Building a Pons Bundler on Robinhood Chain with TypeScript

A Pons bundler is not an ERC-4337 bundler, but rather coordinates an entire launch workflow reliably. The open-source implementation is wooyang/pons-bundler, a TypeScript CLI for Pons v2 on Robinhood Chain. It handles launchAndBuy, registers buyer wallets, and submits additional curve buys in parallel. The architecture separates the application into layers: CLI, Execution Layer, and Pons Protocol Layer.

The CLI includes commands for status, wallets, launch, buy, sell, and sweep. The Execution Layer manages launch orchestration, wallet coordination, quote calculation, and transaction handling. The Pons Protocol Layer consists of Factory, LaunchAndBuy, Curve, and Token contracts. To connect to Robinhood Chain, a basic RPC configuration is required.

Distinct from a blockchain transaction failure, an RPC failure should be handled appropriately. Contract addresses are documented in the README instead of scattered throughout the codebase. A PonsConfig interface is used for contract addresses and RPC URL. Before spending gas, it's important to check if launch is available using the canLaunch state.

Wallet management includes commands for generating, funding, listing, and sweeping buyer wallets. Each wallet has explicit state: READY, FUNDED, USED, or FAILED. Private keys should be encrypted and stored separately from the application to prevent security breaches. The core Pons launch flow involves validating, quoting, building a transaction, signing, broadcasting, waiting for receipt, and reading the resulting state.
