DOMAIN_SEPARATOR() view

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

Returns

Name	Type	Description
—	bytes32	Domain separator (bytes32) used for EIP-712 typed-data signing.✨ AI

PERMIT_TYPEHASH() view

Returns the EIP-2612 permit typehash used for permit signature verification.✨ AI

Returns

Name	Type	Description

REPORTER() view

Returns the address currently assigned as the contract's reporter.✨ AI

Returns

Name	Type	Description
—	address	Address of the reporter role permitted to submit reports or updates (may be zero address if unset).✨ AI

allowance(owner: address, spender: address) view

Return the remaining number of tokens that spender is allowed to spend on behalf of owner.✨ AI

dev: 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.

Parameters

Name	Type	Description
owner	address	Address that owns the tokens.✨ AI
spender	address	Address permitted to spend the owner's tokens.✨ AI

Returns

Name	Type	Description
—	uint256	Unsigned integer representing the remaining allowance for spender to spend from owner.✨ AI

balanceOf(account: address) view

Return the current token balance for the specified account.✨ AI

dev: Returns the amount of tokens owned by `account`.

Parameters

Get the total number of shares. Needs to be overridden by the child contract.

Returns

decimals() view

Returns the number of decimal places the token uses.✨ 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}.

name	string	name — domain name string used in the EIP-712 domain (typically the token or contract name).✨ AI
version	string	version — domain version string used in the EIP-712 domain.✨ AI
chainId	uint256	chainId — chain identifier (uint256) the domain is bound to for replay protection.✨ AI
verifyingContract	address	verifyingContract — address of the contract acting as the EIP-712 domain verifier.✨ AI
