Summary

Adds MEV-boost as a sidecar service to enable validators to access MEV rewards when running full nodes in the Obol Stack.

Problem Solved

Fixes #34 - Validators running in the Obol Stack now have access to MEV rewards through integration with the block builder market.

Changes

🏗️ Infrastructure

  • MEV-boost Kubernetes Manifests: Created deployment, service, and network-specific configmaps in /manifests/mev-boost/
  • Automatic Deployment: MEV-boost deploys automatically when running with --mode full
  • Health Monitoring: Includes liveness/readiness probes

🔗 Network Support

  • Mainnet: 5 relays (Flashbots, Ultrasound, Bloxroute, Titan)
  • Sepolia: Flashbots Sepolia relay
  • Holesky: 3 relays (Flashbots, Ultrasound, Bloxroute)
  • Hoodi: No MEV support (skipped automatically)

⚙️ Consensus Client Integration

All consensus clients now support MEV-boost with appropriate flags:

  • Nimbus: --payload-builder=true --payload-builder-url=<mev-boost>
  • Lighthouse: --builder=<mev-boost>
  • Teku: --builder-endpoint=<mev-boost>
  • Prysm: --http-mev-relay=<mev-boost>
  • Lodestar: --builder=true --builder.urls=<mev-boost>

📚 Documentation

  • Comprehensive README with architecture, configuration, and troubleshooting guides
  • Network-specific relay information
  • Health check and monitoring instructions

Testing

To test MEV-boost integration:

  1. Deploy a full node: ./obolup --mode full --network mainnet
  2. Verify MEV-boost deployment: kubectl get pods -n l1 -l app=mev-boost
  3. Check MEV-boost status: kubectl logs -n l1 deployment/mev-boost
  4. Test endpoint:
    kubectl port-forward -n l1 svc/mev-boost 18550:18550
    curl http://localhost:18550/eth/v1/builder/status

Impact

  • ✅ Validators can now maximize staking rewards through MEV
  • ✅ Zero configuration required - works out of the box
  • ✅ Only deploys when needed (full nodes only)
  • ✅ Production-ready with proper monitoring and health checks

References

- Add MEV-boost Kubernetes deployment manifests
- Configure network-specific relay endpoints for mainnet, sepolia, and holesky
- Integrate MEV-boost with all consensus clients (Nimbus, Lighthouse, Teku, Prysm, Lodestar)
- Auto-deploy MEV-boost when running full nodes (--mode full)
- Add comprehensive documentation for MEV-boost setup

Fixes #34
- Update mainnet relays: Fixed Aestus and Agnostic relay addresses, replaced Ultrasound with Manifold
- Update sepolia relay: Corrected Flashbots Sepolia public key
- Update holesky relays: Use Aestus and Ultrasound staging relays
- Update documentation to reflect correct relay endpoints

Trying to get this turned on on my local machine and mev-boost is bootlooping, so going to commit some of my suggestions here and merge
