Robinhood Chain vs Starknet

Robinhood Chain is Robinhood's permissionless Ethereum Layer‑2 built on Arbitrum's Orbit stack, with a public testnet from February 2026 and mainnet launch on July 1, 2026. It offers full EVM compatibility, 100‑millisecond blocks, ETH as the native gas token, and native ERC‑4337 account abstraction for gas sponsorship and social recovery, with BitGo and Alchemy providing custody and node infrastructure. The chain is purpose‑built for tokenized real‑world assets, hosting 24/7 Stock Tokens that track US equity prices (without ownership or voting rights) alongside DeFi venues such as Uniswap, Lighter and Morpho‑powered lending; no dedicated Robinhood Chain token is mapped, so the blockchain is imported without an associated token.

Starknet is a STARK‑based validity rollup where smart contracts are written in Cairo and executed off‑chain, with succinct proofs verified on Ethereum. The 2024 Madara sequencer supports parallel execution, and the ‘Quantum Leap’ upgrade reduced L1 calldata by 30 %. STRK token launched in February 2025, enabling slot auctions for sequencer decentralization roadmap.
