Robinhood Chain, an Arbitrum-powered blockchain launched July 1, has surpassed 100 million cumulative transactions within its first three weeks of operation, according to Robinhood's newsroom.
The milestone places the blockchain among the fastest-growing dedicated chains by transaction volume. During the first three weeks, the network processed roughly 10 million transactions daily, with block times declining to 100 milliseconds, according to data posted by the project.
Robinhood launched its own blockchain to accelerate trading and settlement for stock tokens and crypto assets on the Arbitrum L2. The chain operates as an Arbitrum Orbit rollup, a configuration that allows projects to deploy their own execution layer while relying on Arbitrum's shared sequencer and settlement guarantees. Arbitrum said in a forum post that the arrangement lets Robinhood optimize for its trading use case without managing full infrastructure independently.
The 100 million transaction count in 21 days translates to roughly 4.76 million transactions per day on average. For context, Arbitrum itself processed roughly 900,000 daily transactions in mid-2026 before Robinhood's launch. Polygon, a larger Layer 2 network, averaged around 3 million daily transactions over the same period.
Robinhood began offering stock token trading on its blockchain, allowing users to hold fractional equities as crypto assets. The company has also integrated agentic trading capabilities, letting users set automated trading parameters through AI-powered agents.
The number that decides whether this growth translates to sustainable activity is whether daily active users on Robinhood Chain remains above 50,000 by the end of the third month of operation.
