What it is
Same-block buying means several wallets buy a token in the same block, often sent together so they land at once. Jumpbit Bundle Buy buys a token from several wallets in the same block. The mechanics are explained in how launch bundles work.
Why it matters to holders
Our measurements show how common same-block buying is: in September 2026, 30.5% of pump.fun launches had another wallet buy in the launch block and 11.2% had at least 10% of supply bought there, see the data. Holders check this because early wallets can hold a large share.
What Jumpbit Bundle Buy states
Jumpbit's page lists a base fee of about 0.002 SOL plus about 0.01 SOL per buy address, and does not say whether the base fee applies once per bundle. Its form supports up to 16 wallet addresses for purchases, while its FAQ says most developers use 10 to 15 and that you can add more. It sends buys in one Jito block through Jito's private bundle system, with auto-retry and adaptive tipping, fixed SOL or fixed token amounts per wallet, and wallet import. It says all actions run locally and keys never leave your machine.
Using it responsibly
- Disclose how much of the supply the launch team holds.
- Do not present team wallets as independent buyers.
- Follow the rules of the platform and your jurisdiction.
