Note.* Uniswap isn't deployed on Robinhood testnet, so a mock router stands in there. Graduation was still verified against the real mainnet Uniswap via a fork.

Add the testnet to your wallet

javascript

await window.ethereum.request({
  method: "wallet_addEthereumChain",
  params: [{
    chainId: "0xb626", // 46630
    chainName: "Robinhood Chain Testnet",
    nativeCurrency: { name: "Ether", symbol: "ETH", decimals: 18 },
    rpcUrls: ["https://rpc.testnet.chain.robinhood.com"],
    blockExplorerUrls: ["https://explorer.testnet.chain.robinhood.com"],
  }],
});

Heads up.Mainnet launchpad addresses aren't published yet — the contract is deployed after an audit. Until then, only use testnet ETH.
