Tectonic PQ Wallet

Quantum-secure wallet for Ethereum and EVM compatible blockchains. Post-quantum protection behind familiar UX.

Tectonic PQ Wallet is a quantum-secure wallet for Ethereum and EVM compatible blockchains. It looks and feels like a familiar smart account wallet while your keys, approvals and treasury operations use quantum resistant protection behind the scenes. The extension is designed for teams and power users who expect to hold significant value onchain through the 2030 and 2035 NIST cryptographic transition phases. It gives you a clear path away from vulnerable signatures without forcing a rewrite of your existing wallet stack or dApp integrations. Use Tectonic PQ Wallet to secure treasuries, institutional wallets, DAO vaults, long lived addresses and high value user accounts that cannot afford a rushed migration later. KEY BENEFITS Post quantum security for Ethereum wallets, vaults and dApps with familiar UX. A migration plan that anticipates NIST timelines instead of reacting at the last minute. Institutional governance features for teams, DAOs and enterprises. Ethereum native design that respects current standards, tools and dApps. HOW IT WORKS IN THE BROWSER Install the Tectonic browser extension and create a new wallet; the extension generates quantum-resistant Falcon-512 keys from the start. Each account is an ERC-4337 smart contract wallet, giving you a single address that supports both traditional ECDSA and post-quantum signatures. Connect to any dApp that works with MetaMask or other Ethereum-compatible wallets; Tectonic appears alongside them via standard wallet discovery. When you approve transactions, the extension's background service worker handles key management and signing in an isolated security context, then submits user operations through the bundler. You click approve and transact as usual, the cryptographic complexity of post-quantum proofs runs behind a clean interface. TWO ACCOUNT TYPES FOR YOUR SECURITY POSTURE Tectonic Wallet offers two account types so you can choose the right level of post-quantum protection and adopt PQ security at your own pace. - Quantum-Ready accounts deploy with both ECDSA and Combined (ECDSA + Falcon-512) signature schemes enabled. Use traditional ECDSA signatures for lower gas costs on everyday transactions, and switch to Combined signatures when you need quantum-resistant security. You can upgrade to Quantum-Secure at any time. - Quantum-Secure accounts enforce Combined signatures from day one; ECDSA-only is disabled at deployment. Every transaction requires both classical and post-quantum signatures, providing maximum security against future quantum threats at higher gas cost. Both account types are ERC-4337 smart contract wallets. You can run multiple accounts with different security postures under one wallet, choosing per-transaction which signature scheme to use on Quantum-Ready accounts, or committing to full PQ protection with Quantum-Secure. ETHEREUM NATIVE COMPATIBILITY Tectonic PQ Wallet is built on Ethereum standards from day one. It aligns with smart account and signature patterns so it can sit inside today's infrastructure instead of forking it. - Smart contract signature validation through EIP-1271. - Account abstraction and richer wallet logic through ERC-4337. - Modular smart account architecture through ERC-7579. The extension is compatible with Uniswap, Aave, OpenSea, Compound and other EVM dApps that already expect EIP-1271 signatures. Existing dApp integrations stay intact while the signature layer becomes quantum-ready. - ERC-4337 Account Abstraction: Each account is a smart contract wallet with bundler-based transaction submission, enabling gas sponsorship and batch operations. - EIP-1271 Signature Validation: Smart contract signatures work with any dApp that supports this standard, including Uniswap, Aave, OpenSea, and other major protocols. - EIP-1193 & EIP-6963 Provider: The extension appears alongside MetaMask and other wallets through standard wallet discovery, requiring no dApp changes. OPEN, AUDITED AND BATTLE TESTED Tectonic PQ Wallet is built on open implementations and battle tested modules. The wallet is designed to be audited, monitored and continuously improved. - Modular architecture that reuses proven components where possible. - Independent security audits by specialist firms. - Ongoing bug bounty coverage for responsible disclosure. This focus on verification and review gives teams confidence that the implementation can stand up to long term adversaries. SIMPLIFIED UX The wallet is built to be simple by design. Quantum security runs in the background and stays out of the way. - Interfaces that feel like familiar Ethereum wallets and smart account dashboards. - No extra steps for everyday signing and approvals. - A clean interface that handles post-quantum cryptography behind the scenes; users approve transactions without needing to understand Falcon-512 signatures or ERC-4337 user operations. - Simple upgrade flows so existing wallets can move to post quantum safety without seed phrase changes. Users do not need to understand PQC to enjoy its benefits. APPLICATION LAYER INTEGRATION Tectonic PQ Wallet operates at the application and wallet layer on top of existing Ethereum networks. It does not require protocol hard forks or special chain variants. This keeps deployment and testing focused on wallets, vaults and dApps rather than consensus changes. Post-quantum security comes from smart contract wallets. No hard forks, no special chain variants, no consensus changes are required. The architecture is chain-agnostic: any EVM network with ERC-4337 bundler support can run Tectonic accounts.
