TypeScript toolkit to deploy ERC-20 tokens on Robinhood Chain — Robinhood's EVM-compatible Layer 2 (Arbitrum Orbit) that launched mainnet in July 2026.

Deploy a mintable, burnable OpenZeppelin ERC-20 to testnet or mainnet, verify on Blockscout, and read on-chain token metadata from Node.js.

Gas is paid in ETH. Start on testnet before mainnet.

• Solidity ERC-20 (RobinhoodToken) — OpenZeppelin v5, owner-gated mint, burnable
• Hardhat + TypeScript deploy scripts for Robinhood mainnet & testnet
• Blockscout verification helper
• viem read helpers — fetch name, symbol, supply, owner without a wallet
• Wallet add-chain params exported for MetaMask / Rabby integration

cd robinhood-sniper
npm install
cp .env.example .env
# Edit .env — set PRIVATE_KEY (testnet deployer with ETH)
npm run compile

# Via npm script (recommended)
npm run create-token:testnet -- "My Token" MTK 1000000

# Or with flags / env vars
TOKEN_NAME="My Token" TOKEN_SYMBOL=MTK TOKEN_SUPPLY=1000000 npm run create-token:testnet

npm run create-token:mainnet -- "My Token" MTK 1000000

Output includes the contract address, tx hash, and a ready-to-run verify command.

TOKEN_ADDRESS=0x... MINT_TO=0x... MINT_AMOUNT=5000 npm run mint -- --network robinhood-testnet

npx hardhat run scripts/verify-token.ts --network robinhood-testnet -- 0xTokenAddress "My Token" MTK 1000000 0xOwnerAddress

npm run info -- 0xTokenAddress testnet

Copy .env.example to .env:

Never commit real private keys.

MetaMask → Add network → use these values (testnet):

• Network name: Robinhood Chain Testnet
• RPC URL: https://rpc.testnet.chain.robinhood.com
• Chain ID: 46630
• Currency: ETH
• Explorer: https://explorer.testnet.chain.robinhood.com

Or import from code:

import { WALLET_ADD_CHAIN_PARAMS } from "./src/config/chain";

// window.ethereum.request({ method: "wallet_addEthereumChain", params: [WALLET_ADD_CHAIN_PARAMS.testnet] })

import { fetchTokenInfo, ROBINHOOD_TESTNET } from "./src";

const info = await fetchTokenInfo("0xYourToken...", ROBINHOOD_TESTNET.chainId);
console.log(info.name, info.totalSupply);

• Use a dedicated deployer key with only the ETH you need for gas.
• RobinhoodToken grants mint rights to the owner — transfer ownership carefully.
• Audit and test on testnet before mainnet launches.
• This repo is a developer template, not financial advice.

• Robinhood Chain docs — Deploy a contract
