To test your integration with the WaaS 2.0 API, you can use Sepolia (ETH testnet) and Bitcoin testnet environments. This guide explains how to obtain testnet coins from reliable sources.

## Sepolia testnet (SETH)

Use Sepolia testnet for testing Ethereum-based transactions. Monitor your transactions using:

* **Explorer**: [Etherscan](https://sepolia.etherscan.io/)

### Obtain SETH from faucets

Get SETH from these reliable faucet services:

* [QuickNode Sepolia Faucet](https://faucet.quicknode.com/drip)
* [Alchemy Sepolia Faucet](https://sepoliafaucet.com/)
* [Grabteeth](https://grabteeth.xyz/)
* [PoW Faucet](https://sepolia-faucet.pk910.de/)

## Bitcoin testnet (XTN)

Use Bitcoin testnet for testing BTC transactions. Monitor your transactions using:

* **Explorer**: [BlockCypher](https://live.blockcypher.com/btc-testnet/)

### Obtain XTN from faucets

Get XTN from these reliable faucet services:

* [Bitaps Bitcoin Testnet Faucet](https://tbtc.bitaps.com/)
* [Bitcoin Testnet Faucet](https://bitcoinfaucet.uo1.net/)
* [Coinfaucet](https://coinfaucet.eu/en/btc-testnet/)
* [Cryptopump](https://cryptopump.info/)

## Best practices

* Keep your testnet addresses separate from production addresses
* Request only the amount you need for testing
* Release unused testnet coins back to faucets when possible
