Building a Pons Bundler on Robinhood Chain with TypeScript
Building a Pons bundler on Robinhood Chain is less about sending multiple transactions and more about coordinating an entire launch workflow reliably. A useful open-source implementation is wooyang/pons-bundler , a TypeScript CLI for Pons v2 on Robinhood Chain. The project calls launchAndBuy , registers buyer wallets for the launch flow, and submits additional curve buys in parallel. It also includes wallet generation, funding, dry-run execution, buying, selling, and sweeping. This article walks through the architecture and the engineering decisions behind a production-oriented Pons launch-automation system. What Is a Pons Bundler? First, an important distinction. A Pons bundler is not an ERC-4337 bundler . The referenced implementation describes Robinhood Chain as FCFS and notes that there is no atomic multi-signer transaction. The launch and initial buy happen in one transaction, while additional buyer wallets submit separate transactions targeting the same launch window. The execution model is therefore closer to: Pons Launch │ ▼ launchAndBuy() │ ┌─────────┴─────────┐ │ │ Master Wallet Token + Curve │ ┌─────────────┼─────────────┐ ▼ ▼ ▼ Wallet A Wallet B Wallet C │ │ │ └─────────────┼─────────────┘ ▼ Parallel Buy Txs The goal is to coordinate execution, not to create a fake notion of atomicity. Project Structure A clean Pons bundler can separate the application into several layers: CLI │ ├── status ├── wallets ├── launch ├── buy ├── sell └── sweep │ ▼ Execution Layer │ ├── launch orchestration ├── wallet coordination ├── quote calculation └── transaction handling │ ▼ Pons Protocol Layer │ ├── Factory ├── LaunchAndBuy ├── Curve └── Token │ ▼ Robinhood Chain The repository is organized as a TypeScript CLI with its main library entry point under src/index.ts . The separation matters because CLI code should not contain all of your blockchain logic. Connecting to Robinhood Chain The first requirement is an RPC connection. A basic configuration can look like: import {
