Hello I am trying to create a crowdsale through zeppelin solidity but the main issue is it doesn't provide a way to link standard token with pre-allocated supply with the crowdsale.
pragma solidity ^0.4.13;
import '../node_modules/zeppelin-solidity/contracts/crowdsale/Crowdsale.sol';
import '../node_modules/zeppelin-solidity/contracts/token/StandardToken.sol';
contract BBTico is Crowdsale {
function BBTico(uint256 startTime, uint256 endTime, uint256 _rate, address _wallet)
Crowdsale(now, now + 5*60, 5, 0xB1A9B5564071A442909b17f8e9C7288b44aFC014 , 0xefcfbc96dc2adfe35d3fff6b1d9e985066d618ac)
{}
}
Crowdsale.sol
function Crowdsale(uint256 _startTime, uint256 _endTime, uint256 _rate, address _wallet) {
require(_startTime >= now);
require(_endTime >= _startTime);
require(_rate > 0);
require(_wallet != 0x0);
// Already Deployed Standard Token Address on Rinkeby Testnet
tokenReward = 0xEfCfbc96dc2aDfe35d3fFF6b1D9E985066D618aC;
startTime = _startTime;
endTime = _endTime;
rate = _rate;
wallet = _wallet;
}
// fallback function can be used to buy tokens
function () payable {
buyTokens(msg.sender);
}
function buyTokens(address beneficiary) public payable {
require(beneficiary != 0x0);
require(validPurchase());
uint256 weiAmount = msg.value;
uint256 accessTime = now;
// calculate token amount to be created
uint256 tokens = weiAmount.mul(rate);
// update state
weiRaised = weiRaised.add(weiAmount);
//The code doesn't compile with this function
tokenReward.transferFrom(0xB1A9B5564071A442909b17f8e9C7288b44aFC014,beneficiary, tokens);
}
