With so many tech stacks available, why did Robinhood choose to launch a chain on Arbitrum?
Once the experiment succeeds, the digital transformation of the entire multi-trillion-dollar TradFi markets—including bonds, futures, insurance, and real estate—will accelerate.

A brief take on the news that @RobinhoodApp plans to build a layer2 on Arbitrum:
1) From a technical standpoint, Robinhood's decision to align with Arbitrum's Nitro is no different from Coinbase’s earlier alignment with Optimism’s OP Stack. However, Base’s performance has already revealed an important pattern: the success of a tech stack does not equate to the success of its parent chain.
Base’s rise was largely driven by Coinbase’s brand power, regulatory resources, and user traffic—factors that also offer meaningful guidance for Robinhood choosing to build on Arbitrum.
This means that in the short term, this move doesn’t necessarily indicate $ARB is undervalued (compare with $OP’s performance). But in the long run, if Robinhood successfully executes its vision around tokenizing U.S. equities, it could transform the current尴尬 situation where Ethereum’s L2s are “technically strong but lack real-world adoption.” It could open an unprecedented path toward mass adoption for both Ethereum’s L1 and L2 ecosystems.
2) While Coinbase’s layer2 approach remains focused on general-purpose solutions—largely continuing existing use cases like DeFi, GameFi, and meme trading—Robinhood may take a different route: building a specialized layer2 tailored specifically for traditional finance (TradFi) asset tokenization and infrastructure.
Although OP-Rollups can achieve sub-second transaction finality, they still operate within the optimistic Rollup security model relying on 7-day fraud proofs. In contrast, Robinhood’s new layer2 will likely need to support stock T+0 settlement, real-time risk control, and strict compliance requirements. This may require deep customization at the layer2 virtual machine, consensus mechanism, and data structure levels—fully unlocking the potential of the layer2 scaling solution.
3) Arbitrum’s technical architecture holds certain maturity advantages over Optimism: Nitro’s WASM-based execution engine offers higher efficiency, giving it a natural edge in handling complex financial computations; Stylus enables high-performance smart contracts in multiple programming languages, suitable for heavy computational tasks common in traditional finance; BoLD mitigates malicious delay attacks, strengthening the security of optimistic verification; Orbit allows customized Layer3 deployments, offering significant flexibility for feature development.
You see, there’s good reason Arbitrum was chosen. Its technological strengths appear well-aligned with the stringent customization demands of traditional finance, going far beyond OP Stack’s “just make it work” philosophy. This makes perfect sense—when facing the ultimate challenge of supporting trillion-dollar TradFi operations, technical maturity and specialization will determine success or failure.
4) Tokenizing U.S. equities and creating crypto-native stock exchanges is no longer about the typical crypto narrative of “launching tokens and games.” The users involved aren’t just speculative traders who ignore product delivery and UX as long as price pumps. If gas volatility causes network congestion or transaction delays, users accustomed to traditional financial products would find this utterly unacceptable.
These TradFi users expect millisecond response times, 7×24 uninterrupted service, and seamless T+0 settlement. More critically, they often represent institutional capital, algorithmic trading systems, and high-frequency strategies—all of which impose extreme demands on system stability and performance. This implies Robinhood’s layer2 will serve a completely different user base, presenting an exceptionally challenging task.
That’s all.
In summary, Robinhood’s move into layer2 carries profound significance. It’s not merely about adding another player to the layer2 landscape, but rather a hardcore experiment testing whether crypto infrastructure can truly support core functions of the modern financial system.
If successful, this could accelerate the digital transformation of the entire multi-trillion-dollar TradFi market—including bonds, futures, insurance, and real estate. Long-term, it would directly benefit the real-world application of Ethereum’s L1+L2 tech stack and fundamentally redefine how value is captured within the Layer2 ecosystem.
