Using Truffle
This article will show you how to compile, deploy, and interact with smart contracts using Truffle on ICE testnode.
Truffle is a development environment focuses on the EVM compatible blockchains. Truffle is a one-stop shop for developing DApps. It facilitates with Compiling Contracts, Deploying Contracts, Injecting it into a Web App, Creating Front-End for DApps, and Testing.
npm install -g truffle
Create a metacoin project using following commands one by one
mkdir metacoin && cd metacoin
truffle unbox metacoin
npm install --save-dev @truffle/hdwallet-provider
After you've done this process, you'll have a project structure that includes the following items:
contracts/: Directory for Solidity contracts
migrations/: Directory for scriptable deployment files
test/: Directory for test files
truffle-config.js: Truffle config file
Modify truffle-config.js to add ICE testnet network. Also make sure to add your private key.
const HDWalletProvider = require('@truffle/hdwallet-provider');
const privateKeyTest = 'Your Private Key';
module.exports = {
networks: {
testnet: {
provider: () => {
if (!privateKeyTest.trim()) {
throw new Error(
'Please provide a private key with funds'
);
}
return new HDWalletProvider({
privateKeys: [privateKeyTest],
providerOrUrl: 'https://arctic-rpc.icenetwork.io:9933',
});
},
network_id: 552,
timeoutBlocks: 100 // To avoid quick timeouts
},
},
};
truffle compile
truffle deploy --network testnet
If everything goes right, you will be able to see output like this:
NOTE: If you get timeout errors then try adding following parameters to config file just below the network id & deploy with deploy command 2-3 times.
networkCheckTimeout: 9000000,
timeoutBlocks: 10000,
skipDryRun: true,
