Architecture

Reiy runs a hybrid system. The Reiy Protocol contracts on Sui hold custody and enforce every user protection. Fisherman, the off-chain Execution Coordinator, runs solver competition and signs the certificate that authorizes settlement. Solvers act as a meta aggregator, sourcing liquidity across Sui venues to fill intents. This page collects the diagrams for the whole system in one place.

System overview

Custody and protection live entirely in the contracts. Fisherman coordinates but never holds funds, and solvers can only move escrow by passing the contract’s checks.

Quote flow

A quote is a pre-trade price estimate. It does not move funds.

Auction and settlement flow

The end-to-end path from an open intent to a settled trade.

Settlement transaction

The winning solver settles in a single Sui programmable transaction block. Every check must pass or the whole transaction aborts and escrow never moves.

Auction round lifecycle

How Fisherman tracks a round off-chain.

Intent lifecycle

How a single intent object moves through its states on-chain.
