what's Unchained?

Unchained is a Bitcoin-native financial services company founded in 2016, specializing in collaborative custody multisignature (multisig) vaults that enable users to self-custody their Bitcoin while leveraging the company's hardware security and concierge support for setup, recovery, and management. Their model emphasizes user sovereignty—"not your keys, not your bitcoin"—with services including key ceremony facilitation, vault upgrades from singlesig, and tailored strategies for high-net-worth individuals and businesses through Unchained Signature. Beyond custody, Unchained offers Bitcoin-backed loans without forced selling, self-directed Bitcoin IRAs with client key control, a trading desk for direct vault purchases and rebalancing, inheritance planning for secure heir access, and business vaults for team multisig. They secure over $10 billion in Bitcoin for thousands of clients and produce research like the Bitcoin quantum computing paper with ARK Invest, focusing on long-term ecosystem resilience with a low time preference philosophy.
