Hardware wallet breaches cost users over $240 million in 2026

  • —Coldcard firmware weakened seed randomness from March 2021; 1,800+ BTC worth $100–150 million stolen
  • —Ledger Nano X and Nano S Plus units from CryptoBilis carried implants; losses of $90–100 million by mid-October
  • —Axis Intelligence estimates total hardware wallet losses for the year at about $241 million
  • —Galaxy Research says Coldcard breach funds remained largely unmoved as of mid-October
Why it matters: The breaches erode confidence in self-custody and could push investors toward multisig setups and regulated custodians.
