Straight answers about Robinhood Chain

What is the Robinhood Chain RPC URL?

The public mainnet RPC endpoint is https://rpc.mainnet.chain.robinhood.com and the testnet endpoint is https://rpc.testnet.chain.robinhood.com. Both are free, unauthenticated, and rate-limited — Robinhood's own documentation says they are unsuitable for production.

What is the Robinhood Chain chain ID?

Robinhood Chain mainnet is chain ID 4663 (0x1237). The testnet is 46630. Both use ETH as the gas token.

What is Robinhood Chain?

Robinhood Chain is a permissionless Ethereum Layer 2 built on Arbitrum Nitro, launched to mainnet on 1 July 2026. Its distinguishing feature is native tokenized equities — over 200 US stocks and ETFs that trade onchain around the clock.

How do I use the Robinhood Chain testnet?

The Robinhood Chain testnet is chain ID 46630, with RPC at https://rpc.testnet.chain.robinhood.com and a block explorer at explorer.testnet.chain.robinhood.com. It uses ETH for gas, like mainnet.

How do I add Robinhood Chain to MetaMask?

Add a custom network with RPC URL https://rpc.mainnet.chain.robinhood.com, chain ID 4663, currency symbol ETH, and block explorer https://robinhoodchain.blockscout.com. Robinhood Chain is EVM-equivalent, so no other configuration is needed.

What is the Robinhood Chain block explorer?

The official explorer is Blockscout at https://robinhoodchain.blockscout.com. A third-party explorer, Robinscan, is available at https://robinscan.io, and the testnet explorer is at explorer.testnet.chain.robinhood.com.

What token does Robinhood Chain use for gas?

Robinhood Chain uses ETH for gas on both mainnet and testnet. There is no separate native token.

How is Robinhood Chain different from Arbitrum?

Robinhood Chain is built with Arbitrum's Nitro stack as an Orbit chain, so it shares Arbitrum's execution semantics, transaction types and tracing model. The difference is purpose: it hosts native tokenized US equities, which Arbitrum One does not.

What are Robinhood stock tokens?

Robinhood stock tokens are ERC-20 tokens on Robinhood Chain representing tokenized US equities and ETFs — over 200 instruments including AAPL, NVDA and TSLA. They use 18 decimals and extend ERC-20 with ERC-8056, the Scaled UI Amount Extension.

Why is my Robinhood stock token balance unchanged after a split?

Because Robinhood stock tokens express corporate actions through a multiplier, not by minting tokens. Your raw balanceOf() stays identical across a 4-for-1 split; the uiMultiplier() quadruples instead. Your position has changed even though the number in your wallet has not.

What is uiMultiplier() and ERC-8056?

ERC-8056 is the Scaled UI Amount Extension. It adds uiMultiplier() to an ERC-20, a scaling factor with 18 decimals where 1e18 equals 1.0, letting a token change what a balance represents without changing the balance itself.

How do dividends work on Robinhood stock tokens?

Dividends are reinvested into the token by increasing uiMultiplier(), not paid out as cash. Your raw balance is unchanged; each token simply represents slightly more of the underlying share afterwards.

What happens to a Robinhood stock token in a split?

A split multiplies uiMultiplier() by the split ratio and leaves raw balances alone. Because a split is a price discontinuity, the contract requires a scheduled pause window and manual confirmation before trading resumes.

Is there a corporate actions API for Robinhood Chain?

Yes. Robinhood publishes GET https://api.robinhood.com/rhj/corporate-actions free and unauthenticated, rate-limited to 60 requests per second with a one-hour cache. It covers 13 action types.

How do I get Robinhood stock token prices?

There are four different prices for every stock token and they disagree by construction. Robinhood's REST endpoint returns the raw underlying equity price; Chainlink's onchain feed returns the multiplier-adjusted token price. Mixing them without care is a silent, expensive bug.

What is the premium or discount on a tokenized equity?

The premium is the gap between what a stock token trades at onchain and what its underlying equity is worth, expressed in basis points. It is the defining signal on a tokenized-equity chain, and no provider on Robinhood Chain publishes it.

What is the Robinhood Chain sequencer feed?

The sequencer feed at wss://feed.mainnet.chain.robinhood.com is a free, public WebSocket that pushes transactions the instant they are sequenced — before block inclusion. It is the lowest-latency signal available on the chain.

Is there a gRPC API for Robinhood Chain?

No provider on Robinhood Chain currently offers gRPC. Alchemy, the provider Robinhood recommends, explicitly lists gRPC as unsupported on this chain in its own documentation.

Which Robinhood Chain providers support trace and debug?

Alchemy — the provider named in Robinhood's own documentation — does not support the trace namespace or the full debug namespace on Robinhood Chain, per Alchemy's own docs. QuickNode, Chainstack, dRPC, GetBlock and Dwellir do.

How do I get archive access to Robinhood Chain?

Several providers offer archive access, including QuickNode, GetBlock, Dwellir, dRPC and Chainstack. You can also run your own — Robinhood publishes the node image, offchainlabs/nitro-node:v3.11.2-3599aca.

Does Robinhood Chain support WebSocket subscriptions?

Yes. Robinhood Chain supports standard eth_subscribe over WebSocket for newHeads, logs, newPendingTransactions and syncing. Most commercial providers expose a wss:// endpoint alongside their HTTPS one.

Can I run a subgraph on Robinhood Chain?

Yes, through Goldsky or Ormi, both of which are Graph-protocol compatible. The Graph itself has no confirmed Robinhood Chain support, which is an unusual gap for a chain this prominent.

Which is the best Robinhood Chain RPC provider?

It depends on what you need, and the officially recommended option is not the most capable. Alchemy is named in Robinhood's documentation but lacks trace, debug, simulation and gRPC on this chain; QuickNode, Chainstack, Dwellir and GetBlock all offer a wider method surface.

Is there a free Robinhood Chain RPC endpoint?

Yes, two. Robinhood runs a public endpoint at https://rpc.mainnet.chain.robinhood.com, and PublicNode offers a free keyless one at https://robinhood-rpc.publicnode.com with MEV protection. Several commercial providers also have free tiers.
