# Get Listed

Built something on Megapot? Get your app in front of Megapot players. This page covers three things: getting listed on megapot.io, tagging your purchases so your app shows up on results, and linking your users to the ecosystem page.

***

## 1. Get listed on megapot.io

Live apps can be featured on:

* The [Ecosystem page](https://megapot.io/ecosystem)
* The [Build page](https://megapot.io/build)
* The **Apps** tab on every drawing's results page

Listing is team-reviewed, not automatic. To apply, [contact the team](https://megapot.io/support) with:

* Your app's name and URL
* A one-line description of what it does
* A square logo (PNG)
* Your `_source` tag (see below)
* Your referrer wallet address

***

## 2. Set your `_source` tag so your app shows up on results

Every purchase method takes a trailing `bytes32 _source` argument. When your tag is on Megapot's allow-list, megapot.io shows your app's name and icon on tickets bought through your app, including on drawing results, and gives your app its own page at [megapot.io/sources](https://megapot.io/sources).

To show up properly:

1. **Pick one short tag for your app** (for example `myapp`) and encode it as `bytes32`:

   ```typescript
   import { stringToHex } from "viem";

   const SOURCE = stringToHex("myapp", { size: 32 });
   ```
2. **Pass the same tag on every purchase call**, across every method you use (`buyTickets`, random buys, batch orders, subscriptions, auto-compound). Each distinct tag counts as a separate source, so tickets bought under a different or mistyped tag will not show up under your app.
3. **Never leave it empty.** Tickets bought with an all-zero `_source` cannot be attributed to your app.
4. **Send us the exact tag** when you apply, so we can add it to the allow-list.

{% hint style="info" %}
`_source` is display and attribution only. It never moves money. You get paid through your referrer wallet in `_referrers`, so set both. See [Referrals & Attribution](/build-on-megapot/build/referrals-and-attribution.md).
{% endhint %}

## 3. Link your users to the Ecosystem page

Add a link to [megapot.io/ecosystem](https://megapot.io/ecosystem) from your app, for example in your footer, FAQ, or "How it works" section. It shows your users that your app runs on the Megapot protocol, with a live view of the shared prize pool and the other apps built on it.
