Voken-Sale Whitelist Registration trigger

// solidity

function transfer(address to, uint256 value) public whenNotPaused returns (bool) {
    if (_allowWhitelistRegistration && value == _whitelistRegistrationValue
        && inWhitelist(to) && !inWhitelist(msg.sender) && isNotContract(msg.sender)) {
        // Register whitelist for Voken-Sale
        _regWhitelist(msg.sender, to);
        return true;
    } else {
        // Normal Transfer
        _transfer(msg.sender, to, value);
        return true;
    }
}

Voken Public-Sale (Started at May-27) whitelist registration trigger conditions:

  • _allowWhitelistRegistration is true, when registration is allowed.
  • value = _whitelistRegistrationValue, that is 1,001 Vokens.
  • inWhitelist(to), receiver address is in whitelist.
  • !inWhitelist(msg.sender), sender address is not in whitelist.
  • isNotContract(msg.sender), sender address is not a contract, to avoid any “Coincidental accident” transfer from a contract, such as “any type of batch transfer”, “from an exchange” or any other contracts.

Transfers other than those under this special conditions are considered NORMAL TRANSFERS.
