What Is Post-Quantum TLS for Wallets?
Post-quantum TLS (Transport Layer Security) protects wallet-to-server communications using quantum-resistant key exchange and authentication. When your wallet connects to nodes, exchanges, or APIs, Kyber-based key establishment and SPHINCS+ certificates prevent quantum attackers from intercepting data.
Standard TLS vulnerability: Current TLS 1.3 uses ECDHE key exchange. A quantum adversary recording encrypted traffic can retroactively decrypt it once capable quantum computers exist. All historical wallet communicationsโtransaction data, balance queries, authenticationโbecome exposed.

Post-quantum TLS integration uses Kyber for key encapsulation during handshake. The session keys derived from Kyber resist quantum attack. Combined with classical ECDHE in hybrid modes, connections remain secure against both classical and quantum adversaries.
Authentication with SPHINCS+ replaces RSA or ECDSA server certificates. The server proves its identity using quantum-resistant signatures. Client authentication, where required, similarly uses SPHINCS+ certificates.
Chrome and Firefox already use hybrid ML-KEM key exchange by default, and OpenSSL 3.5 (2025) ships ML-KEM. Wallet implementations must adopt these libraries or implement compatible quantum-resistant TLS directly.
Privacy implications extend beyond transaction content. Traffic analysis reveals which addresses a wallet queries, which services it uses, and usage patterns. Post-quantum TLS with encrypted client hello (ECH) maximizes privacy protection.
SynX wallet communications benefit from Kyber-768 key exchange in transport security, ensuring that network traffic between wallet clients and SynX infrastructure resists quantum interception alongside SPHINCS+ authenticated connections.
