# Faucet

Faucet is a developer tool designed to acquire free test tokens for development on different testnets. As a Bitcoin Layer 2 and an EVM-compatible one, SatoshiVM uses BTC as the native gas token that needs to be acquired on the Bitcoin chain and then transferred to Layer 2 for use via cross-chain methods.
