Robinhood describes the chain as a permissionless, Ethereum-compatible Layer 2. Chainstack records the architecture as an Arbitrum Nitro rollup with a Robinhood-operated sequencer, and dispute resolution through BoLD with a permissioned validator set. Transactions therefore inherit Ethereum finality, which arrives roughly thirteen minutes after the batch is posted to Ethereum. Soft confirmation from the sequencer is sub-second. Ordering at the sequencer is first-come, first-served by arrival time. There is no native transaction privacy: every transaction and every contract is readable through the public RPC and through Blockscout.

Add the network to a wallet

Most wallets accept an EIP-3085 request or the same values typed by hand. Verify the RPC host against Robinhood's own support article before you paste anything. A wrong RPC host is a standard phishing route.

To move funds in, Robinhood points at the canonical Arbitrum bridge at portal.arbitrum.io/bridge and at partner bridging routes. The canonical bridge is the slow, boring path and it is the one with the fewest moving parts.

Gas and block times

Average block time is about 100 milliseconds. Blockscout's own example output for the chain showed an average block time of 100 ms across more than 1.28 million blocks and more than 8.4 million transactions. Gas is paid in ETH and sits at sub-cent rates. A plain Uniswap v4 swap on the chain costs about $0.008 at the fee levels observed in August 2026.

Two cost caveats matter. First, Blockscout reported that trading actions were gas-free for users for the first ninety days after mainnet, while contract deployments and other developer transactions still paid gas. Ninety days from 2026-07-01 lands at the end of September 2026, so treat any gas-free behaviour you see as temporary and check it yourself. Second, a third-party network directory noted that Robinhood has been subsidising gas above $5 on wallet swaps. We could not confirm that figure against a Robinhood page, so we do not repeat it as fact.

Public RPC limits

The public endpoint is generous but it is shared. In our own testing the practical ceiling is about 100 requests per second per IP address, and a single client may hold one websocket connection at a time. If you are building an indexer, poll over HTTP, stay well under 50 requests per second, and treat the websocket as a convenience rather than a firehose. Anything that needs guaranteed headroom, archive depth, or trace calls belongs on a paid provider.

RPC providers

Robinhood's developer documentation names QuickNode, Alchemy, Blockdaemon, dRPC, and Validation Cloud. Goldsky, Tenderly, Chainstack, and thirdweb also publish support. Chainstack offers both mainnet 4663 and testnet 46630, on either geo-balanced shared nodes or dedicated nodes. QuickNode publishes a provider comparison of its own, which is worth reading with the usual caution about a vendor ranking itself first.

Pick a provider on three questions. Does it serve archive state, or only recent state? Does it support debug_traceTransaction, which you need for internal-transfer accounting? What is the real rate limit on the tier you will actually buy, rather than the headline number?

The Blockscout explorer and its API

Blockscout is the official explorer and has indexed the chain from block one. Three API shapes are available, all keyed to chain 4663:

Read the record cap before you design around this API. Blockscout documents that txlistinternal and eth_getLogs are limited to 1,000 records on Robinhood Chain, to keep the service responsive. You must paginate in batches of 1,000 or smaller. That cap is the reason we do not use the explorer as a primary log firehose, and neither should you.

Blockscout Pro API tiers as published on 2026-08-25.

Most endpoints consume 20 credits per call, so divide the credit figure by 20 for a realistic call budget.

Contracts worth bookmarking

These addresses were read from verified contract pages on Blockscout on 2026-08-25. Check them yourself before you send a transaction anywhere near them.

We deliberately do not publish event topic hashes for the launchpad. The correct way to get those is to pull real logs from the factory and decode them against the verified ABI on Blockscout. Topics copied out of a blog post go stale without warning.

What we could not verify. Robinhood's own support article does not state the block time, the gas cost, or the mainnet launch date, so those three come from Blockscout, Chainstack, and a third-party network directory instead. We have not found a Robinhood page that confirms the ninety-day gas-free window, and we did not find a published websocket URL for the public endpoint.
