By the time a normal wallet gets in, the price has already moved.</p> <p>We built <a href="https://solbundle.app" rel="noopener noreferrer">SolBundle</a> to fix that — atomic Jito bundles that create the token <em>and</em> buy from up to 4 wallets in the same block, so nobody can front-run your own launch.</p> <p><strong>How it works</strong><br> <a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fa5actrobsrgnhgabu4q0.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fa5actrobsrgnhgabu4q0.png" alt=" " width="800" height="390"></a><a href=""></a></p> <ol> <li> <strong>Fund your wallets</strong> — generate or import wallets, top them up with SOL.</li> <li> <strong>Build the bundle</strong> — set your buy size or target %, SolBundle simulates and packs it.</li> <li> <strong>Send it</strong> — one click, the whole bundle lands in a single block via Jito.</li> </ol> <p>Wallet management is custodial: keys are encrypted server-side, and each wallet gets auto-numbered so you're not juggling addresses manually.</p> <h2> Free on-chain tools </h2> <p>Because building this meant writing a lot of Solana/Pump.fun analysis code anyway, we opened up a <code>/tools</code> section with free scanners:</p> <ul> <li> <strong>Bundle Checker</strong> — same-block buyer activity and bundled supply for any token</li> <li> <strong>First Buyers Scanner</strong> — who bought first, and whether they still hold</li> <li> <strong>Dev Wallet Checker</strong> — creator wallet's initial position vs. current status</li> <li> <strong>Holder Checker</strong> — real holder count and concentration, scanned directly on-chain</li> <li> <strong>Bonding Curve Calculator</strong> — live graduation progress, exact SOL remaining</li> <li> <strong>Token Scanner</strong> — all of the above in one pass</li> </ul> <p>Everything reads live from the chain rather than a cached snapshot — no wallet connection needed, no account.</p> <h2> Try it </h2> <ul> <li>App: <a href="https://solbundle.app" rel="noopener noreferrer">solbundle.app</a> </li> <li>Free tools: <a href="https://solbundle.app/tools" rel="noopener noreferrer">solbundle.app/tools</a> </li> </ul> <p>Would love feedback from anyone who's built around Pump.fun's bonding curve or Jito bundles — happy to compare notes in the comments.</p> solana web3 opensource
