We built a same-block launch bundler for Solana memecoins - here's how it works
Every Pump.fun launch has the same problem: the second your token goes live, snipers and bots see the transaction before your own buy lands. By the time a normal wallet gets in, the price has already moved.
We built SolBundle to fix that — atomic Jito bundles that create the token and buy from up to 4 wallets in the same block, so nobody can front-run your own launch.
- Fund your wallets — generate or import wallets, top them up with SOL.
- Build the bundle — set your buy size or target %, SolBundle simulates and packs it.
- Send it — one click, the whole bundle lands in a single block via Jito.
Wallet management is custodial: keys are encrypted server-side, and each wallet gets auto-numbered so you're not juggling addresses manually.
Free on-chain tools
Because building this meant writing a lot of Solana/Pump.fun analysis code anyway, we opened up a /tools section with free scanners:
- Bundle Checker — same-block buyer activity and bundled supply for any token
- First Buyers Scanner — who bought first, and whether they still hold
- Dev Wallet Checker — creator wallet's initial position vs. current status
- Holder Checker — real holder count and concentration, scanned directly on-chain
- Bonding Curve Calculator — live graduation progress, exact SOL remaining
- Token Scanner — all of the above in one pass
Everything reads live from the chain rather than a cached snapshot — no wallet connection needed, no account.
Try it
- App: solbundle.app
- Free tools: solbundle.app/tools
Would love feedback from anyone who's built around Pump.fun's bonding curve or Jito bundles — happy to compare notes in the comments.
