# Built on LayerHop and grants

> List your wallet, app, bot or agent on layerhop.com/ecosystem with POST /v1/ecosystem. Submissions are reviewed by hand; logos are fetched once and served by LayerHop.

Source: https://docs.layerhop.com/guides/ecosystem

[layerhop.com/ecosystem](https://layerhop.com/ecosystem) shows projects that swap or bridge with LayerHop's API, SDKs, widget, checkout or MCP server, grouped by category (wallets, apps, bots, AI agents, payments, developer tools, analytics). Submit yours with the form on that page or the API. Every submission is reviewed by hand before it is listed.

## How do I submit a project?

```bash
curl -X POST https://api.layerhop.com/v1/ecosystem \
  -H "content-type: application/json" \
  -d '{
    "name": "Hop Wallet",
    "tagline": "A wallet that swaps across chains with LayerHop",
    "category": "wallet",
    "uses": ["sdk", "widget"],
    "url": "https://hopwallet.example",
    "logoUrl": "https://hopwallet.example/logo.png",
    "twitter": "hopwallet",
    "contact": "dev@hopwallet.example"
  }'
```

The answer is `201` with `{ "entry": { "id": "eco_…", "status": "pending" } }`.

- `category`: `wallet`, `dapp`, `bot`, `agent`, `payments`, `tooling`, `analytics` or `other`. `uses`: one or more of `api`, `sdk`, `widget`, `checkout`, `mcp`, `telegram`, `other`.
- `name` (60 characters) and `tagline` (140) are one line of plain text; `url` must be https.
- `logoUrl` is optional. LayerHop downloads it once, at submission, and serves its own copy at `GET /v1/ecosystem/{id}/logo`. It must be https on the default port, on a public host, without redirects, at most 512 KB, and a PNG, JPEG, WebP or GIF by its content (SVG is refused). Anything else is `INVALID_PARAMS` with the reason.
- `contact` is private: only the reviewer sees it.
- 5 submissions per network per hour.

`GET /v1/ecosystem` returns the approved entries.

## What about grants?

The page has a grants section: integration grants, developer tooling, and research and safety. Amounts and the budget aren't final yet and are marked as placeholders on the page; to apply, email the address shown there with what you're building, who uses it and what the grant would pay for.
