI
Returns
| Name | Type | Description |
|---|---|---|
| — | 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
dev: See {IERC20-allowance}.
Parameters
| Name | Type | Description |
|---|---|---|
| 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 |
Returns
| Name | Type | Description |
|---|---|---|
| — | 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
dev: See {IERC20-balanceOf}.
Parameters
| Name | Type | Description |
|---|---|---|
| account | address | Address to query the token balance for.✨ AI |
Returns
| Name | Type | Description |
|---|---|---|
| — | 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
dev: 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}.
Returns
| Name | Type | Description |
|---|---|---|
| — | 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
dev: See {EIP-5267}. _Available since v4.9._
Returns
| Name | Type | Description |
|---|---|---|
| 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()

Returns the ERC-20 token name used for display in wallets and user interfaces.✨ AI
dev: Returns the name of the token.
Returns
| Name | Type | Description |
|---|---|---|
| — | 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
dev: 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.
Parameters
| Name | Type | Description |
|---|---|---|
| owner | address | Address whose permit nonce is returned.✨ AI |
Returns
| Name | Type | Description |
|---|---|---|
| — | 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
dev: Returns the symbol of the token, usually a shorter version of the name.
Returns
| Name | Type | Description |
|---|---|---|
| — | string | The token symbol as a string (e.g., "WPPOM").✨ AI |
totalSupply()
view
Returns the total number of tokens in circulation.✨ AI
dev: See {IERC20-totalSupply}.
Returns
| Name | Type | Description |
|---|---|---|
| — | 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.
Returns
| Name | Type | Description |
|---|---|---|
| — | string | Semver contract version as a string. |
Write Functions
approve(spender: address, value: uint256)
nonpayable
Approve a spender to transfer up to value tokens from your account.✨ AI
dev: 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.
Parameters
| Name | Type | Description |
|---|---|---|
| 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 |
Returns
| Name | Type | Description |
|---|---|---|
| — | bool | True if the approval succeeded, otherwise false.✨ AI |
burn(_value: uint256)
nonpayable
Backwards compatibility function for burn. Calls withdraw
Parameters
| Name | Type | Description |
|---|---|---|
| _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.
Parameters
| Name | Type | Description |
|---|---|---|

| _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
dev: 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.
Parameters
| Name | Type | Description |
|---|---|---|
| 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
dev: See {IERC20-transfer}. Requirements: - `to` cannot be the zero address. - the caller must have a balance of at least `value`.
Parameters

| 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 |
Returns
| Name | Type | Description |
|---|---|---|
| — | 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
dev: 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`.
Parameters
