What is robinhood-token-launcher?

Robinhood Token Launch is a TypeScript toolkit for creating, deploying, and managing ERC-20 tokens on Robinhood Chain, Robinhood's permissionless, Ethereum-compatible Layer 2 network built on Arbitrum Orbit, with mainnet launched July 1, 2026. There is no native chain token, gas fees are paid in ETH, and standard ERC-20 contracts deploy the same way they would on Ethereum, Base, or Arbitrum. The project includes an ERC-20 smart contract with a configurable name, symbol, decimal count, and initial supply, where the deployer can mint additional tokens after launch. Hardhat scripts handle compiling, deploying, minting, and verifying the contract on the Blockscout block explorer, and a separate TypeScript command-line tool built on the ethers library can deploy and inspect tokens without running the full Hardhat setup. Both the mainnet and a testnet are preconfigured. Getting started means installing dependencies with npm, copying an example environment file, and setting a deployer wallet's private key along with the target network and default token details. From there, the contract is compiled and deployed, with testnet deployment recommended before mainnet. After deploying, the token can be verified on Blockscout, and only the contract owner is able to mint more supply afterward. A local Redis instance, optional but enabled by default, is used to remember deployed tokens so they can be listed later with a dedicated command. If Redis is not running, deployment still works, the tool just skips saving that record and falls back to reading token details directly from the chain. The README also lists the manual network settings needed to add Robinhood Chain to a wallet like MetaMask. The README repeatedly warns that a real private key should never be committed to version control, that a throwaway wallet should be used for testnet work, and that deployments are permanent, so token details should be checked carefully first. This toolkit is aimed at developers who want a repeatable, scriptable way to launch and track ERC-20 tokens on Robinhood Chain.
