# STACKS\_TESTNET

Pre-configured `StacksNetwork` object for Stacks **testnet**. Uses the Hiro testnet API (`https://api.testnet.hiro.so`) as the default base URL.

***

### Usage

```ts
import { STACKS_TESTNET } from '@stacks/network';

console.log(STACKS_TESTNET.client.baseUrl);
// 'https://api.testnet.hiro.so'
```

Most `@stacks/transactions` functions accept a network string directly:

```ts
import { makeSTXTokenTransfer } from '@stacks/transactions';

const tx = await makeSTXTokenTransfer({
  // ...
  network: 'testnet', // equivalent to passing STACKS_TESTNET
});
```

#### Notes

* Addresses on testnet start with `ST` (single-sig) or `SN` (multi-sig).
* The `bootAddress` is `ST000000000000000000002AMW42H`.
* Magic bytes: `T2`.
