Arbitrum just unlocked a fresh revenue engine as the Layer-2 arms race intensifies: fees from Robinhood Chain—and any other L2s built on Arbitrum’s stack—will funnel a slice of earnings back into the Arbitrum ecosystem.
What changed
- Offchain Labs co-founder Steven Goldfeder confirmed that 10% of protocol net revenue generated by chains in the Arbitrum Expansion Program (i.e., chains deployed outside Arbitrum One) will be returned to Arbitrum’s ecosystem. That split is 8% to the tokenholder-controlled Arbitrum DAO treasury and 2% to the Arbitrum Developer Guild for development funding.
- Goldfeder also said 100% of fees collected on Arbitrum One go to the Arbitrum treasury.
- The DAO factsheet frames the payout as a share of “protocol net revenue,” meaning the calculation comes after network costs rather than from every user payment—helpful for apples-to-apples revenue comparisons across partner chains.
Why this matters
- The update gives Arbitrum a clear, recurring revenue route as major outfits build on its tech. Corporate-branded L2s like Robinhood Chain are part of a wider trend (alongside networks such as Base) in which companies launch their own blockspace while leveraging established rollup technology.
- By tying enterprise adoption directly to ecosystem funding, Arbitrum can channel real-world usage into resources for tokenholders and builders—improving long-term sustainability and developer incentives.
Robinhood Chain: what’s live now
- Robinhood Chain moved from testnet to mainnet and went live on July 1 as a dedicated Arbitrum chain that settles to Ethereum, according to the Arbitrum DAO factsheet and reporting shared by Wu Blockchain.
- Users can bridge assets from Solana, Ethereum, Arbitrum and other networks into Robinhood Chain via Robinhood Wallet and execute swaps inside the app.
- Robinhood has emphasized tokenized stocks as a core product for the new chain: eligible users across more than 120 countries can trade tokenized equities via Robinhood Wallet and supported DEXs.
- The testnet saw heavy activity—over 4 million transactions in its first test week—as developers trialed tokenized stocks and DeFi tools before launch.
- Robinhood also rolled out related products including perpetual futures for eligible European users, Stock Tokens, Robinhood Earn and plans for AI-linked trading accounts. Infrastructure partners include Uniswap (supporting a dedicated AMM) and other providers handling data, custody and on-chain routing.
The takeaway
Arbitrum has converted enterprise adoption into an income stream that supports its DAO and developer ecosystem. The real proof will be steady, sustained usage on partner chains: if Robinhood Chain drives ongoing trading, swaps and lending, those activities could translate into meaningful recurring revenue for Arbitrum’s treasury and developer funds—strengthening the protocol’s position in the competitive L2 landscape.
