# Stellar

Stellar supports the following signature `kinds`:

* `Transaction`, unsigned transaction.

## Transaction

Signs an unsigned transaction. Note: Stellar signing needs a network dependent [passphrase](https://developers.stellar.org/docs/learn/encyclopedia/network-configuration/network-passphrases). Therefore it's tied to a specific `network` rather than the blockchain kind.

### Typescript Example with Stellar SDK <a href="#typescript-example" id="typescript-example"></a>

First install the Stellar SDK. You can find the full documentation here: <https://stellar.github.io/js-stellar-sdk/>

Here a code sample to generate a signature via [the Dfns TypeScript SDK](https://github.com/dfns/dfns-sdk-ts):

```typescript
import { Asset, BASE_FEE, Horizon, Networks, Operation, TransactionBuilder } from '@stellar/stellar-sdk'

const walletId = 'wa-6lbfv-9esgj-xxxxxxxxxxxxxxxx'
const wallet = await dfnsClient.wallets.getWallet({ walletId })

const provider = new Horizon.Server(process.env.HORIZON_API_URL!)

const account = await provider.loadAccount(senderWallet.address)
const transaction = new TransactionBuilder(account, {
  fee: BASE_FEE,
  networkPassphrase: Networks.TESTNET,
})
  .addOperation(
    Operation.payment({
      destination: 'GAZWLHTNAOJWW52GZCUJAS5MSXK7LAWCUC5TFOFFVDQ7CDTNFODJ37GB',
      asset: Asset.native(),
      amount: '1',
    })
  )
  .setTimeout(180)
  .build()

const res = await dfnsClient.wallets.generateSignature({
  walletId,
  body: {
    kind: 'Transaction',
    transaction: `0x${transaction.toEnvelope().toXDR('hex')}`,
  },
})
```
