Frequently Asked Questions
What is the minimum balance at US Fintech Platforms (Mercury-class)?
No minimum deposit. Falling below the threshold typically triggers a monthly fee rather than closure, but we structure your cash plan to stay comfortably above it.
Can I open the account remotely?
Fully remote for US LLCs. Where in-person signing is required, GoldenKey schedules a single consolidated visit covering the bank meeting and document signing.
Which currencies can the account hold?
USD. Multi-currency capability matters more than headline fees for international structures — conversion spreads are usually the hidden cost.
Why do banks reject offshore-linked applications?
The three killers are unclear source of funds, vague business descriptions and mismatched jurisdictions. A pre-audited compliance file addressing all three is exactly what GoldenKey builds before any application is lodged.
How long until the account is live?
Well-prepared files at receptive institutions typically approve in one to six weeks depending on profile complexity. Poorly prepared files take months — or die silently in compliance.
