# Robinhood Chain

> The network Stockline runs on.

Stockline runs on Robinhood Chain, an Arbitrum Orbit L2.

Testnet chain ID is 46630. Mainnet chain ID in these docs is 4663. Confirm against [Addresses](/resources/addresses) before you send a transaction.

The app copy footer says Robinhood Chain · id 46630 · all values read from the contracts at the block shown.

There is no published Chainlink sequencer uptime feed for this chain yet. `EquityOracle` accepts `sequencerFeed = address(0)` and never trips `SEQ_DOWN` in that config. ARCHITECTURE.md lists sequencer as an input. The code makes it optional.

ETH for gas on testnet comes from faucet.testnet.chain.robinhood.com. The Stockline faucet does not mint the native token.

Stock tokens, USDG, and STK are ERC-20s on this chain. The core never sees USDC. `Zap` converts allowlisted assets using registry routes.

<Note>
  This section will be completed when Robinhood publishes canonical mainnet RPC, explorer, and sequencer-feed addresses. Until then, use the testnet table on Addresses.

Fork tests in the contracts repo use RPC\_URL against this chain. Weekend, Halt, Split, SequencerDown, and GapLiquidation are the named scenarios. If you are writing a keeper, those tests are the spec for what your bot must survive.

Explorers and RPC URLs in Addresses are the canonical links for this docs build. If Robinhood publishes different hosts, this page will change on the next generate of Addresses.

Gas is sponsored in the Stockline app. Third-party apps must plan for native ETH. The testnet faucet page points at the chain faucet for that.
