REACTOROnchain escrow
Your USDC never leaves the escrow contract. The venue periodically commits its full state onchain: every balance, position and order.

Ship with perps.
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.
Run it your way.
Hyperliquid's price feeds or your own, your leverage limits, and third-party markets and front ends when you want them.
Price feeds
Hyperliquid's, signed 2 of 3, to launch fast. Or your own oracle for any asset.
Leverage
Your limits and margin tiers, market by market.
Market creators
Let third parties list markets and keep up to half their fees. Or list them all yourself.
Front ends
Let third-party front ends earn builder fees on the orders they route. Or run only yours.
Exchange speed. Onchain settlement.
Orders match off chain in microseconds. Everything the engine does is committed, checked and paid out on your chain.
01
Price
Hyperliquid's feeds, signed 2 of 3, or your own.
02
Match
A Rust engine matches orders in microseconds.
03
Commit
Periodically, the full state is committed onchain, every span pre-checked in the verifier.
04
Verify
Anyone replays it. A wrong root freezes payouts.
05
Withdraw
By Merkle proof, even if the operator vanishes.
The operator runs the engine and posts a stake. The chain holds the money, the prices are signed, and every commit can be checked.
Signed prices
Mark and funding are signed by a 2-of-3 committee reading Hyperliquid, so the operator cannot set a price, and a signed mark moves a market at most 10% at a time. Venue markets use the committee; deployer markets use the committee or the deployer's own signed oracle.
How prices workDisputes
Your browser replays each commit step by step, and independent challengers do the same. A wrong commit is disputed onchain against the operator's stake: a defender answers within two hours or pays the challenger from it, and a proven wrong step freezes the escrow before it pays.
How verification worksThe live testnet, release v12.0.1 on Elysium. Every contract is source-verified on the Elysium explorer and Sourcify.
