TLDR
- ARB rose about 7.6% after the Arbitrum fee-sharing update.
- Robinhood Chain will send 10% of net protocol fees to Arbitrum.
- Arbitrum DAO treasury will receive 8% of shared chain fees.
- The Arbitrum Developer Guild will receive 2% of shared fees.
- Robinhood Chain processed 4M transactions in its first mainnet week.
ARB rose more than 7% after Offchain Labs said Robinhood Chain and other Layer 2 networks using Arbitrum technology will send 10% of net protocol revenue back to the Arbitrum ecosystem.
The model applies to chains built with the Arbitrum tech stack that settle outside Arbitrum One or Nova. Under the split, 8% of net protocol revenue goes to the Arbitrum DAO treasury, while 2% goes to the Arbitrum Developer Guild.
Offchain Labs co-founder Steven Goldfeder said, “As enterprise adoption is heating up, Arbitrum is well positioned to capture revenue.” He added that “100% of fees collected on Arbitrum One go to the Arbitrum treasury.”
Robinhood Chain Joins Arbitrum Fee Model
Robinhood Chain is one of the highest-profile networks covered by the Arbitrum Expansion Program. The chain uses Arbitrum’s technology and has moved from a public testnet in February to full mainnet operation.
The chain processed about 4 million transactions during its first week on mainnet. Uniswap was integrated from day one, giving users access to decentralized exchange infrastructure at launch.
Robinhood had already used Arbitrum One in 2025 to deploy tokenized US stocks and ETFs. Its new dedicated chain shows how a financial platform can move from using an existing Layer 2 to operating its own network on the same tech stack.
Goldfeder said Robinhood Chain and other Arbitrum-based L2s will share 10% of collected fees with the ecosystem. The share will support the tokenholder-controlled treasury and fund development work.
Arbitrum Expansion Program Adds Revenue Share
The Arbitrum Expansion Program is designed for chains that use Arbitrum technology but settle outside Arbitrum One or Nova. Revenue subject to sharing mainly comes from sequencer profits, which are fees earned by the system that orders and processes transactions.
If a chain uses Timeboost, Arbitrum’s mechanism for capturing maximal extractable value, those revenues may also fall under the sharing model. The structure creates a direct link between new Arbitrum-based chains and the broader ecosystem.
The 8% treasury allocation gives ARB holders governance control over funds returned from ecosystem growth. The 2% share for the Developer Guild is meant to support teams building and maintaining the technology.
The approach also mirrors a broader trend among Layer 2 ecosystems. Optimism uses a similar model with its OP Stack and Superchain, where chains using the stack send revenue back to the wider Optimism ecosystem.
ARB Price Gains After Fee Announcement
ARB traded above $0.081 after the announcement, erasing losses from earlier in the week. The token rose about 7.6% as traders reacted to the fee-sharing details and Robinhood Chain integration.
The price move reflected renewed attention on how Arbitrum-based networks may return value to the DAO treasury. The model does not guarantee token price gains, but it gives the ecosystem a clearer revenue path tied to adoption.
For ARB holders, the key change is that external chains using Arbitrum’s technology can now contribute funds to the DAO treasury. That may matter if more fintechs, exchanges, or institutions launch dedicated chains on the Arbitrum stack.
Robinhood Chain’s early transaction count gives the market a first data point for how large those networks could become. Future revenue will depend on user activity, fees, sequencer margins, and whether more enterprise chains join the Arbitrum Expansion Program.
