The L2 stack Robinhood Chain is built on — and takes a revenue cut from.
- The stack
- Robinhood Chain is a dedicated Arbitrum chain built on the Arbitrum stack (Orbit / Dedicated Chains, Nitro), settling to Ethereum.
- Expansion Program revenue share
- Under the Arbitrum Expansion Program the chain routes 10% of net protocol revenue to the Arbitrum ecosystem.
- Revenue split
- Of that 10%, a reported 8% goes to the Arbitrum DAO treasury and 2% to the Arbitrum Developer Guild.
- Inherited properties
- The chain's EVM tooling, ~100ms blocks and Ethereum settlement are properties of the Arbitrum stack rather than bespoke design.
The canonical Arbitrum-native bridge between Ethereum and Robinhood Chain, with a 7-day withdrawal challenge.
- What it is
- The canonical route between Ethereum and Robinhood Chain, inherited from the Arbitrum stack. Trustless — security comes from Ethereum, not third-party validators.
- Deposit time
- Deposits from Ethereum to Robinhood Chain confirm within minutes via the Arbitrum portal.
- Withdrawal time
- Withdrawing to Ethereum is a three-step process gated by Arbitrum's standard 7-day challenge period, after which funds are claimed with an L1 transaction (and L1 gas).
- TVL
- Roughly $143m in early July 2026 (DefiLlama) — the largest single pool of assets connected to the chain.
