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
