How to check a Solana token before you buy

1. Mint authority

The mint authority is the one account that can create new units of a token. While it exists, the supply can grow at any time, which dilutes everyone who already holds the token.

What to look for: the authority should be revoked (set to nothing). In QZMO the Mint tile reads “Not possible” when it is revoked and “Possible” when someone can still mint.

2. Freeze authority

The freeze authority can freeze individual token accounts. A frozen account cannot send or sell its tokens. Like the mint authority, it should be revoked. The Freeze tile shows “Not possible” when nobody holds that power.

3. Who controls the liquidity

A token is only tradable because a pool holds it next to a quote asset such as SOL or USDC. Whoever owns the pool's LP position can withdraw that liquidity. When that happens the price collapses and sellers have nobody to sell to. That is what a rug pull is: liquidity pulled out from under holders.

There are three states worth telling apart:

• Locked – the LP position sits in a locker contract until a set date.
• Burned – the LP tokens were sent to an address nobody controls, so the liquidity cannot be withdrawn.
• Neither – the owner can remove it whenever they like.

QZMO weights the locked share across all of a token's markets by their liquidity and shows it as a percentage. Pools with concentrated liquidity (Orca Whirlpool, Meteora DLMM, Raydium CLMM) work differently and have no comparable lock percentage, so the markets table shows “—” for them instead of a misleading 0 %.

4. What the creator still holds

The creator wallet can start with a large share. If it still holds a lot, a single wallet can move the price on its own. If the creator has already sold out, QZMO shows “Exited”. Neither is a verdict by itself; it is context for the next check.

5. Top-10 concentration

This is the share of the supply held by the ten largest wallets. On Solana, QZMO excludes liquidity pools and lockers, which hold tokens for trading rather than as investors, before it adds them up. A high number means a few wallets can move the price. There is no universal threshold, so compare a token with others of similar age and size. The holder distribution guide explains how to read it.

6. Connected wallets

Sometimes many wallets that look independent are not. Two patterns are common at launch: bundling (several wallets buy in the same block, often controlled by one party) and sniping (wallets that buy in the first moments after liquidity is added). QZMO uses RugCheck's wallet-network analysis to mark wallets that appear linked in amber on the holder map, and shows how many there are relative to the number of holders.

This is an indication taken from on-chain data. It is not proof that the wallets share an owner.

What these checks cannot tell you

Use the checks as a checklist of questions you can answer from the chain itself, then decide on your own.
