Summary

  • Robinhood launched the public mainnet for its AI-native Ethereum Layer 2 built on Arbitrum infrastructure in early July 2026.
  • The chain delivers 100ms block times and full Ethereum security, targeting onchain finance applications.
  • Ethereum L1 gas limit increases and ongoing L2 growth support broader scaling efforts as ETH holds bullish momentum.

Robinhood launched its Arbitrum-powered Ethereum layer-2 on the public mainnet. This happened on Wednesday in early July 2026. The move ties into scaling talks at TechCrunch Disrupt 2026 and climbing ETH prices.

Robinhood Chain gives public access to an AI-native network built for onchain finance.

This pushes Ethereum L2 scaling forward. It extends Arbitrum's infrastructure to a big brokerage platform. Users get high-throughput trades backed by Ethereum security.

They also tap into Robinhood's large user base.

Context

Ethereum grew its base layer capacity over recent years. The L1 gas limit jumped from 30M to 60M in 2025. Further boosts should hit in the second half of 2026.

These upgrades free up space for Layer 2 solutions.

Robinhood Chain uses this base. It runs on Arbitrum for tokenization and finance apps. ETH stays bullish in July 2026, which fits the timing.

"Ethereum has had the most credibly neutral, liquid, and battle-tested base layer in crypto. So we're scaling it, independently."

Details

Robinhood Chain uses Arbitrum's Layer 2 setup. It hits 100ms block times and keeps Ethereum security. Reports confirm the public mainnet went live in early July 2026.

The focus stays on onchain finance like tokenized stocks.

Arbitrum provides the finance-native platform. It backs apps and tokenization that align with Robinhood's plans.

The AI-native design boosts performance for financial tasks.

L2 growth still needs Ethereum upgrades and clear rules. No user numbers or token info came out yet.

Ethereum's 2025 gas limit changes add room. This helps more L2 networks grow.

Outlook: Developers and users can now interact directly with the live Robinhood Chain mainnet, with further Ethereum upgrades expected later in 2026 to expand overall capacity.
