  • Name: Unchained
  • URL: https://www.unchained.com/
  • Category: Bitcoin collaborative-custody infrastructure / treasury and inheritance control plane / bitcoin financial-services platform
  • Tags: bitcoin-ecosystem
  • Summary: Unchained is a Bitcoin financial-services platform built around collaborative multisig custody rather than exchange custody or fully solo self-custody. Its public materials show a product surface spanning personal and business vaults, direct-to-cold-storage trading, bitcoin-backed loans, key-controlled Bitcoin IRAs, inheritance planning, and guided security services, so it is better cataloged as a collaborative-custody and bitcoin-finance control plane than as a simple wallet, lender, or brokerage.
  • What it does:
    • Offers 2-of-3 multisig vaults in which clients hold two keys and Unchained holds one backup key, for both individuals and businesses
    • Provides trading that settles bitcoin directly into cold-storage vaults rather than requiring exchange withdrawal flows
    • Offers bitcoin-backed commercial loans where customer collateral remains in multisig and can be verified on-chain with a key the borrower controls
    • Offers Bitcoin IRA products where customers hold real bitcoin in multisig cold storage while keeping tax-advantaged retirement-account structure
    • Provides inheritance planning, executor guidance, beneficiary structures, trust-oriented custody setups, and family/heir coordination tools
    • Sells high-touch advisory, onboarding, and security-review services for customers who want expert help rather than pure self-serve software
  • Key claims:
    • The homepage defines Unchained as a place to “buy, protect, borrow against, and retire with bitcoin while holding your own keys the whole time,” which captures the broad financial-services surface better than any single product page
    • The vaults page says collaborative custody is meant to remove single points of failure while preserving user control, with two of three keys required to spend and Unchained unable to move funds unilaterally
    • The business-vaults page shows that Unchained is not just a consumer custody brand: it also supports treasury governance, team permissions, key rotation, and organization-specific workflows
    • The loans page emphasizes “zero rehypothecation” and on-chain verification using a customer-controlled key, which is a meaningful architectural distinction from many crypto lenders
    • The Bitcoin IRA page repeatedly stresses that the IRA holds real on-chain bitcoin under multisig key control rather than paper claims, showing Unchained extending collaborative custody into retirement-account infrastructure
    • The inheritance page is especially revealing: Unchained treats inheritance as a combined legal-title, executor-process, beneficiary, and key-access problem, which supports cataloging it as a broader custody-control-plane platform rather than only a multisig vault vendor
  • Whitepaper: No canonical Unchained whitepaper or litepaper surfaced in this pass. The clearest current sources of truth are the official site and product pages for vaults, inheritance, loans, IRAs, trading, and business custody; see ../whitepapers/unchained-primary-sources-2026-04-28.md.

  • Strongest comparison points: casa, bitkey, and fireblocks.

  • Useful whenever you hold your keys is doing a lot of work while the real leverage still sits in recovery, collateral workflow, retirement wrappers, and trading-settlement defaults.
