We removed five Aptos methods that our Aptos nodes do not serve. Get account resources, Get account modules, Get account transactions, Get events by creation number and Get events by event handle need an indexer, and on Ankr they answer HTTP 500. No method limits, error codes or rate limits changed.
Sui GraphQL is available on Premium only, at https://rpc.ankr.com/premium-http/sui_graphql/YOUR_ANKR_API_KEY. We listed https://rpc.ankr.com/http/sui_graphql with the key appended, and that form answered -32052 API key is not allowed to access blockchain for every key. No method limits, error codes or rate limits changed.
We removed the Secret Network API reference from the docs. Ankr RPC stopped serving Secret Network in September 2025, and the pages stayed behind after the endpoints were retired. No method limits, error codes or rate limits changed on any other network.
We serve the Whitechain Sepolia testnet on rpc.ankr.com/whitechain_testnet over HTTPS. Whitechain is an OP Stack Layer 2 with WBT as its gas token. The chain is now in the chain list, with its own API reference.
Harmony mainnet reaches end of support on Ankr RPC. The Harmony network stopped producing blocks on 10 September 2026, after the Harmony team sunset its Layer 1 and announced a migration of the ONE token to Ethereum. We retire the rpc.ankr.com/harmony endpoint and remove Harmony from the chain list. No method limits, error codes or rate limits changed on any other network.
We serve Robinhood Chain mainnet on rpc.ankr.com/robinhood_mainnet to Premium and Enterprise users, over HTTPS and WSS. The chain is now in the chain list, with its own API reference.
Somnia mainnet is now a blockchain value on the Advanced API. Pass somnia_mainnet to the Token, NFT and Query methods, or omit blockchain and Somnia joins the multichain fan-out with every other supported network. We also corrected two testnet names in the supported-chain lists.
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.
Eighteen endpoints reach end of support on Ankr RPC on 15 September 2026. Seven networks go entirely, testnets included, and six testnets and variants go while their network stays. Seventeen of the eighteen already require a Premium key. The vFlow Volta testnet also answered keyless calls, so a keyless or Freemium integration that used it needs to move. Xai, Syscoin and Rollux are not served on the Advanced API either. No method limits, error codes or rate limits changed on any network that stays.
From 15 September Kaia runs on full nodes, and how far back a call can reach changes. Tracing keeps working for recent history, roughly a day of blocks, and a state read at an explicit older block needs archive state that a full node does not hold. Everything else on Kaia stays as it is: the same endpoints on mainnet and testnet over HTTPS and WSS, the same rate limits, the same error codes, and the same method list apart from the five listed below.
Sixteen networks stopped answering keyless and Freemium calls on 31 August, 29 endpoints across mainnets and testnets. They need a Premium key from now on. Sui JSON-RPC moved off the keyless endpoint and stays free on Freemium. Swell reached end of support. No method limits, error codes or rate limits changed anywhere else.
Redbelly mainnet has been answering on rpc.ankr.com/redbelly_mainnet since late August, and it was missing from the chain list, so the only way to find the endpoint was to be told about it. It is documented now, with its own API reference, and the reference is explicit about the standard EVM methods this node does not implement.
Allora, Botanix, Corn, Horizen EON, Moonbeam and Tenet reach end of support on Ankr RPC and are gone from the chain list and the docs. Mantle Sepolia testnet is delisted too, while Mantle mainnet is unaffected. No method limits, error codes or rate limits changed anywhere else.
