Bitcoin Collaborative Custody: The Unchained Guide

Last Verified: July 2026. Every figure in this guide was read directly from unchained.com on 21 July 2026.

This publication has spent the better part of two years documenting what Bitcoin buys — the Sanlorenzo, the Gulfstream charter, the Nautilus. Every one of those guides rests on an assumption so foundational it is rarely examined: that the Bitcoin funding the acquisition is actually secure. Not secure in the sense of a strong password, but secure in the way an eight-figure position demands — against device failure, against theft, against the holder’s own mortality, and against the single moment of error from which Bitcoin, uniquely among asset classes, offers no recovery.

Unchained exists for precisely this problem. The Austin-based firm has built its entire business on a custody model — collaborative custody — that occupies the deliberate middle ground between trusting an exchange with everything and trusting yourself with everything. By the company’s own published figure, one in every two hundred bitcoin that will ever exist is now secured in an Unchained vault. For the reader whose holdings underwrite the acquisitions this publication covers, it is the single most consequential piece of financial infrastructure we have yet reviewed.

What Collaborative Custody Actually Is

Every Bitcoin custody arrangement is an answer to one question: who holds the keys? The exchange account and the spot ETF answer someone else entirely — convenient, familiar, and precisely the arrangement that turned Mt. Gox, Celsius, and FTX into cautionary tales. Pure self-custody answers you alone — sovereign, censorship-proof, and dependent on a private individual executing institutional-grade operational security forever, without a single lapse. Neither answer suits serious wealth. The first reintroduces the counterparty risk Bitcoin was designed to eliminate; the second concentrates catastrophic risk in one person’s competence and continuity.

Collaborative custody answers you, with a structural safety net. An Unchained vault is controlled by three keys. Two are yours, held on hardware wallets you keep in separate locations. The third is held by Unchained. Any two of the three are required to move funds — which produces two properties that matter enormously and are worth stating plainly. First, Unchained cannot move your Bitcoin. One key is never enough; the company could be compromised, coerced, or simply wrong, and your position would not move. Second, you can lose an entire key — the device, the seed backup, all of it — and recover everything, because your remaining key plus Unchained’s key still meets the quorum. The single point of failure, the defining terror of self-custody, is engineered out of the structure rather than managed by discipline.

The model uses the same 2-of-3 multisignature architecture that institutional custodians run internally. The difference is where control sits: with the client, verifiably, on-chain. This is not an abstraction. A vault holder can — at any time, from any block explorer — confirm that the collateral exists, has not moved, and requires their signature to move. No quarterly attestation from an auditor approaches that standard of proof.

The Company Behind the Model

Unchained Capital, Inc. is headquartered in Austin, Texas, and is deliberate about what it is not: the footer of every page on its site states plainly that it is not a bank. It operates through licensed entities — Unchained Capital, Inc. (NMLS ID 1900773), Unchained Trading, LLC (NMLS ID 2273761), B&C Lending LLC (NMLS ID 2656661), and Bitcoin Collateral Services LLC (NMLS ID 2423070) — a regulatory posture worth noting because it is the opposite of the offshore structure common in crypto financial services. This is a US-regulated, US-licensed company whose obligations are enforceable in US courts.

The scale claims published on its own site, as of July 2026: more than $1 billion in loan originations across more than 1,000 loans, with — the figure the firm gives top billing — zero lost bitcoin. Alongside the custody and lending business, the firm has stood up Gannett Trust, which it describes as the first trust company designed for bitcoin holders, their families, and their fiduciaries — the qualified-custody and wealth-advisory layer for clients whose estates demand a corporate fiduciary.

The Vault: How the Architecture Works in Practice

A personal vault costs $250 per vault per year (Last Verified: July 2026). Setup requires two hardware wallets — the devices we compared at length in our Trezor versus Ledger guide both work — initialised and geographically separated. Unchained’s interface coordinates the multisig configuration; the client’s two keys never touch Unchained’s servers.

For readers who want the setup performed under supervision rather than alone, the firm sells Premium Service Suites: guided onboarding, an advanced security review, two hardware wallets, and the first year’s vault subscription, delivered across one-on-one video sessions. The Strengthen Your Setup suite (for holders already in self-custody moving up to multisig) is $1,650; Hold Your Own Keys (for those coming off an exchange) is $1,900; Retire with Bitcoin (built around an IRA vault) is $2,650. Each has a two-person edition — $2,400, $2,650, and $3,400 respectively — priced for couples establishing joint custody. (All Last Verified: July 2026.)

At the top of the range sits Unchained Signature: $6,000 for the first year, renewing at $4,500, for up to ten vaults — personal, trust, and IRA — a dedicated relationship manager, same-day emergency support, hands-on operational security reviews, two premium hardware wallets, preferred trading fees, and full inheritance setup and coordination for heirs. A business edition runs $7,500 per year (or $2,000 quarterly) with four hardware wallets and approval-quorum functionality for treasury teams. For a family office managing an eight-figure position, Signature is the correct entry point, and its pricing — less than the annual detailing budget of any car in our garage vertical — is trivial against the asset it protects.

The Bitcoin IRA: Keys Inside a Retirement Account

Unchained’s IRA is the product with no true competitor: a traditional, Roth, or SEP IRA in which the Bitcoin is held in a collaborative-custody vault and the account holder controls keys. Every other bitcoin IRA on the market is a custodial arrangement wearing a tax wrapper; this is the only one, by the company’s own positioning, that lets the client hold their own keys. Existing 401(k)s and retirement accounts roll over without triggering taxes or penalties, and the fee schedule is short: $250 per IRA account per year, no setup fee, a $2,000 minimum per USD transfer or contribution, and a 1.5% trading fee on transactions inside the account. It is available in the United States only. (Last Verified: July 2026.)

The strategic logic will be familiar to any reader of our tax guide: Bitcoin’s expected appreciation is the reason to hold it; a Roth wrapper makes that appreciation permanently tax-free; and key control removes the custodial risk that made serious holders dismiss bitcoin IRAs in the first place.

The Trading Desk: Acquisition Without the Exchange

The trading desk charges a 1.0% flat fee and settles purchased bitcoin directly into the client’s cold-storage vault — no exchange account, no withdrawal queue, no interval during which the position sits on someone else’s balance sheet. Sales work in reverse, from vault to dollars, with trades approved from the Unchained mobile app. Signature clients receive preferred rates. A defaulted trade incurs a cancellation fee of no less than $200 plus any market loss. (Last Verified: July 2026.)

For this publication’s purposes the desk matters in one specific scenario: the liquidation that funds a purchase. A reader selling seven figures of Bitcoin to close on the Miami penthouse can execute directly from multisig cold storage — the asset provably secure until the moment of sale — rather than staging the position on an exchange days in advance, which is exactly the window in which things go wrong.

The Lending Desk Went Commercial — and the Rate Depends on Where You Look

Two findings from this review need stating plainly, because eleven of our other guides cite Unchained as a lender and the landscape has shifted under them.

First: Unchained’s bitcoin-backed lending is now a commercial product. The loans page is explicit — “Bitcoin-backed loans for business” — with the borrower expected to be a company, a fund, or a family office rather than an individual. The minimum loan is $150,000, there is no credit check, payments are interest-only every 30 days with principal due at term, there are no prepayment penalties, and an institutional desk handles financings of $5 million and above. An individual seeking a personal bitcoin-backed loan for a luxury acquisition is no longer Unchained’s customer — that lane now belongs to Ledn, whose product we examined in The Ledn Guide. (Last Verified: July 2026.)

Second: Unchained publishes two different rates for the same loan. Its pricing page lists a 12.0% interest rate with a representative APR of 14.18% and a 2.00% origination fee. Its own loans-page calculator, in the same week, displays 14% interest and a 16.21% APR, footnoted as estimates from November 2025. Readers of our Ledn review will recognise the pattern — Ledn publishes four mutually inconsistent entry rates across its own site. The lesson is identical in both cases and we will keep repeating it: in bitcoin-collateralised credit, the published rate is an advertisement, not a term sheet. Obtain the rate in writing before pledging collateral. (Last Verified: July 2026.)

What distinguishes the Unchained loan structurally is where the collateral sits: in a 2-of-3 multisig vault in which the borrower’s company holds a key, Unchained holds a key, and Fortis Bank holds the third. No single party — including Unchained — can move the collateral, rehypothecation is impossible by construction rather than by promise, and the borrower can verify the position on-chain throughout the loan’s life. Required collateral is 200% of principal — the same 50% loan-to-value posture as Ledn’s opening position — with additional collateral or paydown required if the ratio is violated. Housekeeping is published with equal candour: $10 late-payment fee, $15 returned-ACH fee, and a 2% selling fee on any forced liquidation. (Last Verified: July 2026.)

Ledn or Unchained?

Since our two lending reviews will inevitably be read together, the comparison deserves its own ledger. Choose Ledn if you are an individual: personal loans, funding in dollars or USDC in a median 18 hours, no monthly payments, and a Private Wealth tier from $250,000 — against custodial collateral that Ledn undertakes not to rehypothecate, from a Cayman-regulated entity. Choose Unchained if you are borrowing through an entity and want the strongest collateral position in the industry: on-chain verifiability with your own key on the vault, US-licensed counterparties, and zero rehypothecation enforced by cryptography rather than covenant. On price they converge — roughly 12 to 14 percent against Ledn’s published 9.25-to-12 spread — which is precisely why the collateral structure, not the rate, should decide the question.

Inheritance: The Question Serious Wealth Cannot Defer

Most bitcoin estate plans fail for a reason lawyers and wallet vendors each see only half of: the legal documents and the key architecture are drafted by different professionals who never meet. A will that bequeaths “my bitcoin” is worthless if the heirs cannot sign; a multisig setup the heirs can sign is dangerous if the titling contradicts the trust. Unchained’s Inheritance Boot Camp — $4,000 per client, with renewal listed at $4,500 per year — attacks the gap directly in four structured meetings co-delivered with Gannett Wealth Advisors: estate-gap analysis, attorney-network access for the revocable living trust and supporting documents, a complete estate map with final asset titling, and a funded collaborative-custody trust vault, plus two hardware devices and an “In Case I’m Not Here” guide for the family. Signature clients get inheritance coordination included, and Unchained commits to guiding heirs through vault recovery when the time comes. (Last Verified: July 2026.)

For hourly needs outside any package — key replacements, UTXO consolidation, external recovery through Caravan or Sparrow — Concierge Sessions are currently $750 per hour, listed down from $1,200. (Last Verified: July 2026.)

The Honest Limitations

Four caveats belong in any candid assessment. The model is US-centric: the IRA is US-only, lending availability varies by state, and international clients should confirm service coverage before committing. It is not a privacy instrument: Unchained is a regulated US business with know-your-customer obligations; readers optimising for financial privacy should consult our privacy playbook and calibrate expectations. It involves a counterparty, deliberately: the entire point is that Unchained’s key can never move funds alone, but clients who want zero third-party involvement of any kind are simply not the customer — and should weigh honestly whether their solo operational security genuinely clears the bar their net worth requires. And the collaborative model is Bitcoin-only: holders of diversified crypto positions will need separate arrangements for other assets.

The Verdict

For a holder whose Bitcoin funds the lifestyle this publication documents, the arithmetic is not close. A vault is $250 a year; Signature, fully loaded, is $4,500 to $6,000 — priced like an insurance product against the two failure modes that actually destroy Bitcoin fortunes: the lost key and the unplanned estate. The structure is verifiable rather than trusted, the counterparty is US-licensed rather than offshore, and the firm’s zero-lost-bitcoin record is now a decade deep. Set up the vault before the next acquisition, not after. Route the purchase through the trading desk from cold storage. And if there are heirs, treat the Boot Camp as what it is: the least expensive item on the estate-planning invoice that actually determines whether the estate transfers.

Frequently Asked Questions

What is bitcoin collaborative custody?

Collaborative custody secures Bitcoin in a multisignature vault whose keys are split between the holder and a specialist firm. In Unchained’s model, three keys control the vault and any two are required to move funds: the client holds two, Unchained holds one. The client keeps full control — Unchained alone can never move the Bitcoin — while the loss of any single key is no longer catastrophic.

Can Unchained move or freeze my Bitcoin?

No. Unchained holds one key of three, and two are required for any transaction. The company cannot move funds unilaterally, and the client can verify the vault’s contents and key requirements on-chain at any time. Conversely, the client’s two keys mean they can always move funds without Unchained’s participation.

How much does an Unchained vault cost?

A personal vault is $250 per year (Last Verified: July 2026). Guided setup packages run $1,650 to $2,650, and the white-glove Signature tier is $6,000 for the first year, renewing at $4,500, including up to ten vaults, inheritance coordination, and same-day emergency support.

Does Unchained still offer personal bitcoin-backed loans?

No — as of July 2026 Unchained’s lending is a commercial product for businesses, funds, and family offices, with a $150,000 minimum. Individuals seeking a personal Bitcoin-backed loan should evaluate Ledn, whose product this publication has reviewed in detail; collateral for Unchained’s commercial loans sits in a 2-of-3 multisig vault in which the borrower holds a key and rehypothecation is structurally impossible.
