# Developer Guide

Trustless Work is **Escrow-as-a-Service** on **Stellar (Soroban)**.

Use it to deploy escrows, fund them, track milestones, and release funds. Your app drives the flow via **REST API** or **SDKs**.

{% hint style="info" %}
Most write endpoints return an **unsigned XDR**.\
You must sign it client-side with the correct **role wallet**.
{% endhint %}

### Pick your integration path

#### REST API

Use this if you want full control and you’re already signing Stellar transactions.

* [REST API: Introduction](https://docs.trustlesswork.com/trustless-work/api-rest/introduction)

#### React SDK (hooks)

Use this if you want typed hooks for every escrow action.

* [React SDK: Getting Started](https://docs.trustlesswork.com/trustless-work/escrow-react-sdk/getting-started)

#### Escrow Blocks SDK (UI blocks)

Use this if you want ready-made UI blocks and wallet connectivity.

* [Escrow Blocks SDK: Getting Started](https://docs.trustlesswork.com/trustless-work/escrow-blocks-sdk/getting-started)

### Quickstart (recommended order)

{% stepper %}
{% step %}

### 1) Get access

Request an API key. You’ll need it for deploy/fund/release/dispute flows.

* [Request API Key](https://docs.trustlesswork.com/trustless-work/introduction/developer-resources/request-api-key)
  {% endstep %}

{% step %}

### 2) Set up auth + signing

Wire up the auth header. Then get your wallet(s) ready to sign XDR.

* [Authentication](https://docs.trustlesswork.com/trustless-work/introduction/developer-resources/authentication)
  {% endstep %}

{% step %}

### 3) Learn the data model

You’ll use these types in every request/response.

* [Schema](https://docs.trustlesswork.com/trustless-work/introduction/developer-resources/schema)
* [Types](https://docs.trustlesswork.com/trustless-work/introduction/developer-resources/types)
  {% endstep %}

{% step %}

### 4) Implement the core flow

Typical sequence:

1. Deploy / initialize escrow
2. Fund escrow
3. Approve or update milestones (if used)
4. Release funds (or dispute + resolve)

Use the checklist to cover edge cases and role permissions.

* [Integration checklist](https://docs.trustlesswork.com/trustless-work/introduction/developer-resources/integration-checklist)
  {% endstep %}
  {% endstepper %}

### Prereqs (Stellar)

* [Testnet Tokens](https://docs.trustlesswork.com/trustless-work/introduction/stellar-and-soroban-the-backbone-of-trustless-work/testnet-tokens)
