Methods

allowance(address,address)

Solidity

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

Details

See {IERC20-allowance}.

Parameters

Name	Type	Description
owner	address	undefined
spender	address	undefined

Returns

Name	Type	Description
_0	uint256	undefined

approve(address,uint256)

Solidity

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

Details

See {IERC20-approve}. Requirements: - spender cannot be the zero address.

Parameters

Name	Type	Description
spender	address	undefined
amount	uint256	undefined

Returns

Name	Type	Description
_0	bool	undefined

balanceOf(address)

Solidity

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

Details

See {IERC20-balanceOf}.

Parameters

Name	Type	Description
account	address	undefined

Returns

Name	Type	Description
_0	uint256	undefined

decimals()

Solidity

function decimals() external view returns (uint8)

Details

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}.

Returns

Name	Type	Description
_0	uint8	undefined

decreaseAllowance(address,uint256)

Solidity

function decreaseAllowance(address spender, uint256 subtractedValue) external nonpayable returns (bool)

Details

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	undefined
subtractedValue	uint256	undefined

Returns

Name	Type	Description
_0	bool	undefined

increaseAllowance(address,uint256)

Solidity

function increaseAllowance(address spender, uint256 addedValue) external nonpayable returns (bool)

Details

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.

Parameters

Name	Type	Description
spender	address	undefined
addedValue	uint256	undefined

Returns

Name	Type	Description
_0	bool	undefined

name()

Solidity

function name() external view returns (string)

Details

Returns the name of the token.

Returns

Name	Type	Description
_0	string	undefined

symbol()

Solidity

function symbol() external view returns (string)

Details

Returns the symbol of the token, usually a shorter version of the name.

Returns

Name	Type	Description
_0	string	undefined

totalSupply()

Solidity

function totalSupply() external view returns (uint256)

Details

See {IERC20-totalSupply}.

Returns

Name	Type	Description
_0	uint256	undefined

transfer(address,uint256)

Solidity

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

Details

See {IERC20-transfer}. Requirements: - recipient cannot be the zero address. - the caller must have a balance of at least amount.

Parameters

Name	Type	Description
recipient	address	undefined
amount	uint256	undefined

Returns

Name	Type	Description
_0	bool	undefined

transferFrom(address,address,uint256)

Solidity

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

Details

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.

Parameters

Name	Type	Description
sender	address	undefined
recipient	address	undefined
amount	uint256	undefined

Returns

Name	Type	Description
_0	bool	undefined
