Arbitrum volume surges following Stylus implementation

Computational gains from Stylus

Offchain Labs released the Stylus mainnet for Arbitrum One and Arbitrum Nova in August 2026. This update adds a WebAssembly-based proving environment to the existing Nitro stack. Users deploy programs written in Rust, C, or C++ alongside Solidity contracts. The dual-VM design allows these multi-language contracts to interact with the Ethereum Virtual Machine. You already know that Solidity limitations restrict high-compute applications. The dual-VM architecture allows Stylus contracts written in Rust to call existing Solidity dApps, which ensures that developers maintain full interoperability with the Ethereum Virtual Machine while they execute computationally intensive logic at near-native speeds. Developers use the Rust SDK to manage storage and handle types. The compiler translates WASM bytecode into optimized machine instructions. This process removes the interpretation overhead found in traditional EVM execution. WASM provides a stable foundation for bringing diverse development communities into the blockchain space. Because WASM can be compiled to native machine code, it delivers performance that approaches non-virtualized applications.

Metric	Stylus Performance
Execution Speed	10x faster than Solidity
Memory Efficiency	100 to 500 times greater
Supported Languages	Rust, C, C++

The execution speed exceeds Solidity by an order of magnitude. This efficiency helps developers build cryptography libraries or machine learning applications. Because the system relies on a single-party sequencer, the network still presents an operational centralization risk.

Revenue from the Expansion Program

Robinhood Chain went live on the Arbitrum mainnet on 1 July 2026. It operates through the Arbitrum Expansion Program. This program requires external chains to return 10% of net protocol revenue to the Arbitrum ecosystem. In July, licensing fees from the Expansion Program reached $360,000, an amount that accounted for 35% of the Arbitrum DAO monthly income. Robinhood Chain processed more than 200 million transactions during its public testnet phase. The chain’s daily DEX trading volume exceeded $1.5 billion in early September. Robinhood Chain uses the Orbit framework. Under the Expansion Program, 8% of revenue goes to the Arbitrum DAO treasury and 2% goes to the Arbitrum Developer Guild. The chain follows the issuance of tokenized stocks and ETFs on Arbitrum One from June 2025. The ecosystem generated $206 million in GDP during the first half of 2026. The Arbitrum DAO accrued $6.19 million in income during the first half of 2026 from transaction fees, Timeboost, Expansion Program fees, and treasury income. The collective gross margin on protocol revenue exceeded 97% in the first half of the year. Standard Chartered estimated that Arbitrum could receive $5 million in Expansion Program fees during September.

Token supply and market pressure

The implementation of Stylus and the Expansion Program establishes Arbitrum as a broad infrastructure provider. Arbitrum faces a 92.65 million ARB token unlock. This batch of tokens carries a value of $18.2 million at a price of $0.197. The total circulating supply of ARB remains at 66.8% of the total supply. While the title notes a $2.8 billion daily volume, Arbitrum DEX volume fell 68% between January and September 2026. This decline happened while the market capacity for the network remained high. ARB futures trading volume hit $2.15 billion in a 24-hour period. Open interest in these futures reached $308 million. The cumulative ecosystem income since launch reached $1.7 billion, and the Arbitrum Foundation holds ARB in its treasury. The final token vest arrives in March 2027. The market cap for ARB exceeded $1.3 billion in early September, while 9.23 billion ARB tokens were unlocked or held in the treasury as of 17 August 2026. The price of ARB approached $0.197 on September 6; this marked a 127% gain since August 30. Does the demand from Robinhood Chain offset the 92.65 million token unlock?
