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.

Unchained Capital’s developer surface includes support, engineering blog, pricing, signup flow, changelog, and 11 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime (on an ambiguous tag, where no other regime matched), so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/unchained-capital: open an issue to ask a question, or submit a pull request to add artifacts.
