Tectonic Labs Announces PQ Wallet, PQ Audits as Web3 Prepares for Post-Quantum Signature Migration
Tectonic Labs announced PQ Wallet, a post-quantum-ready EVM wallet extension supporting Falcon-512 signatures without requiring L1 changes, alongside PQ Audits that help teams assess quantum risk and plan NIST-aligned migrations.
Tectonic Labs today announced PQ Wallet, a post-quantum ready EVM wallet extension for Ethereum and EVM chains, and the immediate availability of PQ Audits for protocols, wallets, and infrastructure teams.
Post-quantum migration has moved from research to execution planning. Wallets and signing flows sit on the critical path for user authentication and transaction authorization, and a late transition tends to compress work into rushed cutovers, brittle integrations, and avoidable operational risk.
PQ Wallet is built to make the transition deployable without requiring L1 changes. It runs at the application layer and supports quantum-resistant signatures using Falcon-512, while preserving EVM compatibility and common wallet workflows.
PQ Wallet offers two operating paths. Quantum-secure uses post-quantum signatures from day one for users who want maximum long-term protection and accept higher fees from larger keys and signatures. Quantum-ready keeps classical signing for normal EVM economics today while pre-configuring post-quantum at creation, so the future switch is an upgrade step rather than a migration project.
PQ Wallet is delivered as a browser extension for Chrome and Firefox, with CLI support for teams that need automation and integration into developer workflows. The wallet has been audited by Halborn and Quantstamp.
PQ Audits are available immediately for teams that need a readiness baseline and an executable migration plan under real constraints, including governance timelines, integration burden, and staged rollouts where legacy and post-quantum systems must coexist. Audits are designed to map cryptographic dependencies across the stack, identify quantum-relevant risk, and produce a NIST-aligned transition plan.
Tectonic offers two audit scopes. The One Day PQ Audit is a documentation-based assessment that surfaces critical systems relevant to post-quantum transition and delivers an executive-ready plan aligned to CNSA 2.0 and NIST direction. The Full Scope PQ Audit extends into documentation plus code to produce a cryptographic bill of materials, identify quantum-relevant risk locations, and deliver prioritized remediation guidance across signing and verification paths.
“Post-quantum signatures are now a scheduling and integration problem as much as a cryptography problem,” said Mike Berman, co-CEO of Tectonic Labs. “The risk is that teams wait until the ecosystem forces a change and then scramble through a high-stakes cutover. The constraint is that upgrades touch many dependencies and have to be staged without downtime. The pragmatic path is to measure exposure now and ship a controlled transition.”
“Wallets are where post-quantum readiness becomes real for users and developers,” said Ron Kahat, co-CEO of Tectonic Labs. “You need an EVM-compatible path that can introduce quantum-resistant signatures without breaking existing workflows. If teams design for coexistence early, they can migrate deliberately. If they wait, they retrofit under pressure.”
PQ Wallet early access sign-ups open today, and PQ Audits are available immediately. A broader PQ Wallet release is planned for later in 2026 for protocols, developers, and end users that need a controlled path to post-quantum signatures on EVM chains.
