Custody Integrations — Beyond the Basics

Most teams start with the security checklist: multi-sig, cold storage, insurance. That's table stakes. The real complexity shows up when you try to actually use it. We've worked with teams across three custody models, and here's what matters beyond the security specs:

— Integration depth determines user experience. Self-custody gives users control but pushes complexity onto you. Custodial solutions simplify onboarding but limit flexibility. Hybrid models balance both, but your choice shapes every user flow and your UI. Custody design matters.

— Compliance frameworks vary dramatically. Institutional custodians come with audit trails and regulatory reporting built-in. MPC solutions offer technical elegance but may need custom compliance layers. Self-custody puts the entire audit burden on your infrastructure.

— Insurance and liability models matter. Who’s responsible when things go wrong? Some custodians cover losses, others provide insurance options, many push liability back to you. This isn't just legal — it affects how you design risk management and customer communication.

— Operational complexity compounds over time. Key rotation, backup recovery, multi-jurisdiction support, and integration testing — the decisions you make today become operational reality your team lives with for years.

At FinHarbor, we've designed our platform to support all three models. Teams can start with hybrid, or go full self-custody — without rebuilding their core infrastructure.
