## What it does

This skill guides an agent through wallet setup with Mobile Wallet Adapter and `@wallet-ui/react-native-kit`: mounting the provider, using `useMobileWallet`, displaying an account address, and connecting or disconnecting. It also covers chain data, message signatures, and transaction sending. For apps already using `@wallet-ui/react-native-web3js`, the skill points to a separate path. Check `package.json` first; mixing the two client stacks can leave provider props and transaction code incompatible.

Android needs a development build for Mobile Wallet Adapter; Expo Go does not work. Place `QueryClientProvider` from `@tanstack/react-query` above the wallet provider. Include `chain` in React Query keys for network data, or a cluster switch can show cached results from the previous network. Wallet-picker cancellation rejects the `connect()` promise, so the skill advises catching that outcome rather than treating it as a crash.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add solana-mobile/solana-mobile-skills --skill solana-mobile-wallet -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/solana-mobile-wallet/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/solana-mobile-wallet/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add solana-mobile/solana-mobile-skills --skill solana-mobile-wallet -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/solana-mobile-wallet/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add solana-mobile/solana-mobile-skills --skill solana-mobile-wallet -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/solana-mobile-wallet/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install solana-mobile/solana-mobile-skills solana-mobile-wallet
```

2. **Manually: put the files in place**
- File: `.github/skills/solana-mobile-wallet/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add solana-mobile/solana-mobile-skills --skill solana-mobile-wallet -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/solana-mobile/solana-mobile-skills --path skills/solana-mobile-wallet
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/solana-mobile-wallet/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add solana-mobile/solana-mobile-skills --skill solana-mobile-wallet -a opencode
```

### Claude.ai

**Claude.ai**

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/solana-mobile/solana-mobile-skills/tree/HEAD/skills/solana-mobile-wallet/SKILL.md

## When to use it
- add connect and disconnect controls for a Solana wallet
- display the address of the authorized account
- sign a message or implement sign-in with Solana
- send a transaction or transfer SOL
- fetch an account balance through the wallet client

## Example prompts
- Add a Solana wallet connect button to my Expo app using Mobile Wallet Adapter.
- Check `package.json` and set up the wallet with the client stack this project already uses.
- Add a SOL transfer with `useMobileWallet` and handle wallet-picker cancellation.

# Solana wallets on mobile

Wallet connection and transaction signing through Mobile Wallet Adapter (MWA), wrapped by
`@wallet-ui/react-native-kit` (or `@wallet-ui/react-native-web3js` on the legacy stack).

**MWA requires a development build on Android. Expo Go will not work.** If the project has
no development build yet, or does not exist, start with the `solana-mobile` skill.

## Step 1: pick the stack — do this before writing any code

**Write kit code.** `@solana/kit` with `@wallet-ui/react-native-kit` is the stack to reach for,
and everything in this file describes it.

There is exactly one reason to write `@solana/web3.js` instead: the project already runs on it.
Check `package.json` first.

| `package.json` says | Do this |
| --- | --- |
| `@wallet-ui/react-native-kit`, or no Solana client yet | Kit. This file, plus [references/kit.md](references/kit.md) |
| `@wallet-ui/react-native-web3js` is the app's Solana client | [references/web3js.md](references/web3js.md) |
| The user explicitly asked for web3.js | [references/web3js.md](references/web3js.md), and say why kit would be better |

Do not introduce web3.js into a kit project, or mix the two in one app. Their provider props,
hook return values, and transaction construction all differ, so code from one silently fails on
the other. If a project has no Solana client at all, that is a new build — use kit.

Adding a *new* wallet feature to an existing web3.js app is not a reason to migrate mid-task.
Match what is there, and mention migration as a follow-up if it seems worth it.

## Step 2: confirm the provider is mounted

`useMobileWallet` returns empty state without `MobileWalletProvider` above it. Look for it in
the root layout or an app-providers module.

Build the cluster with the `createSolana*` helpers rather than by hand — a `SolanaCluster` also
needs a `label`, which the helpers fill in:

```tsx
import {
  type AppIdentity,
  createSolanaDevnet,
  MobileWalletProvider,
  type SolanaCluster,
} from '@wallet-ui/react-native-kit'

const identity: AppIdentity = { name: 'My App' }
const cluster: SolanaCluster = createSolanaDevnet({ url: 'https://api.devnet.solana.com' })
````
