Connext is a modular interoperability protocol that lets you build secure crosschain dApps (xApps). With Connext's recent network upgrade, it is now the most trust-minimized interoperability protocol available today for building powerful crosschain functionality with a developer-friendly interface.
🏆 Best Crosschain Applications - up to $3,000
Most innovative or useful xchain apps built on Connext.
🔗 Take an Existing Protocol Crosschain - up to $1,000
Augmenting an existing protocol with xchain functionality by integrating with Connext. Even if you aren’t the protocol owner, this can be used as an example for other integrators. More complex integrations with good documentation will score bonus points.
📩 Send and Receive Data with xcall - pooled $1,000
Deploy a contract that calls xcall and a contract that implements `IXReceiver to receive the data. A successful cross-chain call makes you eligible to share this pool reward!
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
