Block #25,287,499 · just now
DOMAIN_SEPARATOR() view → 0x4e4fe710b9b512c332ff5e8b5d0413b1ace79b662b91fa3ea0ee4ec2c730d046

Return the EIP-712 domain separator used for signing typed data.✨ AI

Returns

Name Type Description
— bytes32 The EIP-712 domain separator (bytes32) for this contract, used in permit and typed-data signatures.✨ AI
allowance(owner: address, spender: address) view

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

dev: See {IERC20-allowance}.

Parameters

Name Type Description
owner address Address of the token owner whose allowance is being queried.✨ AI
spender address Address of the spender allowed to transfer tokens from the owner.✨ AI

Returns

Name Type Description
— uint256 The remaining allowance as a uint256 in the token's smallest unit (wei) that spender may transfer.✨ AI
balanceOf(account: address) view

Returns the aeWETH token balance for a given address.✨ AI

dev: See {IERC20-balanceOf}.

Parameters

Name Type Description
account address Address whose aeWETH balance will be returned.✨ AI

Returns

Name Type Description
— uint256 The account's aeWETH token balance as a uint256 in the token's smallest unit.✨ AI
decimals() view → 18

Returns 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 value {ERC20} uses, unless {_setupDecimals} is called. 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 The token's decimals as a uint8, indicating how many decimal places balances and amounts use.✨ AI

Returns the Layer 1 token contract address associated with this aeWETH token.✨ AI

Returns

Name Type Description

Return the Layer 2 gateway contract address used to bridge aeWETH.✨ AI

Returns

Name Type Description
— address The address of the L2 gateway contract that handles bridging for this token.✨ AI
name() view → dQw4w9WgXcQ

Returns the token's human-readable name.✨ AI

totalSupply() view → 0.03 RKA

Returns the total number of aeWETH tokens in existence.✨ AI

dev: See {IERC20-totalSupply}.

Returns

Name Type Description
— uint256 Total supply of aeWETH tokens as a uint256 in token base units.✨ AI

decreaseAllowance(spender: address, subtractedValue: uint256) nonpayable

Decrease the caller's token allowance for spender by subtractedValue and return true on success.✨ AI

dev: Atomically decreases the allowance granted to `spender` by the caller. This is an alternative to {approve} that can be used as a mitigation for problems described in {IERC20-approve}. Emits an {Approval} event indicating the updated allowance. Requirements: - `spender` cannot be the zero address. - `spender` must have allowance for the caller of at least `subtractedValue`.

Parameters

Name Type Description
spender address Address that will have its allowance decreased.✨ AI
subtractedValue uint256 Amount to subtract from the existing allowance.✨ AI

Returns

Name Type Description
— bool Boolean indicating whether the allowance was decreased successfully.✨ AI

Deposit native Ether to receive aeWETH tokens minted to your account.✨ AI

depositTo(account: address) payable

Deposit Ether and mint aeWETH tokens to the specified account.✨ AI

Parameters
