# What do we need

In order to become a native Sell provider in the  ecosystem, you must:

### Adapt to our Backend

- Adapt your API and endpoints to interact with our Backend.
- Generate a structured payload and a signature with a specific format.
- Send your public key to Ledger and secure your private key.

### Develop/Modify your LiveApp

- Use our Ledger Exchange Services Kit in addition to the  API.
- Provide a set of query parameters to access your LiveApp directly with the quote entered by the user in .
- Write/Modify the Manifest file.
- Follow some flow/UX requirements.

### Test and submit

Test end-to-end your integration by manually loading your LiveApp through Developer Mode (see [Wallet API doc](../discover/dapp-browser/manifest#load-your-live-app-locally-on-desktop)) and submit:

- Your API
- Your LiveApp Manifest
- Your public key

In the following pages, you will find:

- [Architecture](sell/architecture): general flow overview.
- [Backend](sell/providers-backend): Details on the main endpoints needed for the chosen operation, the payload, the signature, and your public/private key.
- [LiveApp](sell/providers-liveapp): Details about your LiveApp, such as the LiveApp URL, the Manifest, or the use of the Ledger Exchange Services Kit alongside the Wallet API.
- [Test & Submit](sell/providers-test-and-submit): Details on how to use the  Developer Mode and other tools (coming soon) to test your integration end-to-end, as well as how to submit it.
- [Code examples](sell/code-examples): Code examples for your application demonstrating how to generate and encode payloads using different programming languages.
