Confidential Token Distributions & Payroll

Showcase Project — This is a demonstration project by Trion Labs showcasing our expertise in Zero-Knowledge systems and protocol design. For production implementations or collaborations, contact us.

Overview

Distribute tokens to emails with ZK proofs. No wallet exposure. No identity leaks.

Zarf Protocol is a privacy-first payment and token distribution protocol that enables users to send funds or create vestings to an email address instead of a wallet address. By utilizing zero-knowledge proofs, we decouple identity from on-chain addresses, allowing for secure, anonymous, and programmable payments.

Features

🔒 Privacy Powered with ZK

Distribute tokens without exposing recipient identities on-chain. Zarf uses advanced zero-knowledge circuits (Noir) to verify email ownership without ever revealing the email address or the link to the claiming wallet.

⚡ E-mail First Claiming

No wallet needed to start. Recipients receive funds via an email link and can claim them using a standard Google login. This dramatically lowers the barrier to entry for non-crypto natives.

⏳ On-chain & Programmable

Configure cliff periods, linear release schedules, and complex vesting terms directly in smart contracts. Zarf is not just for one-time payments; it's a robust infrastructure for payroll, grants, and token streaming.

Architecture

1. Off-chain ZK Proof Generation: Users generate proofs of email ownership locally in the browser or via a secure relayer.
2. Smart Contracts (EVM):
   • Registry: Manages trusted DKIM keys and verifiers.
   • Escrow: Holds funds securely until a valid proof is submitted.
   • Verifier: On-chain Groth16 verifier (generated via Noir) validates the ZK proof.
3. Frontend: A seamless Svelte-based interface for sending and claiming.

Tech Stack
