Hardware Wallet Comparison
A good Bitcoin hardware wallet should verify transactions on its own screen, sign without a live computer connection, protect the seed with secure elements, use open standards, and avoid remote-validation servers. Use this table to compare devices against those security requirements.
Our 7 non-negotiable criteria, applied to six current devices. Linked notes point to primary product documentation and public security research.
