allowance(owner: address, spender: address)
view
Returns the remaining token allowance that owner has granted to spender.✨ AI
开发者： See {IERC20-allowance}.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| owner | address | Address that granted the allowance.✨ AI |
| spender | address | Address allowed to transfer tokens on behalf of the owner.✨ AI |
返回值
| 名称 | 类型 | 描述 |
|---|---|---|
| — | uint256 | Remaining allowance as a uint256: the number of tokens spender may still transfer from owner.✨ AI |
balanceOf(account: address)
view
Returns the token balance for the given account.✨ AI
开发者： See {IERC20-balanceOf}.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| account | address | Address whose token balance will be returned.✨ AI |
返回值
| 名称 | 类型 | 描述 |
|---|---|---|
| — | uint256 | The account's token balance as a uint256 in the token's smallest unit.✨ AI |
decimals()
view
Returns 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 value {ERC20} uses, unless this function is 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 | The token's decimals as a uint8 (the number of decimal places for token amounts).✨ AI |
name()
view
Returns the token's name as a human-readable string.✨ 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 string (human-readable).✨ 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 string (ERC-20 shorthand, e.g., "WMANTLE").✨ AI |
totalSupply()
view
Returns the total number of WMANTLE tokens in existence.✨ AI
开发者： See {IERC20-totalSupply}.
返回值
| 名称 | 类型 | 描述 |
|---|---|---|
| — | uint256 | Total token supply as a uint256 denominated in the token's smallest unit (base unit).✨ AI |
写入函数
approve(spender: address, amount: uint256)
nonpayable
Approve a spender to transfer up to a specified amount of your WMANTLE tokens.✨ AI
开发者： See {IERC20-approve}. Requirements: - `spender` cannot be the zero address.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| spender | address | Address approved to spend tokens on the caller's behalf.✨ AI |
| amount | 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 and the allowance was updated.✨ AI |
decreaseAllowance(spender: address, subtractedValue: uint256)
nonpayable
Decrease the caller's token allowance for a spender by a specified amount.✨ AI
开发者： 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`.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| spender | address | Address whose allowance will be decreased.✨ AI |
| subtractedValue | uint256 | Amount to subtract from the caller's allowance for the spender.✨ AI |
返回值
| 名称 | 类型 | 描述 |
|---|---|---|
| — | bool | True if the allowance was successfully decreased.✨ AI |
deposit()
payable
Deposits ETH and mints WMANTLE tokens to your account at the current exchange rate.✨ AI
开发者： mint tokens for sender based on amount of mantle sent.
increaseAllowance(spender: address, addedValue: uint256)
nonpayable
Increase the caller's ERC-20 allowance for a spender by the given amount.✨ AI
开发者： Atomically increases 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.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| spender | address | Address allowed to spend the caller's tokens.✨ AI |
| addedValue | uint256 | Amount to add to the existing allowance.✨ AI |
返回值
| 名称 | 类型 | 描述 |
|---|---|---|
| — | bool | True if the allowance was successfully increased.✨ AI |
transfer(recipient: address, amount: uint256)
nonpayable
Transfer tokens from the caller's account to the specified recipient address.✨ AI
开发者： See {IERC20-transfer}. Requirements: - `recipient` cannot be the zero address. - the caller must have a balance of at least `amount`.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| recipient | address | Destination address that will receive the transferred tokens.✨ AI |
| amount | uint256 | Number of tokens to transfer, expressed in the token's smallest indivisible unit.✨ AI |
返回值
| 名称 | 类型 | 描述 |
|---|---|---|
| — | bool | True if the transfer completed successfully.✨ AI |
transferFrom(sender: address, recipient: address, amount: uint256)
nonpayable
Transfers tokens from sender to recipient using the caller's allowance.✨ AI
开发者： See {IERC20-transferFrom}. Emits an {Approval} event indicating the updated allowance. This is not required by the EIP. See the note at the beginning of {ERC20}. Requirements: - `sender` and `recipient` cannot be the zero address. - `sender` must have a balance of at least `amount`. - the caller must have allowance for ``sender``'s tokens of at least `amount`.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| sender | address | Address whose balance will be decreased.✨ AI |
| recipient | address | Address whose balance will be increased.✨ AI |
| amount | 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.✨ AI |
withdraw(_amount: uint256)
nonpayable
Burn the specified amount of WMANTLE and release the corresponding underlying Mantle to the caller.✨ AI
开发者： withdraw mantle based on requested amount and user balance.
参数
| 名称 | 类型 | 描述 |
|---|---|---|
| _amount | uint256 | Amount of WMANTLE to withdraw, denominated in the token's smallest unit.✨ AI |
