Sygnum vs Fireblocks

Sygnum (dedicated custody) and Fireblocks (stablecoin-custody) serve different corners of the Bitcoin ecosystem, but the question that matters most is the same: who controls the keys? The scores are close — Sygnum at 67/100 (B-) and Fireblocks at 66/100 (C+). When the gap is this narrow, the details matter: custody model, single points of failure, and the fine print on fees.

Where Each Platform Wins

Custody and security — the most heavily weighted category in our methodology at 35% — tilts 23 points toward Sygnum (85 vs. 62). Both platforms carry single-point-of-failure risk, but Sygnum mitigates it more effectively through its Regulated Bank approach. Fireblocks stands out on features (82 vs. 60), reflecting Fireblocks's product breadth and tooling.

The Custody Question

Neither Sygnum nor Fireblocks has fully eliminated single-point-of-failure risk. Sygnum uses Regulated Bank and Fireblocks uses MPC Custody Infrastructure. Both models leave your bitcoin exposed to custodial concentration risk — if that one entity fails, your bitcoin could be locked, seized, or lost. For long-term holders, this is the most important factor to weigh.

Bottom Line

Sygnum edges out Fireblocks by 1 points. It's a close call, and the right choice depends on your specific situation — how much bitcoin you're holding, how often you need access, and whether you prioritize swiss banking license. tokenization services. regulated digital asset bank. over mpc-based custody infrastructure used by 1,800+ institutions. powers stablecoin custody for multiple issuers and custodians. broadest defi connectivity of any infrastructure provider.. Keep in mind these platforms target different audiences — Sygnum is built for swiss, while Fireblocks serves institutions & custodians. One thing to watch with Fireblocks: mpc is not multisig — key shards can be reconstituted by fireblocks. single technology provider dependency. not a custodian itself, but infrastructure. proprietary technology, not open-source..
