| Tool | What it does |
|---|---|
| Hardware wallet risk checker | Whether your device and firmware fall inside a known security advisory — including the cases where a firmware update does not help, and flaws that will never be patched |
| Self-custody audit | Nine questions, scored /27, aimed at backup and inheritance — the failure modes that actually lose coins |
| Public track record | Every dated call we've made, graded. Losses included |
Static HTML and vanilla JavaScript. Everything runs in your browser — nothing you enter is transmitted anywhere, and there is no backend to transmit it to.
No tool here will ever ask for a seed phrase. Neither will any legitimate one.
advisories.json carries every hardware-wallet advisory the checker uses. Each entry cites the
vendor advisory, researcher disclosure or CVE it came from. Two fields matter most and are the
reason this exists at all:
seed_compromised— the seed itself is exposed, so updating firmware does not make you safepatchable: false— no fix will ever exist, so "update your firmware" is actively wrong advice
scorecard-data.json is generated from our internal ledger; it is not hand-edited.
Found something wrong or out of date? That is genuinely worth knowing — reply to any issue of the newsletter and it gets fixed. Accuracy here matters more than being first.
Not financial, security, tax or legal advice. Verify against your vendor's own advisory before acting.
