Robinhood Chain (4663)

An Arbitrum Orbit rollup. Native asset is ETH; blocks land roughly every 100 ms; the sequencer is first-come-first-served and there is no public mempool, so pending transactions are not visible before inclusion.

typescript

// EIP-3085: prompt any injected wallet (MetaMask, Rabby, ...) to add chain 4663
await window.ethereum.request({
  method: 'wallet_addEthereumChain',
  params: [{
    chainId: '0x1237', // 4663
    chainName: 'Robinhood Chain',
    nativeCurrency: { name: 'Ether', symbol: 'ETH', decimals: 18 },
    rpcUrls: ['https://rpc.mainnet.chain.robinhood.com'],
    blockExplorerUrls: ['https://robinhoodchain.blockscout.com'],
  }],
})

The Splitshot app prompts this automatically when a connected wallet is on another network.
