Kaan hosts Yaman and Dennis from Trion Labs to introduce ZARF: a zero-knowledge protocol that lets users receive tokens via email addresses and claim them with Google login, keeping wallet identity private. The project exemplifies new use cases enabled by Stellar's X-Ray protocol upgrade.
The Stellar Developers Meeting features Trion Labs introducing ZARF, a privacy-first token distribution protocol that separates email-based receiving from wallet identity disclosure. Using zero-knowledge proofs, ZARF allows users to claim tokens sent to their email addresses via standard Google login, with no on-chain record linking recipient to wallet address. This application emerges from Stellar's X-Ray protocol upgrade, which introduced native zero-knowledge verification primitives at the protocol layer. The discussion also covers OpenZeppelin's confidential tokens, launched the same day, which obfuscate transaction amounts and balances. Together, the two innovations address distinct privacy gaps: ZARF hides recipient identity, while confidential tokens hide transfer amounts. Both exemplify how protocol-level ZK support enables new applications.
