balanceOf

Parameters

Name	Type
_owner	address

Properties

Visibility public

Mutability view

Source Code

function balanceOf(address _owner) public view returns (uint256 balance) {
  return balances[_owner];
}

transfer

Parameters

Name	Type
beneficiary	address
amount	uint256

Properties

Visibility public

Mutability transaction

Requirements

beneficiary must not be equal to UNKNOWN VALUE

amount must be less than or equal to balances for the sender's address

Source Code

function transfer(address beneficiary, uint256 amount) public returns (bool) {
  if (msg.sender != owner) {
    require(!paused);
  }
  require(beneficiary != address(0));
  require(amount <= balances[msg.sender]);

  // SafeMath.sub will throw if there is not enough balance.
  balances[msg.sender] = balances[msg.sender].sub(amount);
