Robinhood Chain vs dYdX

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.

The dYdX Chain is an app‑specific Cosmos chain that replaced the prior StarkEx L2, giving validators control over an on‑chain order book for perpetual futures. Traders retain familiar features like cross‑margin and isolated positions, and DYDX token holders secure the chain while receiving 100 % of protocol fees. Lambda architecture shards order processing across ABCI++ extensions for sub‑second latency.
