Velocity Spike
A velocity spike is a sudden, sharp increase in the rate or volume of a wallet's transaction activity compared to its established baseline — many transfers in a short window after a period of relative quiet. It is a classic early-warning signal in both crypto and traditional transaction monitoring.

What it means
Baseline behavior matters more than absolute numbers here: a wallet that normally transacts once a week and suddenly makes forty transfers in an hour shows a meaningful spike even if none of the individual transfers is unusually large, while the same forty transfers from an active market-maker wallet might be entirely routine.
Velocity spikes commonly precede or accompany other patterns rather than standing alone — they often show up alongside a peel chain being executed quickly, a fan-out distributing stolen funds before they can be frozen, or a wallet racing to move funds out ahead of an anticipated freeze or law-enforcement action.
Real-world example
Wallets receiving funds from a fresh DeFi exploit typically show an extreme velocity spike within minutes, as the attacker rushes to fragment and move the stolen funds through multiple hops before the protocol team or exchanges can react.
