Fit follows the custody model, not the brand.
You hold most keys, the provider holds one, and no single party can move funds alone.
Separate institutions each hold a key under their own ceremony; no one of them can move funds.
Unchained (dedicated custody) and BlackRock BUIDL (tokenized-treasury) serve different corners of the Bitcoin ecosystem, but the question that matters most is the same: who controls the keys? The scores are close — Unchained at 85/100 (A-) and BlackRock BUIDL at 80/100 (B+). When the gap is this narrow, the details matter: custody model, single points of failure, and the fine print on fees.
