Offchain Labs co-founder Steven Goldfeder says every Arbitrum-based Layer 2, not just Arbitrum One, will now route a fee cut back to the ARB treasury.
Arbitrum will collect 10% of fees generated on Robinhood Chain and every other Layer 2 built on its technology stack, Offchain Labs co-founder Steven Goldfeder said Wednesday on X. Of that cut, 8% goes to the tokenholder-controlled Arbitrum treasury and 2% funds development, he said.
Goldfeder framed the fee-sharing model as a revenue play tied to enterprise growth.
“As enterprise adoption is heating up, Arbitrum is well positioned to capture revenue,” he wrote, adding that Arbitrum One, the flagship rollup, sends 100% of its own fees to the treasury.
The disclosure clarifies how Arbitrum’s Orbit framework, the toolkit third parties use to launch custom Layer 2 and Layer 3 chains on Arbitrum’s stack, monetizes for ARB holders beyond the base chain.
Robinhood Chain, an Ethereum Layer 2 built on that stack, launched its mainnet July 1, adding tokenized stocks, onchain lending and agentic trading inside Robinhood’s app. The Defiant first reported Robinhood’s partnership with Arbitrum in February 2024.
An 8% treasury cut on external Orbit chains gives ARB a direct claim on fee volume generated outside Arbitrum’s own network, a structural shift from a chain that previously monetized only its own base-layer activity. The arrangement extends to any Orbit-based L2, not Robinhood Chain alone, per Goldfeder’s post.
The disclosure comes as Robinhood Chain sees early bridging activity, with several onchain trackers noting a sharp rise in ETH bridged to the new network in its first days live.
