How do I add Robinhood Chain to MetaMask?
Add a custom network with RPC URL https://rpc.mainnet.chain.robinhood.com, chain ID 4663, currency symbol ETH, and block explorer https://robinhoodchain.blockscout.com. Robinhood Chain is EVM-equivalent, so no other configuration is needed.
In MetaMask: Settings → Networks → Add network → Add a network manually, then enter the four values above. The public RPC is rate-limited; if you are building an application rather than just holding tokens, use a dedicated endpoint instead.
One caveat worth knowing: a wallet showing your stock token balance is showing the raw ERC-20 amount. Because corporate actions are expressed through a multiplier rather than by minting or burning, that number will not change across a stock split even though your position has.
