Changelog ​

User-visible changes to the platform — new chains, new transports, limit and error-shape changes. Newest first.

Changes that affect what your code sees (error shapes, limits, endpoints) are marked Breaking or Behaviour. Internal work — node operations, capacity, performance — isn't listed unless you'd notice it from the outside.

2026-07 ​

Dogecoin is available — /doge ​

https://rpc.au.ro/doge now serves dogecoind JSON-RPC, same shape as the rest of the Bitcoin family. See Dogecoin.

Cosmos Hub — corrected documentation Behaviour ​

No change to the service; the docs were wrong and are now correct. If you built against the old page, read Cosmos Hub again:

  • https://…/cosmos is the LCD REST API, not CometBFT JSON-RPC. A JSON-RPC POST there is answered {"code":12,"message":"Not Implemented"}; CometBFT paths like /cosmos/status return 501.
  • The CometBFT RPC (status, abci_query, subscribe, …) is served over WebSocket — wss://…/ws/cosmos.
  • /cosmos does not batch (it's REST — an array POST returns -32603).
  • CosmJS's Tendermint37Client cannot reach either transport; use the LCD, or gRPC for typed module queries.

Error catalog additions Behaviour ​

No new failure modes — these always existed and are now documented (Errors):

  • -32603 unexpected backend response format — a batch sent to a chain that isn't JSON-RPC.
  • -32603 no response for request id in batch.
  • -32700 failed to read request — distinct from invalid JSON-RPC request.
  • A chain path with no route returns a gateway 404 {"message":"no Route matched with those values"} — not -32601. -32601 means the chain is known but not served at your location.

WebSocket streaming — wss://…/ws/<chain> ​

Native subscriptions on eth, bsc, polygon, avax, solana, xrp, cosmos and cardano — you speak each chain's own subscription protocol; the stream itself is free (only the handshake is gated). See WebSockets.

gRPC — two entry ports ​

Native gRPC for Cosmos Hub and TRON. rpc.au.ro:8443 serves every call shape including server reflection; rpc.au.ro:443 handles unary + server-streaming with explicit descriptors. A ready-made cosmos.protoset is published. See gRPC.

Faster key revocation Behaviour ​

A revoked key now stops working within seconds at the proxy itself, even if the gateway's own credential lags — it answers 401 / -32012 API key revoked, and a revoked key inside a batch kills the whole batch before anything runs. See Security.

Honest per-location chain errors Behaviour ​

A chain the platform supports but that isn't served where you're connected now answers -32601 chain not available at this location: <chain> instead of a misleading backend error. Your key is fine — see Endpoints.

New reference pages ​

Platform limits, Support & SLA, Billing and a full per-chain Compute Units matrix.

Something changed and you're not sure why?

Every response carries an X-Correlation-ID. Quote it in a support ticket and we can trace the exact request.
