Methods

allowance

function allowance(address owner, address spender) external view returns (uint256)

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	undefined
spender	address	undefined

Returns

Name	Type	Description
_0	uint256	undefined

approve

function approve(address spender, uint256 amount) external nonpayable returns (bool)

Sets amount as the allowance of spender over the caller's tokens. Returns a boolean value indicating whether the operation succeeded. IMPORTANT: 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 Emits an {Approval} event.

Parameters

Name	Type	Description
spender	address	undefined
amount	uint256	undefined

Returns

balanceOf

function balanceOf(address account) external view returns (uint256)

Returns the amount of tokens owned by account.

Parameters

Name	Type	Description

totalSupply

function totalSupply() external view returns (uint256)

Returns the amount of tokens in existence.

Returns

transfer

function transfer(address recipient, uint256 amount) external nonpayable returns (bool)

Moves amount tokens from the caller's account to recipient. Returns a boolean value indicating whether the operation succeeded. Emits a {Transfer} event.

Parameters
