What is the Robinhood Chain chain ID?

4663 (hex 0x1237) for Robinhood Chain mainnet. The testnet uses 46630.

Is 4663 Robinhood Chain mainnet or testnet?

Mainnet. The testnet is a separate network with chain ID 46630, its own public RPC and its own explorer; a config that mixes the two fails the chain ID check.

How do I add Robinhood Chain to MetaMask?

Add a network manually with chain ID 4663 (0x1237), currency ETH, the Triport RPC URL in its keyed form and the Blockscout explorer. The MetaMask tab above produces the exact wallet_addEthereumChain payload.

Why does the RPC URL contain my key instead of a header?

Wallets, hardhat.config and foundry.toml cannot send a custom header, so they use the keyed URL form. Server-side code should send the x-token header instead and keep keys out of URLs and logs.

Can I use a Triport URL without a key?

One: https://triport.io/public/robinhood, the keyless test URL — 15 req/s of reads and 3 req/s of sends shared by every caller, no WebSocket. The keyed URLs answer HTTP 401 without their key, so a wallet cannot read the chain ID through them. The network's own public RPC, https://rpc.mainnet.chain.robinhood.com, is keyless too and documented as rate-limited and not recommended for production use.

Is my key sent to Triport when I use this page?

No. The snippets are generated in your browser: the key is never submitted, never stored and never written into the page URL, which is why this tool has no shareable link.

Where do I get ETH for gas?

Gas on Robinhood Chain is paid in ETH that you bridge in — the canonical route deposits from Ethereum L1, and partner bridges exist. The Getting ETH for gas page in the Robinhood Chain documentation lists the routes.

Does this work for the Robinhood testnet?

No. Testnet chain 46630 exists publicly, but Triport publishes mainnet (4663) only — point test work at the network's own testnet endpoint.

Network values

Robinhood Chain mainnet connection values
Network name	`Robinhood Chain`
Chain ID	`4663 (0x1237)`
Currency symbol	`ETH` — getting ETH for gas
RPC URL (header auth)	`https://triport.io/rpc/robinhood`
RPC URL (keyed, for wallets and config files)	`https://triport.io/r/<API_KEY>/robinhood`
WebSocket URL (keyed)	`wss://triport.io/ws/robinhood/<API_KEY>`
Triport keyless public URL	`https://triport.io/public/robinhood` — 15 req/s reads, 3 req/s transaction sends — one budget shared by every caller; no key, no WebSocket
Block explorer	`https://robinhoodchain.blockscout.com`
Public RPC (network-operated)	`https://rpc.mainnet.chain.robinhood.com` — no key, rate-limited; Robinhood Chain public RPC vs a keyed endpoint
Testnet	Chain ID `46630` (`0xb626`) — not served by Triport; values in Robinhood Chain testnet

Chain ID, currency, explorer and the public URL are the values the network publishes; the Triport URLs need an API key. Endpoints and plans: Robinhood Chain RPC endpoint.

Generate your config

API key (optional — without one the button adds the keyless public URL; the key stays in this tab and goes only to your wallet)

Adds https://triport.io/public/robinhood with chain ID 0x1237 through wallet_addEthereumChain (EIP-3085).

Your API key (optional — stays in this browser tab, never sent anywhere and never added to the URL)

Keys in URLs vs headers

A keyed URL is the same credential as a header, in a less private place: it lands in shell history, CI logs and screenshots. Use it only where a header is impossible (wallets, hardhat.config, foundry.toml), send x-token from server code, and rotate a key that leaked.

Robinhood Chain testnet: Arbitrum Orbit testnet of Robinhood Chain; its sequencer feed is wss://feed.testnet.chain.robinhood.com. Triport serves mainnet only. These values are for switching your config; they are not Triport endpoints. The network names no official faucet on its connecting page; the Robinhood Chain testnet guide: faucets and switching to 4663 (also Robinhood Chain explorers and bridge ETH to Robinhood Chain) covers getting test ETH and moving a config to mainnet.

Verify the connection

Call eth_chainId first: it must return 0x1237. Wallets reject a network whose chain ID disagrees with the configured value, so this one call explains most could not add network errors. Then read the quickstart for the first real request. Connected to the testnet by mistake? The same call answers 0xb626 there (chain ID 46630).

When the chain ID does not match

Symptom, cause and the check that settles it
Symptom	Likely cause	Check
eth_chainId returns something other than 0x1237	The URL points at a different network	Compare the URL with the table above; 0x1237 is the only mainnet answer
Hardhat or Foundry reports a chain ID mismatch	chainId 46630 (testnet) in the config while the URL is mainnet, or the reverse	Set chainId: 4663 for a mainnet URL; keep testnet values in a separate network entry
MetaMask cannot fetch the chain ID when you add the network	A keyed Triport URL without the key (HTTP 401) or a typo in the URL	Run the curl snippet against the same URL; use the keyed form for wallets
A keyed URL appeared in a screenshot, log or public repository	The key travelled with the URL	Rotate the key in the console and update every config that carried it
