Uniswap launches v2, v3 and v4 on Hyperliquid’s Elysium network

Uniswap has launched v2, v3, and v4 on Elysium, bringing three versions of its decentralized trading protocol to the Hyperliquid-focused network two days after its public mainnet debut.

Summary

Three Uniswap versions are live on Elysium, with official contract addresses available for developers.
Elysium uses HYPE for gas and settles to HyperEVM within the Hyperliquid ecosystem.
Kinetiq has committed 50% of sequencer revenue to KNTQ buybacks and 25% to builders.

Uniswap announced the deployments in a Nov. 11 X post, telling builders they could find the official addresses in its developer documentation. “Uniswap v2, v3, and v4 are live on Elysium,” the account wrote.

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

Uniswap publishes Elysium contract addresses

In its v3 deployment guide, Uniswap warns developers against assuming that contracts share the same addresses across different chains. Integrators are instructed to check the network-specific mappings.

The guide includes the v3 factory, quoting contracts, position manager, and other tools used to connect applications to the protocol. Uniswap’s separate v2 deployment table lists an Elysium factory and router.

For v4, the deployment registry places Elysium in its mainnet section and lists a PoolManager, PositionManager, Quoter, StateView, and Universal Router contracts.

Elysium and HyperEVM have separate entries in the registry. HyperEVM uses chain ID 999, while Elysium uses 99901, and their v4 PoolManager addresses differ.

Elysium launched with HYPE gas and 100-millisecond blocks

As crypto.news previously reported, Kinetiq’s public mainnet launch took place on Nov. 9. The network uses Arbitrum technology, operates with infrastructure provider Conduit and settles to HyperEVM.

In its launch announcement, Kinetiq described 100-millisecond blocks and an execution target of 300 million gas units per second. Gas measures the computational work required to run transactions and smart contracts.

According to the company’s announcement, Solidity and Vyper contracts compile unchanged on Elysium. Developers can use familiar Ethereum tools, including Foundry, Hardhat, viem and ethers.

HYPE moves between HyperEVM and Elysium on a one-to-one basis as native gas without a wrapper token, Kinetiq said. HyperEVM ERC-20 tokens can bridge to Elysium permissionlessly.

The company identified spot trading, lending, derivatives, structured products and token launches among the network’s intended uses.

Uniswap v4 supports custom pool behavior

The three versions offer different approaches to trading and supplying liquidity. Uniswap Labs’ protocol overview dates v2 to May 2020, when it introduced direct trading between ERC-20 tokens, and v3 to May 2021.

With v3, liquidity providers can choose a price range in which to put their funds to work. Uniswap’s concentrated-liquidity documentation explains that a position stops earning trading fees when the market price moves outside that range. Fee earnings resume if the price returns to it.

Liquidity providers can hold several positions in the same pool, each covering its own price interval, the documentation says. As trading moves the price through a position’s range, the balance between its two assets changes and can eventually consist entirely of one asset.

Uniswap v4 retains concentrated liquidity while changing how pools are managed. Its technical documentation describes a single PoolManager contract that stores pool state, compared with v3’s separate contract for each pool.

Uniswap’s comparison of the two versions says v3 requires token transfers after each individual call to a pool. In v4, the caller can combine balance-changing operations and settle the resulting obligations together.

The version’s hooks system lets developers attach custom contracts to pools. Hooks can run before or after swaps, liquidity additions, and withdrawals. Each pool can have one hook contract, while a single hook can serve multiple pools.

Hooks are optional, according to the developer guide, and their permissions determine which functions the PoolManager calls. Developers can choose the stages at which their custom logic runs, including when a pool is first initialized.

During the initial v4 rollout in January 2025, Uniswap Labs launched the protocol across 10 networks, including Ethereum, Arbitrum, Base and Polygon.

Uniswap Labs said the original v4 release followed nine independent audits and a $15.5 million bug bounty. At that launch, developers had already built more than 150 hooks, including tools for dynamic fees and automated liquidity management.

Kinetiq commits network revenue to buybacks and builders

Kinetiq’s earlier Elysium plans, unveiled in August, included an allocation of sequencer fees to token purchases and application developers.

The November mainnet announcement committed 50% of sequencer revenue to buying back KNTQ, Kinetiq’s native token. A further 25% is allocated to builders whose applications generate demand for Elysium blockspace.

Kinetiq said teams can direct their share toward user incentives, liquidity programs, fee rebates or other application-level mechanisms.
