Builders may work individually or within a team of up to three. # Hackathon Schedule - **Start Date:** July 15 - **End Date:** August 19 - **Office Hours:** - July 17, from 11:30am GMT to 12:30pm GMT (6:30am ET to 7:30am ET) - July 22, from 1pm GMT to 2pm GMT (8am ET to 9am ET) - July 24, from 1pm GMT to 2pm GMT (8am ET to 10am ET) - July 26, from 3pm GMT to 4pm GMT (10am ET to 11am ET) - Additional Office Hours Added!! - Aug 6, from 1pm GMT to 2pm GMT (8am ET to 9am ET) - Aug 8, from 1pm GMT to 2pm GMT (8am ET to 9am ET) - Aug 13, from 1pm GMT to 2pm GMT (8am ET to 9am ET) - Aug 15, from 1pm GMT to 2pm GMT (8am ET to 9am ET) # Prize Pool - **First Prize:** $15,000 USD - **Second Prize:** $10,000 USD - **Third Prize:** $5,000 USD # Documentation, Support, and Contact Information - Documentation is available at [Zenrock Labs Documentation](https://docs.zenrocklabs.io/) - For questions related to the hackathon and support, join our Discord channel at [Zenrock Labs Discord](https://discord.com/channels/1226844560181952594/1258159292058701938) # Suggested Quests ## Minting and Wrapping Tokens - From zrSign on Amoy, mint zrETH on Blast. - Mint zrETH on Blast using a Layerzero oApp. - Build a wrapped token service to enable wrapped Pepe on Osmosis. ## User Interface Development - Build a zrSign UI for retail users. - Build a Portfolio View in the Zenrock chain user interface. ## Application Development - Build a Layerzero oApp to interact with zrSign. - Build a decentralized finance platform that allows users to lend, borrow, and earn interest on assets across multiple blockchains. Utilize zrSign for managing cross-chain transactions and ensure efficient and secure asset transfer across chains. - Build a platform that aggregates liquidity from various decentralized exchanges (DEXs) on different blockchains. ## Cross-Chain and Interoperability - Build a token bridge that allows seamless transfer of tokens between different blockchains using zrSign and its underlying MPC tech instead of a multi-sig. - Build a cross-chain collateral AVS with a bridge contract deployed through zrSign. - Leveraging the above concept, apply the design to cross-ecosystem transactions such as EVM to Cosmos or Bitcoin. ## Wallet and Key Management - Build one or more wallet integrations to supply unsigned transactions to Zenrock. - Build an identity abstraction service that lets users add public keys to a workspace and allow for key rotation, similar to a DID standard. - Build a custom keyring which can be any permissionless protocol or a permissioned solution with a public sandbox. ## CosmWasm Implementation - Build a CosmWasm implementation of zrSign. ## Bugs - Rewards will be considered for bugs found during the hackathon with an emphasis on those related to security # Why Participate? Developers competing in this hackathon will have the unique opportunity to work closely with our team and cross-chain technology stack. We will onboard developers and integrate innovative solutions into our ecosystem. This is your chance to make a significant impact in the blockchain space, gain recognition, and win substantial prizes. # Judging Criteria and Weighting - **Innovation and Creativity (25%)** - Originality of the idea - Creativity in problem-solving - **Technical Difficulty (25%)** - Complexity of the technology used - Quality of the implementation - **Functionality and Usability (20%)** - Completeness of the prototype - User interface and user experience (where applicable) - **Impact and Feasibility (20%)** - Practicality and feasibility - Potential impact on the target audience or market - **Presentation and Documentation (10%)** - Quality of documentation provided # Judges Panel - Jason Losh, CTO @ Zenrock Labs - Martin Schaffner, Lead Blockchain Architect @ Zenrock Labs - Chris Morris, Chief Blockchain Engineer @ Zenrock Labs - Venimir Petkov, Lead Smart Contract Engineer @ Zenrock Labs - Matt Krak, Developer Ecosystem Lead @ LayerZero Labs # Prize Distribution Winners and prize distribution will occur the week of August 5th.
