Onramp (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? In our scoring model, Onramp holds a commanding lead at 90/100 (A) compared to Fireblocks at 66/100 (C+). That 24-point gap reflects real, measurable differences in how each platform handles custody, fees, and transparency.
Custody and security — the most heavily weighted category in our methodology at 35% — tilts 32 points toward Onramp (94 vs. 62). Onramp eliminates single points of failure in its custody architecture, while Fireblocks relies on a model where one compromised entity could put your bitcoin at risk. On fees, Onramp wins by 24 points. Onramp charges $250/mo compared to Custom SaaS pricing at Fireblocks. Over a multi-year holding period, fee differences compound — a point worth considering for long-term accumulators.
Here's the key difference: Onramp has no single point of failure (Multi-Institution Custody), while Fireblocks does (MPC Custody Infrastructure). 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.
Onramp is the clear choice here, outscoring Fireblocks by 24 points across our six-category methodology. Keep in mind these platforms target different audiences — Onramp is built for institutions & hnw, 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.. The data speaks for itself — but always verify our methodology and do your own due diligence before moving bitcoin to any platform.
Based on our six-category scoring methodology, Onramp scores higher at 90/100 compared to 66/100. The biggest differentiator is custody security, which accounts for 35% of the overall score. However, the right choice depends on your individual needs — review the category breakdown above.
