Uniswap v2, v3 and v4 Go Live on Elysium With HYPE Gas

Elysium said Uniswap v2, v3 and v4 contracts are now live on its layer-2 network, which uses HYPE as its “sole gas token” across the deployment. The deployments followed Elysium’s Nov. 9 public mainnet launch. Elysium described HyperEVM as “Hyperliquid’s smart-contract environment,” and HYPE moves from HyperEVM to Elysium one-to-one.

The result is one network carrying all three Uniswap protocol generations. It also gives application builders a single gas asset and chain identifier to use across those contracts.

What does the deployment change for developers?

For developers, the practical change is direct access to three Uniswap contract generations on one Elysium environment, with every integration using the same chain ID and native gas asset. The deployment includes factory contracts for v2 and v3 and the PoolManager contract for v4. Teams can use those contracts to build trading pools and liquidity tools on the network.

Elysium’s chain ID is 99901. That identifier gives transaction tooling a distinct reference for the network and separates Elysium from HyperEVM in configuration. The same chain ID and HYPE gas model apply across all three Uniswap deployments.

Version choice now matters at the design stage. A team can use the factory-based v2 or v3 contracts, or build around v4’s PoolManager. The update does not report live pools, assets, liquidity or trading volume. Contract availability should not be read as evidence of network adoption.

How does HYPE function across the two layers?

Elysium operates as the layer-2 network and settles its activity to HyperEVM. HYPE moves from HyperEVM to Elysium at a one-to-one ratio. Within Elysium, HYPE pays for gas as the native asset, and no second gas token serves that function.

For builders, that removes the need to plan around a separate Elysium gas coin. Integrations must fund transactions in HYPE and identify Elysium as chain 99901. The arrangement keeps the execution model centered on the same token used to move between HyperEVM and the layer-2 network.

The update specifies the one-to-one HYPE movement but does not set out a broader fee schedule. It also does not provide transaction-level gas data. Developers still need live network measurements before they can model how the deployment performs under sustained use.

What performance has Elysium set?

Kinetiq specified “100-millisecond blocks” and an execution target of “300 million gas units per second.” The block interval is a stated network specification. The gas figure is a target, not a measurement of live performance.

Kinetiq’s stated combination of 100-millisecond blocks and a 300-million-gas-units-per-second execution target defines a design specification, not proof of measured live throughput under real network conditions. That distinction matters because intended capacity and observed capacity answer different operational questions.

The first says what Elysium has been designed to process. The second shows what the network has processed in practice. Until live figures appear, the deployment cannot substantiate the gas target, although the 100-millisecond cadence gives integrators a concrete timing assumption to test.

What comes next?

The Uniswap deployments complete an earlier plan to support Uniswap on Elysium. Kinetiq plans a later upgrade that would let Elysium contracts access HyperCore market data and submit trades there.

The planned upgrade would link Elysium-hosted Uniswap contracts to HyperCore market data and trade submission, extending the network’s stated utility beyond the exchange contracts deployed today. It would connect contract execution to a broader trading workflow, according to the upgrade plan.

For now, the confirmed change is contract availability: v2 and v3 factories, the v4 PoolManager, HYPE-funded transactions and HyperEVM settlement on chain 99901. The source presents the HyperCore connection as a later upgrade and gives no rollout date. The next structural checkpoint is that connection, with no deadline announced.
