About
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.Connext is a modular interoperability protocol that lets you build secure crosschain dApps (xApps).

Prizes
🏆 $1000 - Best cross-chain interaction using xcall
Use Connext's xcall through the SDK or direct contract calls in your project to build new, exciting cross-chain use cases.
🚀 $1000 - Best demonstration of chain abstracted user experience
Build an application that demonstrates exceptional user experience for cross-chain interactions.
🥇🥈🥉 $1500, $1000, $500 - Top 3 projects that deploy and use an xERC20
Deploy an xERC20 and use it in your project. Bonus points for complexity and creativity. If you use an existing ERC20 and migrate it to an xERC20, this counts toward complexity.

Getting Started
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.
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
Chain Abstraction
The goal of chain abstraction is to free the user from chain management. Connext enables dApps to build toward this kind of ideal user experience. [Read more](https://docs.connext.network/usecases/chain-abstraction) about chain abstraction and how to build chain-abstracted dApps.
xERC20 Token Standard
Also known as [ERC-7281: Sovereign Bridged Tokens](https://ethereum-magicians.org/t/erc-7281-sovereign-bridged-tokens/14979/1), the xERC20 open token standard is an extension of ERC20 that allows tokens to be transferred across chains with zero slippage, enables fungibility between bridges, and allows token issuers to set custom rate limits for every bridge. [Read more](https://docs.connext.network/usecases/xerc20) about xERC20s and how to deploy them.
