ArbiLoop is an Arbitrum-native DeFi app for lending, borrowing, and loop strategies.It is non-custodial, automation-first, and focused on safer, more efficient DeFi management.
Instead of turning the blockchain into a fully opaque privacy layer (which undermines the transparency that made blockchains valuable in the first place), we built StealthPay—an opt-in privacy primitive for users who don’t want their on-chain activity easily trackable, while still preserving the public verifiability of transactions. StealthPay is built on ERC-5564 (Stealth Addresses) and ERC-6538 (Stealth Meta-Address Registry), using the stealth “announcer” flow to enable users to send and receive funds on-chain via one-time stealth addresses rather than their public wallet address. For this hackathon, we shipped an MVP focused on core stealth transfers. Post-hackathon, we plan to expand with features like P2P flows, ENS-based routing (we hit an ENS resolver issue on Arbitrum during implementation, which we also want to support as a first-class feature), a message/inbox experience, and other privacy-forward UX improvements.
