Concept

ZENO Mixer is the first fully on-chain, Solana-native privacy mixer using a hybrid of zk-STARKs (for post-quantum resistance) and optimized CoinJoin (for low fees). Designed to exploit Solana’s speed while preserving anonymity, it’s the only mixer with:

ZENO Pools: Dynamic, auto-rebalancing SOL/SPL pools (1 SOL, 5 SOL, 10 SOL, 50 SOL)

Zero-Knowledge Light Clients: Proof generation in <500ms (thanks to Solana’s Sealevel runtime)

Stealth Addresses by Default: No need for manual note management (unlike Ethereum mixers)

MEV-Proof: Uses Solana’s priority fee system to prevent frontrunning
