# Single-Chain Architecture

> How Lidian handles stablecoin swaps within the same blockchain network.

## Overview

Single-chain swaps on Lidian are optimized for speed and efficiency. With no cross-chain delays, single-chain execution is ideal for entities who are already where they need to be, but need a different stablecoin.

## How It Works

### Atomic Execution

<Steps>
  <Step title="Request for Quote">
    Money mover's `request a quote` expressing their desired cross-chain intent (i.e bridge or swap)
  </Step>

  <Step title="Quote Creation">
    Liquidity providers `submit competitive quotes` for the cross-chain movement
  </Step>

  <Step title="Order Creation">
    Money Mover's select the best quote and `sign` the order. Once signed the signed order is submitted to the Lidian REST API
  </Step>

  <Step title="Execute, Fulfill, and Settle Order">
    The liquidity provider who agreed to the order or a verified relayer can `execute` the order on the source chain while also providing the tokens for the money mover.
    This executes, fulfills, and settles the orders in a sningel transaction.
  </Step>
</Steps>

### Delayed Fulfillment

<Steps>
  <Step title="Request for Quote">
    Money mover's `request a quote` expressing their desired cross-chain intent (i.e bridge or swap)
  </Step>

  <Step title="Quote Creation">
    Liquidity providers `submit competitive quotes` for the cross-chain movement
  </Step>

  <Step title="Order Creation">
    Money Mover's select the best quote and `sign` the order. Once signed the signed order is submitted to the Lidian REST API
  </Step>

  <Step title="Execute Order and Lock Tokens">
    The liquidity provider who agreed to the order or a verified relayer can `execute` the order on the source chain.
    This locks the money movers tokens.
  </Step>

  <Step title="Fulfill Order">
    The liquidity provider who agreed to the order `fullfills` the order on the source chain at a later time.
    Upon filling, this also settles at the same time.
  </Step>
