Sygma is the interoperability layer for building cross-chain applications. With Sygma, developers can leverage secure and efficient multi-bridge infrastructure to extend their applications beyond a single blockchain. 

Next-generation composability and interoperability will provide applications with the features they need, such as being able to swap LP pairs across different networks. 

Whichever solution projects have in mind, Sygma gives you the power to easily deploy the multi-chain infrastructure that lowers the barrier of entry for both developers and users and makes the decentralized web a reality.

🏆 Prizes:

  • 🥇We will award $2000 USD to the top project that uses both Generic Message Passing (GMP) and the Sygma-SDK.

🥈We will award $1000 USD to each of the top 2 submissions that use the Sygma-SDK for bridging ERC721 and/or ERC20 assets.

💰Prize Description:

Sygma is a cross-chain bridge specializing in Generic Message Passing (GMP) as well as ERC20 and ERC721 transfers. With the Sygma-SDK, developers can incorporate cross-chain capabilities within their applications without needing to manage the additional infrastructural overhead or security concerns that accompany highly sophisticated bridging systems.

The Sygma team wants to see what interesting cross-chain functionality YOU are able to incorporate with the Sygma-SDK.

Prizes will be rewarded to the projects that showcase the most well-designed and thought-inspiring use case for Sygma.

⚠️ Requirements:

  • Your project must use the Sygma-SDK
  • Your project must incorporate one of the following testnets:
  • Goerli (Ethereum)
  • Mumbai (Polygon)
  • Moonbase Alpha (Ethereum)
  • Open source is preferred but not required. Code must be visible during judging
  • Your project description must mention how you used the Sygma-SDK and where in the codebase this usage can be seen
  • Your project must have a live, deployed, public, interactive demo that can be used by judges and other hackathon participants
  • Your project must include a video presentation of the demo and an explanation of the technology behind it


This workshop is happening in-person
Sygma 🛠 An SDK for Interoperable Apps
Time: 05:00 PM -05 – Oct 7, 2022
Location: Workshop Room 2

Getting Started

🛠 Resources:

🌈For Inspiration:

  • Use GMP to collateralize an ERC721 token on one network and receive a loan on another
  • Move liquidity pairs (e.g. Uniswap, SushiSwap, etc.) from one network to another in order to achieve better APY
  • Create a blockchain-enabled game that uses ERC20 or ERC721 token transfers between different chains
  • Use GMP to explore cross-chain governance

🎨 Judging Criteria:

  • Use of Sygma-SDK
  • Cross-chain functionality demonstrated
  • Define a real-world problem with Sygma as the solution
  • Creativity
  • Code quality and documentation
  • Clean and intuitive UI/UX
