# Providers

> React Native context providers for React Native SDK reference for Crossmint wallets

<Warning>
  **You are viewing docs for the previous version of the Wallets SDK.** We recommend upgrading to V1.
  See the [updated version of this page](/sdk-reference/wallets/react-native/providers) or the [V1 migration guide](/wallets/guides/migrate-to-v1).
</Warning>

1. `CrossmintProvider` — SDK initialization (required for all Crossmint features)
2. `CrossmintWalletProvider` — Wallet creation and management

***

## CrossmintProvider

Root provider for the Crossmint SDK. Must wrap your entire application. Initializes the SDK with your API key and sets up logging.

### Props

<ResponseField name="apiKey" type="string" required>
  Your Crossmint client-side API key.
</ResponseField>

<ResponseField name="consoleLogLevel" type="ConsoleLogLevel">
  Minimum log level for console output (or "silent" to suppress all output). Logs below this level will not be written to the console. Set to "silent" to completely suppress console output. Defaults to "debug" (all logs shown) for backward compatibility.
</ResponseField>

<ResponseField name="overrideBaseUrl" type="string">
  Override the base API URL.
</ResponseField>

### Usage

```tsx theme={null}
import { CrossmintProvider } from "@crossmint/client-sdk-react-native-ui";

function App() {
    return (
        <CrossmintProvider apiKey="YOUR_CLIENT_API_KEY">
            {/* Your app content */}
        </CrossmintProvider>
    );
}
```

***

## CrossmintWalletProvider

Provider for wallet creation and management. Must be nested inside CrossmintProvider. Handles secure communication with the Crossmint signer via a hidden WebView.

### Props

<ResponseField name="appearance" type="UIConfig">
  Optional appearance configuration for styling built-in UI components.
</ResponseField>

<ResponseField name="callbacks" type="{ onTransactionStart?: () => Promise<void>; onWalletCreationStart?: () => Promise<void> }">
  Optional lifecycle callbacks invoked during wallet creation and transaction signing.
</ResponseField>

<ResponseField name="createOnLogin" type="CreateOnLogin">
  Wallet configuration for automatic creation on user login. Defines the chain and signer type for the wallet.

  <Expandable title="properties">
    <ResponseField name="chain" type="Chain" required>
      The blockchain to create the wallet on (e.g. "base-sepolia").
    </ResponseField>

    <ResponseField name="signer" type="SignerConfigForChain" required>
      The signer configuration (e.g. `{ type: "email" }`).
    </ResponseField>

    <ResponseField name="owner" type="string">
      Optional owner identifier.
    </ResponseField>

    <ResponseField name="alias" type="string">
      Optional wallet alias.
    </ResponseField>

    <ResponseField name="plugins" type="WalletPlugin[]">
      Optional array of wallet plugins.

    <ResponseField name="delegatedSigners" type="DelegatedSigner[]">
      Optional array of delegated signers.
    </ResponseField>
  </Expandable>
</ResponseField>

<ResponseField name="headlessSigningFlow" type="boolean">
  When true (default), no UI is rendered and signing flows must be handled manually. When false, built-in UI components are rendered.
</ResponseField>

### Usage

```tsx theme={null}
import {
    CrossmintProvider,
    CrossmintWalletProvider,
} from "@crossmint/client-sdk-react-native-ui";

function App() {
    return (
        <CrossmintProvider apiKey="YOUR_CLIENT_API_KEY">
            <CrossmintWalletProvider
                createOnLogin={{
                    chain: "base-sepolia",
                    signer: { type: "email" },
                }}
            >
                {/* Your app content */}
            </CrossmintWalletProvider>
        </CrossmintProvider>
