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.
