Most Solana rugs aren't clever. They leave clues on-chain, in plain sight, and the clues take about two minutes to read. This guide walks through the checks that matter, in the order that catches the most problems fastest.
One rule first: always work from the mint address, never the name or ticker. Anyone can launch a coin with any name. (More on that in our guide to spotting copycat coins.)
1. Can the dev print more tokens or freeze yours?
Two settings on every Solana token decide how much control the creator kept:
- Mint authority: if it's still active, someone can create new tokens at any time and dump them on holders.
- Freeze authority: if it's still active, someone can freeze your tokens so you can't move or sell them.
For a meme coin, you want both disabled. Coins launched on Pump.fun normally come with both turned off, so on those coins this check usually passes and the real risks are elsewhere (keep going).

2. Can you actually sell it?
A coin you can buy but not sell is the worst trap in the trenches. On Solana this usually happens through an active freeze authority, special token settings (Token-2022 extensions) or simply no working market to sell into.
The best test is a live sell quote: ask a swap router what you'd get for selling a small amount right now. No quote means no exit.

3. Who holds the supply?
Every Pump.fun coin has 1 billion tokens, so holdings read as clean percentages. Look at the top holders (ignoring the bonding curve or pool account itself):
- A few wallets holding a large share can crash the price by selling.
- Several "different" wallets holding similar amounts can be one person in disguise.
There's no magic cutoff, but the more concentrated the top of the list, the more one decision can sink everyone else.
4. Is the volume real?
Big volume looks like demand. Often it isn't. Bots trade with each other to push coins onto trending lists.
In one coin we scanned 10 minutes after launch, the chart showed about $172,000 of volume in the first hour. Only about 2% of the buy volume looked organic. The rest was bots.

5. Who launched it, and what happened to their last coins?
This is the check most people skip, and it's often the most telling. Look up the wallet that created the token.
That same coin's creator wallet had launched 2,847 tokens. 23 of them graduated off the bonding curve. That's under 1%. A dev with thousands of launches isn't building one project; they're running a numbers game.

6. Check liquidity against market cap
Liquidity is how much money is actually in the pool. If market cap is huge and liquidity is tiny, a single sell can move the price a lot, and you may not get out at anything close to the price on screen.
The fast way
You can do all of this by hand with a block explorer, a DEX chart and a swap app. Or you can paste the mint address into SENTINEL, which runs 12 checks at once, including a live sell quote, holder concentration, organic volume and the dev's launch history.
If a check can't run, SENTINEL says UNKNOWN instead of quietly passing it. The best verdict it gives is "No red flags in these checks," never "safe," because no scanner can see everything.

Not financial advice. On-chain checks reduce risk; they can't remove it. Data from third-party sources can lag or be wrong. Never trade money you can't afford to lose.
