Files for Integration

• base_deployed.json - Full deployment info with ABIs and addresses (use this for Bee node integration)
• deployments/base/ - Individual contract deployment artifacts
• helper-hardhat-config.ts - Network configuration reference

For Bee Node Developers

When integrating with Base:

1. Use swarmNetworkId: 2 to identify Base network
2. Contract addresses and ABIs are in base_deployed.json
3. Block timing is 2s (vs 5s on Gnosis) - round duration remains ~12.6 minutes
