Two hardware wallet stories shook self-custody in 2026. What happened, and why I’m bullish on @Tangem 👇 🧊 July: Coldcard A firmware bug had been weakening seed generation for years. Attackers recomputed the keys offline. 1,700+ BTC stolen from thousands of addresses, and nobody had to touch a single device. 📦 October: Ledger Ledger is investigating wallet drains among people who bought from one authorized reseller in Southeast Asia. It asked that reseller to pause sales. The cause is still unclear and no tampering has been confirmed. No victory lap here. People lost real money. Both stories point at the same two spots: how your key is born, and where your device comes from. Why I’m bullish on @Tangem: ▸ Seedless setup: the key is generated on the EAL6+ chip inside the card. No seed phrase to write down, photograph or leak. ▸ Firmware is fixed at the factory. No update channel for anyone to hijack. ▸ Backup is a second or third card, not a sheet of paper. ▸ Audits by Kudelski Security (2018) and Riscure (2023). ▸ I know of no documented case of funds stolen through a hacked Tangem card. The honest part: no wallet is flawless. Ledger’s own research team has shown a laser attack on Tangem cards. It needs the physical card and a lab worth around $250k, and fixed firmware also means no patch. So my rules stay boring: Official shop only Backup cards stored apart Card missing? Move the funds with the backup Boring is bullish. What’s your one non-negotiable?
