# Reiy Finance

Reiy Finance is an intent-based meta DEX aggregator on Sui. Instead of picking a pool or a route, you state the outcome you want, and solvers compete to fill it by aggregating liquidity across every Sui venue. The result is best execution with custody and a guaranteed minimum enforced on-chain.

Reiy is built from two layers that work together.

## What is Reiy Protocol?

Reiy Protocol is the on-chain layer: a set of Move contracts on Sui that hold your funds in escrow, admit each intent against a fair market floor, verify the winning solution, and settle it atomically. Custody and every user protection live here, so safety never depends on an off-chain operator.

## What is Fisherman?

Fisherman is the off-chain Execution Coordinator. It reads open intents, groups them into auction rounds, asks solvers to compete, ranks their solutions, and signs a certificate that lets the winning solver settle. Fisherman orchestrates competition but holds no funds and cannot override the contracts.

## How to use these docs

Reiy docs follow a question-oriented structure:

* **Concepts** explain what something is (for example, intents or how settlement works).
* **Tutorials** show how to do something (make a trade, run a solver).
* **Technical Reference** holds exact details (definitions, formulas, contracts, APIs, architecture).
* **Integrate** points developers and solvers to the right implementation path.
