What Gets Flagged

  • Multi-wallet concentration — several wallets collectively trade >X% of volume in one block

  • Single-wallet concentration — one wallet trades >Y% of volume in one block

Why It Matters

Pump groups coordinate buys in the same block to:

  • Spike the price quickly

  • Trigger momentum algorithms

  • Create FOMO before dumping

If we see 80% of a token's volume in one Ethereum block spread across 5 wallets, that's not organic — it's coordinated.
