Tectonic Labs has released PQ Wallet, a browser-based EVM extension supporting Falcon-512 quantum-resistant signatures. The implementation operates at the application layer, maintaining compatibility with Ethereum Virtual Machine (EVM) chains without necessitating modifications to Layer 1 protocols. The wallet is currently available for Chrome and Firefox, with additional command-line interface (CLI) support for automated developer workflows and integration into existing protocol infrastructures.
The architecture provides two distinct operating modes to manage the transition from classical to post-quantum cryptography. The “Quantum-secure” mode utilizes Falcon-512 signatures immediately, which results in higher transaction fees due to the increased data size of quantum-resistant keys and signatures. The “Quantum-ready” mode employs classical signing for current economic efficiency while pre-configuring post-quantum parameters during account creation, allowing for a modular upgrade to quantum resistance without requiring a full wallet migration.
Alongside the software interface, Tectonic Labs has introduced PQ Audits to assist protocols in mapping cryptographic dependencies and identifying quantum-relevant risks. These assessments range from documentation-based reviews aligned with CNSA 2.0 and NIST standards to full-scope code audits that generate a cryptographic bill of materials. The service is designed to produce executable migration plans that account for governance timelines and the coexistence of legacy and post-quantum systems during staged rollouts.
