# Web3Auth v10 external wallet adapters migration guide

This guide focuses specifically on migrating external wallet adapter configurations from Web3Auth v8
to v10. This is a supplementary guide to the main
[v8 to v10 migration guide](README.mdx).

## Overview

In v8, external wallets required manual adapter configuration. V10 simplifies this by using MIPD
(Multiple Injected provider Discovery) to automatically detect and provide access to external
wallets without manual setup.

## Migration steps

### External wallet adapter migration

```typescript
// remove-start
// Individual wallet adapters

// Default adapter functions

// Manual adapter configuration
const metamaskAdapter = new MetamaskAdapter()
const phantomAdapter = new PhantomAdapter()
web3auth.configureAdapter(metamaskAdapter)
web3auth.configureAdapter(phantomAdapter)

// Or using helper functions
const adapters = await getDefaultExternalAdapters({ options: web3AuthOptions })
adapters.forEach(adapter => {
  web3auth.configureAdapter(adapter)
})

await web3auth.initModal()
// remove-end

// add-start
// All external wallets are automatically detected via MIPD
// No manual adapter configuration needed
await web3auth.init()
// add-end
```

## Key changes

- **Package Removal:** Remove all external wallet adapter packages
- **MIPD Integration:** External wallets are automatically detected using MIPD (Multiple Injected
  provider Discovery)
- **No Configuration:** No need to manually configure or register external adapters
- **WalletConnect Support:** WalletConnect-compatible wallets are automatically available

## Package removal

Remove these deprecated packages from your project:

```bash npm2yarn
# Remove all external wallet adapter packages
npm uninstall @web3auth/metamask-adapter @web3auth/phantom-adapter @web3auth/solflare-adapter @web3auth/slope-adapter @web3auth/default-evm-adapter @web3auth/default-solana-adapter
```

## How it works in v10

V10 uses MIPD (Multiple Injected provider Discovery) to automatically detect injected wallets in the
browser. When users attempt to connect, they'll see:

1. **Installed wallets:** Any injected wallets found in the browser
2. **WalletConnect options:** Popular wallets available via WalletConnect
3. **Install prompts:** Options to install wallets if none are found

This provides a better user experience with no configuration required from developers.
