Wallet migration PQC | Quantum-Safe Claims & Education
Verdict
Wallet migration to PQC is a multi-year ecosystem problem, not a single app update. Chains, wallets, custodians, and dapps must support new verification rules—plan inventories and avoid panic migrations on rumors.
Overview
Unlike TLS hybrids on the web, blockchain migrations need consensus and wallet UX changes.
Educational steps: inventory keys, reduce address reuse, follow chain governance research, prefer crypto-agile wallet designs (e.g. AA) where appropriate.
Cryptographic profile
- Signatures: Today: classical chain signatures, Future: PQ or hybrid address schemes (chain-dependent)
- Hash: Chain-dependent
- Public-key exposure: Users and treasuries must move value when schemes change.

- Which chains have concrete PQ address migration proposals?
Educational analysis only. Verify primary sources, specs, and audits yourself before any financial or procurement decision.
What breaks
- Waiting for Q-Day headlines to move funds
- No inventory of where seeds/keys live
- Bridges that re-introduce classical multisigs
Mitigations
- Organizational crypto asset inventory
- Test AA/multisig operational agility now
- Watch standards and major chain research
FAQ
When should I migrate?
No universal date—use risk, shelf life of holdings, and chain readiness; not financial advice.
