Privacy on public blockchains is not a luxury, it is what makes permissionless finance usable. If every trade and transfer exposes your balance and behavior, transparency turns into spying.
Yona is a Solana based protocol for private DeFi powered by zero knowledge proofs. It enables confidential deposits, swaps (including cross-chain), and withdrawals of SOL and SPL tokens, while remaining fully verifiable on-chain.
Under the hood, Yona uses a sparse Merkle tree for UTXO commitments and Groth16 proofs to guarantee transaction validity without revealing sender, receiver or amounts.
Users can shield tokens into a private pool, move value through private transfers, perform anonymous swaps via Jupiter integration, swap cross-chain through Near Intents and withdraw to any address, breaking direct on chain links between their actions.
