寫入函式

approve(_spender: address, _value: uint256) nonpayable

Approve a spender to transfer up to a specified number of your tokens.✨ AI

開發者： Approve the passed address to spend the specified amount of tokens on behalf of msg.sender. Beware that changing an allowance with this method brings the risk that someone may use both the old and the new allowance by unfortunate transaction ordering. One possible solution to mitigate this race condition is to first reduce the spender's allowance to 0 and set the desired value afterwards: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729

參數

名稱 類型 描述
_spender address The address which will spend the funds.
_value uint256 The amount of tokens to be spent.

回傳值

名稱 類型 描述
— bool True if the approval was successful, otherwise false.✨ AI
reclaimToken(_token: address) nonpayable

Allows the contract owner to reclaim any ERC-20 tokens held by this contract.✨ AI

開發者： Reclaim all ERC20Basic compatible tokens

參數

名稱 類型 描述
_token address ERC20Basic The address of the token contract
transferFrom(_from: address, _to: address, _value: uint256) nonpayable

Transfer tokens from one address to another using an allowance and return true on success.✨ AI

開發者： Transfer tokens from one address to another

參數

名稱 類型 描述
_from address address The address which you want to send tokens from
_to address address The address which you want to transfer to
_value uint256 uint256 the amount of tokens to be transferred

回傳值

名稱 類型 描述
— bool true if the transfer was successful.✨ AI
unpause() nonpayable

Unpause the WBTC contract to re-enable transfers and other paused token functions.✨ AI

開發者： called by the owner to unpause, returns to normal state
mint(_to: address, _amount: uint256) nonpayable

Mint tokens to a recipient, increasing their balance and the total supply.✨ AI

開發者： Function to mint tokens

參數

名稱 類型 描述
_to address The address that will receive the minted tokens.
_amount uint256 The amount of tokens to mint.

回傳值

名稱 類型 描述
— bool A boolean that indicates if the operation was successful.
burn(value: uint256) nonpayable

開發者： Allows the pendingOwner address to finalize the transfer.
decreaseApproval(_spender: address, _subtractedValue: uint256) nonpayable

Decrease the allowance granted to _spender by _subtractedValue, not going below zero.✨ AI

開發者： Decrease the amount of tokens that an owner allowed to a spender. approve should be called when allowed[_spender] == 0. To decrement allowed value is better to use this function to avoid 2 calls (and wait until the first transaction is mined) From MonolithDAO Token.sol

參數

名稱 類型 描述
_spender address The address which will spend the funds.
_subtractedValue uint256 The amount of tokens to decrease the allowance by.

回傳值

開發者： Allows the current owner to relinquish control of the contract.
finishMinting() nonpayable

Permanently disable further token minting.✨ AI

開發者： Function to stop minting new tokens.

回傳值

名稱 類型 描述
— bool True if the operation was successful.
pause() nonpayable

Pauses all token transfers and state-changing functions in the WBTC contract.✨ AI

開發者： called by the owner to pause, triggers stopped state
transfer(_to: address, _value: uint256) nonpayable
