A rug pull checker reads a meme coin's contract address and tells you, before you buy, whether the people behind it can take your money by design. A good one does not hand you a single grade. It runs a short list of checks, says what each one found, and says plainly which ones it could not read. This lesson walks through the seven checks that matter on Solana and Robinhood Chain, what a good and a bad answer look like, and where the PumpPill Scanner shows each one.

What a rug pull checker should check

A mechanical rug is built into the token or its pool before launch. The developer keeps a power, then uses it. Because the power has to exist before it can be used, you can look for it ahead of time. These are the seven places to look.

1. Mint and freeze authority

On Solana a token can keep two keys. Mint authority lets the holder create new supply and sell it into the pool. Freeze authority lets the holder lock your wallet so you cannot sell.

Good answer: both revoked. Nobody can create more or freeze your wallet.
Bad answer: either one still held.

On Robinhood Chain the same powers live in the contract code. The Scanner's "Can it trap me by design?" question reads whether the source code is published, whether the owner still has admin control, whether the owner can swap the contract's code, and whether the contract exposes admin powers while the owner keeps control.

2. Liquidity: burned, locked, or pullable

The pool is the market. Whoever can withdraw it can end the market.

Burned: the withdrawal rights were destroyed. Nobody can pull the pool.
Locked: a third party holds them until a date. Read the date. A lock that ends next week is a countdown.
Not locked: the pool can be pulled at any time.

The mint, freeze and liquidity lesson covers all three keys in more depth.

3. Can it be sold

A contract can accept buys and refuse sells, or tax the sell so heavily that nothing comes back. The reliable test is a simulated sell against the live contract. It either returns a sane amount or it fails. A failed test sell means a honeypot: you can buy and cannot sell. The sell tax belongs in the same check.

Do not use the chart for this one. A token nobody can sell has no sellers, so its chart climbs smoothly. The can it be sold lesson explains why.

4. The launch bundle

Did the first buyers buy as one group? A bundle is several wallets, often funded from one place, that buy in the first seconds as a single coordinated buyer. A good checker says how many launch wallets there were, how many bought together and how they were tied, and whether that group still holds or has sold.

5. Top holders

How much do the top ten wallets hold? The number only means something with pools left out, because a pool is not a person. A high share in a few wallets means a few sellers can move the price against you.

6. The creator's record

The wallet that launched this token has usually launched others. How many, and how many of those were rugs, is public. A creator with a rug record is a serious warning.

7. Who is posting the contract on X

Search X by the contract address, not the ticker. A ticker search fills up with unrelated coins and spam. The useful answer is how many real accounts posted the address, when the first post was, and how many of the posts came from bots or repeat posters.

How the PumpPill Scanner answers them

Open /scan, paste a Solana mint or a Robinhood Chain address, and press Get the read. The read leads with two answers, Am I early? and What's my risk?, each one bold word with a clause. The risk word is Low, Medium or High, or Unclear when key checks could not be read. Under it sit the reasons, each line marked pass, fail or unread. There is no number out of 100.

On a Solana token's full read, the checks above map like this:

The contract: mint authority, freeze authority, the liquidity (burned, locked with the percentage, or not locked), a test sell, and the sell tax where one is set.
Bundle: "Did insiders load the launch, and are they still in?" How many wallets bought at launch, how many bought as one group and how, and whether that group has sold or still holds.
Holders: the top ten wallets' share with pools left out, and the creator wallet's share.
The creator: how many tokens the creator wallet launched before and how many we counted as rugs.
Who's talking about it: which X accounts posted the contract, with bots and repeat posters filtered out.

On Robinhood Chain the full read adds questions such as "Can it trap me by design?" for the contract powers and "Can I get out?" for the pool and the sell.

Checking from Telegram

You do not have to leave the chat to run a check.

In a group: add @PumpPill_Group_Scan_Bot to the group. It answers any contract address pasted there, on either chain, and works in a direct message too. On Robinhood Chain its reply has a line each for the contract, the launch buyers, the holders and X, plus a pool line when the liquidity can be pulled. On Solana it leads with the read's verdict sentence, the creator's record and who posted the contract on X.
Before you buy: in the PumpPill Trade Bot, paste a contract and tap Scan. The same read sits one tap before the buy.

Both replies link to the full read on the site.

How to read the result

A fail on the contract (mint or freeze still held, a failed test sell, a pullable pool) is a mechanical trap. Treat it as a stop.
A fail on the bundle, holders or creator is a warning about who can sell into you. It raises the risk word. It does not mean the token cannot move.
Unread means the check did not return an answer. The page says it in bold: "Unread is not clean." An unread line is an open question you still have to close.
Read the time stamp. Authorities can change while they still exist. A read from this morning says nothing about this afternoon.

What it does not tell you

A clean check is not a promise. It rules out the ways a token can be built to take your money. It says nothing about whether anyone will want the token next week. Most money in meme coins is lost to projects that simply fade, and no contract check can see that coming.

Unread is not clean. A checker that cannot read a line and shows it as a pass is hiding a gap from you.

A rug pull checker reads the token, not your trade. It does not know your size, and it does not know how much of the pool your position would be. Look at the liquidity before you size anything.

The X section says who posted the contract. It does not say whether they were paid to.

What the video says the full transcript, for reading or searching

Someone sends you a contract address. How do you find out what is behind it before you buy? The PumpPill Scanner is one paste box and one read. Paste a Solana or Robinhood Chain contract and it says, in plain words, who is behind the coin, who holds it, and how far it has run. No account, and nothing asks for your wallet. Step one. Open pumppill dot org slash scan. The box takes a Solana mint, or a Robinhood Chain address, the kind that starts with zero x. If it is not a contract address, the page says so. Step two. Paste the address and press Get the read. No address handy? The chips under the box offer a few coins from the trending board. Step three. Read the two answers first. Am I early: how far the coin has run from launch, from its peak, and from where PumpPill first logged it. What's my risk: what the contract lets its owner do, how concentrated the holders are, and whether the pool is locked. Green for low, yellow for medium, red for high. Step four. Read the reasons. Each line is a check the read ran, with a pass, a fail, or an unread mark beside it. Unread means we could not check that item. The page says it in bold: unread is not clean. Treat an unread line as an open question, not a pass. Step five. Check the time stamp under the list. A stored read describes the coin as it was at that moment; if it is weeks old, read it that way. Step six. If the page says it has no stored read for this contract, follow the link to the full read, which starts a fresh scan. On Robinhood Chain that takes about fifteen to seventy-five seconds. The full read page leads with the same two answers, then asks four more questions. Can it trap me by design? Has the smart money already left? Is there anything actually here? Can I get out? Its first line is one sentence: the risk answer when there is one, otherwise the worst answer reached. Lower down, the bundle read asks who funded the early buyers, what they still hold, whether they sold, and whether the pool could pay them out; a bag it cannot is flagged. Beside the read, the page lists the six things every read answers: am I early, what's my risk, did insiders load the launch, who holds it now, is smart money in, who is talking about it. Pools are left out of the holder count, because pools are not people. Step seven. Scroll down to the board. It lists what both chains are trading right now; click a row and its read replaces the one above. In Our read, Unclear means the stored read has no one-word risk, N A means no read yet. Under the read, Buy opens our Telegram trade bot with the contract loaded. It is there whatever the risk word says; the risk is stated beside it. What it does not tell you. The Scanner reads the coin at a moment in time. It does not predict the price; a clear read is evidence, not a recommendation. It does not see your wallet, your position, or your entry, and it will not fill an unread line with a guess. Neither should you. Here is what to do. Open pumppill dot org slash scan, paste the next contract someone sends you, and read the two answers before anything else about the coin.
