# Claim Handle Form

> A sign-up step for picking a handle, built from Username Field. A live profile card previews the avatar initial and the profile address as you type, availability is checked while you pause with stale lookups cancelled, taken names offer one-tap suggestions, and Continue only unlocks once the handle is confirmed free.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/claim-handle-form/claim-handle-form.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/claim-handle-form
```
