Building on Elysium

Elysium is a standard EVM chain. Solidity and Vyper compile unchanged, and Foundry, Hardhat, viem, ethers, and standard JSON-RPC all work exactly as they do on any Arbitrum Orbit chain. Deploying is forge create or hardhat deploy against an RPC URL.

Testnet is live:

Mainnet is pre-launch. Its chain ID, public RPC endpoints, and block explorer are published at launch.

No required custom interfaces

Nothing Elysium-specific is required to deploy or run a contract. The Elysium-specific surfaces are opt-in capabilities:

• the HyperCore market-data precompile, for reading live HyperCore state;
• the ElysiumCoreWriter predeploy, for trading on HyperCore from Elysium.

Both arrive through an ArbOS network upgrade about four weeks after mainnet.

Fees

Fees are paid in HYPE and are low by construction. Data availability is committee-based rather than priced per byte on-chain, so the parent-chain cost per transaction is minimal. The fee environment is tuned so that a market maker refreshing quotes 5–10 times per second can do so cheaply and sustainably.

Market data is free at the point of use once the read precompile ships. Strategies that would pay continuous oracle-update gas elsewhere read fresh HyperCore state on Elysium for ordinary call gas.

Moving assets in and out

• HYPE bridges from HyperEVM 1:1 as native gas and withdraws 1:1.
• HyperEVM ERC-20s bridge to Elysium permissionlessly through the canonical bridge.
• Elysium-native tokens reach HyperEVM, and from there HyperCore, through the mirror bridge.

See Token bridging on Elysium for the full map.

Ordering

Transactions are ordered by priority fee within each block, with no privileged lanes. The protocol does not favor quote updates over swaps or the reverse, since AMMs on Elysium will not all look alike.

Ecosystem incentives

A builders allocation of sequencer revenue is reserved for ecosystem incentive programs for applications building on the chain. For integration questions or early access, contact the Kinetiq team.
