networks: {
  base: {
    url: "https://base-mainnet.g.alchemy.com/v2/" + process.env.ALCHEMY_API_KEY,
    accounts: [`0x${process.env.BASE_DEPLOY_PRIVATE_KEY}`]

Accessing Deployment Files

All deployment artifacts are stored in the deployments/ directory:

deployments/
├── base/                    # Production deployments
│   ├── Escrow.json
│   ├── Orchestrator.json
│   └── ...
├── base_sepolia/            # Testnet deployments
│   ├── Escrow.json
│   ├── Orchestrator.json
│   └── ...
└── base_staging/            # Staging deployments
    └── ...

Each JSON file contains:

• Contract address
• ABI (Application Binary Interface)
• Constructor arguments
• Deployment transaction hash
• Block number

Connecting to Contracts

Using Ethers.js

import { ethers } from 'ethers';
import EscrowABI from './deployments/base/Escrow.json';

const provider = new ethers.providers.JsonRpcProvider(
  'https://base-mainnet.g.alchemy.com/v2/YOUR_API_KEY'
);

const escrow = new ethers.Contract(
  '0x2f121CDDCA6d652f35e8B3E560f9760898888888',
  EscrowABI.abi,
  provider
);

Using Hardhat

import { ethers } from 'hardhat';

const escrow = await ethers.getContractAt(
  'Escrow',
  '0x2f121CDDCA6d652f35e8B3E560f9760898888888'
);

Network Selection

For Development

Use Base Sepolia testnet:

• Free testnet USDC available
• No real value at risk
• Faster confirmation times
• Test attestation infrastructure

For Staging

Use Base Staging environment:

• Production-like configuration
• Separate witness infrastructure
• Pre-production testing

For Production

Use Base Mainnet:

• Real USDC transactions
• Production attestation service
• Governed by multisig
• Full security measures active

Always test thoroughly on Base Sepolia before deploying to production. The testnet environment closely mirrors production but uses test tokens.

Production deployments on Base Mainnet are controlled by a multisig wallet (0x0bC26FF515411396DD588Abd6Ef6846E04470227). Direct contract modifications require multisig approval.
