# Add Wallets to a Business Account

> Link an existing embedded wallet to a business account in Swift, and remove it again.

> [!NOTE]
>
> Business Accounts are in **early access**. See [Business Accounts](https://docs.dynamic.xyz/docs/business-accounts/accounts.md) for the model.

The Swift SDK links an embedded wallet you already own into a business account, so the team can share it. The account then owns the wallet (not a single user), and you become its first [signer](https://docs.dynamic.xyz/docs/swift/business-accounts/manage-signers.md).

## Find the wallet ID

Linking takes a wallet ID. Read it from the user's wallets, which are created automatically after authentication (see [wallet creation](https://docs.dynamic.xyz/docs/swift/wallet-creation.md)).

```swift theme={"system"}
import DynamicSDKSwift

let sdk = DynamicSDK.instance()

guard let wallet = sdk.wallets.userWallets.first, let walletId = wallet.id else { return }
```

## Link a wallet

`addWallet` links the wallet into the account, and returns the updated `BusinessAccountDetail` including members, signers, and wallets.

```swift theme={"system"}
let detail = try await sdk.businessAccounts.addWallet(
    businessAccountId: account.id,
    walletId: walletId
)

print(detail.wallets?.count ?? 0)
```

**walletId** `String` *required*

The wallet to link, from `sdk.wallets.userWallets`.

**businessAccountId** `String?`

The account to link into. If omitted, the wallet is linked into its per-wallet business account, which is found or created automatically. Pass it explicitly to link into a specific account you own or administer.

> [!WARNING]
>
> Only the wallet's owner can link it, and a wallet can belong to **one** business account. Linking a wallet that already belongs to a different account is rejected.

## Remove a wallet

`removeWallet` unlinks a wallet from the account and returns the updated account.

```swift theme={"system"}
let detail = try await sdk.businessAccounts.removeWallet(
    businessAccountId: account.id,
    walletId: walletId
)
```

## On error

Both calls are `async throws`. Catch the error and show it to the user, for example when the caller is not an owner or admin of the account:

```swift theme={"system"}
do {
    _ = try await sdk.businessAccounts.addWallet(businessAccountId: account.id, walletId: walletId)
} catch {
    print("Failed to link wallet: \(error)")
}
```
