Uniswap Deploys v2, v3, v4 on Hyperliquid’s Elysium Network

Uniswap announced that its v2, v3 and v4 decentralized trading protocols are now live on Elysium, the Hyperliquid‑focused network that launched its public mainnet on Nov. 9. The deployments were confirmed in an X post on Nov. 11, with official contract addresses added to Uniswap’s developer documentation.

Deployment Details

The three versions each have dedicated contract sets. The v2 deployment includes a factory and router, while v3 adds a factory, quoting contracts, and a position manager. For v4, the registry lists a PoolManager, PositionManager, Quoter, StateView and Universal Router. All contracts are mapped to chain ID 99901, and developers are warned to verify network‑specific addresses.

Elysium Network Features

Elysium uses the native HYPE token for gas fees, with 100‑millisecond block times and a target throughput of 300 million gas units per second. HYPE moves between HyperEVM and Elysium on a one‑to‑one basis without a wrapper token, and ERC‑20 tokens on HyperEVM can bridge permissionlessly. The network runs on Arbitrum technology, with Conduit as the infrastructure provider.

Implications for Developers

Because Solidity and Vyper contracts compile unchanged, developers can use familiar tooling such as Foundry, Hardhat, viem and ethers. The v4 version introduces a single PoolManager contract and an optional hooks system that lets custom logic run at key pool events, potentially expanding the range of DeFi applications on Elysium.

Key facts

• Uniswap v2, v3 and v4 are live on Elysium (chain ID 99901).
• HYPE is the native gas token; blocks are 100 ms.
• Kinetiq allocates 50% of sequencer revenue to KNTQ buybacks and 25% to builders.
• Contracts are listed in Uniswap’s developer docs; addresses differ from other chains.
• Elysium settles to HyperEVM and uses Arbitrum tech with Conduit as provider.
