Arbitrum Token Sees 8% Jump as Robinhood Chain Taps Fee-Sharing Model

The Arbitrum token ARB saw an 8% price surge following the launch of Robinhood Chain, a permissionless Ethereum Layer-2 built on Arbitrum's Orbit technology stack.

Rozbeh Sharifi, whose view is not represented in this article, was unavailable for comment. Offchain Labs, the company behind Arbitrum's core technology, introduced a new revenue-sharing structure that funnels 10% of net protocol fees generated by chains built using Arbitrum's infrastructure back into the ecosystem.

This includes Robinhood Chain, which launched its public mainnet on July 1 and processed over 4 million transactions in its first week. The fee-sharing model splits the revenue into two buckets: 8% goes to the Arbitrum DAO treasury, while 2% funds builders working on Arbitrum tooling and applications.

The launch marks another significant milestone for Robinhood's blockchain presence, which has been building since 2024. The company initially tested tokenized stock offerings on the Arbitrum network in 2025 before committing to its own chain.
