About Us
We spent the last six years perfecting Hybrid Custody using Smart Vaults – a revolutionary Layer 2 protocol that makes Bitcoin and Altcoins UNSTEALABLE, UNLOSABLE, and UN-CONFISCATABLE.
Hybrid Custody solves the critical dilemma of Self-Custody vs. Managed Custody in crypto i.e. you risk loss and theft when you manage your own private-keys/crypto or risk fraud, capital controls, seizure, and more when you entrust the same to third-party custodians like Crypto Exchanges.
