Project Setup

1. Configure Your Account

To deploy contracts to UOMI networks, you'll need to export your private key from MetaMask:

1. Open MetaMask

2. Select your account

3. Click the three dots menu

4. Go to "Account Details"

5. Select "Export Private Key"

6. Enter your password to confirm

You'll get a 64-character hex string like:

60ed0dd24087f00faea4e2b556c74ebfa2f0e705f8169733b01530ce4c619883

2. Store Your Private Key

Create private.json in your project root:

{
  "privateKey": "YOUR_PRIVATE_KEY_HERE"
}

⚠️ Security Warning Never commit your private key to version control. Add private.json to your .gitignore file.

3. Configure Networks

Modify your hardhat.config.js:

const { privateKey } = require("./private.json");

module.exports = {
  networks: {
    // Finney Testnet
    finney: {
      url: "https://finney.uomi.ai",
      chainId: XXX,
      accounts: [privateKey],
    },
  }
};

4. Deploy Your Contract

npx hardhat run --network finney scripts/deploy.js

Truffle Setup

Prerequisites

Install the HD Wallet Provider:

npm install @truffle/hdwallet-provider

Configuration

Modify your truffle-config.js:

const HDWalletProvider = require('@truffle/hdwallet-provider');
const { privateKey } = require('./private.json');

module.exports = {
  networks: {
    // Finney Testnet
    finney: {
      provider: () => new HDWalletProvider(
        privateKey,
        'https://finney.uomi.ai'
      ),
      network_id: XXX,
    },
  }
};

Deployment

Deploy to your chosen network:

truffle migrate --network finney

💡 Note If no network is specified, Truffle will use the default development network.
