Robinhood Chain RPC, chain ID and developer reference

The Robinhood Chain RPC URL is https://rpc.mainnet.chain.robinhood.com and the chain ID is 4663. Below: RPC providers with WebSocket, adding the chain to MetaMask, testnet, finality, the explorer, WETH, every Uniswap deployment and where the Stock Tokens come from. Chain values are read from Vectr's live config.

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 and not meant for production: indexers, bots and load tests belong on a provider (below).

Robinhood is the authority for these values: the network facts come from its connection guide and wallet setup page, contract verification is covered in its deploy guide, and the Stock Token registry is Robinhood's own. This page is a secondary reference kept by Vectr, not official Robinhood documentation; each row says where its value comes from.

Public RPC

Robinhood Chain public RPC endpoints, live

Every keyless endpoint that serves chain 4663, from Chainlist, ethereum-lists and Robinhood's guide. Vectr's backend probes each one every 30 seconds for its latest block, and every 10 minutes for the widest eth_getLogs range it accepts. Last check: 10 November at 16:35 UTC.

Latency is measured from Vectr's server, not from you. "Behind" means the endpoint's head is more than 15 seconds older than the freshest one. Privacy is Chainlist's label for what the operator says it logs. Every public endpoint is rate-limited: indexers and bots belong on a keyed provider. The same probe data is served as JSON at GET https://api.vectr.bot/config/rpcs.

Stock Tokens

194 Stock Tokens as pairing assets

Robinhood Assets (Jersey) Limited issues them as tokenised debt securities that track US shares and ETFs; on-chain each is a plain ERC-20. Vectr mirrors Robinhood's registry and serves 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}Raw bid and ask of the underlying share, not multiplier-adjusted; cached 15s
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

Every Stock Token enabled on Vectr, with its contract address, is on the Stock Token addresses page. 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 54 of the 204 tokens in the registry right now.

FAQ

Robinhood Chain questions

What is the Robinhood Chain RPC URL?

The public RPC endpoint is https://rpc.mainnet.chain.robinhood.com. It speaks standard EVM JSON-RPC, so viem, ethers, Foundry and Hardhat work unchanged. Robinhood rate-limits it and does not recommend it for production; its connecting guide names Alchemy as the recommended provider, and QuickNode, Chainstack and dRPC also serve chain 4663.

Is there a free Robinhood Chain RPC without an API key?

Yes. Besides Robinhood's own https://rpc.mainnet.chain.robinhood.com, 10 keyless public endpoints answered for chain 4663 at Vectr's last check (10 November at 16:35 UTC): https://robinhood-rpc.publicnode.com, https://robinhood.drpc.org, https://rpc-robinhood.blockmachine.io, https://rpc.nodeflare.app/robinhood/public, https://robinhood.api.pocket.network, https://robinhood-mainnet-rpc.blockreq.com/v1/rpc/public, https://robinhood-mainnet.gateway.tatum.io, https://rpc-robinhood.globalstake.io, https://4663.rpc.thirdweb.com, https://robinhood.rpc.blxrbdn.com. All are rate-limited and some refuse eth_getLogs; the table on this page shows which, and is re-probed every 30 seconds.

What is the Robinhood Chain chain ID?

4663, or 0x1237 in hex. Use it in wallet_addEthereumChain, viem's defineChain or a Hardhat network entry.

How do I add Robinhood Chain to MetaMask?

Open the network selector, choose "Add a custom network" and enter: network name Robinhood Chain, RPC URL https://rpc.mainnet.chain.robinhood.com, chain ID 4663, currency symbol ETH, block explorer https://robinhoodchain.blockscout.com. With an injected wallet, the "Add to wallet" button on this page fills the form for you.

Is Robinhood Chain EVM-compatible?

Yes. Robinhood Chain is an Arbitrum Orbit chain, so it runs the EVM. Solidity contracts, the usual tooling, ERC-20 tokens and the Uniswap v2, v3 and v4 deployments work as on any EVM network. Two differences matter: block.number returns an Ethereum block estimate (use ArbSys.arbBlockNumber() for the chain's own), and the contract size limit is 96 KB.

What is the gas token on Robinhood Chain?

ETH (Ethereum, 18 decimals). Gas is paid in ETH; the WETH contract is 0x0bd7d308f8e1639fab988df18a8011f41eacad73.

What is the Robinhood Chain block explorer?

Blockscout at https://robinhoodchain.blockscout.com is the explorer Robinhood Chain's documentation lists. RobinScan at https://robin.etherscan.io, Etherscan's explorer for the chain, is a third-party alternative; Vectr's contracts are verified there and this site's address links point to it.

Does Robinhood Chain have Uniswap?

Yes: Uniswap v2, v3 and v4 and UniswapX are all deployed. The v4 PoolManager is 0x8366a39cc670b4001a1121b8f6a443a643e40951. On v3 the factory is 0x1f7d7550b1b028f7571e69a784071f0205fd2efa, SwapRouter02 0xcaf681a66d020601342297493863e78c959e5cb2, QuoterV2 0x33e885ed0ec9bf04ecfb19341582aadcb4c8a9e7 and NonfungiblePositionManager 0x73991a25c818bf1f1128deaab1492d45638de0d3; Vectr graduations mint a full-range v3 position at the 1% fee tier.

Where do the Stock Tokens on Robinhood Chain come from?

Robinhood Assets (Jersey) Limited issues them: tokenised debt securities that give economic exposure to US shares and ETFs, as plain ERC-20s on the chain, without rights in the underlying securities. The registry is GET https://api.robinhood.com/rhj/assets, mirrored with USD prices at https://api.vectr.bot/stocks. Each token carries a multiplier that folds splits and dividends into its value instead of rebasing balances.

Is there a Robinhood Chain WebSocket RPC?

Not from Robinhood: its only public endpoint is the HTTPS RPC. wss://feed.mainnet.chain.robinhood.com and its backup wss://delayed-feed.mainnet.chain.robinhood.com are sequencer feeds that a Nitro node reads, not JSON-RPC, so eth_subscribe does not work on them. For eth_subscribe over WebSocket use a provider: Alchemy, QuickNode, Chainstack, dRPC, Dwellir and Tatum all offer one for chain 4663.

What is the Robinhood Chain testnet chain ID?

46630. The testnet RPC is https://rpc.testnet.chain.robinhood.com and its explorer is https://explorer.testnet.chain.robinhood.com. Robinhood's docs name no faucet; QuickNode and Alchemy run testnet faucets.

How long does Robinhood Chain take to finalise a transaction?

Soft confirmation from the sequencer is sub-second. Batches are posted to Ethereum within minutes and reach Ethereum finality about 13 minutes after posting. Withdrawals to Ethereum wait out a 7-day challenge period.

Is Vectr affiliated with Robinhood?

No. Vectr is an independent token launchpad built on Robinhood Chain. Vectr is not affiliated with, endorsed by, or officially connected with Robinhood Markets, Inc.
