# Robinhood Chain

> Chain ID 4663: Robinhood's Ethereum L2 for tokenized real-world assets — Stock Tokens, their oracles and multipliers, the protocol contracts, and the Doppler launch protocol.
> Covers: Robinhood Chain (chain ID 4663) as documented on 2026-09-09: connecting and network config, gas, transaction finality, differences from Ethereum, Stock Tokens and their legal structure as tokenised debt securities issued by Robinhood Assets (Jersey) Limited, building against them, the stock-token APIs, Chainlink price feeds and the Total Return Value formula, UI multipliers and corporate-action handling, protocol and token contracts, deploying, account abstraction, bridging, cross-chain messaging, data streams, running a node, governance, the Uniswap v4 deployment on 4663, and the Doppler launch protocol. Also documents where the official docs contradict each other or their own Terms of Service.
> Not covered: Per-ticker Stock Token contract addresses and Chainlink feed proxy addresses — both tables render client-side and are deliberately NOT reproduced here; resolve them from the live sources. Any claim about how many tickers have feeds. Whether an on-chain role registry, blocklist or proxy-admin power exists beyond what the docs disclose. The chain's launch date and upgrade history, which no source states. Doppler behavior not explicitly scoped to 4663 — its docs are multi-chain and its SDK examples target Base. Prices, market data, token valuations, and anything resembling trading or investment advice.
