Smart Router

The reliability and security layer for blockchain RPC. Smart Router monitors and orchestrates multiple RPC upstreams in real-time, providing failover, cross-validation, caching, observability & more — across EVM and non-EVM networks.

What is Smart Router

RPC proxies have been built in-house thousands of times — along with the failover, caching, and monitoring that surround them. Smart Router is that layer as a standard, actively maintained component: a single endpoint in front of all your RPC upstreams. Instead of building and maintaining your own, you get:

Automatic failover — retries a bad upstream on another, hedges slow ones in parallel, skips out-of-sync upstreams, and trips a circuit breaker when the pool is exhausted.
Data cross-validation — fans a read out to several upstreams and returns only once a quorum agrees, stopping conflicting or malicious responses before they reach you.
Block-aware caching — serves repeat reads without hitting an upstream and without serving stale data; shareable across replicas.
Transaction broadcasting — sends writes (eth_sendRawTransaction and equivalents) to all eligible upstreams in parallel to raise success rate and speed.
Multi-chain, multi-protocol — JSON-RPC, REST, gRPC, Tendermint RPC, and WebSocket across EVM chains, Solana, UTXO chains, Cosmos chains, and more; chains are defined by JSON specs.
Built-in observability — Prometheus metrics, OpenTelemetry traces, structured logs, and a typed error taxonomy, with a companion Smart Router Dashboard.

Quick Start

The fastest way to start: install the binary, point it at a YAML config, run.

Prerequisites

Go 1.26+

Build & run

make install
smartrouter config/smartrouter_examples/smartrouter_eth.yml --use-static-spec specs/

After running, you get:

An RPC endpoint per chain interface (ports from the YAML config; conventional default :3360).
Prometheus metrics on :7779 — see docs/METRICS.md for the full reference.
A health endpoint at /lava/health.
Provider rotation, RPC-aware retry, response caching, and metrics — all driven by the YAML config.

Config wizard

Don't want to hand-write the YAML? A Charm-based TUI builds a smartrouter config and runs the local docker compose stack — from "which chains?" to a running, health-verified router.

make wizard          # from the repo root (builds the router, then launches)
# or
cd tools/wizard && go run . --repo /path/to/smart-router

See tools/wizard/README.md for the full walkthrough.

Health check (`smartrouter health`)

A spec-driven, one-shot diagnostic that crafts and sends the relays each spec defines to every configured upstream node URL, then prints a single JSON report to stdout. It's chain-agnostic — it relies entirely on the loaded specs, so any chain or interface with a spec works out of the box with no per-chain code. For each node URL it runs the standard latest-block call plus every verification the spec declares for that node's addons/extensions (archive / debug / trace and, when the spec supports subscriptions, a websocket check on wss:// URLs).

# Probe every node-url under direct-rpc in a config file
smartrouter health config/smartrouter_examples/smartrouter_eth.yml --use-static-spec specs/

# Or probe an ad-hoc endpoint inline (address chain-id api-interface)
smartrouter health https://ethereum-rpc.publicnode.com ETH1 jsonrpc --use-static-spec specs/

The report is the only thing on stdout (all logs go to stderr), so it pipes cleanly into jq or a downstream verifier:

smartrouter health smartrouter_eth.yml --use-static-spec specs/ 2>/dev/null | jq '.results[] | {name, url, ok}'

The document is a uniform envelope — consumers always JSON.parse stdout and read .ok / .error / .results; they never inspect the exit code, which is 0 for any completed run (endpoint failures are reported as data, not as a non-zero exit). Only a fatal setup error (bad config, missing --use-static-spec) exits non-zero, and even then a JSON envelope with a populated error is printed first.

{
  "ok": false,
  "error": null,
  "results": [
    {
      "name": "eth-publicnode",
      "chainId": "ETH1",
      "apiInterface": "jsonrpc",
      "url": "wss://ethereum-rpc.publicnode.com",
      "transport": "ws",
      "addons": ["debug"],
      "extensions": ["archive"],
      "specValid": true,
      "latestBlock": 25374584,
      "ok": false,
      "verifications": [
        { "name": "chain-id", "addon": "",      "extension": "",        "ok": true },
        { "name": "archive",  "addon": "",      "extension": "archive", "ok": false, "error": "block not found" }
      ]
    }
  ]
}

An upstream with multiple node URLs (e.g. an https:// and a wss:// endpoint) yields one row per URL, distinguished by url/transport. An endpoint's ok is true only when the spec loaded (specValid) and every verification passed. Top-level ok is the AND of all rows.

Flag	Default	Purpose
`--use-static-spec`	(required)	Spec source(s) — file, directory, or remote URL (same paths as the main command)
`--include-backup`	`false`	Also probe upstreams under `backup-direct-rpc`
`--timeout`	`30s`	Per-upstream timeout, and the basis for the global wall-clock cap (upstreams probe concurrently; the run never exceeds `timeout + 5s`). A slow/blocked node aborts instead of hanging
`--skip-websocket-verification`	`false`	Exclude `ws://`/`wss://` endpoints and the spec's websocket verification (see note)
`--log-level`	`info`	Log verbosity (written to stderr)

Websocket is verified by default. For any chain whose spec supports subscriptions, the command probes the configured ws:///wss:// endpoints and runs the spec's websocket verification — so the health check exercises the full surface a supported chain exposes. A blocked or slow ws node can't stall the run: each upstream is bounded by --timeout, upstreams probe concurrently, and a global wall-clock cap (timeout + 5s) guarantees the command returns even if a connector wedges (an upstream that doesn't finish in time is reported as a timed-out row). Pass --skip-websocket-verification to exclude ws endpoints — useful for a fast HTTP-only sanity check; each excluded URL is then reported as a row marked "websocket verification skipped".

Run with Docker Compose

No host Go toolchain needed — build and run the binary (plus an optional cache) in Docker:

docker compose -f docker/docker-compose.yml up --build

A single parameterized stack serves every example config (SR_CONFIG=…), with the cache added by layering an overlay compose file. See docs/LOCAL-COMPOSE.md for the full guide — config switching, the cache overlay, multi-chain examples, and logging/metrics.

With the monitoring dashboard

The Smart Router Dashboard is a Prometheus-driven observability UI for the router (chain/upstream health, RPS, latency, errors, a live request console, and more). It lives in its own repo and ships a self-contained stack — router + Prometheus + dashboard — from one command, so there's nothing to run from here.

git clone https://github.com/Magma-Devs/smart-router-dashboard
cd smart-router-dashboard
make up          # router + Prometheus + api (:8000) + web (:3000) + logs (Grafana :3001)

See the dashboard README for configuration (auth, the values file, logs profile, pointing it at an existing router on :7779, etc.).

AI / Codex setup

See AGENTS.md.

Configuration

Upstream endpoints are configured in a YAML file. See config/smartrouter_examples/smartrouter_cosmos.yml for an example targeting Cosmos Hub with two distinct public sources per interface (REST + gRPC + Tendermint RPC), and config/smartrouter_examples/smartrouter_multichain_cross_validation.yml for a multi-chain fleet with an active cross-validation policy block. Every bundled example points at public RPC vendors (PublicNode and each chain's official/community endpoints) — no API key required.

Setup scripts are available in scripts/pre_setups/:

# Lava blockchain (REST + gRPC + Tendermint RPC)
./scripts/pre_setups/init_smartrouter_lava.sh

# Ethereum (JSON-RPC)
./scripts/pre_setups/init_smartrouter_eth.sh

            Statically-configured upstream RPC providers
              (Lava chain providers, PublicNode, Infura,
               self-hosted nodes, ...)

The hot path for a single request:

Listen — a per-interface listener (JSON-RPC, REST, gRPC, or Tendermint RPC) accepts the request and parses it into a normalised internal shape.
Cache lookup — for cacheable methods (historical block data, immutable receipts, etc.), the cache layer (ecosystem/cache) checks for a recent response. Hits return immediately.
Upstream selection — on cache miss, the upstream optimiser (protocol/provideroptimizer) picks an upstream from the configured pool using QoS-weighted scoring. Healthy/fast upstreams are preferred; flaky ones get backed off automatically.
Relay + failover — the request is sent to the chosen upstream. On failure (timeout, malformed response, certain status codes), the retry state machine picks an alternate upstream and retries within a configurable budget.
Response — returned to the client with metadata headers (Smart-Router-Version, Lava-Provider-Address, retry counts, etc.) annotating which upstream served the response. Prometheus metrics are emitted in parallel.

Cross-validation (optional). For read methods that warrant extra assurance, the relay step can instead fan out to several upstreams in parallel and only return an answer once a quorum agree on an identical response — optionally requiring the quorum to span multiple distinct upstream groups (or each group to reach its own quorum). It defends against a single upstream returning a wrong-but-well-formed answer, and surfaces dissent via response headers and a bounded mismatch metric. See docs/CROSS-VALIDATION.md for an operator setup guide with runnable example configs, or protocol/rpcsmartrouter/README.md for the full knob/header reference.

What it's not

Not a load balancer. Generic L4/L7 balancers don't speak RPC. They can't distinguish a transient timeout (retry against another upstream), "block not yet produced" (retrying anywhere won't help), and a malformed JSON-RPC envelope (return the error, don't retry). They can't cache by method+params, and they can't back off an upstream that's silently serving stale block data while still returning 200 OK. Smart Router does all of these.
Not a node. Smart Router doesn't sync chain state or hold a block tree. It forwards requests to upstreams (managed services or self-hosted nodes) configured statically via YAML and scores them on response quality. If every configured upstream goes dark, the router has nothing to fall back on — pair it with an upstream set wide enough to survive operator-level outages.

Supported Chains

Smart Router ships with specs for 120+ chain networks — EVM L1s and L2s, Cosmos SDK chains, non-EVM L1s (Solana, Sui, TON, Starknet, NEAR, Aptos, Move, …), Bitcoin-family chains, Ethereum Beacon, and more. The Index column is the value to reference in your YAML config or --chain-id.

Development

Build targets

make build          # Build smartrouter binary to build/
make install        # Install smartrouter to $GOPATH/bin
make snapshot       # Reproduce a release locally in dist/ (binaries + multi-arch Docker image)
make setup          # One-time: ensure docker buildx is configured (auto-run by `make snapshot`)
make test           # Run all tests

make lint           # Run go vet
make tidy           # Run go mod tidy
make clean          # Remove build artifacts

make build and make install inject the same version metadata via ldflags that CI uses (git describe for Version, git rev-parse HEAD for Commit), so a local build on a given commit is byte-identical to CI's for that commit (under the same Go toolchain).

Debug endpoints

When started with --debug-address <addr> (and devMode.enabled=true), the router serves a small reset HTTP API for integration tests. It is off by default and absent from production builds.

The reset tests rely on is POST /debug/reset-all, which drains the router's internal state stores (optimizer scores, Ristretto, seen-block caches, retry bans, session-manager state) and — so a single call returns the router to a serving state after an all-providers-down stress burst — also re-enables endpoint health and cold-rebuilds pairing.

Why that matters: an endpoint that hits MaxConsecutiveConnectionAttempts consecutive connection failures is disabled (Endpoint.Enabled=false), and the only paths back are a successful relay or the ~15-minute epoch tick. After a stress test drives every provider down, those endpoints stay disabled and contaminate later tests until a pod restart. reset-all now re-enables them (mirroring the reset onto the Prometheus health gauge) and re-admits demoted providers via a cold rebuildPairingFromConfig (no re-probing). Every existing reset-all caller inherits this — no test migration.

For tests that only need the endpoint-health reset, POST /debug/reset-endpoint-health does exactly that and nothing else; its name mirrors Endpoint.ResetHealth() in the source. Response (any method other than POST returns 405):

{"reset": true, "endpoints_reenabled": 3}

/debug/reset-pairing and /debug/reset-scores remain available for targeted cleanup.

Releases

Releases are cut by pushing a semver tag matching vX.Y.Z (pre-release suffixes like v1.2.0-rc1 are allowed). The tag push triggers .github/workflows/release.yml, which builds the release artifacts.

git checkout main
git pull
git tag v1.2.0
git push origin v1.2.0

The release is created as a draft. After CI completes, open the Releases page, find the draft, and click Publish release to make it visible. Whether the release is marked as a pre-release is derived from the tag suffix: vX.Y.Z is a final release, vX.Y.Z-rc1 / -beta.2 / etc. are pre-releases. The draft gate is deliberate; flip the draft flag in .goreleaser.yaml to automate.

The :latest Docker tag only moves on final releases — RC and beta tags publish their per-version images but do not overwrite ghcr.io/magma-devs/smart-router:latest.

To re-run the release for an existing tag, go to GitHub → Actions → Publish Smart Router Release → Run workflow, passing the tag name as release_tag.

Artifacts

A release publishes:

Four statically-linked binaries attached to the GitHub Release: smartrouter-vX.Y.Z-{linux,darwin}-{amd64,arm64}, plus a sha256sum.txt checksum file.
A multi-arch Docker image at ghcr.io/magma-devs/smart-router:vX.Y.Z for linux/amd64 and linux/arm64.

The standalone Linux binaries and the binaries inside the Docker image are produced by the same go build invocation — same toolchain, same flags, byte-identical. GoReleaser owns the entire release-time build via the dockers_v2: block in .goreleaser.yaml.

Docker image tags

Tag	Source	Stability
`:vX.Y.Z`	release tag	immutable, byte-identical to the standalone binary at that version
`:latest`	release tag	floating — points at the most recent final release (not RC/beta)
`:main`	push to `main` branch	floating — most recent dev build from `main`, not a release artifact
`:<branch>-<version>`	push to other branches	per-branch build for testing

Customers should pin to :vX.Y.Z. :latest is for non-production "just give me the newest stable" use; :main is for previewing unreleased work from main.

The version string is injected at build time from the git tag — smartrouter version prints the tag verbatim, including the v prefix. Builds from non-tagged commits carry git describe output (e.g. v1.2.0-3-gabc1234), so a dev binary cannot masquerade as a release.

Pulling the image

Smart Router Docker images are published to GHCR:

docker pull ghcr.io/magma-devs/smart-router:vX.Y.Z

Tag conventions

Trigger pattern: v[0-9]+.[0-9]+.[0-9]+*. A tag like 1.2.0 (without the leading v) does not fire the workflow.
Follow semver MAJOR.MINOR.PATCH. For smart-router specifically:
- MAJOR — breaking change to the wire surface customers integrate with: HTTP metadata headers (e.g. Smart-Router-Version, Lava-Provider-Address), JSON-RPC envelope shape, removed/renamed CLI flags, removed/renamed config fields.
- MINOR — new capabilities: additional supported chains in specs/, new CLI flags, new metrics, new config fields with safe defaults, new HTTP metadata headers.
- PATCH — internal-only changes: bug fixes, performance improvements, refactors, dependency bumps, docs.
