How DEX Screener Stopped Pump and Dumps with Blockaid
Introduction
DEX Screener is a real-time data platform for cryptocurrency traders. It tracks token prices, trading volume, and onchain trades across major networks including Ethereum, BSC, Polygon, Avalanche, and others.
Traders rely on DEX Screener to spot new opportunities and make informed investment decisions.

The challenge
In crypto trading, being early to a new token can mean the difference between significant profits and missed opportunities.
DEX Screener needed to list new tokens quickly to serve their traders. But they also needed to protect users from scams, particularly large scale pump and dump operations.

These scams created three major risks:
- Legal exposure (similar to lawsuits other platforms like Uniswap faced)
- Damage to DEX Screener's reputation
- User churn and lost revenue
To address this, DEX Screener implemented a combination of user reports and manual review by employees to identify and flag malicious tokens.
This process was accurate but increasingly slow and labor intensive.
The solution
DEX Screener had tried every onchain security solution on the market except Blockaid.
Nothing worked well enough, so they continued to rely on human moderators.
“I'll be honest: unless you have human moderators I have a hard time believing any tool is able to give us fast and accurate results for what is and isn't malicious (we tried several). I'd be extremely happy to be proven wrong though and happy to chat.“ - Andy, DEX Screener
Then they tested Blockaid. The proof of concept addressed their two key requirements:
- Speed: Mean time-to-detection (MTTD) in under 10 minutes of a new token being identified
- Accuracy: Maintaining a near-zero false positive rate to mitigate the serious consequences of malicious tokens
With their concerns addressed, DEX Screener implemented Blockaid's solution across two major chains: Solana and Base.
The end solution is simple: when Blockaid identifies a malicious token, DEX Screener flags it and ensures the token gets little to no exposure.
Results
Since implementing Blockaid, DEX Screener has freed up 160 hours per month that they used to spend checking tokens manually while achieving a near zero false positive rate.
The new system has also caught complex scams that would have been difficult to uncover in manual review.
In one example, Blockaid spotted a sophisticated rug pull on Base by finding connections between suspicious accounts and previously successful scams.
"Keeping up with the flood of pump and dumps and other scam tokens was a massive headache. Blockaid solved this for us." - Andy, DEX Screener
Recap
With Blockaid, DEX Screener solved what seemed like an impossible problem.
Instead of needing more people to check for scams manually, they now have an automated solution that detects scams faster and more accurately.
