Made Easy

Single Point of Failure

Bitcoin's greatest strength is also a weakness. A simple phrase, or 32 bytes of secret, can protect and move billions of dollars. Yet the risk of losing that secret creates huge burdens on the user. A single point of failure.

Solution: Multisig

The good news is that a solution already exists. Just like the two-man rule used to prevent accidental or malicious launch of nuclear weapons, multisig technology requires multiple keys to control funds. The bad news is that so far it has remained inaccessible to most. Well, until now.
