On NEAR mainnet, view_access_key_list now returns at most 100 keys per response, and an unpaginated request for an account with more than 100 keys fails. On Avalanche C-Chain, avax.getAtomicTxStatus is gone. Both changes come from upstream releases our nodes now run, nearcore 2.14.0 and AvalancheGo v1.15.2. We did not change any rate limits, and no other method limits, error codes, batch caps or range caps changed. nearcore 2.14.0 also carries NEAR's move to protocol version 88, with voting from 4 November. Ethereum mainnet is on reth v2.9.0, which runs a new EVM, and the x402 manifest now lists paid JSON-RPC on 126 networks, payable on Monad, Base or Solana.

Sui JSON-RPC now runs on a reduced method set: 26 methods on mainnet, none on testnet. Move to gRPC or GraphQL. Ankr Confidential RPC is live in demo phase, and safe on Ethereum mainnet now trails the head by 1 to 2 slots. Confidential RPC is a mode of Verifiable RPC: your SDK encrypts each call to an attested Intel TDX node, so Ankr's gateway relays bytes it cannot read. On Ethereum, safe follows the Fast Confirmation Rule instead of lagging about 13 minutes. Hoodi postponed Glamsterdam, and our Hoodi nodes run the releases that cancel the 26 October activation. Base Sepolia is on Denim, IOTA mainnet on protocol 38, and the docs now spell out WebSocket limits.

The safe block tag on Ethereum mainnet now follows the Fast Confirmation Rule (FCR). We upgraded our Ethereum consensus clients to Lighthouse v8.3.1 and turned FCR on. safe now typically points 1 to 2 slots behind the head instead of about 13 minutes behind it. Sepolia already ran FCR. Nothing changes in your requests: pass safe as you do today.

eth_sendTransaction now returns -32075 Method disabled on every EVM chain, instead of an error from the node. We never hold keys for you, so the method could not send a transaction before either; only the error you get back changed. Ethereum Sepolia activated Glamsterdam on 6 October, Filecoin mainnet moves to network version 29 and IoTeX mainnet to the Zanzibar hard fork on 19 October, and our nodes for all three already run the releases that carry them. XRP Ledger mainnet is on the rippled 3.4.1 security release. Whitechain Sepolia is on the Web3 API platform, the x402 manifest lists paid JSON-RPC routes, and Agent RPC MCP 0.2.4 is on npm and in the MCP Registry.

Filecoin's Calibration network activates network version 29 (Solstice) on 28 September at 12:59:30 UTC, and our Calibration nodes already run the release candidate that carries it. Sui mainnet moved to protocol 137, IOTA mainnet to protocol 36, and Ethereum mainnet and Sepolia to reth v2.6.0. We also corrected the 15 September end-of-support list: it now has eighteen endpoints, and one of the additions answered keyless calls.

Solana turned on Transaction V1 at the start of epoch 1035, on 15 September 2026 at about 01:00 UTC. Our nodes run Agave v4.2.2 and serve v1 blocks, so nothing changes on our side. Your side has one change to make: getBlock and getTransaction calls that still pass "maxSupportedTransactionVersion": 0 now fail with -32015 on almost every block, because almost every block already carries a v1 transaction.

Avalanche's Helicon upgrade activates on 22 September at 15:00 UTC, and our nodes already run the release that carries it. Core shipped an emergency hardfork, Sui moved to protocol 136, and Ethereum mainnet and Sepolia moved to reth v2.5.2. Separately, Solana activated Transaction V1 today, and that one needs a change in your client.

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.

Nine of these upgrades tracked a hard activation, where a node left on the old version stops following the chain. Taiko's Unzen fork and Somnia's Jig fork both activated inside this window and we landed ahead of both. Monad testnet activated MONAD_TEN on 12 August, and our nodes were already on the release that carries it. Nothing changed in RPC method limits, error codes or rate limits.
