Zephyr Protocol is a stablecoin system that integrates over-collateralization mechanisms with privacy features derived from Monero architecture. The protocol issues four native assets: ZEPH, a reserve coin; ZSD, a stablecoin pegged to USD; ZRS, equity shares in the reserve; and ZYS, shares that accrue yield from staked ZSD. The system combines the Djed stablecoin model with on-chain privacy and transaction untraceability. Core functionality relies on algorithmic over-collateralization to maintain stability while preserving transaction confidentiality. The protocol operates as a decentralized, community-governed system without a centralized corporate entity. ZEPH trades on centralized exchanges including MEXC.

Core components include key abstraction for simplified credential management, gas abstraction to eliminate native token requirements for transaction fees, transaction abstraction for flexible execution models, chain abstraction for multi-chain interactions, and smart routing addresses for optimized account addressing. The system functions as developer tooling and infrastructure rather than a consumer-facing wallet or protocol, allowing application builders to reduce user friction by removing the need for private key management or gas token holdings. ZeroDev is developed by Offchain Labs.

Zero Knowledge FM operates the Zero Knowledge Podcast, a long-running audio and video show focused on zero-knowledge proof research, cryptography, distributed systems, and the decentralized web. The podcast covers technical topics including ZK proof systems, formal verification, privacy protocols, and open-source tooling, targeting researchers, developers, and protocol engineers working in the ZK and broader Web3 space. Beyond the podcast, the organization runs zkSummit, a recurring in-person conference series for the ZK research community, a jobs board for ZK-focused roles, and ZK Hack, a learning and hackathon platform. The project is community-supported via Patreon and crypto donations, with no single corporate HQ publicly disclosed.
