Your recovery paths are built on Bitcoin timelocks, measured in blocks on the timechain. 🟧 They only become available if you don’t refresh your vault: ✓ After about 13 months of blocks, your key alone can move your Bitcoin ✓ After about 15 months of blocks, Guardblock can help you recover it Each time you refresh your vault, the countdown starts again. Your recovery paths stay closed while you’re active, and ready if you’re not. No calendars. No company clocks. Just the timechain. Want to see how it works?

Most people choose between two risks. Leave your Bitcoin on an exchange, and someone else controls it. Hold it yourself with one seed phrase, and one mistake can cost you everything. Guardblock removes the trade off. Every everyday transaction needs two signatures: yours and ours. You approve it on your own hardware wallet. We co-sign. What that means for you: ✓ We can’t move your Bitcoin on our own ✓ One stolen key isn’t enough to move it either ✓ If we ever disappear, your recovery path still opens Enforced by Bitcoin. Not by us.

Multisig is the gold standard for securing Bitcoin. The catch? Most people never set it up because it feels like a weekend project. We made it a 15 minute one.

Guardblock is built by the team behind @HardBlockBTC, securing Australians' Bitcoin since 2014. Same team. Same focus on security.

Without a plan, your Bitcoin could be lost forever. Guardblock builds inheritance into the vault, giving your family a clear path to the Bitcoin you worked so hard to stack and protect.

Every spending path is a branch in a Taproot miniscript policy, enforced by Bitcoin consensus, not by us. Our Vault Architecture Design lays it all out. The multiple-key design, the exact miniscript and the timelocks behind every vault. Read it, check it and hold us to it.

Practice Vaults are now live. Have a play with timelocks. Set up a vault with a few dollars of real Bitcoin, watch the timelocks open and rehearse your recovery in hours, not months. Test the safety net before you need it.

A guaranteed exit that doesn't depend on anyone, including us. The first timelock opens after ~13 months, enforced by Bitcoin's consensus rules, block by block. Rolling over refreshes the timelocks, so the safety net stays one. Bitcoiners get it. Our customers love it.

Most self custody setups rely on one thing. You never making a mistake. Not once, not ever. One lost backup and there's no reset button. Guardblock is the safety net.
