Uniswap has deployed versions 2, 3, and 4 of its decentralized exchange protocol on Elysium, a Layer 2 network built for the Hyperliquid ecosystem. The November 11 deployment arrived two days after Kinetiq launched the public mainnet on November 9, giving developers three distinct trading systems for building token exchange services and liquidity pools. Because the three versions span automated pools, concentrated liquidity, and hook-based pool management, the rollout puts the protocol's full design range in front of a builder community that is only days old.

Uniswap confirmed the expansion in an X post and directed builders to its official contract addresses:

Uniswap v2, v3, and v4 are live on Elysium

Contract Addresses and Network Settings

In the developer registry maintained by Uniswap, the contracts for each version are listed. Version 2 comprises a factory and a router; version 3 includes a factory, a position manager, and a pricer; and the version 4 listing covers PoolManager, PositionManager, Universal Router, Quoter, and StateView.

Elysium operates under chain ID 99901, with HYPE used to pay network transaction fees. The settlement environment, HyperEVM, carries its own chain ID of 999, and the networks maintain different v4 PoolManager addresses. Uniswap has asked developers to verify the correct contract addresses for each network before integrating, since an application may connect to the wrong contract if it uses an address from another chain. The registry offers the required address mappings for integration. Keeping the two address sets separate is the main integration safeguard for teams that plan to move HYPE between the environments, a transfer that can be done one-to-one without wrapping.

How the Three Versions Work

Version 2 introduced automated liquidity pools for direct token swaps. Launched in May 2020, the model enables trading without a traditional order book: users swap assets against liquidity supplied by liquidity providers.

Concentrated liquidity followed with version 3 in May 2021. Liquidity providers set price ranges for their positions instead of spreading funds across all possible prices, which can support efficient capital utilization within the selected range. Positions cease earning fees once the price moves outside the range, and fee income resumes when prices return. Providers can also distribute their funds across several price ranges.

Version 4 retains concentrated liquidity while changing pool management. The PoolManager contract keeps information about pools in a single contract rather than requiring a separate contract for every pool, and it allows joint settlement of balances. Version 4 also permits hooks to execute custom code before and after trades and liquidity actions. Hooks can be used for fee adjustment, automated management, and many other pool properties, with their settings defining when they occur.

Read as a set, the three releases give builders a progression of control: pooled swaps without an order book in v2, liquidity concentrated at provider-chosen price ranges in v3, and pool behavior programmable through hooks in v4.

What Kinetiq's Elysium Network Offers

Elysium, Kinetiq's public mainnet, launched on November 9 using Arbitrum technology and Conduit-run infrastructure. Kinetiq positions the network as a high-performance Layer 2 built for the Hyperliquid ecosystem. Transactions on Elysium settle to HyperEVM and run side by side with HyperCore.

According to Kinetiq, Elysium produces 100 millisecond block times and 300 million gas per second. Gas is the measure of computational work that smart contracts perform.

Kinetiq states that Solidity and Vyper contracts run unchanged on the network. Developers can use well-known Ethereum development tools such as Foundry, Hardhat, Viem, and Ethers to deploy applications. For teams with existing Ethereum codebases, that compatibility is the practical entry point: contracts and the standard tooling around them carry over unchanged, leaving the registry's Elysium address mappings as the main adaptation step. HYPE can be transferred from HyperEVM to Elysium one-to-one without wrapping, and supported ERC-20 tokens can also be bridged from HyperEVM. Spot trading, lending, and derivatives are among the planned use cases.

Sequencer Revenue Committed to Developers

Kinetiq has committed 50% of its sequencer income to repurchasing KNTQ, its native token. An additional 25% of income will reward developers whose applications create traffic within the network, with both allocations dependent on income earned. Because the allocations scale with income, the size of developer rewards will track the activity that applications actually generate.

Ken Ng, ecosystem lead at Uniswap Labs, noted that the protocol is part of Elysium's launch infrastructure. Ng highlighted market creation, liquidity provision, and hooks as key capabilities, and pointed to integration with HyperCore as one way to utilize live market data in the future.

With the launch, builders have access to three generations of the Uniswap protocol on Elysium, spanning automated liquidity pools, concentrated liquidity, and hook-based pool management. Trading volume and liquidity will be determined by the level of actual traffic on the network, and no deposit amounts into the newly created liquidity pools have been disclosed. In the near term, the observable markers are concrete: correct address usage across chain IDs 99901 and 999, the arrival of the planned spot trading, lending, and derivatives use cases, and how builder activity responds to the sequencer-income reward split.
