Five layers of quantum security between your agent and the blockchain. Every transaction scanned, scored, and secured in under 10 milliseconds.
Every agent transaction passes through QShield before hitting the Solana network. The interception layer sits between the agent's signing process and the RPC broadcast, adding zero friction to safe transactions.
QShield identifies the cryptographic signature scheme used in each transaction. ECDSA-based signatures are flagged as quantum-vulnerable. Post-quantum schemes like ML-DSA and SLH-DSA are approved automatically.
Continuous on-chain monitoring tracks public key exposure. Keys that have been used to sign multiple transactions have higher exposure scores. QShield alerts agents before their keys reach critical exposure thresholds.
Multi-factor quantum risk score from 0 (safe) to 1 (critical). Factors include signature scheme, key exposure, address reuse, scope breadth, and agent age. The score determines whether a transaction is broadcast or blocked.
When a vulnerable key is detected, QShield provides automated migration pathways. Agents can migrate assets to fresh keypairs with zero downtime using the SDK's migrate() method.
