Stealth Keystore

With Stealth Keystore we set out to showcase that keystores will not only improve cross-chain smart account UX and security, but also enable much better privacy defaults on public EVM chains and give the full power of stealth addresses to smart accounts.

Users can:

• register their keys in our onchain keystore
• deploy an unlimited amount of smart accounts that are all controlled by these registered keys
• transact from these smart accounts privately, there is no public connection to the registered keys or to any of the other smart accounts controlled by the same user
• rotate their keys in the keystore and instantly control all of their stealth smart accounts with the new keys

Our submission was built using the following stack:

• ZK proofs using Noir
• Safe smart accounts
• Solidity contracts (keystore, smart account owner, zk verifier) deployed on Base
• Next.js frontend
