Unlinkable Confidential Payments

Quantum-resistant privacy for on-chain payments. Send funds that only the recipient can see. Withdraw to fresh wallets with zero on-chain link.

Vault Privacy Metrics

Sender encrypts payment details using the recipient's CIFER and deposits funds into the Privacy Vault. Amount and memo are quantum-encrypted.

Only the recipient can decrypt the claim ticket using their CIFER. No one else -- not even the blockchain -- can see the payment details.

Recipient generates a fresh wallet and withdraws there. The new wallet has zero history, making the payment completely unlinkable.

Selective privacy: Encrypted claim tickets + unlinkable withdrawals. Sender address visible on-chain.

Encryption quantum-safe: ML-KEM-768 (NIST post-quantum). Blockchain signing (ECDSA) is not yet quantum-safe on any EVM chain.

Contract decentralized: On-chain logic is permissionless. CIFER key management relies on Ternoa's enclave network.

ML-KEM-768 (NIST post-quantum standard) protects encrypted claim tickets against future quantum computers.

Fresh wallets have zero transaction history, breaking any on-chain link between sender and recipient.

Payment details (amount, memo, claim secret) are encrypted on-chain. Only the recipient can decrypt.

Nullifiers are marked as used after claim, preventing re-use of the same claim ticket.
