What Can You Build?

Using the new primitive, xcall, developers can send assets and any arbitrary data across chains. This means you can build with crosschain interoperability out of the box, allowing your smart contracts to directly interact with other protocols across chains! You’ll find there is a whole realm of new possibilities using features enabled by the protocol, like JS-style callbacks.

xcall allows for a new class of crosschain use cases, such as:

🔗 Crosschain DAO governance

💧 Crosschain liquidity management

💎 Crosschain NFTs

🔮 And many more that have yet to be discovered
