Robinhood’s Custom L2 Hits 4 Million Testnet Transactions, Commits $1M to Arbitrum Hackathons
Robinhood Chain testnet processed 4 million transactions in its first week following its Feb. 10 public launch. The Arbitrum-based L2 targets tokenized stocks and on-chain financial services and secures $1 million for 2026 Arbitrum hackathons ahead of a mainnet launch later this year.
1. Testnet Launch and Performance
Robinhood unveiled its Arbitrum-based Chain testnet on Feb. 10 and saw 4 million transactions in the first week. Developers can connect wallets, deploy smart contracts and experiment with simulated stock tokens like Tesla and Amazon using test ETH in a sandbox environment.
2. Ecosystem Support and Funding
Key infrastructure providers including Alchemy, Chainlink, LayerZero and TRM Labs have integrated services to support development on the testnet. Robinhood has pledged $1 million to the 2026 Arbitrum Open House program to fund buildathons and founder events in New York, Dubai, London and Singapore.
3. Strategic Positioning for Mainnet
The custom L2 is designed for regulated finance with a focus on real-world assets and on-chain services, leveraging Ethereum tooling compatibility. Robinhood aims to transition from testnet to a full mainnet launch later in 2026 as it pushes into tokenized finance.
