# Get testnet STX

Get free testnet STX for testing apps, from the Stacks Explorer sandbox faucet.

Testnet STX has no value. Developers use it to test apps on the Stacks testnet.

## Request testnet STX

1. Switch Leather to a test network: click the settings icon in the header, select "Settings", then "Network", and choose "Testnet4". "Testnet3" and "Signet" use the same Stacks testnet. See [Change Network](/settings-and-customization/change-network.md).
2. Open the [Stacks Explorer sandbox faucet](https://explorer.hiro.so/sandbox/faucet?chain=testnet).
3. Click "Connect Stacks Wallet" and choose Leather.
4. Click "Request STX".

The STX arrives at the Stacks address of your Leather account on testnet.
