Live on Elysium testnet

Your own perps protocol, on your own chain.

Reactor is a complete perps protocol: matching engine, escrow, price oracle and verification, deployed on your chain through perps.studio. Your chain has a reason to be used from day one.

Value for every side of the market

A chain gets a perps protocol. Market creators get a fair place to list. Builders get a protocol to build on.

Start building

Hyperliquid's markets, on your chain.

A 2-of-3 committee signs Hyperliquid's prices. Reactor carries them to any EVM chain.

Two ways to launch with perps.studio

Reactor is a perps.studio project. Pick the one that fits what you are building.

White label

For teams that want their own exchange brand, fast. A fully branded perps exchange on Hyperliquid, HIP-3 dexes or Aster, live in minutes, with their markets and liquidity from day one and revenue on every trade.

Launch a white label

Reactor

For chains that want a perps protocol of their own. Matching engine, escrow, signed prices and verification, deployed on your chain, with room for market creators and builders to launch on it.

Trustless by design

The operator runs the engine. The chain holds the money, the prices are signed, and every commit can be checked.

Onchain escrow

Your USDC never leaves the escrow contract. Every ten minutes the venue commits its full state onchain: every balance, position and order.

See the contracts

Signed prices

Mark and funding are signed by a 2-of-3 committee reading Hyperliquid, so the operator cannot set a price. Venue markets use the committee; deployer markets use the committee or the deployer's own signed oracle.

How prices work

Disputes

Your browser replays each commit step by step, and an independent challenger does the same. A wrong commit is disputed onchain and the escrow freezes before it pays.

How verification works

From order to withdrawal

Fast where it can be, onchain where it has to be.

01
Match
Orders match in a Rust engine, off-chain, in microseconds.
02
Commit
Every ten minutes the engine posts its state to the escrow onchain.
03
Check
Anyone can replay the commit. Until it is final, it can be disputed.
04
Withdraw
Withdraw against your proof. If the escrow freezes, it still pays every account.
