DOMAIN_SEPARATOR() view

Returns

Name	Type	Description
—	bytes32

allowance(owner: address, spender: address) view

dev: See {IERC20-allowance}.

Parameters

Name	Type	Description
owner	address
spender	address

Returns

Name	Type	Description
—	uint256

balanceOf(account: address) view

dev: See {IERC20-balanceOf}.

Parameters

Name	Type	Description
account	address

Returns

Name	Type	Description
—	uint256

decimals() view

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

eip712Domain() view

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

Returns

Name	Type	Description
fields	bytes1
name	string
version	string
chainId	uint256
verifyingContract	address
salt	bytes32
extensions	uint256[]

name() view

dev: Returns the name of the token.

Returns

Name	Type	Description
—	string

nonces(owner: address) view

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

Returns

Name	Type	Description
—	uint256

symbol() view

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

Returns

Name	Type	Description
—	string

totalSupply() view

dev: See {IERC20-totalSupply}.

Returns

Name	Type	Description
—	uint256

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

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
value	uint256

Returns

Name	Type	Description
—	bool

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
_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

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
spender	address
value	uint256
deadline	uint256
v	uint8
r	bytes32
s	bytes32

transfer(to: address, value: uint256) nonpayable

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

Parameters

Name	Type	Description
to	address
value	uint256

Returns

Name	Type	Description
—	bool

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

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

Name	Type	Description
from	address
to	address
value	uint256

Returns

Name	Type	Description
—	bool
