Elysium mainnet is in the docs, for Premium and Enterprise

Ankr Team
Docs Team

We serve Elysium mainnet on rpc.ankr.com/elysium to Premium and Enterprise users, over HTTPS and WSS. The chain is now in the chain list, with its own API reference.

Docs​

  • Elysium is in the chain list. Elysium, the Kinetiq Layer 2 for Hyperliquid that settles to HyperEVM, carries the HTTPS and WSS endpoints, the MetaMask settings (chain ID 99901, HYPE), and the supported and unsupported method lists. The API reference documents 31 methods, including debug_traceBlockByHash, debug_traceBlockByNumber, debug_traceBlock, debug_traceTransaction and debug_traceCall.
  • Every example on those pages except the eth_sendRawTransaction placeholder was run against mainnet, and the response shown is the one it returned.

Worth checking on your side​

  • Premium and Enterprise only. The chain is not on the Freemium or Public plans. A request without an API key returns -32052.
  • WSS. Connect to wss://rpc.ankr.com/elysium/ws/YOUR_ANKR_API_KEY; eth_subscribe works, for example newHeads. See the WebSocket limits.
  • Blocks arrive about every 100 ms. The eth_getLogs window is capped at 10,000 blocks per call, which on this chain is under 17 minutes of history; a larger range returns -32062. Filter by address or topics: an unfiltered 10,000-block range on this chain returns tens of megabytes of logs. Page through long ranges, or subscribe to newHeads over WSS instead of polling.
  • There is no trace_*, arbtrace_* or arb_*. The node exposes the debug, eth, net, rpc and web3 modules. Use the debug_trace* methods with callTracer for call traces.
  • Filter methods are blocked. eth_newFilter, eth_newBlockFilter, eth_newPendingTransactionFilter, eth_getFilterChanges, eth_getFilterLogs and eth_uninstallFilter return -32075. Use eth_getLogs, or eth_subscribe over WSS.
  • No RPC method limits, error codes, batch caps or range caps changed on any other chain.
