Unchained Capital
Unchained (Unchained Capital, Inc.) is an Austin, Texas bitcoin-native financial services company built around collaborative multisig custody. Clients hold bitcoin in 2-of-3 multisig vaults where the client holds two keys and Unchained holds one, so no single party — including Unchained — can move funds unilaterally, and clients can recover independently with open-source tooling such as Caravan and Sparrow. On top of that custody base Unchained offers a trading desk for buying and selling bitcoin directly to cold storage, bitcoin-backed loans, the Unchained IRA (Traditional, Roth, SEP and 401(k) rollovers), business and trust vaults, inheritance planning, and — through Gannett Trust and Gannett Wealth Advisors — fiduciary trust and wealth advisory services. Unchained publishes no public REST or GraphQL API; its public developer surface is a set of open-source bitcoin libraries (unchained-bitcoin, unchained-wallets, hermit, and the Caravan multisig coordinator, now maintained in the caravan-bitcoin organization) plus an llms.txt for AI agents.
Unchained Capital is profiled on the APIs.io network. Tagged areas include Company, Bitcoin, Cryptocurrency, Financial Services, and Custody.
