Was this launch rigged?

Paste a coin. We trace where its first buyers got their money and tell you, in plain English, if one party quietly bought through many wallets, even when they hid it behind exchanges, bridges or throwaway wallets. New to this? What is a bundle in crypto →

About the bundle checker

A bundled launch is when one party buys a big part of a new coin at launch through many wallets, so it looks like real demand. Later those wallets can sell into the people who bought after them. The bundle checker traces where each of a coin’s first buyers got its money and groups the ones that were funded together.

How does it decide a launch was bundled?
It looks for first buyers funded by the same wallet or by the coin’s creator (a direct link), and for buyers funded in one tight batch from the same exchange, bridge or throwaway wallets with matching amounts (a pattern). Bridged money is followed to the wallet that sent it on the other chain.
Is buying in the same second a bundle?
Not on its own. Trading bots buy in the first second of most pump.fun launches. We only count wallets that are linked by how they were funded.
What does “direct link” vs “pattern” mean?
A direct link is a shared wallet you can see on-chain. A pattern is matching timing and amounts through a shared exchange, bridge or throwaway wallets. Patterns are circumstantial: a reason to look closer, not proof.
Why does the first check take a while?
We trace every first buyer on-chain. The first check of a coin can take 1 to 3 minutes. After that the result is saved and loads instantly for everyone.
Does it work on Robinhood Chain coins?
Yes. Paste a Robinhood Chain token (0x…). Blocks there are a tenth of a second, so we read the first ~3 seconds of trading and the last top-up each early buyer got before launch: one transaction or one wallet paying many of the first buyers is a direct link, and so is the creation transaction handing tokens to other wallets. Solana checks also follow buyers funded from Robinhood Chain, Ethereum or Base through the Relay bridge.
