TOOLFree bundle forensics — Ethereum mainnet

Was it
bundled?

Paste any ERC-20 contract. We scan first-block buyer clustering, supply concentration, router fingerprints, and honeypot signals — the same engine our console uses.

THE OTHER SIDE OF THE TRADE

Run your own
block-zero launch.

The same forensics power the launcher. Atomic and private — free tier available.

REFERENCEHow bundle detection works

What a bundle checker actually reads

Every launch leaves the same evidence on-chain: who bought in the first block, how much each wallet took, where their funds came from, and which router they went through. A bundle checker reads that evidence and tells you whether the opening buys look like one actor or a crowd. Nothing here is private data — it is all public, just tedious to assemble by hand.

First-block buyer clustering

How many distinct wallets bought in the very first block, and whether they behave like one actor. A launch where twenty wallets each bought an identical amount in block zero was coordinated, whatever the holder count suggests.

Supply concentration

What share of supply the top holders control. High concentration is not proof of anything by itself — plenty of honest launches start concentrated — but it bounds how much selling pressure one decision can create.

Router attribution

Which router the early buys went through. Buys routed identically through the same contract in the same block are a stronger coordination signal than the wallet count alone.

Honeypot signals

Whether the contract permits selling. Sells-disabled and tax-trap patterns are detectable before you commit funds, and they are the single most expensive thing to find out afterwards.

Reading the result

Treat the output as evidence, not a verdict. A high clustering score means the first buys were probably coordinated — that is a fact about execution, not about intent. Pair it with concentration: coordinated buys holding 5% of supply is a very different position from coordinated buys holding 40%. And a honeypot flag is the one signal that is categorical: if you cannot sell, nothing else on the page matters.

Common questions

What is a bundle checker?
A bundle checker inspects a token's launch on-chain to work out whether the first buys were coordinated — one person buying through many wallets in the same block — rather than organic demand from unrelated buyers. It reads public chain data, so it needs nothing from you but the contract address.
How do you check if a token was bundled?
Look at the first block of trading. Count the distinct buyer wallets, compare their buy sizes, check whether they were funded from a common source, and see which router they used. Coordinated launches show tight clustering on several of those at once. This tool does that automatically from the contract address.
Does a bundled launch mean a token is a scam?
No, and treating it that way will mislead you. Bundling is an execution technique: it controls how the creator's own buys land. Plenty of legitimate projects bundle, and plenty of unbundled tokens are worthless. What bundling tells you is how much supply the launcher likely holds and how early they got it — useful context for sizing risk, not a verdict.
Is this bundle checker free?
Yes. There is no sign-up, no wallet connection and no rate limit on ordinary use. Paste a contract address and read the result.
Is this a honeypot checker too?
Yes. One of the four signals it reads is whether the contract actually permits selling — sells-disabled logic and tax traps are detectable before you commit funds. That check is the one categorical result on the page: if you cannot sell, no other signal matters.
Which chains does it support?
Ethereum mainnet ERC-20 tokens. It does not currently read Solana or pump.fun launches, so a Solana mint address will not return a result.
