# SolMask

> Zero-knowledge privacy protocol on Solana. Send SOL, USDC, and USDT to fresh
> wallets without leaking the on-chain link from sender to recipient.
> Non-custodial, banlist-enforced via Cipherowl, multi-language (en, es, de,
> ru, zh). Two on-chain instructions (deposit, withdraw) anchored by a Groth16
> proof and a per-pool Merkle tree.
