Reiy Finance is building an on-chain intent-based batch auction protocol on Sui. Instead of forcing users to choose a route, pool, or execution path, Reiy lets users express the result they want: sell this asset, receive at least this much of another asset, and protect the trade with clear constraints. These docs are for users who want protected trading, solvers and auctioneers who want to compete, and developers integrating with the protocol.

​

Who we are

Reiy is a protocol team focused on bringing trust-minimised batch-auction trading to the Sui ecosystem. The project combines Sui Move contracts (intent escrow, epoch lifecycle, on-chain scoring, hot-potato settlement), off-chain coordination services, a solver network, SDK bindings, and an indexer.

​

What Reiy helps with

• Users get protected execution: escrowed assets, SBBO admission floors, benchmark protection, and uniform surplus ratio across the batch.
• Solvers compete permissionlessly — gated only by an economic bond — to fill intents and earn rewards from verified surplus.
• Auctioneers compose Bids into Allocations and PairBenchmarks, and the on-chain contract selects the winner without off-chain authority.
• Apps integrate a higher-level intent interface instead of building routing logic from scratch.
• Operators get indexed protocol state, settlement events, and infrastructure patterns.

Why intents

A normal swap asks the user to choose execution details before the market has competed. An intent lets the user define constraints and lets specialized solvers compete to satisfy them. That separation matters because solvers can search liquidity, match compatible orders, take advantage of CoW opportunities, route leftovers, and settle only when the result satisfies the user’s minimum.

​

Why on-chain

Existing CoW implementations delegate winner selection, price verification, and solver coordination to off-chain services. Reiy moves every coordination guarantee on-chain — intent custody, solver scoring, winner selection, benchmark protection, and fairness enforcement — so the protocol outcome is verifiable by any participant, without trusting an off-chain operator.
