How to Read a Token's On-Chain Health: A Step-by-Step Checklist
What this checklist is for
You already know the tools from using Solscan and using DexScreener, and the theory from how token authorities work. This page strings them into a repeatable routine. It reports what can be seen on chain. It cannot tell you whether a coin will rise or fall, and it is not financial advice. Memecoins can lose all their value even when every box below is ticked.
Step 1: confirm you have the right token
Copy the contract address (the mint) from a source you trust, such as the official project channel, not from a search result or a message. Fake tokens often copy a name and logo. Paste the address into Solscan and compare it character by character with the one the project publishes. For the QNT memecoin, remember it is independent of Quantinuum Ltd, see the name overlap guide and verifying a contract.
Step 2: check the authorities
Solana's token docs describe the mint authority as optional, and say that if no mint authority is present, the mint has a fixed supply and no further tokens can be minted. The freeze authority is the optional right to freeze token accounts. On the Solscan token page, look for these fields.
- Mint authority: if it shows an address, someone can still create new tokens, which can dilute holders. A removed authority is shown as empty or none.
- Freeze authority: if it shows an address, someone can freeze accounts so those tokens cannot move.
- Token program: if the token uses Token-2022, look at the extensions, see the Token-2022 guide. A permanent delegate or transfer fee changes the risk picture.
Pump.fun launches commonly come without these authorities, but verify each token yourself rather than assuming.
Step 3: look at the holders
Open the Holders tab. Note the share held by the top 10 wallets, and then identify which of the biggest addresses are not real people. A liquidity pool account or a burn address will often be the largest holder and should not be counted as a whale. After removing those, ask how much the rest could move the price if they sold. See reading holder distribution and whale risk. Warning signs include many wallets funded at the same moment, with similar balances, which can mean one person controls them.
Step 4: find who owns the liquidity
From DexScreener, open the pair, then follow the pair address to Solscan. Find the pool and its LP token mint, then check who holds the LP supply. A large share at a burn address or a known locker means the original provider cannot simply withdraw. If a single normal wallet holds all the LP tokens, that wallet can remove the liquidity. Background is in the PumpSwap guide. Also check the amount: a pool holding a small amount of SOL moves sharply on small trades.
Step 5: read the DexScreener page
- Pair and DEX: confirm you are viewing the pair that matches the mint you verified. Several pairs for one token can exist.
- Liquidity: note the figure, then compare it with the market cap. A large market cap on very little liquidity means selling is hard.
- Transactions: look at buys and sells. Very uniform trade sizes at regular intervals can point to bots or wash trading, see wash trading.
- Age: the pair creation date matters, because the first hours are the most manipulated.
DexScreener says its data comes directly from the blockchains it tracks, through a custom indexer. That means it shows what happened, but it does not judge intent, and its social and info tabs are only as honest as what a project submits.
Step 6: score and decide
- Right contract confirmed.
- Mint and freeze authority absent, or understood and accepted.
- No surprising Token-2022 extensions.
- Top real holders not dominant.
- Liquidity locked, burned or at least large enough to exit.
- Trading history looks organic.
If several items fail, the sensible response is to skip the token. If all pass, you have only removed some of the common traps. Prices can still fall, and you should size any position as money you can afford to lose entirely, see memecoin risk management and how to spot a rug pull.

Frequently asked questions
What should the mint authority show?
Per Solana's docs, a mint with no mint authority has a fixed supply. An empty authority field on Solscan means no more tokens can be created. If an address is shown, more can be minted.
Why is the top holder sometimes a pool?
Pool and burn addresses hold large balances by design. They should be separated from real wallets when you judge whale concentration.
Does a clean checklist mean a token is safe?
No. It removes some common traps, but price can still fall to zero and other risks remain.
Where do I find who owns the liquidity?
Open the pair on DexScreener, follow the pool to Solscan, find the LP token mint and view its holders.
