Connect to the network

Robinhood Chain supports Ethereum-compatible wallets and clients. The public network settings are:

  • Mainnet: chain ID 4663 (0x1237), RPC https://rpc.mainnet.chain.robinhood.com, explorer https://robinhoodchain.blockscout.com.
  • Testnet: chain ID 46630 (0xb626), RPC https://rpc.testnet.chain.robinhood.com.

ETH is the gas currency. Robinhood's public RPC is rate-limited and its terms describe it as unsuitable for production use. Applications with production traffic should select a provider and review its service limits.

Deploy and test with Ethereum tools

The chain runs Arbitrum Nitro. Foundry and Hardhat support contract development, while ethers.js, viem and Wagmi provide client integrations. Solidity and Vyper contracts can target its EVM environment.

Compatibility does not mean every operational detail is identical to Ethereum L1. Check the chain documentation for contract-size limits, block semantics and transaction ordering. ETH remains the native gas asset, so applications can use msg.value, BALANCE and payable functions. Test behavior on the intended network before relying on an Ethereum deployment's assumptions.

Account abstraction

Robinhood publishes ERC-4337 EntryPoint and SenderCreator addresses for versions v0.6, v0.7 and v0.8. EIP-7702 delegation is also supported, allowing compatible account software to add functions such as batching or sponsorship without requiring a new account address.

A working integration still needs the appropriate bundler, paymaster or wallet implementation. Alchemy provides RPC and account-abstraction tooling; listed node providers also include QuickNode, Blockdaemon, dRPC and Validation Cloud. Confirm that the selected service supports the network and contract version used by your application.

Frequently asked

What are the mainnet and testnet RPC settings?
Mainnet uses chain ID 4663 (0x1237) and https://rpc.mainnet.chain.robinhood.com. Testnet uses 46630 (0xb626) and https://rpc.testnet.chain.robinhood.com. Gas is paid in ETH.
Can I use Foundry, Hardhat and viem?
Yes. Robinhood Chain supports Ethereum tooling. Check its technical differences and test the application on the target network.
Which account-abstraction versions are documented?
The registry publishes ERC-4337 EntryPoint and SenderCreator addresses for v0.6, v0.7 and v0.8, and the chain supports EIP-7702 delegation. Service compatibility must be checked separately.
