An MLM smart contract is a multi-level marketing plan written into a contract, often on BNB Smart Chain (BSC). Users pay BNB or a token to join, and the contract splits each new payment among the people above them in a referral tree. In nearly every version on the market, the only source of payouts is money from new recruits, which is the defining feature of a pyramid scheme, so these contracts carry serious legal risk for anyone who builds, promotes or joins them.
How a smart contract MLM works
The designs vary, but most share four parts:
- Entry payment. A user sends a fixed amount of BNB or a BEP-20 token to the contract and registers the address of the person who referred them.
- Placement. The contract places the user in a structure, commonly a single-level tree, a binary tree, or a "matrix" with a fixed number of slots per level. Promoters label matrix plans by their shape: "3x1" means three slots on one level, and "2x2" means two slots on each of two levels.
- Automatic payout. The contract splits the payment at once among addresses several levels above the new user. Many contracts use "spillover": each member has a fixed number of places directly below them, and when those places are full, the contract places new recruits lower in the tree, under other members, and the members above still earn from them.
- Level upgrades. Users pay again to unlock higher levels with bigger payouts. When a user has not upgraded, the contract often skips that user and sends the payout to the next qualified member higher in the tree.
The contract usually sells no product, or a product with little real value, so money flows from later members to earlier members, and anyone can verify that flow on the blockchain.
Why BSC MLM contracts became common
Low fees on BSC make small entry payments and many tiny payouts affordable. At the 0.05 gwei minimum gas price set in October 2025, each payout costs a tiny fraction of a cent. BSC is EVM-compatible, so promoters copy templates written for Ethereum, and it has a large retail user base that promoters reach through social media.
Promoters often call the contracts "decentralized", "unstoppable" or "no admin", suggesting that nobody is responsible because the code runs on its own, but courts and regulators do not accept that argument.
The legal position of an MLM smart contract
Regulators look at the economic substance of a scheme, not at the technology that runs it.
- United States. The FTC treats a compensation plan as a pyramid scheme when it rewards recruiting more than sales to real customers. The FTC's business guidance on multi-level marketing says courts look at how a company operates, not only at its written policies. When participants invest and expect profits from other people's efforts, the SEC can also treat the scheme as an unregistered securities offering.
- India. The Prize Chits and Money Circulation Schemes (Banning) Act prohibits money-circulation schemes, and the Consumer Protection (Direct Selling) Rules, 2021 ban pyramid schemes and money circulation in direct selling.
- European Union. The Unfair Commercial Practices Directive lists pyramid promotional schemes among the practices banned in all circumstances.
- Elsewhere. Pyramid schemes are illegal in most countries.
Liability can reach the people who design the plan, write and deploy the contract, run the website and promote the scheme. An immutable contract gives no defense and can make the harm worse, because nobody can refund the victims or shut the scheme down.
The Forsage case
In August 2022 the SEC charged 11 people over Forsage, a smart contract MLM that, according to the SEC, ran on the Ethereum, Tron and Binance blockchains. The SEC said Forsage raised more than $300 million from millions of retail investors, that investors earned mainly by recruiting others, and that earlier investors were paid with money from newer ones. The SEC charged four founders and seven US promoters.
Regulators had warned about Forsage before the SEC case. The Philippine SEC issued a cease-and-desist order in September 2020, and the Montana securities regulator issued one in March 2021. The SEC said the founders kept promoting the scheme after both orders.
Red flags in an MLM smart contract
| Red flag | Why it matters |
|---|---|
| Payouts come only from new members' payments | Payouts stop once recruitment slows |
| No real product, or a product nobody would buy on its own | The product serves only to disguise payments for recruitment |
| Promised or implied returns, such as "2x your BNB" or "passive income" | Points to an investment contract and misleading marketing |
| Paid level upgrades to keep earning | Takes more money from existing members |
| "No admin, can't be stopped" marketing | Tries to shift responsibility away from the founders, which regulators reject |
| Anonymous founders and pressure to join early | Early members profit at the expense of later ones |
| Hidden owner functions or withdrawal backdoors | Many such contracts also let the deployer take the funds |
The arithmetic is simple. In a structure where each member needs two recruits, each level doubles, so level 30 alone needs 2 to the power of 30 members, which is more than one billion people. Recruitment stops long before that level, and most people who join late lose money.
Requests to build an MLM smart contract
Developers who knowingly build fraudulent schemes can face civil and criminal liability, and reputable auditors decline to certify these contracts. A client's claim that the plan is legal because "everything is on-chain" does not change the legal analysis. A developer who receives such a request can decline it or get legal advice before going further.

Lawful alternatives for growth
- Single-level referral programs pay a fee or a credit when a referred user makes a real purchase, funded from the product's revenue.
- Affiliate programs pay a published commission on real sales to end customers.
- Usage-based rewards, such as fee discounts or loyalty points, reward use of the product instead of recruitment.
These programs can run on-chain, for example as a contract that records referral codes and pays a share of protocol fees. In a lawful program, the money comes from customers who use a product, not from new members' entry fees.

Frequently asked questions
Is a smart contract MLM legal if it is fully decentralized?
Decentralization does not change the legal analysis. If payouts depend on recruiting rather than on sales of real products to real customers, the plan is likely a pyramid scheme, and the people who created and promoted it can be held responsible.
Why do MLM smart contracts collapse?
Payouts depend on a growing stream of new members. Recruitment cannot grow forever, so later members stop receiving payouts once it slows, and most of them lose money.
How can I check a BSC MLM contract?
Read the verified source code on BscScan and trace where incoming payments go. Look for withdrawal functions that only the owner can call, and check whether any revenue comes from outside new deposits, because a contract with no outside revenue works as a pyramid.
Can a referral program on BSC be legitimate?
Yes. A referral program is legitimate when rewards come from real product revenue and are paid for real purchases or usage, and participants should not have to buy in to earn.
