How the index is made

Every new pump.fun coin arrives through a public creation stream. The spider checks a random sample of them 30 seconds after launch and counts the coin's other transactions that landed in the same block as its creation.

Bundled: 3 or more. Sniped: 1 or 2. Clean: none. A Jito bundle from the dev's own wallets looks exactly like this on chain, and so do the fastest sniper bots, so the index measures launch-block buying, not who is behind it. For that, open a coin in the scanner: its Web X-ray follows who funded the wallets.

Coins the spider could not read in time are counted as unknown and left out of the percentages.
