# Issuer Wallet

Your issuer wallet holds the keys that control your token. Create one to get started, or restore an existing wallet with your mnemonic.

## Create a Wallet

```typescript theme={null}
import { IssuerSparkWallet } from "@buildonspark/issuer-sdk";

const { wallet, mnemonic } = await IssuerSparkWallet.initialize({
  options: { network: "REGTEST" }
});

console.log("Backup this phrase:", mnemonic);
console.log("Your address:", await wallet.getSparkAddress());
```

Store the mnemonic securely. It's the only way to recover your wallet.

## Restore a Wallet

```typescript theme={null}
const { wallet } = await IssuerSparkWallet.initialize({
  mnemonicOrSeed: "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about",
  options: { network: "MAINNET" }
});
```

## Networks

| Network   | Use                     |
| :-------- | :---------------------- |
| `REGTEST` | Development and testing |
| `MAINNET` | Production              |

Start on `REGTEST`. When you're ready for production, generate a fresh wallet on `MAINNET`.

## Multiple Tokens

An issuer identity can create multiple tokens. Use `getIssuerTokenIdentifiers()` and `getIssuerTokenBalances()` to work with all of them.

If you want separate issuer identities (separate keys) from the same mnemonic, derive them with different account numbers:

```typescript theme={null}
const { wallet: tokenA } = await IssuerSparkWallet.initialize({
  mnemonicOrSeed: "your mnemonic...",
  accountNumber: 0,
  options: { network: "REGTEST" }
});

const { wallet: tokenB } = await IssuerSparkWallet.initialize({
  mnemonicOrSeed: "your mnemonic...",
  accountNumber: 1,
  options: { network: "REGTEST" }
});
```

## Cleanup

Close connections when your app shuts down:

```typescript theme={null}
await wallet.cleanupConnections();
```
