1. Start with the pool's age
Nothing predicts a rug better than how new the main pool is. In our journal of 1,876 Solana memecoins, coins whose main pool was under an hour old rugged within a day 83% of the time; 1 to 6 hours, 64%; 6 to 24 hours, 35%; 1 to 3 days, 21%; a week to a month, 2%. A brand-new coin isn't automatically a rug, but the odds start against you, and every other check matters more.
2. Check the liquidity is real
A pool's "liquidity" figure usually counts both sides: the SOL (or USDC) and the token itself, priced at the token's own price. A fake pool can claim millions while holding a few dollars of SOL. Look at the quote side: for a SOL or stablecoin pool, the real liquidity is about twice what's on the SOL side. If that's under a fifth of the claimed total, there's almost no real money in it.
Then ask who can take it out. Liquidity can be locked, burned, or withdrawable by whoever provided it. Withdrawable liquidity isn't a rug by itself (plenty of healthy pools are), but withdrawable liquidity held by the dev or launch insiders is. Read more in is the liquidity locked?
3. Look at the launch
Was the launch bundled? A bundle is a set of wallets buying in the same block as the creation, usually run by the creator. If those wallets still hold a big share, they decide when the chart ends. Also check the snipers (first-second buyers outside the bundle) and the first 200 buyers: are they still holding, or did they sell into you?
4. Read the dev wallet
How much does the creator still hold? Have they sold, or moved tokens to fresh wallets with nothing coming back (a quiet way to sell later)? Most telling of all: what happened to their other coins. A creator with five or more launches and none graduated, or whose past runners all collapsed 90%, has shown you the plan. See how to check a dev wallet.
5. Check the holders, not the holder count
A holder count is easy to fake: one team splits supply over dozens of wallets. Look at the shape instead. Real buying makes a power law: the biggest holder holds many times what the 50th does. Farmed coins look flat (dozens of wallets within a few percent of each other) or full of brand-new wallets. On one farmed runner we checked, 42 of the top 50 holders were under three days old; organic coins had 1 to 7. More in top holders and bubble maps.
6. Read the contract
On Solana the two settings that can hurt you are the mint and freeze authority. A live freeze authority can freeze your token account so you can't sell. A live mint authority can print new supply. Token-2022 tokens can also carry extensions like a permanent delegate (someone else can move or burn your tokens) or transfer fees. pump.fun coins have both authorities revoked at launch; other launchpads and hand-made tokens may not.
7. Look at who's paying to promote it
Paying for a DEX profile, boosts and ads is normal. Paying for them while the chart falls, or a sudden wall of copy-paste posts from caller accounts, is a pattern that often comes before an exit. See what DEX paid means.
All of it in one report
Trenchie runs every check above on any Solana token and writes the result in plain English, red flags first, ending in one of four verdicts. The checks are weighted by how often each one actually preceded a rug in our own record, not by guesswork.
| Check | What we look at | Why it matters |
|---|---|---|
| Liquidity | Real money in the pools (not the token's own side priced at its own price), how much is locked or burned, and who can withdraw the rest | A pool that can be pulled is the classic rug. A pool that "holds $5M" of a token nobody can sell into holds nothing |
| Launch | Bundled buys in the launch block, snipers in the first second, the first 200 buyers and whether they still hold | Insiders who bought the supply at launch decide when the chart ends |
| Dev wallet | What the creator holds, sold or moved, their creator rewards, and every coin they launched before and how those ended | A dev with 30 launches and no graduations is telling you how this one ends |
| Holders | Top 10 share (pools, lockers and burn addresses taken out), linked wallet groups on a bubble map, brand-new wallets, same-size wallets | One team spread over 50 wallets looks like 50 holders until you check |
| Contract | Mint and freeze authority, risky Token-2022 extensions, editable metadata | A live freeze authority can stop you selling. A live mint authority can print supply |
| Promotion | When it paid DEX and at what market cap, boosts and ads bought in the last week, caller groups and copy-paste X waves | Heavy paid promotion on a falling chart is a known exit pattern |
| Market | Pool age, volume momentum, in-and-out bot volume, sells by dev and insiders right now, the trend on the daily and hourly charts | The same coin can be fine at 9am and dumping at 9:15 |
Questions people ask
Is there a free Solana rug checker?
Yes. Trenchie's risk report is free for any Solana token: paste the contract address at trenchie.trade. No sign-up needed.
Can a token with no red flags still rug?
Yes. No checker can see the future, and a clean report means nothing major was found, not that the coin is safe. In our record, coins with no big flags rugged within a day 6.5% of the time, against 56% for High risk.
What is the single most useful check?
The main pool's age. Coins whose pool was under an hour old rugged within a day 83% of the time in our record; coins over a week old, about 2%.
Do pump.fun coins have mint or freeze authority?
No. pump.fun revokes both at launch, so those two checks pass for every pump.fun coin. The risks on pump.fun are in the launch, the dev and the holders.
