A Layer 2 for financial applications
Robinhood Chain is an EVM-compatible Layer 2 built on the Arbitrum stack and settled to Ethereum. Public mainnet launched on 1 July 2026 with chain ID 4663, following a February 2026 testnet that Robinhood and Arbitrum reported had processed more than 200 million transactions.
The network supports tokenized equities, stablecoins, lending, perpetuals and applications that automate trading. Developers can deploy contracts and integrate existing onchain assets. Each application has its own operator, permissions and terms.
Architecture and transaction ordering
Robinhood Chain is an optimistic rollup running Arbitrum Nitro. A Robinhood-operated sequencer orders transactions into roughly 100ms blocks, then posts batches to Ethereum. Ethereum blobs carry transaction data used to reconstruct the chain's state.
The sequencer uses first-come, first-served ordering by arrival time, without a priority-fee auction. ETH pays for gas. Ethereum-compatible wallets and tools can connect, while ERC-4337 and EIP-7702 support account abstraction. Integrators should check the chain documentation for technical differences from Ethereum.
ETH gas and network economics
Robinhood Chain uses ETH for gas and has no separate native chain token in the documented network design. The existing launch materials do not announce a staking token, governance token or chain airdrop.
Network revenue comes through sequencing, with an Arbitrum Expansion Program agreement directing a share of net protocol revenue to the Arbitrum ecosystem. That arrangement is separate from the shares, Stock Tokens or other assets a user may hold.
Application access and network control
Open contract deployment lets independent developers build applications and issue tokens. It also means a token's presence on the network is not evidence of Robinhood approval.
Robinhood operates the sequencer and public RPC. Those operational dependencies remain relevant even though transactions settle to Ethereum. Permissioned validators and a Security Council have separate roles in checking assertions and approving protocol changes. See the network architecture reference for the current arrangements and its source links.
