Ankr spreads your requests across a decentralized node network. Smart Router is a control plane you own that chooses upstreams, verifies responses, and keeps you online across every provider, including Ankr. "Decentralized" and "controlled by you" are not the same thing.
Ankr is interesting to compare against Smart Router, because Ankr already markets a form of routing: requests spread across a decentralized network of independent node operators. So a fair objection is, "if Ankr is already distributed, why would I need a routing layer on top?" It's a good question, and the answer is the whole point of this post.
Short version: distributing requests across Ankr's network is not the same as owning the control plane that governs your providers. Ankr is still one provider relationship, one API contract, one view of correctness. Smart Router is the layer that sits above all of your providers, Ankr included, and gives you failover, validation, caching, and observability that you control. They're not substitutes.
"Decentralized" solves a different problem than "controlled by you"
Ankr's decentralized network is a real strength for availability: if one node operator drops, others can serve the request, and you're not tied to a single data center. That addresses the "one machine goes down" failure mode well.
But there are failure modes it doesn't address, because from your application's perspective Ankr is still a single upstream:
- Single API relationship. If Ankr's gateway, auth, or the specific endpoint you use has an incident, you have no independent second path. Decentralization behind the endpoint doesn't help if the endpoint itself is your only route.
- Single view of correctness. A decentralized network can still return a response that's stale at chain tip or wrong for a given method. Being served by many operators doesn't mean the answer was cross-checked against a different provider.
- No control plane you own. The routing logic lives inside Ankr. You don't set the failover policy, the validation quorum, or the caching behavior, and you can't observe it in your own metrics.
That's the gap. Ankr decentralizes its infrastructure. It doesn't give you a control plane over your providers.
What each product actually is
Ankr answers: "Where do I get my on-chain data?" A Web3 infrastructure provider serving RPC across many chains via a distributed node network, plus additional services. You point your app at Ankr and get blocks, balances, logs, and transaction results. From your app's side, it's one provider endpoint.
Smart Router answers: "How do I make every provider I use reliable and trustworthy, on my terms?" A control plane between your app and one or more RPC sources. It selects the best upstream per request, fails over on degradation, cross-validates responses across providers, caches reads, and instruments the whole path. It's provider-agnostic: Ankr, Alchemy, QuickNode, Infura, self-hosted nodes, all orchestrated together, under your policy.
One is a source of truth. The other is the layer you own that manages your sources of truth.
Why one upstream, decentralized or not, hits a ceiling
Any single upstream is a single point of trust for your application, even one backed by many operators. When it returns something stale or incorrect, your app has no second opinion. And a provider can be "up" and still be wrong: slow on one method, stale under load, inconsistent by region. Uptime tells you it answered, not that the answer was correct, and across production systems, a large share of incidents trace back to RPC and node issues rather than app bugs.
You could add a second provider alongside Ankr, but then you inherit the hard part yourself: deciding when to switch, catching non-obvious failures, reconciling provider differences, and validating the data. That glue code is exactly what Smart Router is.
What Smart Router adds, and who controls it
Unlike routing that lives inside a provider, Smart Router's logic is yours to configure and observe:
- Automatic failover on real degradation, unavailable, erroring, stale, or timing-out upstreams get routed around automatically, on policies you set.
- Cross-validation sends reads to several upstreams in parallel and returns only once a quorum agrees, blocking a single provider's conflicting or malicious response from reaching your app. This is the layer that protects against bad data, and it requires a different provider to check against, something a single decentralized network can't give you.
- Block-aware caching serves repeat reads from a cache that understands block height, cutting upstream calls without serving stale data. Shared across replicas, it reduces spend and latency.
- Transaction broadcasting fans writes like
eth_sendRawTransactionout to all eligible upstreams in parallel to raise success rate and speed. - Multi-chain by config, JSON-RPC, REST, gRPC, Tendermint, and WebSocket across EVM chains, Solana, UTXO chains, Cosmos chains, and more, defined by JSON specs, so adding a chain needs no code change.
- Full observability, Prometheus metrics, OpenTelemetry traces, structured logs, a typed error taxonomy, and a prebuilt dashboard across every provider at once, in your own stack.
Teams report roughly 99% fewer RPC errors and 50 to 70% fewer upstream calls after adding this layer. It runs in production behind teams like Kraken, Fireblocks, GK8 by Galaxy, and Hypernative.
Side-by-side
| Ankr | Smart Router by Magma Devs | |
|---|---|---|
| Category | RPC provider (decentralized node network) | RPC orchestration & security layer |
| Position in stack | A source of on-chain data | Sits between your app and one or more sources |
| Who controls routing | Ankr, inside its network | You, across every provider you configure |
| Providers | Ankr's own network | Provider-agnostic: Ankr, Alchemy, QuickNode, Infura, self-hosted, etc. |
| Cross-validation of responses | Within one network's view | Quorum-based validation across different providers |
| Caching | Provider-side | Block-aware cache you control, shared across replicas |
| Observability | Ankr dashboard for Ankr traffic | Unified metrics/traces/logs across all providers |
| Deployment | Managed service | Self-hosted / source-available, or managed |
| Vendor lock-in | Tied to one provider relationship | Reduces dependence on any single provider |
The decentralization Ankr offers lives in the "Providers" and "Position in stack" rows, it's about being a resilient source. Every other row is about you governing multiple sources, which is Smart Router's job.
If you're on Ankr, here's the move
Keep Ankr as one upstream, the decentralized network is a genuinely good primary. Then add a second provider (or your own nodes) and put Smart Router in front of all of them. Now you get a second opinion via cross-validation, instant failover you control, caching that cuts your Ankr usage 50 to 70%, and unified observability in your own metrics, the things a provider-internal router structurally can't give you.
The teams that can skip this are early-stage or low-risk apps where brief hiccups and single-relationship dependence are fine. If downtime or bad data has real cost, exchanges, custodians, security platforms, high-value DeFi, a single provider relationship, decentralized or not, is still a single point of trust.
The bottom line
Ankr decentralizes the infrastructure behind your endpoint. Smart Router gives you the control plane over your providers, failover, cross-validation, caching, and observability on your terms, across Ankr and anything else you run. "Decentralized RPC" and "a routing layer you own" solve different problems, so it's not Ankr vs. Smart Router. Keep Ankr, and put Smart Router in front of it.
