Network

Robinhood Chain network details, including chain IDs, RPC endpoints, explorers, and how to override the RPC.

Robinhood Chain is an Arbitrum Orbit L2 with full EVM compatibility. ETH is the gas token, and standard Ethereum tooling works unchanged. The app targets mainnet; the tables below list both mainnet and testnet parameters.

Mainnet

FieldValue
Network nameRobinhood Chain
Chain ID4663 (0x1237)
RPC URLhttps://rpc.mainnet.chain.robinhood.com
Explorerhttps://robinhoodchain.blockscout.com
Gas tokenETH (18 decimals)

Testnet

FieldValue
Network nameRobinhood Chain Testnet
Chain ID46630
RPC URLhttps://rpc.testnet.chain.robinhood.com
Explorerhttps://explorer.testnet.chain.robinhood.com
Gas tokenETH (18 decimals)

The deployed app is configured for mainnet only. To use it against testnet, self-host and override the RPC as shown below (and point your wallet at chain ID 46630).

Explorer

The explorer is a Blockscout instance. Several tools use its REST API (v2, under /api/v2/) to read verified-contract ABIs and names. For example, the Contract Interactor fetches an ABI for you, and the Approval Manager resolves spender contract names. Address, transaction, token, and block links throughout the app point here.

Multicall3

Multicall3 is deployed at the canonical address 0xcA11bde05977b3631167028862bE2a173976CA11. Tools that read many values at once (the Batch Balance Checker, token-metadata lookups, allowance scans) batch their calls through it, so a large read is a single RPC round-trip.

Overriding the RPC

The public RPC is rate-limited. If you are self-hosting and want to use a dedicated provider, set the NEXT_PUBLIC_RPC_URL environment variable to your endpoint:

NEXT_PUBLIC_RPC_URL=https://your-provider.example/robinhood-chain

When unset, the app falls back to the public mainnet RPC. This is the only value needed to change where reads and transaction broadcasts are sent; nothing else in the app hardcodes a URL. See Security for the full list of environment variables.
