Hello hackers, zkSync welcomes developers to explore use cases by bringing solutions with the following zkSync features. We want you to have the freedom to work on what’s meaningful for you and to bring you closer to your target group of users with the zkSync tech.

Validiums Research on zkSync → $6,000 in Prizes

Build a dApp on zkSync that, when also deployed to a Validium, would take full advantage of the benefits that Validiums have to offer.

The two main benefits of building a Validium dApp are:

  1. Storage costs are drastically reduced, and you can use a lot of storage (because of the data availability and computation being done off-chain). Assume that storage write costs are negligible!
  2. Transaction data and smart contract data can be private (because with Validiums, the data is not published on L1) Assume the Validium is fully running on your local PC while still maintaining L1 security.

<aside> 📌 We require that the dApp proves that it will benefit from being deployed to a Validium on zkStack.



Best Wallets & Smart Accounts on zkSync → $7,000 in Prizes

With wallets and smart accounts, you can develop and showcase a wallet that takes full advantage of zkSync's account abstraction native implementation.

Examples: This could mean creating a wallet with novel recovery methods, advanced access controls, enhanced privacy measures, account inheritance, or automated features. For example, a wallet might use social recovery methods (trusted friends and family) instead of a seed phrase.

Or, a wallet could automate or group certain types of transactions, such as yield harvesting in DeFi, or include privacy features like optional transaction obfuscation.
