Elysium Chain ID 99901, Gas Token and Network Facts

Elysium mainnet has chain ID 99901, pays gas in HYPE, and runs as an Arbitrum Orbit Layer 2 that settles to HyperEVM. This page lists the network values in one table, then shows how to read the latest Elysium block with Bitquery GraphQL without running a node. For every Elysium data page, start at the Elysium hub.

Elysium network facts

Property	Elysium (mainnet)	Elysium Testnet
Chain ID	99901 (hex 0x1863d)	99801 (hex 0x185d9)
Native token	HYPE, 18 decimals	HYPE
Stack	Arbitrum Orbit, running Arbitrum Nitro, with AnyTrust data availability	Same
Parent chain	HyperEVM, chain ID 999	HyperEVM testnet, chain ID 998
Bitquery network name	elysium in EVM(network: elysium); bid:elysium in the Trading cubes	Not indexed

An older chain from Vulcan Forged is also named Elysium and uses chain IDs 1338 and 1339. The elysiumTestnet preset in the viem library is that chain. Use chain ID 99901 for Kinetiq's Elysium.

Query Elysium with Bitquery

Bitquery indexes Elysium and serves its blocks, transactions, transfers and trades over one GraphQL endpoint (https://streaming.bitquery.io/graphql), with filters, sorting and aggregation. Any query can also run as a WebSocket subscription. To run these outside the IDE you need an API token: How to generate Bitquery API token ➤.

Bitquery data starts at block 6,149,924 (13 November 2026, 22:48 UTC). Earlier blocks are not in the API.

Latest block

Returns the newest block with its number, time, hash, gas used and transaction count. Block.L1 is the HyperEVM block that the Elysium block refers to.

Run this query in the IDE

query {
  EVM(network: elysium) {
    Blocks(limit: {count: 1}, orderBy: {descending: Block_Number}) {
      Block {
        Number
        Time
        Hash
        GasUsed
        BaseFee
        TxCount
        L1 {
          Number
          Time
        }
      }
    }
  }
}

Transactions, fees and transaction types

Transaction streams, HYPE fees in USD, counts by transaction type and block queries are on the Elysium Transactions & Blocks page. Elysium is an Arbitrum Orbit chain, so the Arbitrum system types 100, 104, 105 and 106 appear next to the usual EVM types. Type 106 is the internal transaction that starts each block, so filter it out with Transaction: {Type: {ne: 106}} when you count user activity.

FAQ

What is the Elysium chain ID?

Elysium mainnet uses chain ID 99901 (hex 0x1863d). Elysium Testnet uses chain ID 99801. In Bitquery the mainnet is EVM(network: elysium), and bid:elysium in the Trading cubes.

Is Elysium a Layer 2 on Ethereum?

No. Elysium is an Arbitrum Orbit chain that settles to HyperEVM (chain ID 999), the EVM chain of Hyperliquid. The Block.L1 fields in Bitquery hold HyperEVM block data for that reason.

Which token pays for gas on Elysium?

HYPE, bridged from HyperEVM. Fees in Bitquery are HYPE amounts with a USD value from the HYPE price.
