Drizzle & Kaleido Truffle Box

This box gives you a boilerplate to get up and running quickly with Drizzle & Truffle on a Kaleido chain.

Installation

First ensure you are in a new and empty directory.

  1. Run the unbox command with npx and skip to step 3. This will install all necessary dependencies.
npx truffle unbox kaleido-io/drizzle-kaleido-box
  1. Alternatively, you can install Truffle globally and then run the unbox command.
npm install -g truffle
truffle unbox kaleido-io/drizzle-kaleido-box
  1. Run the development console. This will instantiate a local chain for you to test that Truffle is working properly.
truffle develop
  1. Ensure that you're able to both compile, test, and finally migrate your contracts to your local chain.
compile
test
migrate
  1. If everything looks good, you can exit the Truffle console with .exit.

Connect to Kaleido

  1. In Kaleido, select the node you want to connect to, then choose + Connect Node.

  2. Select Native JSON/RPC

  3. Choose an application credential to use for this connection.

  4. Choose the Truffle Suite connection type.

  5. Copy the connection info from this panel into the respective variables inside of truffle-config.js. If you are using Quorum in this environment, ensure to uncomment the type: "quorum" property on your network object.

const appCred = 'yourappcred';
const connectionURL = 'nodeConnectionURL';

type: 'quorum' // Use this property for Quorum environments
  1. Migrate your contracts to your Kaleido chain!
truffle migrate

Connect MetaMask to your Kaleido Chain

  1. In the Networks switcher in MetaMask, choose Custom RPC.

  2. Find the New Network section, and click Advanced Options. Add the MetaMask RPC URL from the connect panel, and give your network a nickname.

Start Your React App

  1. Open the /app directory and start the development server.
cd app && npm run start

  1. The development server will open a browser at http://localhost:3000 by default.

  2. Attempt to change the Stored Value of SimpleStorage -- you should see the refresh icon until the transaction is confirmed, at which point the Stored Value of SimpleStorage should automatically update.
