As #Bitcoin adoption escalates to the level of nation-states, the risk of supply chain infiltration targeting hardware wallets will grow significantly. Historical precedents, such as the SolarWinds breach, demonstrate how sophisticated attackers can compromise widely used technology. In the context of Bitcoin, malicious actors could similarly infiltrate the supply chains of hardware wallets, such as #ColdCard to install malicious firmware. Relying solely on the device for verification is a significant vulnerability; multi-layered security measures are essential to mitigate these risks.
