Run Ethereum Hive integration tests against a local Erigon build, including engine, RPC compatibility, standard EEST, BAL/Amsterdam EEST, and RLP suites. Use when setting up an ephemeral Hive environment, selecting or running Hive suites, interpreting Hive failures, or cleaning up Hive test resources.
Autonomous Goal-directed Iteration. Apply Karpathy's autoresearch principles to ANY task. Loops autonomously — modify, verify, keep/discard, repeat. Supports optional loop count via Claude Code's /loop command.
Integration test plan for erigondb.toml settings resolution across 3 runtime scenarios (legacy, fresh+downloader, fresh+no-downloader)
Use the 'erigon seg step-rebase' command to change the step size of an existing datadir. Use when the user wants to rebase segments or modify step sizes.
Run the full Erigon test suite locally using GOGC=80 make test-all. Use this before marking a PR ready for review. Equivalent to the "All tests" CI workflow.
Run Erigon tests with Go race detector to find data races and concurrency bugs. Use this for concurrency-sensitive changes (parallel executor, p2p, txpool). Takes 30-60 minutes.

When running multiple Erigon instances on the same machine, every listening port must be unique per instance. Erigon will fail at startup if any port is already in use, reporting bind: address already in use.
| CLI Flag | Default | Protocol | Description |
|---|---|---|---|
--private.api.addr | 127.0.0.1:9090 | TCP (gRPC) | Internal gRPC API for component communication (txpool, rpcdaemon, sentry, downloader) |
--http.port | 8545 | TCP | JSON-RPC HTTP server |
--authrpc.port | 8551 | TCP | Engine API (consensus layer auth RPC) |
--ws.port | 8546 | TCP | WebSocket RPC server |
--torrent.port | 42069 | TCP+UDP | BitTorrent protocol for snapshot downloads |
--port | 30303 | TCP+UDP | DevP2P network listening port (all eth versions multiplexed) |
--caplin.discovery.port | 4000 | UDP | Caplin consensus DISCV5 discovery |
--caplin.discovery.tcpport | 4001 | TCP | Caplin consensus DISCV5 TCP |
--sentinel.port | 7777 | TCP | Sentinel (consensus p2p service) |
--beacon.api.port | 5555 | TCP | Beacon Chain REST API |
--mcp.port | 8553 | TCP | MCP (Model Context Protocol) RPC server |
| CLI Flag | Default | Protocol | Description |
|---|---|---|---|
--pprof.port | 6060 | TCP | Go pprof profiling HTTP server (requires --pprof) |
--metrics.port | 6061 | TCP | Prometheus metrics HTTP server (requires --metrics) |
Instance 1 (using defaults):
./build/bin/erigon --datadir /path/to/datadir1
Instance 2 (all ports offset by +100):
./build/bin/erigon --datadir /path/to/datadir2 \
--private.api.addr=127.0.0.1:9190 \
--http.port=8645 \
--authrpc.port=8651 \
--ws.port=8646 \
--torrent.port=42169 \
--port=30403 \
--caplin.discovery.port=4100 \
--caplin.discovery.tcpport=4101 \
--sentinel.port=7877 \
--beacon.api.port=5655 \
--mcp.port=8653
--private.api.addr takes a full host:port value, not just a port number.--pprof or --metrics are enabled on both instances, their ports must also differ.
