No checklist can guarantee you will never get rugged — the most sophisticated rug pulls bypass most standard checks. But the majority of rug pulls involve detectable warning signs that a systematic pre-entry check will catch. This guide covers the most reliable signals.
Check contract authorities
The most important technical checks for Solana tokens:
- Mint authority: If the mint authority has not been revoked, the developer can print new tokens at will, diluting your holding to zero. Check this on Solscan or use a dedicated rug checker. For any token you hold meaningful value in, mint authority should be revoked.
- Freeze authority: If freeze authority is active, the developer can prevent your wallet from selling. This is a severe red flag.
- Update authority: Ability to update the token's metadata — less immediately dangerous but allows the developer to change token name/symbol, which is used in some social engineering scams.
Check wallet distribution
Use Bubblemaps or a similar tool to visualize the token's holder distribution:
- Single wallets or clusters holding 10%+ of supply are major red flags
- Many wallets funded from the same source suggest coordinated insider control
- Developer wallet still holding a large position significantly increases exit scam risk
- High bundle percentage at launch (visible on GMGN) means early insiders hold large supply at low cost basis
Check liquidity status
For tokens that have graduated from pump.fun to Raydium:
- Is liquidity locked? Check the lock period — short locks (24–72 hours) are essentially no lock
- Who owns the LP tokens? Developer-owned LP can be withdrawn at any time
- How deep is the liquidity? Shallow pools create extreme price impact on sells
Behavioral red flags
Beyond the contract checks, behavioral signals:
- Team completely anonymous with no verifiable history
- Social media accounts created within days of token launch
- Promises of "huge partnerships coming soon" without specifics
- Aggressive pressure not to sell, extreme shaming of anyone who questions the project
- Chart patterns showing large sells from dev wallet shortly after promotion
The limits of due diligence
A determined scammer can pass most of these checks. They can renounce mint authority, create aged social media accounts, use multiple obscured wallets, and construct convincing front-end displays. The best protection against sophisticated scams is position sizing: treat any meme coin entry as a lottery ticket and size accordingly. If you only risk what you can lose completely, no single rug can be catastrophic.
