Practical overview
When it fits
Use it when preparing a Pump.fun token launch and you want the creation and buy transactions handled through the documented bundler workflow.
Who it is for
- Token creators preparing a Pump.fun launch with bundled buy transactions.
- Developers comfortable configuring a TypeScript command-line project and handling a keypair secret.
Documented uses
- Prepare token image and metadata files.
- Configure an RPC endpoint and main keypair secret for the bot.
- Bundle token creation with buy transactions on Pump.fun.
Requirements & limits
The project is a public GitHub repository under an MIT license. The documented workflow uses a local command line.
- The README describes bundling up to 20 buys.
- Setup requires an RPC endpoint and a main keypair secret in an environment file.
- Token preparation involves editing metadata.ts and the image and metadata files under /upload.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Prepare the bot and token metadata
Set up the repository and prepare the listed metadata files before creating a token.
Before you start
- An RPC endpoint
- The main keypair secret
- Node.js and npm
Steps
Clone the repository and change into its directory.
Install dependencies with npm install.
Rename .env.example to .env and set the RPC endpoint and main keypair secret.
Update metadata.ts, /upload/img.png and /upload/metadata.json.
Expected outcome
The repository and token metadata are prepared for the bot's documented token-creation workflow.
Guide limitations
- The README does not describe metadata fields or explain transaction settings.
- The documented preparation steps alone do not establish that a launch will succeed.
