# Fetch External Wallets to Connect
While this SDK is still supported, we recommend using newer [JavaScript SDK](/docs/javascript/reference/react-native-quickstart), which is optimized for React Native, but also comes with a host of other benefits.
This guide is for Using Your UI, as Dynamic UI components already display the wallets for you.
## Wallet keys (when you need them)
Some flows require a stable identifier for a wallet option/provider (for example passing a key into a “connect/link this wallet” call, or rendering a wallet icon). Depending on your SDK, you can get these keys in a few ways:
### 1) From wallet options/providers returned by the SDK
Use `walletOptions` from your client/hook and read `walletOptions[].key`.
### 2) From Wallet Book (for keys + metadata/icons)
The full wallet list is available from `https://dynamic-static-assets.com/wallet-book/v1/latest/wallet-book.json`.
Each wallet entry includes its `key`, `name`, and branding metadata (useful when rendering icons):
```
"argentx": {
"brand": {
"alt": "ArgentX",
"primaryColor": "#FF875B",
"spriteId": "argentx"
},
"key": "argentx",
"name": "ArgentX"
},
```
### 3) From the dashboard chain pages
Each chain page in the dashboard lists supported wallets and their keys (for example [EVM](https://app.dynamic.xyz/dashboard/chains-and-networks#evm) or [Solana](https://app.dynamic.xyz/dashboard/chains-and-networks#solana)).
