Notes

Work in progress
At it's core, a set of tools to fill and show a postgres database
Multiple relays can serve a payload for the same slot (if the winning builder sent the best bid to multiple relays, and the proposer asks for a payload from all of them)

Overview

Uses PostgreSQL as data store
Configuration:
- Relays in /vars/relays.go
- Builder aliases in /vars/builder_aliases.go
- Version and common env vars in /vars/vars.go
Some environment variables are required, see .env.example
Saving and checking payloads is split into phases/commands:
- data-api-backfill -- queries the data API of all relays and puts that data into the database
- check-payload-value -- checks all new database entries for payment validity
- update-builder-stats -- create daily builder stats and save to database

Getting started

Run

You can either build relayscan from the repository, or use the Docker image:

# Build & run
make build
./relayscan help
./relayscan version

# Run with Docker
docker run flashbots/relayscan
docker run flashbots/relayscan /app/relayscan version

More example commands:

# Grab delivered payloads from relays data API, and fill up database
./relayscan core data-api-backfill                     #  for all slots since the merge
./relayscan core data-api-backfill --min-slot 9590900  #  since a given slot (good for dev/testing)

# Double-check new entries for valid payments (and other)
./relayscan core check-payload-value

# Update daily builder inclusion stats
./relayscan core update-builder-stats --start 2023-06-04 --end 2023-06-06  # update daily stats for 2023-06-04 and 2023-06-05
./relayscan core update-builder-stats --start 2023-06-04                   # update daily stats for 2023-06-04 until today
./relayscan core update-builder-stats --backfill                           # update daily stats since last entry, until today

# Start the website (--dev reloads the template on every page load, for easier iteration)
./relayscan service website --dev

Test & development

Start by filling the DB with relay data (delivered payloads), and checking it:

# Copy .env.example to .env.local, update ETH_NODE_URI and source it
source .env.local

# Start Postgres Docker container
make dev-postgres-start

# Query only a single relay, and for the shortest time possible
go run . core data-api-backfill --relay fb --min-slot -2000

# Now the DB has data, check it (and update in DB)
go run . core check-payload-value

# Can also check a single slot only:
go run . core check-payload-value --slot _N_

# Reset DB
dev-postgres-wipe

# See the Makefile for more commands
make help

For linting and testing:

# Install dependencies
go install mvdan.cc/gofumpt@latest
go install honnef.co/go/tools/cmd/staticcheck@v0.4.3
go install github.com/golangci/golangci-lint/cmd/golangci-lint@v1.51.2

# Lint and test
make lint
make test
make test-race

# Format the code
make fmt

Updating relayscan

Notes for updating relayscan:

Relay payloads are selected by inserted_at. When adding a new relay, you probably want to manually subtract a day from inserted_at so they don't show up all for today (UPDATE mainnet_data_api_payload_delivered SET inserted_at = inserted_at - INTERVAL '1 DAY' WHERE relay='newrelay.xyz';).
