Insured Bitcoin custody using time-locked multisig (Trident) — keys stay distributed while the bitcoin carries real insurance. US.
AnchorWatch offers insured Bitcoin custody using a time-locked multisig design, so the bitcoin stays secured by distributed keys while also carrying real insurance against loss or theft. It is a rare combination — most custody is either self-held-but-uninsured or insured-but-custodial.
It targets US holders and businesses who want the sovereignty of multisig but also the backstop of a policy, particularly for larger amounts where "just don’t lose the keys" is not a comfortable plan. The trade-offs are regulatory and geographic, and the model is newer than plain self-custody, so it suits those who specifically value insurance alongside distributed keys.
