transfer

Parameters

Name	Type
_to	address
_value	uint256

Properties

Visibility public

Mutability transaction

Requirements

now must be greater than or equal to startTime

One or more of the following: - the result of calling safeSub with UNKNOWN ARGUMENT, _value must be greater than or equal to 50000000 - OR now must be greater than or equal to startTime + 1 years - OR owner must not be equal to the sender's address

Source Code

function transfer(address _to, uint256 _value) returns (bool success) {
  if (now < startTime) throw; //check if the crowdsale is already over
  if (
    msg.sender == owner &&
    now < startTime + 1 years &&
    safeSub(balanceOf[msg.sender], _value) < 50000000
  ) throw; //prevent the owner of spending his share of tokens within the first year
  balanceOf[msg.sender] = safeSub(balanceOf[msg.sender], _value); // Subtract from the sender
  balanceOf[_to] = safeAdd(balanceOf[_to], _value); // Add the same to the recipient
  Transfer(msg.sender, _to, _value); // Notify anyone listening that this transfer took place
  return true;
}
