Two days after Elysium opened its public mainnet, Uniswap showed up with all three of its major protocol versions ready to go. That kind of speed still surprises me. Most networks spend weeks or months waiting for core DeFi protocols to arrive, yet here the factory contracts, routers and the full v4 suite appeared almost immediately. Builders suddenly have options ranging from the original simple pools to the highly customizable hooks system, and they can pay for everything in HYPE.
What Exactly Arrived On Elysium
The announcement came through a straightforward post from the Uniswap account. Official deployment addresses for Uniswap v2, v3 and v4 are now live and listed in the developer documentation. No long wait, no phased rollout across different versions. Everything dropped at once on the new network.
Elysium sits inside the broader Hyperliquid ecosystem and uses chain ID 99901. It settles to HyperEVM, which itself runs under chain ID 999. The two networks keep separate entries in Uniswap’s registry, and their PoolManager addresses are different. That distinction matters for anyone writing integrators or multi-chain tools.
Official Contracts And Developer Guidance
Uniswap’s documentation for Elysium includes the expected pieces. For v3 you will find the factory, the quoting contracts, the position manager and the supporting tools needed to connect applications. The v2 side lists its own factory and router. Version 4 brings the PoolManager, PositionManager, Quoter, StateView and Universal Router.
One clear warning appears in the guides: never assume that contract addresses stay the same across chains. Every network receives its own set of deployments. Checking the network-specific mappings before writing any integration code is not optional. It is the only reliable way to avoid costly mistakes.
I have seen teams lose time because they copied an address from another chain and expected it to work. That habit dies hard, especially when a new network launches and everyone wants to move quickly. Taking five minutes to verify the official list remains the smartest first step.
HYPE As Native Gas And Fast Blocks
Elysium uses HYPE for gas. The token moves between HyperEVM and Elysium on a one-to-one basis without any wrapper. That design removes one common friction point. HyperEVM ERC-20 tokens can also bridge over permissionlessly, which should help liquidity form faster than on networks that require more complex bridging steps.
Block times sit around 100 milliseconds. The network targets roughly 300 million gas units per second. Those numbers put it in the high-performance category. Solidity and Vyper contracts compile without changes, so teams already comfortable with Ethereum tooling can keep using Foundry, Hardhat, viem and ethers.
That combination of familiar development experience and low-latency execution is what many builders have been asking for. You get the safety of battle-tested Ethereum tools plus the speed that makes interactive applications feel responsive.
How The Three Uniswap Versions Differ In Practice
Having all three versions available at the same time is more useful than it first appears. Each one serves a different style of trading and liquidity provision.
Uniswap v2 remains the simplest. It introduced direct trading between ERC-20 tokens and still works well for basic pairs and straightforward liquidity. Some teams still prefer it for its predictability and lower complexity.
Version 3 brought concentrated liquidity. Liquidity providers choose a price range in which their capital stays active. When the market price moves outside that range, the position stops earning fees until the price returns. Providers can open multiple positions in the same pool, each covering its own interval. As price moves through a range the balance of the two assets shifts, sometimes ending up as a single token.
That flexibility improves capital efficiency but also requires more active management. Not every user wants to monitor ranges constantly. For those who do, the fee earnings can be significantly higher than the old full-range model.
Uniswap v4 keeps concentrated liquidity and changes the architecture underneath. Instead of a separate contract for every pool, a single PoolManager stores the state of all pools. Callers can batch balance-changing operations and settle the net result at the end rather than transferring tokens after every individual call.
The real novelty sits in the hooks system. Developers can attach custom contracts that run before or after swaps, liquidity additions and withdrawals. Each pool can have one hook, and a single hook can serve many pools. Hooks are optional. Their permissions decide which functions the PoolManager actually calls.
During the original v4 launch across major networks, more than 150 hooks already existed. Dynamic fees, automated liquidity management and other custom behaviors became possible without forking the core protocol. That same flexibility now exists on Elysium from day one of the Uniswap deployment.
Why This Timing Matters For Builders
Elysium launched with a clear set of intended use cases: spot trading, lending, derivatives, structured products and token launches. Having Uniswap’s full suite available immediately removes one of the usual early barriers. Teams no longer need to wait for a major AMM to appear or to build their own temporary solution.
The network runs on Arbitrum technology with infrastructure support from Conduit. That pedigree gives many developers a baseline level of confidence. They already understand the security model and the tooling around it.
In my view the combination of fast blocks, native HYPE gas and three mature Uniswap versions creates a practical environment for experimentation. A team can start with a simple v2 pool for a new token, move to concentrated liquidity once volume appears, and later explore custom hooks for more advanced products. The migration path stays inside the same protocol family.
Kinetiq’s Revenue Sharing Model
Kinetiq, the team behind Elysium, outlined a revenue allocation that stands out. Fifty percent of sequencer revenue goes toward buying back KNTQ, the network’s native token. Another 25 percent is reserved for builders whose applications generate demand for blockspace.
Teams can direct their share toward user incentives, liquidity programs, fee rebates or other application-level mechanisms. That structure creates a direct link between network usage and support for the projects that drive it.
Earlier plans already mentioned this approach. The mainnet announcement confirmed the percentages. Whether the model proves sustainable will depend on actual sequencer revenue and how effectively the buybacks and builder allocations are executed. Still, the intent is clear: reward both token holders and the teams building useful applications.
Practical Considerations For Integrators
Anyone planning to deploy or integrate on Elysium should treat the official documentation as the single source of truth. Contract addresses differ from HyperEVM and from every other chain. Gas is paid in HYPE. Bridging for HyperEVM ERC-20 tokens is permissionless, which simplifies liquidity migration.
Because the network supports standard Ethereum tooling, existing deployment scripts and testing frameworks require only configuration changes. The biggest adjustment for many teams will be monitoring the new chain ID and updating any hard-coded network references.
I recommend starting with a small test deployment of a v3 pool or a simple v2 pair before moving larger amounts of capital. Early mainnet environments can still contain surprises even when the underlying technology is familiar.
What The Hooks System Enables
The hooks system in v4 deserves extra attention because it changes what is possible without leaving the Uniswap ecosystem. A developer can create logic that adjusts fees based on volatility, enforces certain trading conditions, or automatically rebalances positions. All of that runs inside the same PoolManager that handles the core accounting.
This approach reduces the need for completely separate protocols when a team wants customized behavior. Instead of forking and maintaining a full AMM, they can write a focused hook and attach it to one or more pools. The security surface stays closer to the audited core contracts.
Of course hooks introduce their own risks. Custom code still needs careful review. The difference is that the core pool accounting remains under the control of the audited PoolManager. That separation of concerns is one of the more elegant design choices in v4.
Looking At The Broader Context
Hyperliquid has built a strong reputation around its own trading environment. Elysium extends that ecosystem with a general-purpose execution layer that settles back to HyperEVM. Adding Uniswap’s protocols strengthens the DeFi surface area available to users who already operate in that environment.
The speed of the Uniswap deployment also sends a signal. Major protocol teams are willing to support newer networks quickly when the technical foundations look solid and the user base shows early interest. That willingness can accelerate the growth of an entire ecosystem.
At the same time, competition among high-performance chains remains intense. Fast blocks and low fees are necessary but no longer sufficient. The networks that attract sustained builder activity are usually the ones that make it easy to ship products and that provide clear economic incentives. Elysium’s revenue sharing model attempts to address the second point directly.
Key Takeaways For Different Audiences
For developers the main message is straightforward. Official Uniswap contracts are live. Documentation contains the addresses. Tooling remains familiar. Gas is paid in HYPE. Hooks are available if you need custom behavior.
For liquidity providers the choice of versions allows different strategies. Simple full-range positions remain possible through v2. Concentrated ranges and more active management are available through v3 and v4. The decision depends on time commitment and risk tolerance.
For traders the presence of mature AMM infrastructure means deeper liquidity is more likely to form quickly. The 100-millisecond block times should also improve the responsiveness of swaps compared with slower networks.
For observers watching the Hyperliquid ecosystem, the Uniswap launch reduces one common early-stage risk. Core trading infrastructure arrived almost immediately after public mainnet. That removes a frequent source of friction for new users and projects.
A Few Personal Observations
I have watched many networks launch over the years. The ones that succeed usually manage two things well: they attract serious builders early, and they keep those builders productive. Having three versions of Uniswap available from the start helps with both.
The decision to support the older versions alongside v4 also feels pragmatic. Not every project needs hooks on day one. Some simply need a reliable place to create a trading pair. Providing that option lowers the barrier for smaller teams and experimental tokens.
Whether Elysium becomes a lasting part of the DeFi landscape will depend on more than any single protocol launch. Sustained usage, reliable infrastructure and effective distribution of the builder incentives will matter more over the coming months. Still, starting with Uniswap already live is a strong opening move.
The documentation is public. The contracts are deployed. The tools work. Now it is up to the teams building on the network to turn that foundation into products people actually want to use. That part is always the hardest, and it is also the most interesting to watch.
Final Thoughts On The Deployment
Uniswap’s simultaneous launch of v2, v3 and v4 on Elysium removes a classic early-mainnet bottleneck. Builders gain immediate access to mature trading infrastructure, familiar development tools and the advanced customization options that hooks provide. Paying gas in HYPE and bridging assets from HyperEVM without wrappers further reduces friction.
Kinetiq’s commitment to direct a majority of sequencer revenue toward token buybacks and builder support adds an economic layer that many newer networks still lack. How effectively those mechanisms function in practice will become clearer as usage grows.
For now the practical reality is simple. The contracts are live, the addresses are published, and the network is open. Anyone with an idea for a trading application, a liquidity strategy or a custom hook has a ready environment in which to test it. That combination of readiness and flexibility is worth paying attention to.
