Big DEX Swaps
proSwaps above $500K on the highest-volume pools on Ethereum and Base — whale-sized flow worth watching.
What it is
A single swap of $500K or more clears on one of the highest-volume DEX pools on Ethereum or Base — a whale-sized trade big enough to move more than a retail order book.
Why it matters
A trade that size is a deliberate act by someone with real capital. It settles on-chain in full view, with its direction and dollar size readable from the transaction, before any of it is aggregated into a price chart. Stablecoin-to-stablecoin pools are excluded: a swap between two dollar pegs is not a directional trade.
How to read the alert
The alert reports the pool, the network, the direction and the USD size. Direction and size read together are the content: one $500K sell and a run of them into the same pool inside a short window are different events, and the alert stream is what shows you which of the two you are looking at.
