Ethereum Builders Live to feature PQ1 hardware wallet discussion

The quantum computing threat to crypto has always felt like a distant storm on the horizon. Freedom Factory apparently decided not to wait for the rain. The company unveiled the PQ1 on July 28, 2026, billing it as the world’s first hardware wallet built with post-quantum cryptographic capabilities. One day later, on July 29, Ethereum Builders Live will host a dedicated session featuring Freedom Factory CEO Michael Haas to break down the device’s security architecture and open-source design philosophy. What the PQ1 actually does The PQ1 tackles this by implementing SPHINCS+, a hash-based digital signature scheme that’s considered resistant to quantum attacks. Instead of relying on math problems that quantum computers might eventually solve, SPHINCS+ uses a different cryptographic approach that remains secure even against quantum-capable adversaries. Beyond the quantum-resistant algorithms, the wallet integrates ERC-4337 smart accounts. ERC-4337 is the account abstraction standard on Ethereum that lets users interact with the blockchain through smart contract wallets rather than traditional externally owned accounts. This means features like social recovery, gas sponsorship, and batc...
