# User Flow

> Follow the quote, intent, approval, execution, and settlement flow used by Utexo Swap.

## Swap workflow

The execution flow includes three participants:

| Participant  | Responsibility                                                                                             |
| ------------ | ---------------------------------------------------------------------------------------------------------- |
| **Partner**  | Integrates a wallet, application, exchange, or service with the Utexo API.                                 |
| **User**     | Owns the source assets, approves the swap conditions, and signs the required chain-specific authorization. |
| **Resolver** | Provides liquidity and fulfills the swap under the signed intent conditions.                               |

<Steps>
  <Step title="Request a quote">
    The user selects the source asset, destination asset, and amount. The partner calls `POST /quote`. Competing resolvers return a time-limited RFQ offer with pricing, fees, and execution constraints.
  </Step>

  <Step title="Create an intent">
    After the user accepts a quote, the partner calls `POST /intents` with the quote ID and the user's source, destination, and refund addresses. Utexo returns an intent ID and the approval mechanism required by the source network.
  </Step>

  <Step title="Collect chain-specific approval">
    The user signs the approval data locally:

    * EVM and Tron use Permit2.
    * Bitcoin uses a Partially Signed Bitcoin Transaction (PSBT) for an HTLC deposit.
    * Solana uses a cosigned versioned transaction.

    The partner submits the signed approval with `POST /intents/{id}/approvals`.
  </Step>

  <Step title="Execute the swap">
    Utexo notifies the selected resolver. The resolver executes the source-chain settlement action and transfers the destination assets to the user under the signed conditions.
  </Step>

  <Step title="Verify settlement">
    The wallet verifies the destination settlement. The partner can monitor progress with `GET /intents/{id}/status`, `GET /swaps`, or `GET /swaps/{id}`.
  </Step>
