Robinhood Chain chain ID (4663)
A chain ID is a numeric identifier that EVM wallets and applications use to distinguish one network from another and to sign transactions that cannot be replayed on a different chain. For Robinhood Chain the chain ID is 4663, as published in the Robinhood Chain documentation.
When you "switch networks" in MetaMask, Rabby or WalletConnect, the wallet is really matching a chain ID to an RPC URL and a native currency. Getting the chain ID wrong is one of the most common causes of failed transactions and "wrong network" errors on chain 4663.

How the ID is used
Wallets bind the chain ID to a network profile (name, RPC URL, gas token symbol, explorer URL). Every signed transaction includes the chain ID inside its signature, which is why a transaction signed for chain 4663 cannot be executed on Ethereum mainnet or any other EVM chain.
How to interpret it
Read the chain ID as the network's phone number. If a wallet says it is on chain 4663, it is talking to Robinhood Chain — even if the human-readable name is misspelled. If it says any other number, calls to the RPC or contract will not reach chain 4663.
Caveats
The chain ID does not describe security, decentralisation, or Robinhood affiliation of any specific dApp on 4663. Third-party lists of chain IDs can lag docs updates; treat docs.robinhood.com as the source of truth if a directory disagrees.
Concrete example
A user pastes a Blockscout link into a dApp that only supports Ethereum mainnet (chain ID 1). The dApp shows "wrong network" because the wallet is set to 4663. Switching the wallet to chain 4663 in the network dropdown resolves it — no reinstall required.
Frequently asked questions
What is the chain ID of Robinhood Chain? The chain ID is 4663, per the Robinhood Chain documentation. It is the number wallets need to identify the network alongside its RPC URL. Can I invent a chain ID for Robinhood Chain? No. Only the docs-published value (4663) will actually reach Robinhood Chain. A wrong chain ID either fails to connect or, worse, sends a transaction to a different network entirely. Do I need the chain ID if I use a preset network in my wallet? Not if the preset is correct. If you add the network manually, the chain ID is required alongside the RPC URL for the wallet to accept the configuration.
