FAQ

Pump.fun Bundle Checker FAQ

What is a Pump.fun bundle?

A bundle is a group of transactions submitted together so they can execute in a tightly coordinated way. For token launches, analyzing the first block can help show how supply was distributed immediately after creation.

What does the Bundle Checker analyze?

The checker is designed to inspect public Solana transaction data around a token's launch, including early buyers, same-block activity and the share of supply associated with those wallets.

Does bundled activity mean a token is unsafe?

No. Bundle activity is one data point, not proof of malicious behavior. It should be considered alongside holder concentration, creator activity, liquidity and other public on-chain information.

Do I need to connect a wallet?

No. Public token analysis only requires a Solana token address. You do not need to connect a wallet to use the checker.
