Introduction
Hardware wallets are essential devices for safeguarding cryptocurrencies by storing private keys offline, shielding them from online threats. Open-source hardware wallets elevate security by allowing public scrutiny of their code, ensuring transparency and community-driven improvements. This guide explores the top 10 open-source hardware wallets, comparing their features, supported cryptocurrencies, and pros/cons to help you make an informed choice.
