Keystone

Keystone, founded in 2017 by Lixin Liu, develops cryptocurrency hardware wallets designed for secure, offline asset management. Originally launched as Cobo Vault in 2018 and rebranded to Keystone in 2021, the company is headquartered in Shanghai, China. The firm's initial seed funding round in mid-2022 included investors like Qiming Venture Partners.

The core business revolves around the sale of its hardware wallet devices, which provide cold storage for digital assets by remaining completely disconnected from the internet. The wallets are 100% air-gapped, using QR codes for transaction data transmission instead of riskier connections like USB, Bluetooth, or Wi-Fi. This design minimizes the attack surface for malware and remote hacking attempts. The company serves a global market of cryptocurrency users, from long-term holders to active DeFi participants, who prioritize security.

Keystone offers several product versions, including the Keystone Pro, which features a 4-inch touchscreen, a fingerprint sensor, and a rechargeable battery. Security is a major focus, with features such as multiple bank-grade Secure Elements, anti-tamper self-destruct mechanisms, and open-source firmware for transparency. The wallets support over 5,500 cryptocurrencies across various blockchains, including Bitcoin, Ethereum, Solana, and EVM-compatible chains. Keystone devices integrate with popular software wallets like MetaMask, Solflare, and others, allowing users to securely sign transactions initiated on those platforms.
