Your transactions are already being collected
The Harvest Now, Decrypt Later (HNDL) threat is real — and your wallet may already be a target.
Harvest Now
Nation-state attackers are harvesting encrypted blockchain data and public keys exposed in transactions today.
Store & Wait
Petabytes of encrypted data are being stored, waiting for quantum computers powerful enough to break ECDSA.
Quantum Arrives
Cryptographically-relevant quantum computers are projected by 2030-2035. The timeline is accelerating.
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.
Quantum Scanner
Comprehensive wallet vulnerability assessment. Analyze exposed public keys, reused nonces, and asset risk in seconds.
Safe Guard
Post-quantum policy enforcement for Safe (Gnosis) multisig wallets. Protect DAO treasuries from quantum threats.
Migration Planner
Plan and execute your ECDSA-to-PQC key transition with zero downtime. Step-by-step migration for any chain.
How It Works
Three steps to make your blockchain application quantum-ready.
Install
npm install @quantumsafe/sdkScan or Sign
import { QuantumSafe } from '@quantumsafe/sdk'
const qs = new QuantumSafe({ apiKey: '...' })
await qs.scan.wallet({
address: '0x1234...abcd',
chain: 'ethereum',
