Hardware Wallets

A major blockchain exploit showed how stolen onchain funds can sometimes be traced and returned. The deeper risk for crypto users is identity data that cannot be rotated once exposed.

Coinkite has released new Coldcard firmware after a randomness flaw enabled attackers to steal more than $114 million in bitcoin. The company says AI-assisted review found additional issues, but users with affected seeds still need to create new wallets and migrate funds.

Attackers have drained nearly $114 million in bitcoin from more than 709 addresses after exploiting a Coldcard firmware flaw that weakened wallet seed randomness. The incident is forcing the self-custody community to confront uncomfortable questions about verification, reputation, and how security review is encouraged or discouraged.

SafePal disclosed a security incident that exposed names, physical addresses and contact details tied to customer orders. The crypto wallet provider said funds, seed phrases, private keys, bank information and government IDs were not affected.

Russian retailers reported a sharp increase in hardware crypto wallet sales as new rules for digital assets move closer. The surge highlights growing interest in self-custody, even as legal limits and device-security risks remain firmly in place.

A five-year-old Coldcard firmware flaw led to the theft of almost 1,600 BTC from around 7,300 addresses, intensifying debate over bitcoin self-custody. FXCOINZ finds that many affected holders are not abandoning self-custody, but are shifting toward collaborative multisig models designed to reduce single-device risk.

A Bitcoin wallet inactive since 2013 moved 500 BTC worth about $31.3 million on Monday, drawing attention as long-dormant coins began shifting on-chain. The movement comes during a broader security crisis tied to Coldcard hardware wallets, with market participants watching whether old holders are migrating funds out of caution.

Ledger has introduced Ledger Agent Stack, an open-source toolkit designed to let AI agents interact with crypto wallets without taking control of private keys. The system allows agents to read balances, analyze portfolios and prepare transactions, but sensitive actions must be approved on a Ledger hardware device before execution.
