Signing devices are scored on six dimensions weighted toward key generation, rather than on the rubric used for custody services. Assessment as of August 3, 2026.
Open-source entropy path with optional user-supplied entropy, independently auditable. No publicly documented defect.
Fully open source with reproducible builds, the strongest transparency position in the category. Older models without a secure element remain vulnerable to documented physical-extraction attacks given device access.
Tamper-evident packaging and holographic seals, with documented historical counterfeiting of devices through unofficial resellers.
Has generally acknowledged physical-attack research openly and published mitigations rather than disputing findings.
Standard descriptors and broad wallet compatibility. No shipped miniscript support, which limits use with policy-based vault designs.
A 2024 breach of the third-party support ticketing system exposed contact details for a subset of users. Materially smaller in scope than the 2020 Ledger incident.
Pioneer hardware wallet. Open source. User-friendly. Broad coin support.
Physical exposure. Extraction vulnerabilities disclosed. Self-custody burden.
Trezor's custody insurance is not publicly disclosed.
Trezor uses a hardware wallet model and scores 71/100 in our independent review, including 75/100 on custody security. No single institution can unilaterally move funds. Safety depends on your priorities; see the full score breakdown above.
Trezor's custody insurance is not publicly disclosed in a form we can verify. Where it exists, custody insurance covers specific named events up to shared limits and does not cover price loss. Confirm coverage in writing before relying on it.
Trezor's architecture distributes control, so no single institution's failure alone can move or lose your bitcoin. Recovery depends on the specific structure; see the custody section above.
Trezor does not advertise a dedicated inheritance or beneficiary feature in the data we track. Confirm current options with the provider, since custody inheritance handling changes.
