# Cross-chain Data Protocol

**Eywa Cross-chain Data Protocol (CDP)** is the decentralized protocol for transferring data among different blockchains. It is the transport layer for all **Eywa** ecosystem products. The protocol is open-source and any developers can use the **Eywa Cross-chain Protocol** to implement cross-chain logic for their projects. This will allow teams to focus on developing the business logic of their dApps without being distracted by interoperability issues.
