Why GuardBlock
Lose a device, not your Bitcoin
If a hardware wallet is lost or destroyed, your vault can be recovered with GuardBlock’s co‑signature.
Stops remote attacks
Malware can’t move funds on its own-transactions require your approval and our co‑sign.
Protection from coercion
Large withdrawals include a safety delay, giving time to cancel if you’re under pressure to send.
Easy setup
Connect your hardware wallet and start protecting your Bitcoin in minutes - no software installs.
Built‑in inheritance
Optional safeguards let trusted people recover funds if something happens to you.
Proven track record
Built by the team behind HardBlock - Australia’s longest‑running Bitcoin‑only exchange.
How it works
-
Spin up your GuardBlock vault with your hardware device(s) while we hold a separate co‑signing key.
-
Fund the vault: everyday security uses a 2-of-2 path-your signature plus ours-to stop malware and rogues.
-
Make withdrawals whenever you need. Small amounts clear instantly once we co‑sign according to your policies.
-
Prefer to move coins solo? Use the built-in timelocked path to spend independently with just your keys after the delay expires.
-
Add optional inheritance and recovery contacts so funds can be unlocked safely if you’re unavailable.
Plans
Choose the setup that fits your comfort level-every option keeps your Bitcoin protected and always spendable.
You bring 1 hardware device
GuardBlock pairs with your single hardware wallet, adding our co-signing key so you always have a trusted recovery path without sacrificing day-to-day access.
You bring 2 hardware devices
Keep both of your hardware keys in rotation while GuardBlock stands by as the resilience layer, enabling dual approvals for instant spends and timed recovery if either device is lost.
