Arbitrum's ARB token jumps 8% as Robinhood Chain launches with new fee-sharing model.

Robinhood Chain, a new Ethereum Layer-2 blockchain built on Arbitrum’s technology, launched its public mainnet on July 1, 2026, focusing on tokenized real-world assets and DeFi applications. The chain processes transactions quickly and uses ETH for gas fees, linking it to the Ethereum ecosystem. Robinhood Chain introduced a fee-sharing model where 10% of net protocol fees go back to the Arbitrum ecosystem, with 8% to the DAO treasury and 2% to the Developer Guild. This new revenue-sharing approach boosted the ARB token price by about 7.6%, signaling a shift from a governance token to a revenue-generating asset, offering new value for investors.
