Robinhood Chain vs Sui

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.

Sui employs an object‑based data model and Narwhal/Tusk DAG consensus to execute independent transactions in parallel, giving near‑instant finality. Programmability uses the Move‑based Sui language with object ownership, enabling upgrades without storage migrations. The network supports sponsored transactions, letting dApps pay gas on behalf of users—a boon for mobile onboarding.
