Write Functions

approve(_spender: address, _value: uint256) nonpayable

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

dev: 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

Parameters

Name	Type	Description
_spender	address	The address which will spend the funds.
_value	uint256	The amount of tokens to be spent.

Returns

Name	Type	Description
—	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

dev: Reclaim all ERC20Basic compatible tokens

Parameters

Name	Type	Description
_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

dev: Transfer tokens from one address to another

Parameters

Name	Type	Description
_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

Returns

Name	Type	Description
—	bool	true if the transfer was successful.✨ AI

unpause() nonpayable

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

dev: 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

dev: Function to mint tokens

Parameters

Name	Type	Description
_to	address	The address that will receive the minted tokens.
_amount	uint256	The amount of tokens to mint.

Returns

Name	Type	Description
—	bool	A boolean that indicates if the operation was successful.

burn(value: uint256) nonpayable

Burns the specified amount of tokens from the caller's balance and reduces the total supply.✨ AI

dev: Burns a specific amount of tokens.

Parameters

Name	Type	Description
value	uint256	Amount of tokens to burn, expressed in the token's smallest unit.✨ AI

claimOwnership() nonpayable

Complete the ownership transfer by assigning the pending owner as the current owner.✨ AI

dev: 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

dev: 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

Parameters

Name	Type	Description
_spender	address	The address which will spend the funds.
_subtractedValue	uint256	The amount of tokens to decrease the allowance by.

Returns

Name	Type	Description

dev: Allows the current owner to relinquish control of the contract.

finishMinting() nonpayable

Permanently disable further token minting.✨ AI

dev: Function to stop minting new tokens.

Returns

Name	Type	Description
—	bool	True if the operation was successful.

pause() nonpayable

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

dev: called by the owner to pause, triggers stopped state

transfer(_to: address, _value: uint256) nonpayable

Transfer tokens from the caller's account to the specified recipient address.✨ AI
