Robinhood Chain vs Solana

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.

Solana combines Proof‑of‑History, Turbine block propagation and Gulf Stream forwarding to achieve throughput exceeding 50 000 TPS with 400 ms block times. The 2024 Firedancer client written in C++ reduced validator CPU requirements and added parallel pipeline execution. Solana Pay and the Saga phone SDK illustrate the project’s push toward consumer‑grade web3 applications.
