Everything that happens on a DEX is public — but “public on-chain” and “actually watchable” are different things. This monitor turns the firehose of swap events into a readable board: what is being swapped, in which pools, in what size, right now.

What does the swap monitor track?

Swap events decoded from the chain as blocks arrive: token pair, direction, size, and the pool that executed it. Aggregation keeps it usable — instead of raw event spam you get flow: which pairs are active, where volume concentrates, and whether a large swap just moved a pool’s price.

Why watch raw swap flow instead of price charts?

Because the swap is the cause and the chart is the effect. Price aggregators show you candles after the fact; the on-chain feed shows the actual transactions creating them — including the big single swaps that smaller candles hide inside. Size and direction at event granularity is the closest thing to watching the market’s tape.

What counts as a “big” swap?

The board ranks activity by size relative to the pool it hit, not just absolute value — a swap that drains a meaningful share of a shallow pool matters more to that token’s price than a larger swap through deep liquidity. That is the framing that makes the feed useful rather than just impressive.

Who is this for?

Traders watching for whale flow into or out of a token, liquidity providers tracking pool stress, and anyone who wants to see what on-chain markets look like when you remove the aggregator between you and the data.
