Practical overview

When it fits

Use it when a token launch and multi-wallet buys need to be coordinated in one Jito bundle, and check that its SDK and transaction logic support the relevant Pump.fun contract features.

Who it is for

  • Developers or operators building a Pump.fun token-launch workflow.
  • Users who need to coordinate bundled purchases across multiple wallets.

Documented uses

  • Launch a token through the Pump.fun API.
  • Coordinate buys from up to 20 wallets in the same block with a Jito bundle.
  • Configure a Solana lookup table address for transaction construction.
Before you choose

Requirements & limits

The repository is public and declares the MIT License.

  • The documented workflow supports up to 20 wallets.
  • The README identifies lookup table configuration as an important part of constructing the transaction.
  • The README warns that older bundlers may not work with newer Pump.fun contract features unless their SDK is updated.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Configure a lookup table for bundled transaction construction

Prepare a Solana lookup table address for constructing a Pump.fun launch and bundled-buy transaction.

Before you start

  • A Solana lookup table (LUT) address to configure.

Steps

  1. Configure the LUT address in the bundler.

  2. Use the configured address when making the transaction.

Expected outcome

The transaction is constructed using the configured lookup table address.

Guide limitations

  • The README does not provide configuration details or commands.
  • The README warns that the current Pump.fun contract includes newer features such as Pump AMM, and older bundlers may not work unless their SDK is updated.
