Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsBefore sending funds to an Ethereum token presale, verify who is offering it, what the token actually entitles you to, how the sale and token contracts work, and what happens if the project fails. Treat the project’s claims as claims until you can confirm them independently. A whitepaper, an audit, or a securities-related filing does not establish that an investment is safe.
This is a general due-diligence framework, not a verdict on a particular sale. No issuer, contract address, jurisdiction, or investor location is specified, so none can be independently checked here.
Start with the actual issuer and offering
Find the project’s primary website and original sale documents independently. Do not rely on a link in an unsolicited message, advertisement, or social post: scammers may impersonate real projects or create convincing fake materials.
Record the information that identifies the offer, not just the token’s marketing name:

- Trusted by 6 million users worldwide - buy, sell, swap, stake, and spend cryptocurrency directly. The secure offline storage wallet designed for how people actually use crypto wallets
- The legal entity making the offer and the people responsible for it.
- The entity’s jurisdiction and the countries or regions where the sale is offered.
- The sale dates, payment recipient, accepted payment methods, and exact token name.
- The blockchain network and the contract addresses the project says are involved.
Check whether the sale documents, website, and payment instructions consistently identify the same entity and offer. If the project does not clearly name an accountable issuer or explain who receives the funds, you cannot assess its claims on equal terms with a transparent offering.
Work out what you are buying and what the money funds
Read the whitepaper, business plan, roadmap, and token terms together. Marketing language such as “utility,” “governance,” or “community token” does not by itself explain what a buyer can do or claim. Look for specific rights and practical limits.
- Use of proceeds: What will the contributed funds pay for? Are spending plans concrete enough to assess, and who controls the funds?
- Token rights: Does holding the token grant access, voting rights, a claim on revenue, or something else? Are those rights enforceable or dependent on the project’s continued operation?
- Allocation: How much is allocated to the team, founders, early backers, and public buyers? Are insider tokens subject to vesting or lockups?
- Refunds and delays: Under what conditions, if any, can buyers receive refunds? What happens if a launch, product, or other milestone is delayed or abandoned?
- Resale and liquidity: Are there transfer restrictions, lockups, or other limits on reselling? A planned exchange listing is not the same as a guarantee that a market will exist.
The SEC Investor.gov’s Investor Bulletin: Initial Coin Offerings advises investors to ask how contributed money will be used, what rights a token provides, and how refunds and resale work. If the documents avoid those questions, do not fill the gaps with assumptions drawn from promotional posts.
Check the legal disclosures in the right jurisdiction
Ask whether the issuer says the offering is registered or relies on an exemption, and what that means for who may participate. If it claims to have made a filing, verify the filing independently. A filing is not the same as SEC approval or a recommendation of the offering.

For U.S. readers, the SEC’s educational page Transactions Involving Crypto Assets, dated April 22, 2026 and last reviewed or updated April 29, 2026, explains that a crypto asset may be offered through a transaction involving an investment contract even if the asset itself is not a security. Classification depends on the facts of the transaction. That U.S. framing does not determine the law in another country or classify an unnamed presale. For a specific offer, consult a qualified legal professional familiar with the relevant jurisdictions.
Verify the contract and its administrator powers
Locate the contract address in original project documentation, then compare it with the address shown on a blockchain explorer for the stated network. A token’s name or symbol is not enough to identify it; similarly named assets can exist. Confirm that you are looking at the intended network and distinguish the token contract from any separate sale contract.
Where source code is published, check that the verified code corresponds to the contract address you are examining. Then investigate who can change how the contracts behave. Depending on the design, relevant powers may include minting tokens, pausing transfers, blacklisting addresses, changing fees, upgrading code, or withdrawing sale funds. Compare those powers with what the offering documents disclose and explain.
The SEC Investor Bulletin specifically recommends asking whether the blockchain is open and public, whether code has been published, and whether an independent cybersecurity audit has been conducted. Published code can make parts of a system inspectable, but it does not prove that the system is fair or safe. If you cannot understand the code or its permissions, do not treat an explorer page or a verified-source label as a substitute for an informed technical review.

Read the audit report, not just the audit badge
An audit is a review with a defined scope, not a guarantee against loss. Check the report itself for:
- The auditor’s identity and the date of review.
- The contract addresses, code version, and components included in scope.
- Findings, their severity, and whether they were fixed or remain unresolved.
- Whether the deployed code or contract configuration changed after the review.
A report that covers only one component may not cover the sale contract, token contract, administrator controls, or the live deployment. Even a well-scoped audit cannot rule out fraud, misuse of administrator keys, economic flaws, or problems introduced by later changes.
Confirm people, progress, and outside claims
Look for evidence about the team and project outside the project’s own channels. Verify identities and experience through attributable sources. If the offer claims a partnership, endorsement, exchange listing, user base, or working product, seek confirmation from the named partner or another independent source.
Follower counts, testimonials, a polished website, and celebrity endorsements do not establish that an offering is genuine or that its claims are accurate. The SEC’s investor guidance cautions against relying solely on testimonials and describes impersonation and fake materials used in crypto-related scams. If an important claim cannot be confirmed independently, treat it as unverified rather than as a benefit.

Recognize pressure tactics and suspicious payment demands
Pause if the promotion promises high or guaranteed returns, claims there is little or no risk, pressures you to act immediately, or comes through an unsolicited offer. Instructions to send crypto to a wallet deserve particular scrutiny because transfers can be difficult or impossible to reverse.
A May 29, 2024 SEC Office of Investor Education and Advocacy alert, 5 Ways Fraudsters May Lure Victims Into Scams Involving Crypto Asset Securities, describes scammers using a supposed crypto “pre-sale” to promote a memecoin before selling, as well as fake interfaces and demands for extra fees or taxes to withdraw a displayed balance. Do not send more money to unlock funds or recover losses without independent verification. A demand for a new payment is not evidence that the displayed balance is real.

Never give an issuer, promoter, support agent, or recovery service your seed phrase or private key. The SEC Investor.gov bulletin Crypto Asset Custody Basics for Retail Investors, dated December 12, 2025, emphasizes that self-custody makes the owner responsible for the keys and warns against sharing them.
Before signing any wallet transaction, understand what it authorizes and who receives it. A signature or approval can grant permissions beyond the immediate purchase; if you cannot explain the transaction’s recipient and permissions, do not sign it.

Compare offerings using the same evidence
If you are evaluating more than one presale, apply the same questions to each. This is a way to organize diligence, not a scoring formula or endorsement.
| What to compare | Evidence to look for |
|---|---|
| Issuer and team | Named legal entity, accountable people, jurisdiction, and independently verifiable identities or experience. |
| Token and funds | Clear token rights, use of proceeds, allocations, insider vesting, and explanations of who controls funds. |
| Legal disclosures | Jurisdiction, registration or claimed exemption, and independently verifiable filing details where applicable. |
| Contracts and audit | Matching addresses and published code, disclosed administrator powers, audit scope, and unresolved findings. |
| Project claims | Independent evidence for product progress, partnerships, users, listings, or endorsements. |
| Sale and resale terms | Vesting, refund conditions, transfer restrictions, and realistic information about resale or liquidity. |
| Payment and promotion | Payment recipient and mechanics, plus any urgency, return promises, or unexpected withdrawal demands. |
Decide whether the possible loss is acceptable
A presale token may remain illiquid, never become tradable, or lose value if the project fails, changes terms, or loses access to funds. The SEC Investor.gov’s Exercise Caution with Crypto Asset Securities: Investor Alert identifies risks including volatility, illiquidity, technical failures, opaque control, and limited recovery. Consider whether you could absorb the loss of your entire contribution; do not borrow to participate or use money needed for essentials.
There is no project-specific pass or fail conclusion without the actual issuer, sale terms, jurisdiction, contract, and audit to review. If material answers are missing or cannot be checked, that uncertainty is itself relevant to the decision.
