Collaborative Custody — How It Works & Best Providers

Collaborative custody uses multisignature technology where keys are split between you and a service provider. Typically in a 2-of-3 setup: you hold 2 keys, the provider holds 1. You can always move funds independently, but the provider can assist with recovery if you lose a key. This bridges the gap between full self-custody and third-party custody.
