Red‑Flag Checklist — Quick indicators of potential rug pullsUse this ordered checklist when you evaluate any new token. If you hit multiple red flags, treat the project as high risk.Anonymous or unverifiable team — No real names, LinkedIn, or verifiable track record. Anonymous teams aren't always scams but increase risk.Token contract ownership not transparent / renounced suspiciously — If ownership is renounced immediately without time to evaluate, or the contract has functions that allow minting/burning by the team, be cautious.Large team / developer token allocation — Check the tokenomics. Large percentages allocated to team, advisors, or private wallets are a major red flag.No or fake audit — No third‑party audit or an audit from an unknown/low‑quality firm. Even audited projects can be risky, but lack of audit increases uncertainty.Liquidity not locked or low liquidity — If liquidity pool (LP tokens are not locked or are in the team’s wallet, the team can pull liquidity and crash the price.Honeypot / transfer restrictions — Some contracts prevent selling (a honeypot. Use token scanners or try a small test sell to confirm transfers are allowed.Unrealistic marketing & fake metrics — Excessive promises, unrealistic returns, purchased followers, or copied/stock photos on the site and social channels.Rushed launch or constant pressure — Heavy FOMO tactics, time‑limited presales, or pressure to buy immediately are common in scams.Multiple token contract versions — Frequent token contract changes or switching contracts can be used to obfuscate prior issues.Poor or empty GitHub / whitepaper plagiarism — Low technical transparency and copied whitepapers are suspicious.Score the project: 0–2 minor concerns, 3–5 moderate concerns (consider avoiding, 6+ major red flags — do not invest.

Practical verification steps and mitigationAfter spotting red flags, use these concrete actions to verify or protect yourself:Check the contract on a block explorer — Look for ownership, minting functions, and token distribution. Search for large holder wallets and recent token mints.Verify liquidity — Confirm LP tokens are locked by a reputable locker (look up the locker address and lock expiry. Low or unlocked liquidity is a high‑risk sign.Test with a tiny amount — If you still want exposure, buy a very small amount first and attempt a sell to confirm no transfer restrictions.Review on‑chain history — Check token transfers for large dumps, whales, or repetitive patterns that indicate prior rug pulls.Use community and independent sources — Check multiple social channels, Telegram/Discord activity, and independent reviewers. Don’t rely on project‑controlled posts.Set limits in your wallet — Use small slippage settings, and don’t approve unlimited allowances; revoke approvals after trading.Prefer projects with verified audits and locked liquidity — Audits aren’t foolproof but are meaningful. Prefer auditors with established reputations.Keep records & report — If you identify a likely scam, record transaction IDs and report to exchange platforms, token trackers, and community forums to warn others.If you already lost funds: act quickly to gather on‑chain evidence, publicize details in reputable crypto communities, and file reports with authorities where applicable. Recovery chances are low, but rapid, transparent alerts increase the chance of freezing or tracing funds.Final takeaway: No checklist eliminates risk entirely, but disciplined, repeatable checks reduce the odds of falling for a rug pull. Prioritize transparency, locked liquidity, and independent verification before committing more than you can afford to lose.
