MEV-Boost Relay API Specs

Ethereum Relay API Specifications

The Relay API consists of two categories of APIs:

• Builder API for builders to submit blocks.
• Data API for anyone to query information about the relay.
  • Things like registrations, bids, and payloads.

For interacting with validators, a relay should follow the builder-specs.

Contributing

To clone the repository:

git submodule update --init --recursive

The API specification is checked for lint errors before merging pull requests.

To run the linter locally, install it with:

npm install -g @stoplight/spectral-cli@6.2.1

and then run it:

spectral lint relay-oapi.yaml

Render API Specification

To render spec in browser, you will simply need an HTTP server to load the index.html file in root of the repo.

For example:

python -m http.server 8080

The spec will render at http://localhost:8080.

Usage

Local changes will be observable if "dev" is selected in the "Select a definition" drop-down in the web UI.

It may be necessary to tick the "Disable Cache" box in their browser's developer tools to see changes after modifying the source.

Releasing

1. Create and push tag:
   • Ensure info.version in relay-oapi.yaml file is updated before tagging.
   • CI will create a GitHub release and upload bundled spec file.
2. Add release entrypoint in index.html

In SwaggerUIBundle configuration (inside index.html file), add another entry in urls field. Entry should be in following format (replace <tag> with real tag name from step 1.):

{url: "https://github.com/flashbots/relay-specs/releases/download/<tag>/relay-oapi.yaml", name: "<tag>"},
