Maximum Security, Unlimited Chains
Keystone is an open-source air-gapped hardware wallet designed for maximum security and transparency. Equipped with a 4-inch touchscreen and 3 secure elements, it also supports 3 seed phrases to meet diverse user needs. Over 6 years, Keystone has evolved from serving Bitcoin maximalists to addressing the broader Web3 ecosystem, offering top-tier multi-signature solutions for Bitcoin and tackling blind signing issues for Ethereum and Solana.
By integrating SwapKit’s infrastructure through their Nexus companion app, Keystone users can now access decentralized liquidity protocols while maintaining their signature air-gapped security model. This integration delivers:
✅ True native cross-chain swaps: Trade native BTC for ETH, or USDT for USDC without wrapped tokens
✅ Air-gapped security: Maintain Keystone’s signature offline security model with QR code-based transaction signing
✅ Best-in-class user experience through the intuitive Nexus mobile interface
✅ Self-custody first: Users retain complete control over their private keys and assets
This integration aligns perfectly with SwapKit‘s goal to enable seamless cross-chain experience for all web3 users, without compromising on self-custody.
