Chain reference

Robinhood Chain for developers

Everything you need to point a wallet, a script or an indexer at Robinhood Chain: the RPC, chain ID 4663, the explorer, gas token, WETH, the Uniswap V3 deployment and where the tokenized stocks come from. Values on this page are read from Vectr's live config.

Network

Add the chain

Network name: Robinhood Chain
Chain ID: 4663hex 0x1237
RPC URL: https://rpc.mainnet.chain.robinhood.com
Native gas token: ETH (Ethereum, 18 decimals)
Block explorer: robin.etherscan.io
Stack: Arbitrum Orbit (EVM)
WETH: 0x0bd7d308f8e1639fab988df18a8011f41eacad73
USDG: 0x5fc5360d0400a0fd4f2af552add042d716f1d168

Robinhood Chain is an Arbitrum Orbit chain, so anything that speaks EVM JSON-RPC works unchanged: viem, ethers, Foundry, Hardhat. Gas is paid in ETH. The public RPC is rate-limited; use a provider such as Alchemy for indexers and load tests.

Wallet

Add it programmatically

// viem
import { defineChain } from "viem";
export const robinhoodChain = defineChain({
  id: 4663,
  name: "Robinhood Chain",
  nativeCurrency: { name: "Ethereum", symbol: "ETH", decimals: 18 },
  rpcUrls: { default: { http: ["https://rpc.mainnet.chain.robinhood.com"] } },
  blockExplorers: { default: { name: "Etherscan", url: "https://robin.etherscan.io" } },
});

// wallet_addEthereumChain
await window.ethereum.request({ method: "wallet_addEthereumChain", params: [{
  chainId: "0x1237", chainName: "Robinhood Chain",
  nativeCurrency: { name: "Ethereum", symbol: "ETH", decimals: 18 },
  rpcUrls: ["https://rpc.mainnet.chain.robinhood.com"], blockExplorerUrls: ["https://robin.etherscan.io"],
}] });

DEX

Uniswap V3 on this chain

The canonical Uniswap V3 deployment. Vectr graduations mint a full-range position here.

Tokenized stocks

197 stock tokens as pairing assets

Robinhood issues US stocks and ETFs as plain ERC-20s on this chain. Vectr mirrors the registry and exposes it over its own API.

Registry (Robinhood): GET https://api.robinhood.com/rhj/assetsTicker, name, contract address per chain, currentMultiplier, status
Quote (Robinhood): GET https://api.robinhood.com/rhj/prices/{SYMBOL}USD bid and ask for the token, not multiplier-adjusted
Registry (Vectr mirror): GET https://api.vectr.bot/stocks?q=nvSame data plus the multiplier-adjusted USD price
One stock (Vectr): GET https://api.vectr.bot/stocks/NVDA
Pairing assets enabled on Vectr: GET https://api.vectr.bot/configquoteAssets[]: address, decimals, curve seed and graduation threshold per asset

Stock tokens carry a multiplier that folds splits and dividends into the token's value without rebasing balances. If you price them, read how stock-token multipliers work first; a share price alone is wrong for 28 of the 194 tokens in the registry right now.
