How to Check a Solana Token Before Buying
Updated 2026-10-07 · 5 min read
No scanner can prove that a token is safe. A useful check verifies what can be verified on-chain and highlights risks that deserve attention before you sign a trade.
Start with the exact mint address
Names, tickers, logos and social profiles can be copied. The mint address is the unique identifier you should verify before trading.
Check authorities
- Is Mint Authority still active? If yes, supply may still be increased.
- Is Freeze Authority still active? If yes, supported token accounts may still be freezeable.
- Can metadata still be updated? Consider whether that matches the project's claims.
Check supply and holders
- Review total supply and whether it matches public claims.
- Look for unusually concentrated holder balances.
- Understand whether locked or vesting supply can become available later.
Check the real market state
- Current liquidity or bonding-curve stage.
- Whether the token has actually graduated when a project claims it has.
- Whether volume and price data come from a real active market.
- Whether liquidity is withdrawable, locked or controlled by a position owner.
For Fair Launch NEXT tokens
- Classic SPL with 1,000,000,000 supply and 6 decimals.
- Mint address ending in LMEME.
- Mint Authority revoked.
- Freeze Authority revoked.
- 85% (850,000,000 tokens) locked for 10 years.
- Meteora DBC before graduation and DAMM v2 after graduation.
- 100% of migrated LP configured as permanently locked after graduation.
What a clean scan cannot tell you
Revoked authorities, locked supply and locked liquidity can reduce specific technical risks, but they cannot guarantee demand, price stability, honest promotion, fair holder behavior or future returns.
Frequently asked questions
Can a rug checker guarantee safety?
No. It can surface verifiable signals and permissions, not predict future behavior or price.
What should I check first?
Verify the exact mint address first, then review authorities, holder concentration and the real market/liquidity state.
Does LMEME alone prove a token is safe?
No. LMEME identifies the required mint suffix for LaunchMemes NEXT, but it is not a promise of price performance or safety by itself.
Does permanently locked LP eliminate all risk?
No. It addresses a specific liquidity-withdrawal risk, not every market or holder risk.
