Robinhood Chain RPC, Chain ID 4663 and Network Details

Everything on this page is public information, but where you copy it from matters. Lookalike RPC endpoints are a known phishing pattern on every new chain, and a malicious RPC can show you fabricated balances and quotes.

The network fields

What kind of chain this is

Robinhood Chain is built on Arbitrum Dedicated Blockchains — an Orbit rollup — and settles to Ethereum, inheriting its security. It produces a block roughly every 100 milliseconds and uses a first-come, first-served sequencing model for predictable ordering. Mainnet launched 1 July 2026.

It is fully EVM-compatible: Solidity and Vyper contracts deploy unmodified, and Hardhat, Foundry, ethers.js, viem and Wagmi all work out of the box. It also has first-class ERC-4337 account abstraction support, so gas sponsorship, batching and session keys are available natively.

When the public RPC is not enough

The public endpoint is fine for a wallet. It is not fine for an indexer, a bot or anything that needs archive state or a serious rate limit.

• Alchemy — the recommended provider, also supplying the Data API and gasless transaction infrastructure.
• QuickNode — low-latency JSON-RPC, full archive with debug and trace, plus real-time Streams.
• Chainstack, Dwellir, dRPC, Blockdaemon, Validation Cloud — all support the chain; compare on archive depth, rate limits and regional latency.
• Bitquery and Goldsky — for indexed data rather than raw RPC. Goldsky has indexed the chain since launch and is used by Uniswap, Privy, Rainbow, LI.FI and Bubblemaps.

Adding the network to a wallet

Robinhood Wallet and OKX Wallet support the chain natively with no configuration. For everything else: open the network dropdown, choose add network manually, paste the five fields above, save, then switch. MetaMask, Rabby and Trust Wallet all follow the same pattern under their custom network menus.

Chainlist does this in one click and removes the chance of a typo in the RPC field, which is the most common setup error.

Checking whether the chain is the problem

Before assuming an app is broken, check the official status page at status.robinhoodchain.offchain.io. During the chain's early months a meaningful share of stuck-transaction reports traced back to chain or indexer status rather than to the application.

Why a bad RPC is a security problem

An RPC endpoint is how your wallet learns what is true. It reports your balances, estimates gas, and broadcasts your transactions. A malicious endpoint can lie about all three.

The realistic attack is not dramatic. It shows you a balance that is not there, or a quote that is not real, and lets you act on it. By the time the discrepancy surfaces you have already signed. This is why the RPC URL should come from official documentation or Chainlist, and never from a message.

Choosing a provider for real workloads

The public endpoint is rate-limited and not archival. That is fine for a wallet and inadequate for anything that reads history or runs continuously.

• Archive access — needed for any historical query. Ask explicitly; 'full node' does not imply archive.
• debug and trace methods — required to reconstruct what a transaction did internally. Not all providers expose them.
• Rate limits and burst behaviour — the published limit matters less than what happens when you exceed it.
• Regional latency — for anything latency-sensitive, the nearest endpoint beats the best-specified one.
• Websocket or streaming support — polling for new blocks at 100ms block times is a losing design.

Building on the chain: the practical notes

Because this is an Arbitrum Orbit rollup with full EVM compatibility, Solidity and Vyper contracts deploy unmodified and the standard toolchain — Hardhat, Foundry, ethers.js, viem, Wagmi — works without adaptation. The testnet at chain ID 46630 mirrors mainnet for integration work.

The feature worth designing around is first-class ERC-4337 account abstraction. Gas sponsorship, transaction batching and session keys are available natively, which on a chain aimed at users arriving from a brokerage app rather than from crypto is arguably the most important capability it has.
