Lock.com has unveiled a new isolated crypto wallet featuring post-quantum security, set to launch in 2026.
Lock.com has announced the launch of an innovative isolated crypto wallet designed to enhance security through a non-custodial structure and post-quantum cryptography. Set to debut in the second quarter of 2026, the wallet is currently available in early access.
This wallet distinguishes itself from traditional hardware wallets by allowing users to utilize any existing device as an offline transaction signer, eliminating the need for specialized hardware.
The wallet's architecture is composed of three key elements:
- Signer — an offline device that securely stores private keys and seed phrases, disconnected from the internet;
- Wallet — an application that generates unsigned transactions and transmits them to the Signer using QR codes, Bluetooth, or local Wi-Fi;
- Node — a component that receives signed transactions from the Signer and broadcasts them to the blockchain network.
Lock.com supports over 117 different blockchains, covering various ecosystems such as EVM-compatible networks, Bitcoin's UTXO model, and others including Solana, Cosmos, and Polkadot.
Advanced Post-Quantum Security
The wallet incorporates hybrid post-quantum cryptography, utilizing the ML-DSA-65 and ML-KEM-768 algorithms, which were standardized by NIST in 2024. The key generation process is fortified by six layers of protection.
Rather than the conventional seed phrase of 12 to 24 words, Lock.com introduces a Universal Quantum Seed—a system of 256 icons that can be used across 42 languages, allowing for seamless backup and recovery. The seed boasts an entropy of 272 bits, which developers assert is resilient against potential quantum threats.
Additional Capabilities
Beyond cryptocurrency transactions, Lock.com features:
- An encrypted messaging service utilizing post-quantum hybrid cryptography for secure personal and group communications, as well as file transfers up to 100 MB;
- Decentralized storage built on the Filecoin network, enabling data packaging, signing, and storage without intermediaries;
- Smart contract interaction directly from the wallet interface.
The platform's code will be open-source, allowing for independent verification of its cryptographic implementations.
As the quantum threat looms, recent research highlights that a mere 500,000 physical qubits could potentially compromise Bitcoin and Ethereum within minutes. In response, developers are proposing updates to Bitcoin's BIP-360 to introduce post-quantum addresses and have initiated discussions on freezing coins at risk from quantum attacks.
The Ethereum Foundation has also formed a team dedicated to addressing post-quantum security, with plans for a roadmap to transition by 2029, including four hard forks aimed at enhancing security measures.
For those interested, the waiting list for Lock.com is now open on their website.
