Three rails. Three distinct trust models. ✦
Article IV. Your keys stay aboard. Coldharbor cannot recover what it never receives.
Trust boundaries
01Key creation, on device
Keys are generated by your device's CSPRNG and never serialized.
02Signing, localLocal signing, relay online
Transactions are signed in local memory; only signed bytes leave.
03Identity, none required
No email, no phone, no KYC. The wallet has no concept of you.
04Wallet telemetry, none
No analytics SDK, no crash uploads, no fingerprinting.
05Recovery, user controlled
Your seed phrase is the only recovery path. We cannot reset it.
