How to Set Up the MEV-Boost Relay for Ethereum Proposer-Builder Separation

The MEV-Boost Relay is essential for Ethereum’s proposer-builder separation (PBS), offering a more decentralized and transparent approach to block production. This guide will walk you through the setup process, troubleshooting tips, and the necessary components to run the relay smoothly.

Understanding the Relay Components: A Garden Analogy

Think of the MEV-Boost Relay as a vast garden where various plants (block producers and builders) need to thrive together. The components of the relay are like the specialized tools and structures that help the garden flourish:

• API: This serves as the watering system, providing essential nutrients (data) to the plants (block producers) to aid in their growth.
• Website: Acting as the garden’s path, it allows visitors (users) to navigate and access information about the garden’s bounty.
• Housekeeper: Similar to the gardener, this component maintains the plants by tending to them (updating validators and managing various tasks) to ensure they grow strong and healthy.

Setting Up the MEV-Boost Relay

To successfully set up the MEV-Boost Relay, follow these steps:

Step 1: Install Dependencies

• Ensure you have PostgreSQL, Redis, and optionally, Memcached installed.

Step 2: Start the Services

docker run -d -p 5432:5432 -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres -e POSTGRES_DB=postgres postgres
docker run -d -p 6379:6379 redis
docker run -d -p 11211:11211 memcached  # Optional

Step 3: Run the Housekeeper

go run . housekeeper --network sepolia --db postgres:postgres:postgres@localhost:5432/postgres?sslmode=disable

Step 4: Run the APIs and Website

go run . api --network sepolia --secret-key YOUR_SECRET_KEY --db postgres:postgres:postgres@localhost:5432/postgres?sslmode=disable
go run . website --network sepolia --db postgres:postgres:postgres@localhost:5432/postgres?sslmode=disable

Step 5: Query Status and Register Validators

curl localhost:9062/eth/v1/builder/status
curl -X POST -H "Content-Encoding: gzip" localhost:9062/eth/v1/builder/validators --data-binary @testdatavalreg2.json.gz

Troubleshooting

If you encounter issues while setting up the MEV-Boost Relay, here are some tips:

• Ensure all services (PostgreSQL, Redis) are running without errors.
• Check your network settings to ensure communication between components.
• If you face problems with block validation, review your beacon node configuration.
• Consult the Guide for running mev-boost-relay at scale for additional insights.
