Centralized-exchange liquidity, settled on-chain.
HyFi — Hybrid Finance — is a prop-AMM platform that lets professional market-makers stop losing to toxic flow, and gives the best prices to traders.
Two fundamental truths
DeFi liquidity has a pricing problem.
Most LPs lose money because of toxic flow.
Toxic flow exists because AMMs aren’t aware of CEX prices. Arbers’ profits are taken from LPs.
Users don’t care about decentralization.
99% of users just want the best prices for trades on-chain.
What is a propAMM?
One operator. Live prices. No stale curve.
A proprietary AMM is an AMM where a sophisticated operator provides the liquidity and controls the pricing logic — offering lower slippage and better prices. It's why propAMMs already dominate Solana's DEX volume. HyFi makes them viable on EVM. Everything is on-chain — no RFQ.
A shared oracle pushes fresh prices on-chain
Price updates and MM token inventory live on-chain and refresh every few seconds. No single market-maker has to fund their own update stream — the infrastructure is pooled.
Each market-maker ships their own Quoter
MMs run custom on-chain code for any MMing strategy — shaping a curve around the live price, reacting to their own inventory etc. Proprietary logic, fully on-chain.
Routers settle through the Uniswap v4 hook
As a UniV4 hook, HyFi is reachable from every router that integrates v4 hooks. Trades run through UniV4 itself, guaranteeing the user’s minimum output. Traders’ tokens are never held on HyFi, only UniV4 itself.
One platform — everybody wins.
HyFi is the platform that hosts and routes to many market-makers — it is not itself a market-maker.
For market-makers
Lower the cost of making markets on-chain.
Lower cost to operate
A shared pricing oracle pushes fresh prices on-chain every few seconds — no MM funds their own update stream.
Trading flow out of the box
Join HyFi and reach every aggregator that integrates the hook — on day one, now and in the future.
Custom strategies, on-chain
Ship your own Quoter to mirror your CEX logic, shape a curve around the live price, and react to inventory.
Greatly reduced risk
No impermanent loss, no loss to toxic flow — risk is eliminated by construction, not patched after the fact.
For traders & aggregators
CEX-grade pricing, one integration away.
CEX-grade pricing on-chain
Swaps are priced against live CEX prices and order-book depth, so spreads and slippage track real CEX liquidity.
One integration, many MMs
Integrate HyFi once and reach every market-maker on the platform — now and as new ones join.
No new trust assumption
Settlement runs through Uniswap v4’s PoolManager with your minimum-output check. Bad price? The swap reverts.
A single venue
One place to plug in, one place to route to — and a network effect that compounds for everyone on the platform.
Impermanent loss, by construction
On-chain price refresh cadence
On-chain — prices & MM inventory
