My contract is as follows:
pragma solidity ^0.4.2;
contract Charity{
mapping (address => uint) public coinBalanceOf;
event CoinTransfer(address sender, address receiver, uint amount);
function charity(uint supply){
coinBalanceOf[msg.sender] = supply;
}
function sendCoin(address receiver, uint amount) returns (bool sufficient)
{
if (coinBalanceOf[msg.sender] < amount) return false;
coinBalanceOf[msg.sender] -= amount;
coinBalanceOf[receiver] += amount;
CoinTransfer(msg.sender, receiver, amount);
return true;
}
}
When I deploy using web3 1.0.0-beta with
import * as fs from 'fs' ;
import * as solc from 'solc' ;
import * as Web3 from 'web3' ;
var web3 = new Web3(new Web3.providers.WebsocketProvider('ws://localhost:8546'));
var contract_path : string = "../solidity/contracts/Charity.sol"
const input = fs.readFileSync(contract_path)
const output = solc.compile(input.toString(), 1);
var contract_name = ":" + pr.last(contract_path.split("/")).split(".")[0]
const bytecode = output.contracts[contract_name].bytecode
const abi_ = JSON.parse(output.contracts[contract_name].interface);
web3.eth.getAccounts().then(accounts => {
var coinbase = accounts[0];
var receiver = accounts[1];
// create contract
var myContract = new web3.eth.Contract(abi_, coinbase,
{
from : coinbase,
gasPrice: "2000000"
});
var deployedContract = myContract.deploy({
data: '0x' + bytecode,
}).send({
from: coinbase,
gas : 1500000 ,
gasPrice: '30000000000000'
}, (err, hash) => {
if (err) { console.log("error on deployment: ", err) }
console.log("Hash: ", hash)
})
myContract.methods.sendCoin(receiver, 7000000).send({
from: coinbase,
gas: 100000,
gasPrice: '10000000'
}, (err,val) => {
if (err) { console.log(err) }
else {
console.log("sent coin: ", val)
}
})
.then(console.log)
});
The contract deployed successfully but it’s not executing.
