Robinhood Chain Fees To Boost Arbitrum

Offchain Labs, the developer behind Arbitrum, has confirmed that 10% of net protocol fees generated by Robinhood Chain and other Layer 2 networks built on the Arbitrum tech stack will be directed back into the Arbitrum ecosystem.

How the Fee Split Works

The split breaks down to 8% flowing into the Arbitrum DAO treasury and 2% going to the Arbitrum Developer Guild. The arrangement falls under the Arbitrum Expansion Program (AEP). Any Arbitrum chain deployed outside of Arbitrum One and Arbitrum Nova must pay 10% of its protocol net revenue to the Arbitrum Foundation under the AEP licence.

The Developer Guild incentivizes developers contributing to the Arbitrum codebase, with the 2% allocation going to a fund dedicated to this purpose. For $ARB token holders, the revenue-sharing model ties value accrual directly to ecosystem growth, creating a more durable incentive than one-time grants.

Robinhood Chain Goes Live

Alongside the fee arrangement, Robinhood Chain has launched inside Robinhood Wallet with cross-chain bridging and swap support now available to users. The public mainnet launched on July 1, 2026, announced at Robinhood's "The World is Flat" keynote at the Old Royal Naval College in London, after a public testnet that recorded 4 million transactions in its first week.

Robinhood Chain is an Ethereum Layer 2 blockchain built on the Arbitrum stack, designed for tokenized real-world assets and 24/7 financial services. Day-one partners include Uniswap, deploying a dedicated AMM as the primary public liquidity protocol, with deep integrations from Alchemy, BitGo, and Chainlink giving the chain fast block times and out-of-the-box DeFi primitives such as lending and borrowing.

Robinhood's path to this point included an earlier phase where the company deployed tokenized US stocks and ETFs on Arbitrum One in 2025. The Arbitrum-based Layer 2 focuses on tokenized stocks, real-world assets, and on-chain financial services.
