# Bridging

GIWA is an Ethereum-connected Layer 2, but it runs as a separate blockchain. To transfer assets (ETH, ERC-20 tokens) or data between these networks, a special process called **bridging** is required.

In simple terms, bridging lets you move your assets from Ethereum to GIWA — and back from GIWA to Ethereum.

Want to build apps that leverage bridging? Get started with the documentation below.
