What did your swaps give away?

Most of it never reaches a searcher's bid.

48Club and BlockRazor build most BNB Chain blocks. Their own arbitrage contracts trade inside the blocks they build, so they take these gaps first; no outside bid can outrank a builder inside its own block.

What did your swaps leak?

Your address is sent in the request body, not the URL, and nothing is stored about who looked. Each row links your swap and the transaction that took the gap behind it.

1. An arbitrage is a transaction whose sender ends with more of a token it both paid into a pool and took out of one, and less of none.
2. The swap it took from is the nearest earlier swap on one of its pools in the same block, at most three positions back.
3. What was taken is that arbitrage's profit, including what it paid on to the builder and validator. It is a floor on what the swap gave away.
4. Native BNB leaves no log, so every arbitrage that wraps, unwraps or uses a pool manager is read from a call trace. A row that claims more than half the swap's own value is dropped rather than shown.

Our node can trace only recent blocks, so this record starts on 23 September 2026 and grows from there. Sandwich attacks were measured too: over 20 hours of blocks we found essentially none against users. On BSC today the value goes to backruns, not sandwiches.
