Back to all chains
Elysium Elysium is a high-throughput Arbitrum Orbit Layer 2 that settles to HyperEVM, runs co-located with HyperCore, and uses HYPE as native gas.
Elysium targets 100 ms blocks and execution throughput of 300 million gas per second, approximately 100 times HyperEVM’s small-block throughput. Transaction receipts are expected in around 300 ms. Gas fees are paid in native HYPE, bridged 1:1 from HyperEVM. Elysium mainnet supports production applications, while testnet provides an environment for testing contracts and integrations.
Elysium is purpose-built for high-frequency trading and professional market-making inside the Hyperliquid ecosystem, with quote refreshes up to 5–10 times a second. The chain is general-purpose EVM underneath, so any standard DeFi application runs on it too.
Start today with an Elysium mainnet or testnet node.
| Consensus | Built on Arbitrum Orbit (Nitro/ArbOS), Elysium uses one sequencer operated by Conduit. It settles on HyperEVM and uses an AnyTrust committee for data availability, with automatic fallback to posting full transaction data on HyperEVM. |
| Public / Private / Permissioned | Public and permissionless for users and developers. Validation is permissioned at launch, with a planned move to permissionless fraud proofs (Arbitrum BoLD), and sequencing is run by a single operator (Conduit). |
| Smart contracts | Yes |
| Smart contract language(s) supported | Solidity and Vyper, fully EVM-compatible — stock ArbOS at launch, the same contract environment as any other Arbitrum Orbit chain. |
| Transaction visibility | Public. Transaction records can be queried through RPC endpoints and viewed in the block explorer for the selected network. |
| Transaction visibility | Public. Transactions are queryable through the RPC and the Elysium testnet explorer. |
| Transaction ordering | Single sequencer. Transactions are ordered by priority fee within each block, with no privileged lanes for any transaction type — a quote update and a swap compete on the same fee basis. |
