Elysium

Get started

Building on Elysium

Deploying to Elysium with standard EVM tooling: no required custom interfaces, the contracts to start from, verifying contracts, and the infrastructure to build with.

Last updated

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 your Alchemy RPC URL.

Mainnet and testnet are live. See Connecting to Elysium for the chain ID, RPC endpoints, and explorer, and to add Elysium to your wallet.

No required custom interfaces

Elysium runs stock, off-the-shelf ArbOS (ArbOS 61 on mainnet and testnet), so the EVM baseline follows that version. Blob transactions are not supported.

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

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

Contracts

WHYPE and USDC are the canonical tokens; look-alike tokens exist, so check the address before you integrate one. Contract addresses lists them with Multicall3, the gateway router, the bridge contracts, and the standard deployments: Permit2, CreateX, the CREATE2 deployer, Disperse, and Safe.

Verifying contracts

Verify a contract’s source on the explorer’s Verify contract page, which also gives the Foundry and Hardhat settings to verify from your own tools.
