CIPNFT stands for Cryptographic Information Protocol NFT (aka Cipher NFT). Metadata is encrypted in the browser and stored as ciphertext fully on-chain. Transfers update a compact on-chain key envelope, so only the current owner (or an optional view-key holder) can decrypt. Encryption is standard by default, with an optional quantum-resistant envelope mode for long-term confidentiality.
// THE MARKET
// PROTOCOL
CIPNFT stores ciphertext on-chain. Encryption happens client-side using XChaCha20-Poly1305 with a per-token 32-byte DEK. The DEK is stored as an on-chain owner envelope and re-wrapped on transfer. Standard mode uses a compact envelope; an optional quantum-resistant envelope mode is available for long-term confidentiality. Tokenization is gated by on-chain Terms (versioned acceptance) and on-chain fees (flat + per-byte).
