A privacy stack for Solana — shielded UTXO transfers and zero-knowledge proofs, with compliance-aware viewing keys.
Cloak is heading to prague next wednesday! 🇧🇷🇨🇿 We'll be talking about privacy on Solana, private payments and showing Cloak live. If you're around, come hang out with us! 👀
Born on the island 🏝️

Do you know the difference between anonymous, pseudonymous, and confidential? 👀 Because it’s probably your entire financial history. https://t.co/gNIsKbO0p5
Yesterday was less about building and more about the people doing it. Brazilian BBQ in Floripa with @norafinancexyz, @contavcbr and @SuperteamBR, showing the @islanddao crowd how we do things down here. Picanha, costela de chão, dunes and beach. Back to shipping tomorrow 🇧🇷🥩 Good to have @islanddao in Brazil. https://x.com/validotxyz/status/2114123657131761969/video/1
Community shows genuine enthusiasm for Cloak's privacy features on Solana, with particular excitement around the VKX Wallet integration enabling private SOL transfers using zero-knowledge proofs. Users appreciate the technical implementation and privacy-first approach.
First private SOL transfer on mainnet with @cloak_ag inside VKX Wallet 🛡️ 0.1 SOL delivered, sender wallet hidden from the recipient. ZK proof generated on the phone, keys never leave the device. Now in testing (beta) inside VKX. More soon.
@cloak_ag love it guys, let's talk privacy 🤫
@cloak_ag love it!
@ProofOfExploit @cloak_ag @colosseum Fast and cheap
@VkxTech @cloak_ag privacy first! 🥷

Cloak is a privacy stack for Solana built around a shielded UTXO model and zero-knowledge proofs, giving treasury teams, wallets, and protocols private deposits, transfers, withdrawals, and swaps with verifiable on-chain guarantees. The stack spans three public surfaces: the TypeScript SDK for proof generation, transaction building, and scanning; a Shield Pool program handling on-chain verification and state transitions; and a circuit package for Groth16 artifact generation and verifier-key export. Spends are protected by nullifiers, transaction history stays private by default via encrypted chain notes, and registered viewing keys enable controlled compliance export — built for privacy-focused wallets, protocol operators, and regulated/institutional operators that need auditability without exposing user data on-chain.
