📰Solver integration

1. Introduction

A Solver is a service node responsible for providing quotes and executing exchanges.

The platform will request quotes from multiple Solvers simultaneously, select the Solver with the best quote, and then the selected Solver will independently complete the exchange for that order.

---

2. Integration Process

A Solver needs to implement the following four APIs:

API	Direction
Solver Quote API	Platform → Solver
Solver Order API	Platform → Solver
Solver Order Notification API	Platform → Solver
Solver Settlement Notification API	Platform → Solver

At the same time, the Solver needs to call the following two APIs provided by the platform:

API	Direction
Solver Submit Order API	Solver → Platform
Solver Query Order API	Solver → Platform

3. Workflow

Platform
 │
 ├──► Request quotes from multiple Solvers
 │
 ├──► Select the best Solver
 │
 ├──► Create order
 │
 ├──► Notify Solver to create order
 │
 ▼
User deposits tokens
 │
 ▼
Platform confirms deposit
 │
 ├──► Notify Solver to start execution
 │
 ▼
Solver sends tokens to user
 │
 ├──► Submit transaction hash
 │
 ▼
Platform verifies transaction
 │
 ▼
Platform settles funds to Solver

4. Authentication

All Solver requests to platform APIs must include the following parameters.

(solverCode and solverSecret need to be obtained from the platform.)

Parameter	Description
solverCode	Solver identifier
solverSecret	Solver authentication key
timestamp	Current timestamp in milliseconds
