Crypto companies do not fail KYC because they “use blockchain.” They fail because the story on the application does not match the company, the wallets or the website.
If you are searching how to open a US business bank account for a crypto company, you usually need three boring objects and one honest sentence: a real LLC, an EIN (Employer Identification Number — the company’s US tax ID), a matching US mailing address, and a business description that a human analyst can repeat without wincing.
At OtoCo, we assemble that stack for wallet-native teams: Wyoming or Delaware LLCs, EIN without an SSN, virtual mailing, and Mercury application prep. We are not a bank. Approval is never guaranteed. This guide is the crypto-specific banking path — what banks actually ask, how the Mercury flow works remotely, and where founders improvise themselves into a decline.
Short answer: Form the US LLC first, get the EIN, put a bankable address on the file, then apply with a clear description of what the company does (software, services, treasury ops — not “Web3 stuff”). OtoCo’s Mercury add-on is application prep and submit only (~$299). The bank decides. Non-residents can do this remotely without an SSN when the package is coherent.
Why crypto companies get extra questions
Banks and fintechs are in the business of not onboarding unexplained money. A crypto company looks like unexplained money until you show:
- A legal person (the LLC) that can own the account.
- Beneficial owners who match formation documents.
- A source-of-funds story that is not “the wallet did it.”
- A product that is legal to bank — software, advisory, marketplace services — versus activities that look like unlicensed money transmission or token issuance from the operating account.
Think of the LLC as the shop. The bank account is the till. The wallets are the warehouse. If the till is in your personal name and the warehouse is a Safe nobody documented, the inspector does not care how elegant the smart contracts are.
The non-resident remote stack (not crypto-specific) is here: US business bank account as a non-resident. The classic foreign-founder playbook: US LLC + bank account for non-US founders. This post is the crypto overlay.
What you need before you apply
- US LLC — Instant Series or Standalone. Some legacy banks prefer Standalone because they can search the state registry. Fintechs often accept Instant if the rest of the file is clean. Shape guide: Onchain Standalone LLCs.
- EIN — you do not need employees to need one. Non-US path: EIN without an SSN. OtoCo EIN add-on is ~$189 once.
- US business address — registered agent is the legal inbox; banks often want a mailing address they can put on the application. OtoCo virtual mailing is ~$249/yr.
- Operating agreement that names members/managers and, for crypto teams, should not contradict who controls company wallets.
- An honest activity description — “We build wallet software and invoice in USD” beats “DeFi / NFTs / maybe a token.”

The Mercury flow (what OtoCo actually does)
Mercury is a US business banking fintech many remote founders use. OtoCo can prepare and submit an application with your formation packet.
- Form the LLC (Wyoming or Delaware; Instant or Standalone).
- Add EIN and virtual mailing if you do not already have a bankable address.
- Pay Mercury application support (~$299) — prep and submit only.
- OtoCo / Genco helps assemble docs so names, address and EIN tell one story.
- Mercury underwrites. They may ask follow-ups. They may decline.
OtoCo is not a bank. Mercury approval is not guaranteed. A decline does not mean the LLC is fake — it means that institution’s appetite did not match your file. Product walkthrough: Genco + Mercury.
Company-in-a-Box bundles formation + stack (Instant ~$836 / Standalone ~$1,036 on current list prices) when you do not want to à-la-carte the same pieces.
Remote, no SSN: yes — with matching docs
Non-US founders can own a US LLC and apply for business banking without flying in and without a Social Security Number. The EIN is the company tax ID; the SSN is a personal US number. They are not interchangeable. You still need KYC on beneficial owners (passport, etc.) as the bank requires.
What kills remote applications:
- Address on the bank form ≠ address on formation / EIN / website.
- Personal wallet used as “company treasury” with no paper trail.
- Token-issuance language in the business description when you are applying as a software studio.
- PO Box / virtual mail that the bank’s rules reject (some declines cite address type). Have a backup plan; OtoCo’s integration is Mercury-first, not a universal bank menu.
What to tell the bank (without lying)
Write the company like a shop, not a manifesto.
- Who the customer is.
- What you sell (SaaS, services, licensing).
- How you get paid (invoice, card, stablecoins converted to USD).
- What you will use the account for (operating expenses, payroll/contractors, receiving customer funds).
- What you will not use it for if that is true (retail crypto exchange, mixing, unhosted-wallet transmission as a service).
If you are preparing a token launch, do not pretend the operating company is a lemonade stand. Structure the entity, then get counsel on the offer. Banking the studio is different from banking an issuer. Sequence: LLC for a token launch.
After the account is open
- Pay company bills from the company account.
- Keep personal wallets and company wallets apart.
- If you offramp USDC, document it as company funds.
- Foreign-owned disregarded LLCs may still need Form 5472 even at $0 tax. Pass-through in plain English.
FAQ
Can a crypto company get a US business bank account?
Often yes, if it is an operating company with a clear product, an LLC, an EIN and matching docs. Pure token-issuance or VASP-like activity is a different (harder) underwriting story.
Do I need to visit the US?
Not for OtoCo formation, EIN-without-SSN, address and Mercury prep. The bank may still ask for video KYC.
Is Mercury the only option?
It is the path OtoCo prepares. Other fintechs and banks exist; we do not control their credit decisions.
Build the file, then apply
A US business bank account for a crypto company is not a secret product. It is a coherent company: wrapper, tax ID, address, and a sentence a banker can understand.
Form that company at otoco.io — then add EIN, mailing and Mercury prep when you are ready for USD rails.
