BNY Mellon vs Fireblocks: What the Data Shows
BNY Mellon and Fireblocks both operate in the stablecoin-custody space, but they take fundamentally different approaches to how your bitcoin is held. BNY Mellon scores 76/100 (B) versus 66/100 (C+) for Fireblocks. The 10-point spread is meaningful — it usually comes down to custody architecture and fee structure.
Where Each Platform Wins
Custody and security — the most heavily weighted category in our methodology at 35% — tilts 26 points toward BNY Mellon (88 vs. 62). Both platforms carry single-point-of-failure risk, but BNY Mellon mitigates it more effectively through its World's Largest Custodian Bank approach. Fireblocks stands out on features (82 vs. 62), reflecting Fireblocks's product breadth and tooling.
The Custody Question
Neither BNY Mellon nor Fireblocks has fully eliminated single-point-of-failure risk. BNY Mellon uses World's Largest Custodian 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.
