## Rockswap Cross-chain Interoperability

In partnership with deBridge Finance, Rockswap also supports direct cross-chain transactions of assets between 10+ chains including the Bitrock chain, enhancing accessibility and interaction between various ecosystems. This is made possible in part by the deBridge Liquidity Network (DLN) protocol, which is a high-performance cross-chain value transfer infrastructure built by deBridge with a 0-TVL design (no liquidity pools). Learn more about the DLN protocol [here](https://docs.debridge.finance/dln-the-debridge-liquidity-network-protocol/introduction).

Gas fees are equalized and paid in the origin chain's native (gas) token. For example, if the swap is performed from the BROCK chain to another chain, gas fees would be payable in native Bitrock, and are deducted from the user's wallet then deposited into the protocol treasury on the Bitrock chain. Supported chains include Bitrock, ETH, BSC, SOL, Polygon, ARB, OP, and more!
