# ExternalSignerManager

> Manage G-address (delegated) signers via kit.externalSigners.

## Overview

`ExternalSignerManager` manages Stellar G-address signers - either raw keypairs or connected wallet extensions. Access it via `kit.externalSigners`.

```typescript theme={null}
// Add a keypair (in-memory only)
kit.externalSigners.addFromSecret('SXXX...');

// Connect an external wallet (e.g. Freighter)
await kit.externalSigners.addFromWallet(walletAdapter);
```

## Methods

### `addFromSecret()`

Add a Stellar keypair as an external signer. Stored in memory only - not persisted to storage.

```typescript theme={null}
kit.externalSigners.addFromSecret(secretKey: string);
```

<Warning>
  This method is primarily for testing and development. Never use it with real secret keys in production.
</Warning>

### `addFromWallet()`

Connect an external wallet (e.g. Freighter, Lobstr) as a signer.

```typescript theme={null}
await kit.externalSigners.addFromWallet(adapter: ExternalWalletAdapter);
```

See [Wallet Adapters](/advanced/wallet-adapters) for available adapters.

### `restoreConnections()`

Restore previously persisted wallet connections on page load.

```typescript theme={null}
await kit.externalSigners.restoreConnections();
```

### `canSignFor()`

Check if a signer is available for a given G-address.

```typescript theme={null}
const can = kit.externalSigners.canSignFor(address: string); // boolean
```

### `signAuthEntry()`

Sign a single auth entry using the signer for the given address.

```typescript theme={null}
const signed = await kit.externalSigners.signAuthEntry(
  address: string,
  authEntry: xdr.SorobanAuthorizationEntry
);
```

### `getAll()`

Return all registered external signers.

```typescript theme={null}
const signers = kit.externalSigners.getAll(); // ConnectedWallet[]
```

### `remove()`

Remove an external signer by address.

```typescript theme={null}
kit.externalSigners.remove(address: string);
```

## Types

```typescript theme={null}
import type { ExternalWalletAdapter, ConnectedWallet } from 'smart-account-kit';

interface ExternalWalletAdapter {
  getAddress(): Promise<string>;
  signAuthEntry(authEntry: xdr.SorobanAuthorizationEntry): Promise<xdr.SorobanAuthorizationEntry>;
  disconnect?(): Promise<void>;
}

interface ConnectedWallet {
  address: string;
  adapter: ExternalWalletAdapter;
}
```

## StellarWalletsKit Integration

The SDK ships with a `StellarWalletsKitAdapter` for first-class `@creit-tech/stellar-wallets-kit` support:

```typescript theme={null}
import { StellarWalletsKitAdapter } from 'smart-account-kit';

const adapter = new StellarWalletsKitAdapter({
  kit: stellarWalletsKit,
  onConnectionChange: (connected) => {
    console.log('External wallet:', connected ? 'connected' : 'disconnected');
  },
});

await kit.externalSigners.addFromWallet(adapter);
```

See [Wallet Adapters](/advanced/wallet-adapters) for the full guide.
