Robinhood Chain vs Sonic

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.

Sonic is an ultra‑fast EVM Layer‑1 claimed to reach 400k TPS and sub‑second finality via a custom SonicVM and DAG‑based consensus dubbed Tempo. Blocks are final once two‑thirds of stake attest, and state is stored in an in‑memory ledger that snapshots to disk every epoch. The project focuses on GameFi and real‑time social dApps, with an incentive testnet launched in May 2025.
