The Privacy Standard
for Web3
Like HTTPS for the internet. One toggle to shield sender, amount, and recipient.
Privacy Made Simple
Enterprise-grade cryptography with a developer-friendly API
Stealth Addresses
One-time recipient addresses prevent transaction linkability. Each payment uses a unique address derived from the recipient's meta-address.
Hidden Amounts
Transaction amounts are hidden using Pedersen commitments. Solvers see cryptographic commitments, not actual values.
Viewing Keys
Selective disclosure for compliance. Share transaction details with auditors without exposing your full history.
Cross-Chain
Privacy works across any NEAR-connected chain. Swap between Ethereum, Solana, Zcash, and more with full privacy.
PRIVACY ACROSS 15+ CHAINS
