A DeFi project can run for months as pure code and a multisig, but the moment you have to pay a $60K audit, sign a frontend hosting contract, or move treasury into fiat, you need a legal entity that can hold a bank account and sign agreements. For non-US teams, a Wyoming LLC is the cleanest wrapper, and the all-inclusive cost is $397.
Why DeFi projects form a Wyoming LLC
Smart contracts cannot sign legal documents, and a Gnosis Safe cannot pay an invoice in US dollars. That gap is the entire reason a DeFi team forms a company. The protocol lives on-chain; the project around it (the developers, the audits, the frontend, the legal review, the treasury off-ramp) lives in the off-chain world and needs a counterparty that courts, banks, and vendors recognize. A Wyoming LLC is that counterparty.
Wyoming is the natural choice because it built its statutes around exactly this work. It was the first US state to pass digital-asset property law in 2019, the first to charter Special Purpose Depository Institutions for crypto firms, and the first to recognize DAO LLCs under Wyoming Statutes Title 17, Chapter 31 in 2021. In 2024 it added the Decentralized Unincorporated Nonprofit Association (DUNA) under SF50, effective July 1, 2024, giving large non-profit protocol communities a liability shield. You will not use all of these on day one, but they signal a legal environment that already understands what a protocol fee, a token, and a multisig are, instead of treating them as exotic.
For most teams the right starting point is a standard Wyoming LLC, not a DAO LLC. A DAO LLC only makes sense once governance is genuinely on-chain (token-weighted voting through Snapshot or Aragon binding the entity's actions). Early-stage protocols coordinate through a core team, a council, and Discord, so a regular LLC matches reality and avoids unnecessary complexity. You can elect DAO status later by amendment if governance moves fully on-chain.
Wyoming's privacy rules also matter for pseudonymous teams: members and managers do not appear on the public Articles of Organization filed with the Wyoming Secretary of State. Combined with charging-order protection, the LLC gives a distributed, often-anonymous dev team a single legal home that signs contracts, holds the treasury at the legal layer, pays contributors, and files with the IRS, without exposing individual builders' identities on a state website.
There is also a practical maturity argument. Token launches, grant programs, and centralized exchange listings increasingly require a named legal entity behind the protocol before they will engage. Foundations, market makers, and listing desks ask "who is the counterparty?" and "is there limited liability?" before a launch. Having a Wyoming LLC (or, at scale, a DUNA or DAO LLC) already in place turns those conversations from blockers into checkboxes, and it means the entity that signs a market-making agreement or a grant is the same entity that has been filing with the IRS all along, rather than a hastily-formed shell created the week before a listing.
Cost
The package is $397 and it already includes the Wyoming state filing fee. There is no surprise government charge stacked on top. The only recurring cost is the annual registered agent plus Wyoming's annual report license tax, which together run roughly $160 per year for a typical small-treasury entity.
| Item | What it covers | Cost |
|---|---|---|
| Formation package | Wyoming LLC filing (state fee included), EIN via SS-4, operating agreement, registered agent year 1 | $397 one-time |
| ITIN (optional) | Individual Taxpayer ID for the owner, only if personally needed | $297 add-on |
| Registered agent (year 2+) | Required Wyoming in-state agent | ~$100/yr |
| Wyoming annual report | State license tax, min ~$60 for assets under $250K | ~$60/yr |
| Pro-forma 1120 + Form 5472 | Annual IRS filing (DIY or CPA) | $0 DIY / CPA varies |
The ITIN is a separate $297 add-on and most DeFi founders do not need it. The LLC's EIN, not your personal ITIN, is what opens the bank account and goes on IRS filings. You only need an ITIN if you personally have a US tax-filing obligation, which a non-resident pass-through owner usually does not. Budget the $397 once, about $160 each following year, and a CPA fee at tax time if you want the federal filing handled for you.
The exact setup stack for DeFi projects
A DeFi project's stack has two layers that must stay cleanly separated: the on-chain protocol layer and the off-chain company layer. The LLC sits at the boundary. Here is the stack that actually works.
Legal entity: A standard Wyoming LLC under Title 17. The operating agreement is where DeFi-specific clauses go: which wallet addresses the LLC owns, who the multisig signers are and that they act as agents of the LLC (not personal owners), and how treasury decisions are authorized. Getting this in writing is what preserves the liability shield and keeps the multisig from being treated as personal property.
EIN: Obtained via IRS Form SS-4 with no SSN required. This is non-negotiable; every bank, every off-ramp, and every US vendor that pays you will ask for it. Expect roughly 8 to 10 business days for a non-resident SS-4.
Operational fiat bank: Mercury, Relay, or Wise Business (covered in detail below). This account pays your audit firm, frontend hosting, and USD contractor invoices.
Crypto on/off-ramp for treasury: This is the part unique to DeFi. To convert protocol-fee revenue or treasury between stablecoins and bank dollars, the LLC opens a corporate account at a regulated US exchange such as Coinbase Prime or Coinbase Business or Kraken, using the EIN. Per Mercury's own guidance, wires from your business account carry your business name as sender, which is what lets exchanges like Coinbase and Gemini credit the wire to the entity. The exchange handles the actual fiat conversion; your operational bank never has to hold crypto.
Protocol treasury: A Gnosis Safe multisig, documented as owned by the LLC. Keep this strictly separate from the operating bank account. Treasury assets (ETH, USDC, governance tokens) are LLC assets on the balance sheet; operating cash is what pays the bills.
Vendor stack you'll actually pay: Audit firms (Trail of Bits, OpenZeppelin, Spearbit, or Cantina, typically $30K–$150K), frontend hosting (Vercel, Cloudflare, AWS), an RPC provider (Alchemy or Infura), subgraph indexing (The Graph), and securities counsel for any token launch. All of these are USD invoices the LLC signs and pays.
Accounting: Standard bookkeeping (QuickBooks or Xero) for the fiat side, plus a crypto-native sub-ledger such as Cryptio, Bitwave, or Request Finance to track on-chain inflows and outflows in USD at receipt-time exchange rates. You need both because your auditors and your CPA both speak USD, while your revenue arrives in tokens.
Banking for DeFi projects
Banking is the hardest single step for a DeFi project, and the honest framing matters. The constraint is the Money Services Business (MSB) line. US fintech banks cannot serve businesses that operate as crypto exchanges or money transmitters, because their partner banks prohibit banking FinCEN-registered MSBs. A protocol that builds DeFi infrastructure and earns protocol fees is usually not an MSB; a business that swaps customer crypto for fiat may be. Where your project sits on that line determines everything.
Mercury actively courts the category through its Mercury for Web3 product and explicitly supports crypto and web3 companies, with the clear exception of MSBs and exchanges. So a non-MSB DeFi dev shop has a real shot at Mercury, contrary to the old "Mercury rejects DeFi" assumption, but you must present clean, non-MSB operations. Relay is a reasonable parallel application. Wise Business remains the high-acceptance fallback and is excellent for paying distributed developers across borders. Note that none of these hold crypto: per Mercury's documentation you cannot custody coins in the account, you use it to move fiat to and from a regulated exchange.
A note on Custodia Bank: it was purpose-built in Wyoming for digital-asset firms, but as of late 2025 it remains largely dormant after the Federal Reserve denied its master account and the Tenth Circuit upheld that denial. Do not plan your treasury around it; use a regulated exchange (Coinbase, Kraken) for the crypto-to-fiat bridge instead.
| Provider | Best for | Realistic fit |
|---|---|---|
| Mercury (Web3) | Non-MSB dev shops, post-traction protocols | Good if you are clearly not an MSB |
| Relay | Parallel primary fiat application | Moderate, worth applying alongside |
| Wise Business | Cross-border developer payroll, fallback | High acceptance |
| Coinbase Business / Kraken | Crypto-to-fiat off-ramp for treasury | Opened on the EIN, not a checking account |
What reviewers check: a real website, the EIN, the operating agreement naming the entity and its activity, and a clear description that does not read as "exchange" or "money transmitter." Describe yourself as a software development company building protocol infrastructure, because that is accurate, and have the operating agreement back it up.
One more banking realism point: keep your fiat flows boring. Reviewers and ongoing compliance teams react to pattern, not just paperwork. Regular USD payments to known audit firms, hosting providers, and contractors look exactly like a normal software company, which is what keeps an account open. Large, irregular wires to and from exchanges with no supporting documentation are what get accounts frozen or offboarded, even at crypto-friendly providers. So route treasury conversions through one named exchange account on the EIN, retain the trade confirmations, and let the operational account read as a software business. Pairing a fiat bank (Mercury or Relay) for expenses with a separate exchange account for the crypto bridge is not just convenient, it is the structure least likely to trip a reviewer.
Tax handling for DeFi projects
By default a single-member Wyoming LLC is a disregarded pass-through under Treasury Regulation 301.7701-3, so protocol-fee revenue flows to the non-resident owner rather than being taxed at the entity. US federal income tax only reaches income that is Effectively Connected Income (ECI) from a US trade or business. A protocol with no US employees, no US office, and no dependent US agent typically does not generate ECI, so US federal income tax owed is often zero. Validators, oracle providers, and contractors you pay are independent service providers, not your employees, and paying them does not by itself create a US trade or business.
Deductible business expenses for a DeFi project are substantial and worth tracking precisely: smart-contract audits, bug-bounty payouts, securities and regulatory legal fees, frontend hosting and RPC/indexing infrastructure, contractor and core-team payments, exchange and gas fees on treasury operations, and accounting software. Each needs documentation, an invoice or an on-chain transaction record, valued in USD at the receipt-time rate.
Two filings are mandatory regardless of revenue. A foreign-owned single-member LLC must file Form 5472 attached to a pro-forma Form 1120 every year, even with zero income, because capital contributions and owner transactions are themselves reportable. Per the IRS Instructions for Form 5472, filing one without the other, or filing late or incomplete, triggers a $25,000 penalty, with an additional $25,000 for each 30-day period after IRS notice and no cap. This is the single most common and most expensive mistake DeFi founders make, often because they assume crypto-denominated revenue is somehow outside the system. It is not.
Crypto-specific reporting is also tightening. The IRS finalized broker rules requiring Form 1099-DA for digital-asset sales: gross proceeds for transactions on or after January 1, 2025, and adjusted basis for covered assets on or after January 1, 2026, per the IRS final broker regulations. Custodial exchanges where your LLC off-ramps treasury will issue these forms against your EIN, so reconcile them. The separate 1099-K threshold reverted to more than $20,000 and 200 transactions under the One Big Beautiful Bill Act (not the once-planned $600), relevant if you take card-based fiat payments. None of this changes your home-country obligations: most countries tax worldwide income, so a local CPA still has to sign off on how the protocol revenue is taxed where you live.
Step-by-step
- Confirm structure. Choose a standard Wyoming LLC unless your governance is already fully on-chain and binding, in which case consider a DAO LLC election. Most projects start standard.
- File the Articles of Organization with the Wyoming Secretary of State under Title 17. With the $397 package the state fee is included and formation completes in about 24 hours. Members stay off the public record.
- Adopt a DeFi-specific operating agreement. Name the LLC's wallet addresses, list multisig signers as agents of the entity, and define how treasury and contract decisions are authorized.
- Obtain the EIN via Form SS-4 (no SSN needed), roughly 8 to 10 business days. This unlocks banking, the exchange account, and IRS filings.
- Open the operational fiat account. Apply to Mercury (Web3) and Relay in parallel; keep Wise Business ready as a high-acceptance fallback for cross-border dev pay.
- Open the crypto off-ramp. Set up a Coinbase Business or Kraken corporate account on the EIN to convert treasury between stablecoins and bank dollars. Your fiat bank never holds crypto.
- Stand up the treasury multisig. Deploy or document the Gnosis Safe as an LLC-owned asset, separate from operating cash.
- Connect accounting. Use QuickBooks or Xero for fiat and Cryptio or Bitwave for the on-chain sub-ledger, recording every inflow in USD at receipt-time rates.
- Pay vendors through the LLC. Sign and pay audits, hosting, RPC, indexing, and legal as deductible expenses with proper invoices.
- File annually. Submit Form 5472 with a pro-forma 1120 by the deadline, reconcile any 1099-DA from your exchange, file the Wyoming annual report, and consult your home-country CPA.
Common mistakes DeFi projects make
- Skipping Form 5472 because revenue is crypto-denominated. It is still mandatory at $0 revenue, and the penalty is $25,000 per missed year. This is the costliest error in the category.
- Forming a DAO LLC on day one when governance is still off-chain. It adds legal complexity with no benefit; start standard and convert later if needed.
- Holding the multisig under personal names instead of LLC ownership. This collapses the liability shield, because the asset is no longer the company's.
- Not documenting signers and wallet addresses in the operating agreement. Without this, the legal line between protocol and personal control is undefined.
- Treating Mercury as a guaranteed yes or a guaranteed no. It now serves non-MSB web3 companies through Mercury for Web3, but anything resembling an exchange or money transmitter will be declined. Apply to Relay in parallel and keep Wise as a fallback.
- Planning treasury around Custodia Bank, which is largely dormant after losing its Fed master account. Use a regulated exchange for the fiat bridge.
- Mixing personal wallets with LLC wallets, which creates an unwinnable legal and tax reconciliation problem and undermines pass-through treatment.
- Assuming Wyoming formation shields a token launch from US securities law. It does not; securities law applies regardless of state of formation, so engage securities counsel before any launch.
