# Solver Integration

Solver integration means exposing the HTTP endpoints expected by the coordinator, registering on-chain, responding within auction windows, and settling winning certificates on Sui.

## Recommended path

1. Read [Solvers](/reiy-protocol/concepts/introduction/solvers) and [Fisherman](/reiy-protocol/concepts/introduction/fisherman).
2. Follow [Join as a Solver](/reiy-protocol/tutorials/solvers/join-as-solver).
3. Implement against the [Fisherman API](/reiy-protocol/reference/apis/solver-api) and the live [OpenAPI spec](https://testnet-fisherman.reiy.finance/openapi.json).
4. Use [Execute Settlement](/reiy-protocol/tutorials/solvers/execute-settlement) for the winning transaction flow.
5. Review [Solution Validation and Ranking](/reiy-protocol/reference/core/scoring-and-ranking) before returning solve responses.

## Integration requirements

* Public HTTP service URL configured for coordinator discovery.
* `/quote`, `/solve`, `/settle`, and `/notify` endpoints.
* Sui signing wallet for settlement.
* Idempotency handling for retries and notifications.
* Liquidity strategy that can satisfy protected minimums.
