cicorias / web3-solc-contract-compile-deploy.js

Created March 12, 2017 00:06 — forked from tomconte/web3-solc-contract-compile-deploy.js

Compiling and deploying an Ethereum Smart Contract, using solc and web3.

	const fs = require('fs');
	const solc = require('solc');
	const Web3 = require('web3');

	// Connect to local Ethereum node
	const web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));

	// Compile the source code
	const input = fs.readFileSync('Token.sol');
	const output = solc.compile(input.toString(), 1);

cicorias / compile-deploy-sign.js

Created March 12, 2017 00:06 — forked from tomconte/compile-deploy-sign.js

Shows how to compile and deploy a Smart Contract using client-side transaction signature, i.e. does not require the account to be unlocked in the Ethereum node.

	const fs = require('fs');
	const solc = require('solc');
	const Web3 = require('web3');
	const Tx = require('ethereumjs-tx')

	// Private key to use to sign the transactions
	// To decrypt your private key, use e.g. https://www.myetherwallet.com/#view-wallet-info
	// You will find your private key file in e.g. .ethereum/keystore or .parity/keys
	// In this example the key should correspond to the web3.eth.coinbase address
	var privateKey = new Buffer('088c110b6861b6c6c57461370d661301b29a7570d59cb83c6b4f19ec4b47f642', 'hex')

cicorias / truffle-config.js

Created March 12, 2017 17:06 — forked from tomconte/truffle-config.js

Example Truffle 3.0 configuration file to allow deploying contracts to an Azure "Bletchley" Ethereum consortium network. Based on the Truffle docs for Infura (http://truffleframework.com/tutorials/using-infura-custom-provider).

	var bip39 = require("bip39");
	var ethwallet = require('ethereumjs-wallet');
	var ProviderEngine = require("web3-provider-engine");
	var WalletSubprovider = require('web3-provider-engine/subproviders/wallet.js');
	var Web3Subprovider = require("web3-provider-engine/subproviders/web3.js");
	var Web3 = require("web3");

	// Insert raw hex private key here, e.g. using MyEtherWallet
	var wallet = ethwallet.fromPrivateKey(Buffer.from('324a58ceac32c9a5a465a57a87600c086df72aa4ae0c6beb062436a2b6c0a2a6', 'hex'));
