Robinhood Chain vs Sei

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.

Sei is a parallelised Cosmos‑SDK Layer‑1 optimized for order‑book exchanges, using Twin‑Turbo consensus to reach 300–400 ms finality. Its built‑in matching engine lets dApps compose on a shared liquidity layer, and fee markets are denominated in SEI with bulk‑order discounts. The ‘V2’ upgrade adds EVM compatibility via SeiDB and WASM contracts side‑by‑side.
