Why We Chose FBO Accounts Over Direct Banking Charters

When we started Nano Wallet, one of the first major decisions was how to hold customer funds. The choice between obtaining a direct banking charter and using For Benefit Of (FBO) accounts shaped everything from our regulatory obligations to our product roadmap.

What Is an FBO Account?

An FBO account is a pooled account held at an FDIC-insured bank — in our case, Column N.A. — where the bank holds funds on behalf of our customers. Each customer's balance is tracked in our internal ledger, but the actual dollars sit in Column's vault. This structure means customer deposits are eligible for FDIC insurance up to $250,000 per depositor, because Column is the insured institution.

Why Not a Banking Charter?

A de novo banking charter takes 18 to 24 months to obtain, requires $20 million or more in initial capital, and subjects the company to direct examination by the OCC or a state banking regulator. For an early-stage fintech, this timeline and capital requirement would have delayed our launch by two years.

More importantly, a charter changes the nature of the business. Chartered banks must maintain capital adequacy ratios, submit to regular stress tests, and comply with the Community Reinvestment Act. These obligations are appropriate for institutions that lend money, but Nano Wallet is a payments and savings platform — we don't originate loans.

The FBO Advantage

The FBO model lets us focus on what we do best: building a seamless user experience for holding, converting, and transferring digital dollars. Column handles the banking infrastructure — ACH processing, wire transfers, and regulatory reporting to the Federal Reserve. We handle the product layer — the dashboard, the conversion engine, the compliance monitoring.

This separation of concerns also reduces our regulatory surface area. We register with FinCEN as a Money Services Business and obtain state money transmitter licenses where required, but we avoid the full weight of bank regulation. Our compliance team of six people can manage our obligations effectively, whereas a chartered bank of similar size would need 15 to 20 compliance staff.

Trade-offs

The FBO model isn't without drawbacks. We depend on Column for settlement speed — if their ACH processing is slow, our users feel it. We also can't set our own interest rates on deposits; the yield we offer comes from Column's investment of pooled funds, minus their margin.

We've mitigated the first issue by maintaining redundant banking relationships and building a queue system that can reroute transactions if one partner experiences downtime. For the yield question, we supplement Column's base rate with returns from our USDC treasury management through Bridge, which is how we offer competitive APY on stablecoin balances.

Looking Ahead

As we scale, we periodically reassess the charter question. At some point, the economics may favor bringing banking in-house. But for now, the FBO model gives us the regulatory coverage our customers need, the FDIC insurance they expect, and the operational flexibility to ship product improvements every two weeks instead of every two quarters.
