Examples for DevNet Local Setup

Introduction

Setting up DevNets for local development offers several benefits, including faster development and testing, customization of the network state, privacy and security, independence from public testnets, and integration with development tools.

Prerequisites

Before setting up a DevNet locally, make sure to:

1. Create a Tenderly account.
2. Set up a DevNet Template on Tenderly Dashboard.
3. Install the Tenderly CLI and login with your Tenderly credentials.

Hardhat Setup

To set up DevNet with Hardhat:

1. Install Hardhat.
2. Configure hardhat.config.js with your DevNet JSON-RPC URL and network name must be either tenderly or devnet.

Alternatively, use the spawn-rpc CLI command to automate the process.

Refer to the CI-project example for more details.

Foundry Setup

To set up DevNet with Foundry:

1. Make sure you have Rust and Foundry.
   1. Install Rust.
   2. Install Foundry.
2. Initialize a dummy Foundry project.

forge init

3. Deploy smart contracts using the forge create command.

forge create --rpc-url=$(tenderly devnet spawnRPC --template <YOUR_TEMPALATE_SLUG> --project <YOUR_PROJECT_SLUG>) ./src/Counter.sol:Counter --unlocked --from 0x0000000000000000000000000000000000000000

Truffle Setup

To set up DevNet with Truffle:

1. Install Truffle.

npm install -g truffle

2. Configure truffle-config.js with your DevNet JSON-RPC URL and Ethereum address.

module.exports = {
  networks: {
    devnet: {
      host: "YOUR_DEVNET_JSON_RPC_URL",
      network_id: "*",
      gas: 4700000,
      gasPrice: 20000000000,
      from: "YOUR_ETHEREUM_ADDRESS"
    }
  }
};

3. Run truffle migrate to deploy your contracts.

truffle migrate --network devnet

CI Integration

To integrate DevNet with your CI pipeline, use the spawn-rpc CLI command to spawn a DevNet instance and get the JSON-RPC URL.

tenderly devnet spawnRPC --template <YOUR_TEMPALATE_SLUG> --project <YOUR_PROJECT_SLUG>

Please refer to the CI-project example for more details.
