Unchained vs Sygnum

Unchained and Sygnum both operate in the dedicated custody space, but they take fundamentally different approaches to how your bitcoin is held. Unchained scores 85/100 (A-) versus 67/100 (B-) for Sygnum. The 18-point spread is meaningful — it usually comes down to custody architecture and fee structure.

Where Each Platform Wins

On custody and security, these two are within 3 points of each other (88 vs. 85). When custody scores are this close, look at the specifics: key management model, insurance coverage, and whether either platform has a single point of failure. On fees, Unchained wins by 23 points. Unchained charges $250/yr + trading compared to Custom at Sygnum. Over a multi-year holding period, fee differences compound — a point worth considering for long-term accumulators. Unchained's strongest advantage is in features (85 vs. 60), where Unchained's product breadth and tooling makes a measurable difference.

The Custody Question

Here's the key difference: Unchained has no single point of failure (Collaborative Multisig), while Sygnum does (Regulated Bank). This matters because a single-point-of-failure model means one compromised entity — whether through a hack, insolvency, or government action — could result in total loss of funds. History has proven this risk is not theoretical. FTX, Celsius, and BlockFi all represented single points of failure for their users.
