The Lock.com project has introduced the concept of an isolated crypto wallet—a non-custodial wallet featuring a split transaction signing architecture and integrated post-quantum cryptography. The platform is set to launch in the second quarter of 2026, with the product currently in early access. This was reported by the wallet's developers to ForkLog.

Unlike traditional hardware wallets, Lock.com does not require a special device. The platform transforms any existing user device into an offline machine for signing transactions.

The architecture consists of three components:

  • Signer — a dedicated offline device that stores private keys and seed phrases. This device is not connected to the internet;
  • Wallet — a wallet application that creates unsigned transactions and sends them to the Signer via QR code, Bluetooth, or local Wi-Fi;
  • Node — a node that receives the signed transaction from the Signer through the Wallet and broadcasts it to the network.

The platform supports over 117 blockchains, including EVM ecosystems, UTXO architectures like Bitcoin, as well as Solana, Cosmos, and Polkadot.

Post-Quantum Cryptography

Lock.com employs hybrid post-quantum cryptography. It is based on the ML-DSA-65 (digital signatures) and ML-KEM-768 (key encapsulation) algorithms, which were standardized by NIST in 2024. The key derivation process features six layers of protection.

Instead of the usual 12–24 word seed phrase following the BIP-39 standard, the project offers a Universal Quantum Seed—a system of 256 icons adapted to 42 languages. A backup created in one language can be restored in any other. The seed's entropy is 272 bits—developers claim this is sufficient to guard against Grover's algorithm attacks.

Additional Features

In addition to storing and sending cryptocurrencies, Lock.com includes:

  • an encrypted messenger with post-quantum hybrid cryptography—supporting personal and group messages, file transfers up to 100 MB through node infrastructure;
  • a decentralized storage based on Filecoin—packaging, signing, and storing data without intermediaries;
  • interaction with smart contracts directly from the wallet interface.

The platform's code will be open-source, allowing independent researchers to verify the implementation of cryptographic algorithms.

The Quantum Threat

In March 2026, Google researchers found that fewer than 500,000 physical qubits may be sufficient to break Bitcoin and Ethereum—20 times lower than previous estimates. Their calculations suggest that the computations would take 9–12 minutes, fitting within Bitcoin's block time (~10 minutes).

The industry is evolving. Developers are discussing a proposal to update Bitcoin BIP-360, which would introduce a new type of address using post-quantum cryptography. Additionally, Casa co-founder Jameson Lopp and a group of experts presented a draft BIP-361—an initiative to freeze coins vulnerable to quantum computers.

In January 2026, the Ethereum Foundation formed a dedicated team for post-quantum security, and in March published a roadmap for four hard forks aimed at completing the transition by 2029.

As a reminder, on April 24, independent researcher Giancarlo Lelli calculated a 15-bit cryptographic key on ECC using a publicly available quantum computer. Project Eleven awarded the researcher 1 BTC as part of the Q-Day Prize program.
