zkAster

zkAster is a cryptocurrency exchange and settlement layer founded to implement zero-knowledge technology for enhanced privacy. Initially starting as a fixed-rate swap platform, it plans to evolve into a comprehensive private payment system. The architecture emphasizes privacy with features such as no stored private keys, a backend that acts as a thin proxy to avoid user identity reconstruction, and retention of only minimal metadata.

The protocol aims to integrate advanced zero-knowledge mechanisms, including commitments, nullifiers, and stealth addresses, facilitating private transfers and anonymous transactions. zkAster targets various user groups, from those seeking low-fee swaps to privacy-focused users needing full anonymity. It also provides infrastructure for developers requiring auditable yet private payment systems. The roadmap outlines a transition from a basic swapping tool to a complete privacy settlement layer.
