ZK-X402 under the hood

The three core components of our privacy payment protocol

1

Privacy Relayer

Payment Anonymization

Routes payments through secure relayer infrastructure, breaking the direct link between sender and receiver for complete transaction privacy.

Input: Payment Request
{
"amount": "0.1 BNB",
"merchant": "0x..."
}
Output: Attestation
zk://payment-verified
Verified
2

JWT Attestation

Cryptographic Proof

Generates cryptographic attestations that prove payment completion without revealing transaction details or wallet addresses.
