Pump.fun Rug Pull Red Flags
Mint Authority Not Revoked
The pump.fun token creator can mint unlimited new tokens at any time, diluting the supply and crashing the price. If mint authority is not revoked, this is a critical red flag and a classic pump.fun rug pull vector — the dev mints and dumps on the bonding curve or the post-graduation pool.
Active Freeze Authority
The pump.fun token creator can freeze any holder's token account, preventing them from selling or transferring. This is functionally a honeypot — your funds are trapped the moment the dev decides to pull the rug, even mid-bonding-curve.
Dev Wallet Pre-Load
Deployer wallets often buy a large slice of the supply at the bottom of the bonding curve, spread across multiple addresses to avoid detection. These tokens are held to dump on retail once the price rises. Guava traces deployer-linked wallets and flags suspicious pre-loaded holdings.
Bonding Curve Manipulation
Pump.fun prices tokens along a bonding curve that rises with buys. Devs manipulate this by pre-loading at the bottom, hyping the token to drive the curve up, then dumping their allocation — crashing the curve and leaving late buyers with heavy losses. Guava detects this pattern automatically.
Graduation Dump
When a pump.fun token reaches the end of its bonding curve it graduates and migrates to a Raydium liquidity pool. A graduation dump is when the dev immediately sells a large pre-loaded allocation into the fresh liquidity, crashing the price before retail can react. Guava flags tokens where dev wallets hold a large percentage of supply near graduation.
Fake LP Burn
Some pump.fun devs claim to have burned Raydium liquidity pool tokens to prove safety after graduation, but the burn is faked or only partial. Guava verifies the LP burn on-chain, confirming that liquidity tokens are truly burned or locked and not held by a deployer-controlled wallet ready to be pulled.

Frequently Asked Questions
How does the pump.fun rug checker work?
Guava uses RugCheck, the leading Solana token security engine, to analyse any pump.fun token address. We check for mint authority, freeze authority, bonding curve status, dev wallet pre-load, graduation risks, and liquidity manipulation — surfacing a clear risk score in under 2 seconds so you can decide whether a pump.fun token is safe to buy.
Is the pump.fun rug checker free?
Yes. Pump.fun rug pull detection is completely free on Guava. You can run a check on this page without signing up. Free accounts get 10 analyses per day. No credit card required.
What is a pump.fun rug pull?
A pump.fun rug pull is when the developer of a pump.fun-launched token abandons the project and extracts value from holders. This can happen through unrenounced mint authority (minting and dumping unlimited tokens), freeze authority (trapping holder funds), a graduation dump (selling the dev allocation the moment the token migrates to Raydium), or bonding curve manipulation that leaves retail holding worthless tokens.
What is the pump.fun bonding curve and how can it be manipulated?
Pump.fun uses a bonding curve to price tokens before they graduate to a Raydium liquidity pool. The price rises as more tokens are bought along the curve. Manipulation happens when devs pre-load wallets at the bottom of the curve, hype the token to drive the price up, then dump their allocation — crashing the curve and leaving late buyers with heavy losses. Guava detects pre-loaded dev wallets and flags this pattern.
What is a pump.fun graduation dump?
When a pump.fun token reaches the end of its bonding curve, it 'graduates' and migrates to a Raydium liquidity pool. A graduation dump is when the developer immediately sells a large pre-loaded allocation into the new liquidity pool the moment graduation completes, crashing the price before retail can react. Guava flags tokens where dev wallets hold a large percentage of supply near graduation.
What is a dev wallet pre-load on pump.fun?
A dev pre-load is when the token creator buys a large slice of the supply at the very bottom of the bonding curve, often across multiple wallets to avoid detection. These tokens are held to dump on retail once the price rises. Guava traces deployer-linked wallets and flags suspicious pre-loaded holdings before you buy.
Why is mint authority critical for pump.fun tokens?
Mint authority allows the token creator to mint unlimited new tokens at any time. If mint authority is not revoked on a pump.fun token, the dev can dilute the supply and dump on holders at will. This is one of the most common pump.fun rug pull vectors and a critical red flag that Guava checks automatically.
What is freeze authority on a pump.fun token?
Freeze authority lets the token creator freeze any holder's token account, preventing them from selling or transferring. This is functionally identical to a honeypot — the creator can trap your funds at will. A pump.fun token with active freeze authority should be treated with extreme caution.
Can a pump.fun token be rugged after graduation?
Yes. Even after a pump.fun token graduates to Raydium, it can still be rugged if the dev retains mint authority, pulls the new liquidity pool, or dumps a pre-loaded allocation into the fresh liquidity. Guava checks liquidity depth, lock status, and dev holdings at every stage of a pump.fun launch — pre-graduation and post-migration.
What is a fake LP burn on pump.fun tokens?
Some pump.fun devs claim to have burned liquidity pool tokens to prove safety, but the burn is faked or only partial. Guava verifies the LP burn on-chain, confirming that liquidity tokens are truly burned or locked and not held by a deployer-controlled wallet ready to be pulled.
How do I check a pump.fun token before buying?
Paste the pump.fun token mint address into the checker above. Guava inspects the bonding curve, mint and freeze authority, dev wallet holdings, holder concentration, and (if graduated) the Raydium liquidity pool to determine whether the token is safe. Unlocked liquidity, unrenounced mint authority, and dev pre-loads are flagged as major red flags.
What chains does Guava support for rug pull detection?
