# Create a wallet

There are a number of ways to instantiate a wallet, depending on your needs.

Wallet classes are mostly stateless, so you can instantiate and throw them away as needed. Your app must therefore manage state, such as fetching and storing proofs in a database.

NB: You must always call `loadMint()` or `loadMintFromCache` after instantiating a wallet.

```typescript
import { Wallet } from '@cashu/cashu-ts';

// Simplest: With a mint URL
const mintUrl = 'http://localhost:3338';
const wallet1 = new Wallet(mintUrl); // unit is 'sat'
await wallet1.loadMint(); // wallet is now ready to use

// Persist these in your app
const keychainCache = wallet1.keyChain.cache; // KeyChainCache
const mintInfoCache = wallet1.getMintInfo().cache; // GetInfoResponse

// Advanced: With cached mint data (avoids network calls on startup)
const wallet2 = new Wallet(keychainCache.mintUrl, { unit: keychainCache.unit });
wallet2.loadMintFromCache(mintInfoCache, keychainCache);
// wallet2 is now ready to use
```
