What Technical and Compliance Requirements Shape Crypto Banking Platform Development?

Building a crypto banking platform in the US requires integrating crypto infrastructure with regulated financial operations, including custody decisions, ledger design, KYC/KYB, transaction monitoring, and fiat on/off-ramp logic. Unlike simple wallet apps, these platforms must handle dual ledgers, bank integrations, suspicious activity review, and money-transmitter compliance under FinCEN rules. The real complexity lies not in user-facing features but in underlying compliance-aware architecture that enables safe scaling.
