GenericERC20

Generic ERC20 token

This contract simulates a generic ERC20 token that is mintable and burnable.

Methods

allowance

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

See {IERC20-allowance}.

Parameters

Returns

approve

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

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

Parameters

Returns

balanceOf

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

See {IERC20-balanceOf}.

Parameters

Returns

decimals

function decimals() external view returns (uint8)

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 {_setupDecimals} is called. 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

decreaseAllowance

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

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

Returns

increaseAllowance

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

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

Returns

mint

function mint(address recipient, uint256 amount) external nonpayable

Mints given amount of tokens to recipient

only owner can call this mint function

Parameters

name

function name() external view returns (string)

Returns the name of the token.

Returns

owner

function owner() external view returns (address)

Returns the address of the current owner.

Returns

renounceOwnership

function renounceOwnership() external nonpayable

Leaves the contract without owner. It will not be possible to call onlyOwner functions anymore. Can only be called by the current owner. NOTE: Renouncing ownership will leave the contract without an owner, thereby removing any functionality that is only available to the owner.

symbol

function symbol() external view returns (string)

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

Returns

totalSupply

function totalSupply() external view returns (uint256)

See {IERC20-totalSupply}.

Returns

transfer

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

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

Parameters

Returns

transferFrom

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

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

Returns

transferOwnership

function transferOwnership(address newOwner) external nonpayable

Transfers ownership of the contract to a new account (newOwner). Can only be called by the current owner.

Parameters

Events

Approval

event Approval(address indexed owner, address indexed spender, uint256 value)

Parameters

OwnershipTransferred

event OwnershipTransferred(address indexed previousOwner, address indexed newOwner)

Parameters

Transfer

event Transfer(address indexed from, address indexed to, uint256 value)
