Unchained
Multisig Bitcoin IRA with real key control
Our Verdict
The closest thing to true self-custody inside a retirement account. Unchained uses a 2-of-3 multisig model where you hold one key, Unchained holds one, and a third-party key agent holds one. No single party can move your Bitcoin alone. This is a fundamentally different custody model than every other Bitcoin IRA - Swan uses collaborative multisig but Unchained pioneered the approach and has the longest track record with it. The trade-offs: it is the most expensive option (setup fees, annual fees, and trading fees all add up), requires real technical comfort with multisig, and the onboarding process is heavier than competitors. For holders with significant amounts who understand multisig and want maximum sovereignty within IRA constraints, Unchained is the best option. For everyone else, Swan's simpler collaborative model is probably sufficient.
What we like
- True 2-of-3 multisig - you hold a key, Unchained holds one, third-party key agent holds one
- No single party can move your Bitcoin - strongest custody model in the IRA space
- Pioneered multisig IRA custody - longest operational track record
- Bitcoin-only focus, no altcoin distractions
- Transparent about custody architecture and key management
- Extensive educational resources on multisig and inheritance planning
What could be better
- Most expensive Bitcoin IRA - setup fees, annual custody fees, and trading fees
- Requires meaningful technical comfort with multisig concepts
- Heavier onboarding process than competitors (hardware wallet setup, key ceremony)
- Higher minimums than iTrustCapital
- Smaller company than Fidelity or Schwab - less institutional backing
- The complexity is overkill for smaller IRA balances
