Events

  • Approval

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

    Emitted when the allowance of a `spender` for an `owner` is set by a call to `approve`. `value` is the new allowance.

    Parameters:
    owner - address
    spender - address
    value - uint256

  • Transfer

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

    Emitted when `value` tokens are moved from one account (`from`) to another (`to`). * Note that `value` may be zero.

    Parameters:
    from - address
    to - address
    value - uint256

Functions

  • allowance

    abstract 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:
    owner - address
    spender - address
    Returns:
    uint256

  • approve

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

    Sets `amount` as the allowance of `spender` over the caller's tokens. * Returns a boolean value indicating whether the operation succeeded. * > 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:
    spender - address
    amount - uint256
    Returns:
    bool

  • balanceOf

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

    Returns the amount of tokens owned by `account`.

    Parameters:
    account - address
    Returns:
    uint256

  • totalSupply

    abstract function totalSupply() external view returns (uint256)

    Returns the amount of tokens in existence.

    Returns:
    uint256

  • transfer

    abstract function transfer(address recipient, uint256 amount) external 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:
    recipient - address
    amount - uint256
    Returns:
    bool

  • transferFrom

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

    Moves `amount` tokens from `sender` to `recipient` using the allowance mechanism. `amount` is then deducted from the caller's allowance. * Returns a boolean value indicating whether the operation succeeded. * Emits a `Transfer` event.

    Parameters:
    sender - address
    recipient - address
    amount - uint256
    Returns:
    bool
