description: Using Pantheon with Truffle

Using Pantheon with Truffle

Developing for Pantheon using Truffle is the same as using Truffle to develop for the public Ethereum networks. Truffle supports Pantheon with the only difference being Pantheon does not implement private key management. To use Pantheon with Truffle, you must configure a Truffle wallet.

Install Truffle Wallet

To install the Truffle wallet:

npm install --save truffle-hdwallet-provider@web3-one

!!!note With Truffle 5, you must use a Web3 1.0 enabled wallet or the Truffle tasks hang.

Modify the Truffle Configuration File

Modify the truffle-config.js file in the project directory to add the wallet provider. Replace:

• <JSON-RPC-http-endpoint> with the JSON-RPC endpoint (IP address and port) of a Pantheon node
• <account-private-key> with the private key of an Ethereum account containing Ether

const PrivateKeyProvider = require("truffle-hdwallet-provider");
const privateKey = "<account-private-key>";
const privateKeyProvider = new PrivateKeyProvider(privateKey, "<JSON-RPC-http-endpoint>");

module.exports = {
  // See <http://truffleframework.com/docs/advanced/configuration>
  // for more about customizing your Truffle configuration!
  networks: {
    pantheonWallet: {
      provider: privateKeyProvider,
      network_id: "*"
    },
  }
};

Start Pantheon Node

Start a Pantheon node with JSON-RPC enabled on the endpoint specified in the Truffle configuration file.

Deploy Contract

To deploy a contract onto the Pantheon network:

truffle migrate --network pantheonWallet
