Future-Proof
Security.
PyjusProtocol delivers post-quantum cryptography for digital assets, blockchains, and enterprise infrastructure. Ready before Q-Day arrives.
[ 01 ] Leadership
We're the leaders in post-quantum cryptography for digital assets.
Our research team publishes reference implementations, contributes to NIST standardization, and works directly with custodians and enterprises preparing for the quantum transition.
[ 02 ] Bitcoin Risq List
Is your Bitcoin address vulnerable to quantum attack?
Roughly 25% of all circulating BTC sits in address types with exposed public keys — the first targets when a cryptographically-relevant quantum computer arrives. Check any address in seconds.

Top 10 quantum-meets-blockchain myths
What Q-Day actually means for wallet holders, custodians, and infrastructure teams.
[ 05 ] How it works
Four steps from classical keys to a quantum-safe posture.
Inventory
Map every classical signing path across custody, wallets, and infrastructure.
Model
Rank each key by exposure, blast radius, and rotation cost.
Migrate
Deploy hybrid signers so PQC runs alongside ECDSA without disruption.
Monitor
Track NIST standards, quantum-progress signals, and downgrade attempts.
[ 06 ] Platform
One protocol. Every attack surface.
PyjusProtocol ships as modular primitives you can adopt one layer at a time — from a single wallet to an entire custody stack.
Hybrid Signers
ECDSA + Dilithium co-signing so upgrades never break clients that only speak classical.
Vault Recovery
Post-quantum shard recovery that stays private even under a store-now, decrypt-later attacker.
Bridge Guards
Signature-verification adapters for cross-chain bridges, wrapped in a crypto-agile interface.
Audit Trails
Signed, tamper-evident logs of every ceremony, key rotation, and algorithm handoff.
Threshold PQC
Multi-party ML-DSA signing for MPC custodians. Byzantine-fault tolerant by default.
On-chain Verifier
Solidity verifier contracts for post-quantum signatures on EVM chains.
[ 07 ] Roadmap to Q-Day
The next five years.
NIST FIPS 203/204 finalized
ML-KEM and ML-DSA officially standardized. Reference implementations begin shipping.
First enterprise migrations
Regulated custodians publish PQC transition plans. Hybrid signers hit production at multiple exchanges.
Consumer wallets ready
Account-abstraction wallets ship with default post-quantum recovery paths.
Bridges & rollups
Cross-chain infrastructure adopts PQC-verifier contracts. L2s pilot ML-DSA validator sets.
Est. cryptographically relevant quantum computer
Consensus window across expert surveys. Systems without a migration path become exploitable.
[ 08 ] Trusted by
Custodians, researchers, and protocol teams building on PyjusProtocol.
The clearest migration path we've seen. Their hybrid signer dropped into our HSM stack in a single sprint.
PyjusProtocol's Bitcoin exposure model changed how our board thinks about long-term reserve risk.
Open-source, well-audited, and actually usable. Rare combination in cryptography tooling.
[ 09 ] Frequently asked
Answers before you ask.
When is Q-Day?+
Expert surveys cluster around 2029–2034 for a cryptographically relevant quantum computer. The store-now, decrypt-later threat is already live — any signature or ciphertext captured today can be broken later.
Do I need to migrate my Bitcoin now?+
If you plan to hold beyond the Q-Day window, yes. Start by rotating funds off address types that expose public keys, then move to a quantum-safe custody stack for the long tail.
Is PyjusProtocol audited?+
Yes. Every reference implementation ships with third-party audits from at least two independent firms. Reports are published in the open on our GitHub.
Which chains do you support?+
Bitcoin, Ethereum, and every major EVM L2. Solana and Cosmos support ships in our next release.
Can I integrate without changing my HSM?+
In most cases, yes. Our hybrid signer runs alongside your existing HSM and adds a co-signature from a software or hardware-held PQC key.
How much does it cost?+
Open-source libraries are free. Enterprise engagements are priced against scope. Start with a briefing.
