Roundup: MONAD_TEN, Sui protocol 135, and the moved Agentic RPC paths now answer 301

Ankr Team
Docs Team

Monad's MONAD_TEN activates on mainnet on 2 September at 14:30 UTC, and our nodes are already on the release that carries it. Sui moved to protocol 135 and Stellar to Protocol 28. On the docs side, the four Agentic RPC pages that moved to a top-level section now answer with a real 301 instead of a page that says 200 and redirects in the browser, and that includes the Markdown twin an agent fetches.

Docs​

  • The moved Agentic RPC paths redirect properly. /rpc-service/mcp/, /rpc-service/mcp/agent-rpc/, /rpc-service/torpc/ and /rpc-service/mcp/management/ now answer 301 at the CDN, and so does the index.md twin of each. Before this, the old HTML path answered 200 and redirected in the browser, so a person saw nothing wrong and a link checker saw success, while the Markdown twin an agent fetches returned an error on exactly the pages written for agents.
  • The tier tables now describe what the proxy actually does. Tier 1 is not a mechanical passthrough: it renames fields, returns numbers in decimal, and already drops logsBloom. Tier 2 adds the ABI decode on top of that shape, and nothing else. The token figures on TORPC all come from one live production run rather than from a range, and the reference decoder is named where it was previously described as unpublished: @w3tech.io/torpc-decoder.
  • Batch behavior is documented. A batch response carries one Token-Tier header for the whole array, and it reports the minimum tier applied across the elements. An element can be decoded further than the header says, so read each element's tier from its shape.
  • gRPC data transfer is metered in both directions. The pricing page and the service plans said "receiving data" and charged per GB received. The meter counts the request you send as well as the response you receive, and the tables now say so. The credit rate did not change.

Network upgrades​

Each of these has an activation height or date, and the upgrade landed before it:

  • Monad: mainnet nodes on v0.16.1, which sets the MONAD_TEN activation for mainnet at 2 September 14:30 UTC. Upstream flags it mandatory: a node still on v0.16.0 after that instant keeps applying MONAD_NINE rules and diverges.
  • Sui: mainnet nodes, testnet nodes and validators to mainnet-v1.78.1 and testnet-v1.78.1, which carry protocol version 135.
  • Stellar: nodes moved to Protocol 28, running Horizon 28.0.1.

Client versions​

Deprecations and end of support​

Nothing new closed in this window, and the standing items still stand:

  • Sui JSON-RPC. The implicit fallback to the Sui Foundation archival service disconnects at the end of September 2026, after which historical and pruned reads over JSON-RPC can return incomplete results. Sui is also removing the JSON-RPC interface from its node software, so treat JSON-RPC as a path with an end date and migrate to gRPC or GraphQL.
  • Allora, Botanix, Corn, Horizen EON, Moonbeam and Tenet reached end of support earlier this month and their API reference pages are now gone from the docs as well. Inbound links resolve to the chain list.
  • Bahamut remains unserved after the network was discontinued.

Worth checking on your side​

  • Browser JavaScript can read the tier header now. Preflight accepts Accept-Token-Tier, Rpc-Compress and Rpc-Decode, and the response carries Access-Control-Expose-Headers: Token-Tier. This is live on rpc.ankr.com, rpc.blockrail.com and enterprise.onerpc.com. Until this landed, browser code could negotiate a tier and had no way to read which one it got, so if you gave up on that, try again.
  • If you turned on tier 1 from our previous description, re-check your parser. Field names and number formats differ from tier 0, and logsBloom is not there. That was always the behavior; the docs were wrong about it.
  • Refetch the descriptor if you cached it. rpc.ankr.com/.well-known/torpc.json lists ten methods that reach tier 2. It previously listed eight, which did not match the docs or the proxy.
  • Monad mainnet. MONAD_TEN activates on 2 September at 14:30 UTC. Our nodes are ready. If you run your own Monad node behind the same integration, upgrade it before then.
  • The SDK carries a dependency fix. @ankr.com/ankr.js 0.7.0 is on npm with an axios upgrade that clears 27 advisories, published with a provenance attestation. The quickstarts install the SDK unpinned, so a fresh install picks it up.
  • No RPC method limits, error codes, batch caps or range caps changed in this window.
