QSIG Wallet Shield is an experimental research tool designed for Chrome that focuses on post-quantum cryptography, specifically through the implementation of the ML-DSA (Dilithium) algorithm. This add-on logs signature attempts during wallet transactions, providing users with insights into quantum-resistant signing processes without altering any actual transactions. It serves as an educational tool for those interested in the evolving field of quantum security.

The extension boasts several features, including the ability to log quantum signature attempts directly in the browser console, ensuring a hands-on learning experience. Importantly, it does not collect or transmit any user data, and all key storage is handled locally, prioritizing user privacy. QSIG Wallet Shield stands as a proof-of-concept tool, making it an intriguing option for researchers and enthusiasts in the realm of quantum cryptography.
