INSIGHT

Insurance Is The True Wrench Defense

The only true solution to a wrench attack is insurance.
Multi-institutional custody cannot prevent coercion when a gun is involved, so insurance is vital.

INSIGHT

How AnchorWatch Reinvents Bitcoin Insurance to Protect Against Wrench Attacks and Ensure Inheritance

AnchorWatch has pioneered a Bitcoin-native insurance solution combining advanced multisig custody with traditional Lloyd's of London coverage to protect self-custodial Bitcoin holders from wrench attacks, kidnapping, fraud, and inheritance issues.

Their unique approach uses Miniscript to create a vault where AnchorWatch holds a temporary signing key during the insurance period, enabling fraud protection and quick law enforcement response while ultimately reverting to pure self-custody once insurance ends.

They also built a foolproof inheritance protocol using time-locked multisig vaults that allow beneficiaries to regain access to Bitcoin without relying on fragile "treasure maps" or complex passphrases, addressing a major failure point for families.

AnchorWatch became the only retail-accessible Lloyd's crypto coverholder with these protections, managing challenges like insurance fraud concerns and creating a bridge between high-tech Bitcoin script and traditional insurance frameworks.

This innovation represents a critical evolution in Bitcoin security, delivering both protection and peace of mind for individuals and families safeguarding generational wealth.
