⚠️

Your transactions are already being collected

The Harvest Now, Decrypt Later (HNDL) threat is real — and your wallet may already be a target.

⚠️
NOW

Harvest Now

Nation-state attackers are harvesting encrypted blockchain data and public keys exposed in transactions today.

📦
COLLECT

Store & Wait

Petabytes of encrypted data are being stored, waiting for quantum computers powerful enough to break ECDSA.

QUANTUM ERA

Quantum Arrives

Cryptographically-relevant quantum computers are projected by 2030-2035. The timeline is accelerating.

🔓
DECRYPT

Decrypt Later

Your private keys are derived from exposed public keys. All past transactions become vulnerable retroactively.

Products

Everything you need to make your blockchain application quantum-resistant.

🔑

Keys & Signing

PQC key generation and hybrid attestation with ML-DSA and SLH-DSA. Drop-in replacement for ECDSA signing workflows.
