Uniswap Deploys v2, v3 and v4 on Hyperliquid's Elysium Network

Uniswap has deployed v2, v3 and v4 of its decentralized trading protocol on Elysium, the Hyperliquid-focused network built by Kinetiq that opened its public mainnet on Nov. 9. The deployment landed two days after that launch, with Uniswap confirming the move in a Nov. 11 post on X: "Uniswap v2, v3, and v4 are live on Elysium."

Uniswap's developer documentation lists contracts for all three versions, including the factories used by v2 and v3 and the PoolManager at the center of v4. The Elysium-specific v3 page identifies the network as chain ID 99901 and confirms HYPE as the token used to pay transaction fees.

What should integrators watch?

Uniswap warns developers against assuming contracts share the same addresses across chains. Integrators must check network-specific mappings before connecting applications.

The v3 deployment guide includes the factory, quoting contracts, position manager and other tooling. The v2 table lists an Elysium factory and router. For v4, the registry places Elysium in its mainnet section and lists PoolManager, PositionManager, Quoter, StateView and Universal Router contracts.

Elysium and HyperEVM have separate registry entries. HyperEVM runs on chain ID 999, Elysium on 99901, and the two networks carry different v4 PoolManager addresses.

What is Elysium's technical setup?

Kinetiq's public mainnet launched Nov. 9 using Arbitrum technology, with infrastructure provider Conduit, settling to HyperEVM inside the Hyperliquid ecosystem. The launch announcement cited 100-millisecond blocks and an execution target of 300 million gas units per second.

Solidity and Vyper contracts compile unchanged on Elysium, and developers can use standard Ethereum tooling including Foundry, Hardhat, viem and ethers. HYPE moves between HyperEVM and Elysium one-to-one as native gas, with no wrapper token, and HyperEVM ERC-20 tokens can bridge to Elysium permissionlessly. Kinetiq flagged spot trading, lending, derivatives, structured products and token launches as intended uses.

How do the three versions differ?

Uniswap Labs dates v2 to May 2020, when it introduced direct ERC-20 to ERC-20 trading, and v3 to May 2021. V3 brought concentrated liquidity: providers pick a price range, and a position stops earning fees when the market price exits that range, resuming if the price returns. Providers can hold multiple positions in one pool, each covering its own interval, and a position's balance can end up entirely in one asset as price moves through its range.

V4 keeps concentrated liquidity but consolidates management. A single PoolManager contract stores pool state, replacing v3's one-contract-per-pool model. Callers can batch balance-changing operations and settle obligations together, instead of v3's token transfers after each individual call.

The hooks system lets developers attach custom contracts to pools, running before or after swaps, liquidity additions and withdrawals. Each pool can carry one hook contract; a single hook can serve multiple pools. Hooks are optional, and their permissions determine which functions the PoolManager calls.

The original v4 rollout in January 2025 spanned 10 networks including Ethereum, Arbitrum, Base and Polygon. Uniswap Labs said that release followed nine independent audits and a $15.5 million bug bounty, with more than 150 hooks already built at launch.

Where does the network revenue go?

Kinetiq's November announcement committed 50% of sequencer revenue to buying back KNTQ, its native token, and 25% to builders whose applications generate Elysium blockspace demand. Teams can direct their share toward user incentives, liquidity programs, fee rebates or other application-level mechanisms. With Uniswap's contracts now live, the builder allocation gives application teams a direct revenue stake as Elysium's early DeFi activity takes shape.
