Coldcard vs Trezor: Which Bitcoin Hardware Wallet Is Better for Security?
Coldcard and Trezor both appeal to people who care about open-source Bitcoin security, but they solve different problems. Coldcard leans into Bitcoin-only, microSD-based air-gapped workflows and advanced multisig. Trezor Model T is easier to learn, easier to recover, and a better fit when you want strong security without turning daily wallet use into an operations project.
