Casa (dedicated custody) and Trezor (hardware) serve different corners of the Bitcoin ecosystem, but the question that matters most is the same: who controls the keys? Casa scores 82/100 (A-) versus 71/100 (B-) for Trezor. The 11-point spread is meaningful — it usually comes down to custody architecture and fee structure.
Custody and security — the most heavily weighted category in our methodology at 35% — tilts 15 points toward Casa (90 vs. 75). On fees, Trezor wins by 5 points. Trezor charges ~$70 - $180 compared to $30 - $250/yr at Casa. Over a multi-year holding period, fee differences compound — a point worth considering for long-term accumulators. Casa's strongest advantage is in features (80 vs. 60), where Casa's product breadth and tooling makes a measurable difference.
Both Casa and Trezor have addressed the single-point-of-failure problem — neither relies on a single custodian or a single set of keys. That puts both platforms ahead of the majority of the industry. The difference comes down to implementation: Casa uses Collaborative Multisig, while Trezor uses Hardware Wallet.
