Elysium
Available for Premium and Enterprise users only.
Elysium API is available on Web3 API platform.
Elysium is a general-purpose Layer 2 for Hyperliquid built by Kinetiq. It runs on Arbitrum Orbit (Nitro), settles to HyperEVM, uses HYPE (18 decimals) as its native gas token, and produces a block about every 100 ms. The chain ID is 99901.
The examples on these pages run against mainnet, https://rpc.ankr.com/elysium/YOUR_ANKR_API_KEY. Over WSS, connect to wss://rpc.ankr.com/elysium/ws/YOUR_ANKR_API_KEY.
Your Web3 application reads Elysium data and sends transactions through an Elysium node, calling the methods of its API.
The API interaction follows the JSON-RPC which is a stateless, light-weight remote procedure call (RPC) protocol. It defines several data structures and the rules around their processing. It is transport agnostic in that the concepts can be used within the same process, over sockets, over HTTP, or in other message-passing environments. It uses JSON (RFC 4627) as data format.
Methods supported
web3_clientVersion: returns the current client version.web3_sha3: returns Keccak-256 (not the standardized SHA3-256) of the given data.net_version: returns the current network ID.eth_syncing: returns an object with data about the sync status or false.eth_gasPrice: returns the current price per gas in wei.eth_blockNumber: returns the number of most recent block.eth_getBalance: returns the balance of the account specified by address.eth_getStorageAt: returns the value from a storage position at an address specified.eth_getTransactionCount: returns the number of transactions sent from an address.eth_getBlockTransactionCountByHash: returns the number of transactions in a block specified by block hash.eth_getBlockTransactionCountByNumber: returns the number of transactions in the block specified by number.eth_getUncleCountByBlockHash: returns the number of uncles in a block specified by block hash.eth_getUncleCountByBlockNumber: returns the number of uncles in a block specified by block number.eth_getCode: returns code at a given address.eth_sendRawTransaction: creates new message call transaction or a contract creation for signed transactions.eth_call: executes a new message call immediately without creating a transaction on the blockchain.eth_estimateGas: generates and returns an estimate of how much gas is necessary to allow the transaction to complete.eth_getBlockByHash: returns information for the block specified by block hash.eth_getBlockByNumber: returns information for the block specified by block number.eth_getTransactionByHash: returns information on a transaction specified by transaction hash.eth_getTransactionByBlockHashAndIndex: returns information on a transaction specified by block hash and transaction index position.eth_getTransactionByBlockNumberAndIndex: returns information on a transaction by block number and transaction index position.eth_getTransactionReceipt: returns the receipt of a transaction by transaction hash.eth_getUncleByBlockHashAndIndex: returns information about an uncle of a block by hash and uncle index position.eth_getUncleByBlockNumberAndIndex: returns information about an uncle of a block by number and uncle index position.eth_getLogs: returns an array of all logs matching a given filter object.
Debug methods:
debug_traceBlockByHash: traces the execution of all transactions within a block specified by hash.debug_traceBlockByNumber: traces the execution of all transactions within a block specified by number.debug_traceBlock: traces the execution of all transactions within a block.debug_traceTransaction: traces the execution of a transaction specified by hash.debug_traceCall: traces a call executed on top of the state of a block specified, without creating a transaction.
Not available on Elysium:
The node exposes the debug, eth, net, rpc, and web3 modules. There is no trace_* and no arbtrace_*; for call traces use the debug_trace* methods above. See Unsupported methods for the full list.
