How to check a token for a scam before you buy
Most memecoin losses are not bad luck: the warning signs are usually visible in advance — the creator can mint more tokens, liquidity is thin, or half the supply sits in a few linked wallets. Here is what to check, and how to do it in a minute.
1. Contract: who controls it
The key question is whether someone can change the rules after you buy. Red flags: the power to mint more tokens, freeze wallets, set sell taxes, blacklist addresses or pause the contract. On Solana check the mint and freeze authorities and Token-2022 extensions such as permanent delegate and transfer hook.
Searching the code for function names is not proof. QUVR Pulse checks the bytecode and runs read-only probes; for Solana it reads the mint account itself.
2. Liquidity: can you actually sell
Look beyond the liquidity amount: compare it with market cap and check price impact — how far the price drops on a $1,000 sell. If liquidity is only a few percent of market cap, one large sell crashes the price and the market cap on screen is largely on paper.
3. Holders: who owns the supply
Measure the top-10 share excluding liquidity pools, bonding curves and burn addresses, or the number is misleading. Then check the creator’s share and wallets possibly linked to them: funded by the same address, receiving tokens straight from the creator, or buying in the same block.
Wallet links are a heuristic, not proof of common ownership. Exchanges and bots fund thousands of unrelated addresses, so such sources are filtered out.
4. Creator: what they are doing now
Creator sells in the first hours and days are one of the most reliable warning signs. Check the creator wallet’s history: buys, sells and transfers of this token.
5. Social hype ≠ safety
High social momentum means attention, not reliability. It is more useful to see who is posting about the token and whether those authors sell after their posts.

FAQ
Can a scam be detected with certainty?
No. A check finds known risk signs but cannot guarantee anything. That is why we say “low detected risk”, never “safe”. If a data source does not answer we show “No data”, not zero.
Does the service tell me which token to buy?
No. QUVR Pulse shows verifiable risks and facts, but gives no buy/sell advice and no price forecasts. “Low detected risk” does not mean the token will go up or that you cannot lose money.
Is it free? Do I need to connect a wallet?
Free, no sign-up. No wallet connection: the service only reads public blockchain data and never asks for a seed phrase or private key. Anyone asking for them in QUVR Pulse’s name is a scammer.
