In 2025, crypto fraud cost investors an estimated $9.3 billion globally — with presale and token launch scams representing the fastest-growing category. The good news: the vast majority of this fraud is preventable using basic security practices that most victims simply hadn't implemented. These 15 steps protect against the most common attack vectors.
The 15 Fraud Protection Steps
1. Use a Hardware Wallet for Significant Holdings
For any presale holdings above $2,000, a hardware wallet (Ledger, Trezor) provides offline private key storage that cannot be compromised by software malware, phishing sites, or browser extensions. Hardware wallets require physical confirmation of transactions — even if your computer is infected with malware, transactions cannot be signed without touching the device.
2. Never Share Your Seed Phrase
Your 12 or 24-word seed phrase is the master key to your wallet. No legitimate website, support agent, "airdrop claim," or "wallet recovery" process will ever ask for your seed phrase. Anyone who asks for it is attempting theft. Store your seed phrase offline only — never in email, cloud storage, or photos on your phone.
3. Verify URLs Before Every Interaction
Crypto phishing sites look identical to legitimate presale websites but use subtly different domains: uniswap.com (fake) vs. app.uniswap.org (real), or metamaask.io vs. metamask.io. Always navigate directly from the project's verified Twitter/X bio link — never from links in Telegram messages, Discord DMs, or Google search ads.
4. Never Click Links from DMs
Every unsolicited DM on Telegram, Discord, or Twitter offering "exclusive presale access," "early whitelist," or "support assistance" is a scam. Legitimate presales never approach investors via direct message with investment opportunities. Block immediately.
5. Verify Smart Contracts Before Connecting Your Wallet
Before connecting MetaMask to any presale website, verify the contract address the site is interacting with matches the address published in the project's official announcements. Compare on the block explorer. A malicious presale site might connect to a legitimate-looking interface while actually calling a drain contract.
6. Use Revoke.cash Regularly
Every time you connect your wallet to a DeFi protocol or approve a token spend, you grant permissions that persist indefinitely. Go to Revoke.cash (revoke.cash) and revoke any token approvals you no longer need — especially unlimited approvals. Unrequested approval exploits are one of the most common wallet drains.
7. Keep a Dedicated Wallet for Presale Participation
Use a separate wallet specifically for presale interactions — never connect this wallet to other DeFi activities or use it for long-term holdings. If it's compromised, you lose only the capital deployed for presales, not your entire portfolio.
8. Enable MetaMask Security Features
Turn on MetaMask's transaction simulation features (available in Settings → Security): these show you exactly what a transaction will do before you sign. A legitimate presale contract deposits tokens to your wallet; a drain contract removes all tokens. Transaction simulation reveals drain attempts before they execute.
9. Always Check Google — But Not the Ads
When searching for any presale or protocol, Google Ads (the top results marked "Sponsored") are frequently purchased by phishing sites. Scroll past all sponsored results to organic results. Even then, verify the URL matches the project's official domain before clicking.
10. Verify Team Identity Through Multiple Sources
A named team member claimed on a presale website should be verified across: LinkedIn profile (work history predates the project), Twitter/X (genuine engagement with industry content), and direct interaction in public AMAs. Impersonators create fake profiles — cross-reference multiple data points. See our presale phishing guide for fake team detection methods.
11. Check Contracts on Token Sniffer Before Investing
Token Sniffer (tokensniffer.com) automatically scans token contracts for common exploit mechanisms: hidden mint functions, honeypot code (can buy but not sell), high tax rates, blacklist functions, and proxy upgrade capabilities. Run any new presale contract through Token Sniffer before investing any amount.
12. Never Invest More Than 1-2% Per Presale
Position sizing is fraud protection. Even with all checks passed, presales fail — some through fraud, others through honest failure. A maximum 1-2% position size ensures any single failure is a learning experience rather than a financial catastrophe. See our rug pull guide for how the most sophisticated attacks work.
13. Verify LP Lock Independently
The single most important check against rug pulls: verify the liquidity pool lock on Team.Finance directly, not via a link provided by the project. LP locks prevent teams from removing the trading liquidity pool at any time. Any project without a verifiable LP lock should be treated as a potential rug.
14. Use Etherscan / Solscan Token Approval Tracking
Check your wallet's token approval history on Etherscan (etherscan.io/tokenapprovalchecker) or Solscan. Any unlimited approval to an unrecognised or old contract is a liability. Revoke immediately — the gas cost of revoking is far less than losing the approved tokens.
15. Trust Your Instincts on Pressure Tactics
Urgency, countdown timers, "only X spots left," "this offer expires in 3 hours," and influencer endorsements that feel coordinated are manipulation tools. Legitimate presales do not require you to make fast decisions — they provide adequate time for due diligence. Any investment opportunity requiring immediate action without research time is almost certainly a scam. See our unregulated crypto risks guide for manipulation tactic profiles.
