Using Hyperledger Besu with Truffle

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

Install Truffle Wallet

To install the Truffle wallet:

npm install --save [email protected]

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 Besu 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: {
    besuWallet: {
      provider: privateKeyProvider,
      network_id: "*"
    },
  }
};

Start Besu Node

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

Deploy Contract

To deploy a contract onto the Besu network:

truffle migrate --network besuWallet
