Robinhood Chain

Robinhood Chain is a permissionless Ethereum Layer-2 built as an Arbitrum Dedicated Blockchain. It is EVM-compatible, gas is paid in ETH, mainnet chain ID is 4663, and sequencing is first-come-first-served — paying more does not let you cut the line. The official docs say the network is live.

It is not a new L1, not “hoodie chain,” and not Ethereum’s Hoodi testnet. Chain ID 4663 with ETH as the native token is how you know a wallet prompt is pointing at the real thing.

Koi is not Robinhood. Nothing here is an offer, a listing, or a promise that Koi will ship a product on this chain. These notes exist because the official pages are thin and most of what ranks is Robinhood quoting itself.

Network details

Public RPCs are rate-limited. Robinhood points builders at Alchemy — and lists QuickNode, Blockdaemon, dRPC, and Validation Cloud — for anything that has to stay up. Add the network to a wallet if you only need to look around.

How the chain is put together

Underneath, it is an Arbitrum Dedicated Blockchain settling to Ethereum and using blobs for data availability: the ordinary Orbit / Nitro arrangement, with execution on L2, security inherited from Ethereum, and withdrawals that have to wait out a challenge period.

Account abstraction is first-class (ERC-4337). Solidity and Vyper deploy without a special SDK. Hardhat, Foundry, ethers, viem, and Wagmi all work. If a tool speaks JSON-RPC, it can speak to this chain.

What people are actually using it for

Robinhood’s own framing is tokenized real-world assets — equities, ETFs, private assets — held in a wallet and moved 24/7. The flagship asset is Stock Tokens, which are not the same thing as owning the stock. Read Robinhood Stock Tokens and the section below before repeating a tweet about them. Category background: what RWA means and tokenized stocks.

The rest of the surface looks like any new L2: a Uniswap deploy, Morpho for lending, Paxos USDG, LayerZero for bridging, Chainlink for prices. Official ecosystem notes also list Lighter and Arcus for perps. Appearing on Robinhood’s partner table is not an endorsement, and it is not one from us either.

Memecoin launchpads turned up in search the week the chain got loud. That demand is real and messy, and a launchpad is still not “the chain.” A factory contract is not infrastructure. How creating a memecoin actually works — Koi has not announced a launchpad.

Stock tokens, said plainly

Robinhood Stock Tokens are ERC-20s issued by Robinhood Assets (Jersey) Limited. They give economic exposure to an underlying share or ETF. They do not give you legal or beneficial rights in that security, or any claim against its issuer. Robinhood’s own documents describe them as tokenised debt securities.

They are not registered under US securities law and may not be offered or sold to US persons. Canada, the UK, and Switzerland are restricted too. Only authorised participants mint from the issuer; everyone else composes with tokens that already exist.

For the legal text, read Stock Tokens and the RHJ documents. We are not going to paraphrase a prospectus into a buy button.

Getting ETH and other assets onto the chain

The default path is the canonical Arbitrum bridge: Ethereum in, Robinhood Chain out, roughly ten minutes on deposit. Withdrawals are the familiar three-step Nitro flow — initiate on L2, wait ~7 days, claim on L1. How bridging works. To move funds now, bridge or fund Robinhood Chain.

Faster routes exist (LayerZero / Stargate, Chainlink CCIP, Relay, Across, LI.FI). Faster almost always means trusting a different mechanism than the canonical bridge. Robinhood’s bridging page is the list. Testnet ETH comes from the testnet faucet.
