Robinhood Chain vs Unichain

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.

Unichain is an OP‑Stack Layer‑2 built by Uniswap Labs that employs a trusted‑execution‑environment (TEE) block builder to guarantee ordered execution free from MEV. Liquidity pools enjoy baked‑in sandwich protection, and the UNI token governs sequencer whitelists. The chain inherited native hooks from upcoming Uniswap V4, enabling dynamic fee models.
