Robinhood Chain, built on Arbitrum, posted record fees and boosted demand for ARB. Investors are now watching the September 16 unlock and the end of the gas subsidy.
Key Takeaways
- Arbitrum (ARB) rose 90% from its June low and is trading around $0.1316 after a 50% weekly gain.
- Robinhood Chain on Arbitrum hit a record $4.45 million in fees on September 2 and generated more than $10 million between August 31 and September 1.
- The market is watching the ARB unlock on September 16 and the end of Robinhood's 90-day gas subsidy later this month.
Arbitrum (ARB) has climbed 90% from the record low the token set in June. The rally picked up speed after Robinhood Chain hit a record $4.45 million in fees on September 2. ARB is now trading around $0.1316 (€0.11), after a 50% gain over the past week.
Robinhood Chain Draws Attention
Robinhood Chain runs on Arbitrum and launched in July. Uniswap handles most of the trading volume on that chain. Between August 31 and September 1, Robinhood Chain generated more than $10 million (€8.6 million) in fees, a 109% increase across the sessions. In August, daily fees were usually below $400,000 (€344,200), which puts the current pace more than ten times above the previous peak.
Under the Arbitrum Expansion Program, 8% of revenue from Orbit chains goes to ArbitrumDAO and 2% goes to a developer guild. Based on that share, about $320,000 (€275,300) would have gone to the DAO on September 2. Arbitrum One itself earned much less during the same period, despite 1.94 million transactions in 24 hours.
Arbitrum One Remains Cheap
The comparison with Arbitrum One shows how low fees are on the network. Average transaction fees are around $0.007, and Blockscout saw no pending transactions. The 0.242-second block time also leaves plenty of room for more Orbit chains.
Arbitrum One is an Ethereum Layer 2 that can handle far more transactions than Ethereum itself. The chain is fully EVM-compatible, which means developers can use existing Solidity contracts without making changes. That makes the network especially useful for projects that want to build quickly and cheaply while still settling on Ethereum.
What This Means for ARB
For European crypto readers, the key point is that activity on a young chain does not automatically lead to more value on the main chain. Arbitrum's total value locked is around $1.37 billion (€1.2 billion), still well below the peak above $4 billion (€3.4 billion) in October 2025. At the same time, the market is still closely watching the upcoming ARB unlock on September 16 and the end of Robinhood's 90-day gas subsidy later this month.
That fits into a broader market where investors are increasingly looking at usage and fee generation. In that context, fundamentals have become more important than price momentum alone.
Technically, the picture is still positive for now, but the move has cooled off. ARB is trading around $0.132 (€0.11), after pulling back from the recent high near $0.145 (€0.12). The first major support is around $0.125 (€0.11) to $0.127 (€0.11), while a break above $0.140 (€0.12) to $0.145 (€0.12) could open the door toward $0.150 (€0.13).
