Series LLC vs Standalone LLC: Which Does Your Crypto Project Need?

Crypto teams hear “Series LLC” and “Standalone LLC” and assume one is a toy and the other is the real company.

That is the wrong fork.

A Series LLC is a legal structure: a master LLC that can host separate series, each meant to keep its own assets and liabilities if you maintain them correctly — like compartments on a legal motherboard. A Standalone LLC is the traditional form created by a filing event, meaning the state registry receives and accepts formation documents for your company.

On OtoCo, Instant LLCs are Series. Standalone LLCs are state-filed independents in Wyoming or Delaware. Both are real US limited liability companies. Both can be owned from a wallet. They are optimised for different counterparties.

We pioneered instant onchain Series LLCs, then added Standalone filings so the legal wrapper could keep pace with banks, exchanges and investors who still want a registry lookup. This guide answers the product question: which does your crypto project need?

Short answer: Start with an Instant Series LLC when you need a legal face fast — invoices, grants, contractor agreements, a treasury container. Choose a Standalone LLC when a bank, exchange, investor or legacy provider wants to see your company in the Wyoming or Delaware public registry. You are not “more legal” in Standalone. You are more look-up-able.

What a Series LLC actually is (plain English)

An LLC, or Limited Liability Company, is a legal wrapper with its own name, rules and liability boundary.

A Series LLC lets one master LLC spawn protected series. Each series can have its own name, members, assets and (if maintained correctly) its own liability wall. The master is the building. Each series is a lockable unit. Mix the mail and the locks fail.

On OtoCo, an Instant LLC is typically a protected series under our master LLC backbone. You connect a wallet, name the company, and it can go live in seconds. There is generally no individual listing for that series in the state registry. You still get limited liability separation and digital management — including an onchain ownership record.

That is not a fake company. It is a different recognition layer. Docs version: OtoCo’s Series explainer in product documentation; category version: what an onchain LLC means.

What a Standalone LLC actually is

A Standalone LLC is an independent state-filed company. After you pay and submit formation details, OtoCo files with Wyoming or Delaware. Confirmation is typically 24–48 hours. The company appears in the public registry. Then it is minted onchain so your wallet still holds the digital proof.

List price band: from ~$299/yr versus Instant from ~$99/yr. You also need member/manager details at filing — you cannot spin a Standalone from a wallet nickname alone. OtoCo still provides the registered agent as part of the annual path.

Series vs Standalone: side-by-side for crypto teams

When a Series / Instant LLC is enough

Choose Instant if:

1. You need a company this week so a grant, contractor or marketplace can pay an entity instead of your personal name.
2. You are outside the US and the next 90 days are EIN + fintech banking, not a Bank of America branch visit.
3. Your counterparties are crypto-native — they care that a legal person exists, not that they can grep a secretary-of-state search.
4. You want the lowest keep-alive cost whilst you test the business.

Instant is how we bring what was reserved for the ultra-wealthy within everybody’s reach: a real wrapper without a six-week law-firm ritual.

When a Standalone LLC is the better crypto fit

Choose Standalone if:

1. A bank, credit union or processor asked you to “look it up on the Delaware / Wyoming website.”
2. An exchange, market maker or auditor wants a Certificate of Formation in your company’s name, not a series-of-master story.
3. US investors or enterprise procurement treat Series LLCs as unfamiliar (recognition varies by state — California is the usual cautionary example).
4. You operate, own property or expect litigation in a state that treats Series inconsistently.
5. You are a US-resident operator who wants the conventional filing from day one.

If the next email in your inbox is a KYC analyst, Standalone is often cheaper than arguing Series theory under a deadline.

Banks, exchanges, investors: who asks for what

1. Fintechs (e.g. Mercury) — care about EIN, matching ownership docs, a US address story and a clear business description. Instant can work. Vague “Web3 stuff” fails in either shape. Banking playbook: US LLC + bank account for non-US founders.
2. Legacy banks — more likely to want a registry-visible Standalone.
3. Exchanges / listing partners — often want formation docs they can map to a single legal person. Standalone reduces explanation. Still not a securities-law shield.
4. US VCs — often Delaware, often conventional filings, later C-Corp. Series is rarely the fundraising default.

State still matters: Wyoming vs Delaware for crypto founders.

Can you convert Instant to Standalone?

There is no magic “upgrade button” that turns a series into a historically filed company with the same formation date.

In practice you:

1. Form a new Standalone LLC in Wyoming or Delaware.
2. Assign IP, domains, contracts and treasury control into the new company (novations, wallet/Safe controller updates, pledge documents where needed).
3. Keep the Instant entity in good standing until the migration is done — or wind it down once the trail is clean.
4. Tell banks and counterparties the new legal person is the contracting party.

Treat it like moving house, not like renaming a folder. If regulated token activity is involved, get advice before you shuffle assets. Same hygiene we recommend after RMI migrations: move wallets, agreements and contracts on purpose.

Mistakes crypto teams make

1. Assuming Instant is not a “real LLC”

It is a Series LLC. The job is recognition, not metaphysical legality.

2. Paying for Standalone as a personality upgrade

If nobody needs a registry hit, you paid extra for theatre.

3. Mixing series assets like they were one wallet

The liability wall depends on maintenance: separate records, separate treasuries, no sloppy commingling.

4. Forming Standalone and leaving the treasury in a personal wallet

Shape does not move assets. You still have to assign them. Token sequence: LLC for a token launch.

Pick the recognition layer, then form

Your crypto project needs the wrapper your next counterparty can verify. Instant Series for speed. Standalone for registry fluency. Both live on OtoCo, both manageable from a wallet.

Form your company at otoco.io — toggle Instant or Standalone, Wyoming or Delaware, and keep building.
