End of support for six chains, and Mantle Sepolia is delisted

Ankr Team
Docs Team

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.

Deprecations and end of support​

We removed six chains from the chain list and deleted their API reference pages. Inbound links now resolve to the chain list instead of returning a 404.

ChainStatus
AlloraEnd of support.
BotanixEnd of support.
CornEnd of support, mainnet and testnet both.
Horizen EONEnd of support.
MoonbeamThe Moonbeam team relaunched on Base. Their migration deadline was July 31, 2026, and the Polkadot parachain runs for about one month after that, so we are ending support for it.
TenetEnd of support.

This change removes the chains from the list, it does not flip a switch on the endpoints. If you still have any of these endpoints configured, treat them as unsupported and move off them: they can stop answering at any time, without a further notice here.

Mantle Sepolia testnet​

Mantle Sepolia is no longer listed, and the Mantle page now shows mainnet only. Mantle mainnet is not affected, and no Mantle mainnet method changed.

Worth checking on your side​

The three premium-only tracing methods on Mantle, debug_traceBlockByHash, debug_traceBlockByNumber and debug_traceBlock, were documented as Sepolia testnet only. They work on Mantle mainnet as well, so we dropped the testnet qualifier and retargeted the request examples at mainnet. If you skipped these methods because you read them as testnet only, they are available to you on mainnet with a Premium key.
