Upstream providers see the relay—not you.

Security without ceremony
Your keys stay where they belong.
Generated locally
Entropy begins on your device. ColdHarbor never receives a seed phrase or signing key.
Hardware protected
Secure Enclave and OS key stores gate signing behind biometrics and device security.
Signed, then sent
Transactions are built and signed locally. The relay only receives what the network needs.
Transparent by design
No hidden spread.
Every route shows network fees, provider fees, and the ColdHarbor fee before you sign.
