Robinhood Chain (chain 4663) is Robinhood’s own L2, where tokenized stocks and memecoins trade onchain. Most routing engines don’t cover it — Protos does, natively, through Definitive’s Flash for execution and Relay for bridging. Everything on this page is non-custodial: Protos quotes, your wallet signs every step, and Protos never touches your funds.

​
Native swaps

Same-chain swaps on Robinhood Chain, quoted live through Flash:
  • USDG (Paxos’s Global Dollar) is the chain’s real stablecoin — there is no meaningful USDC liquidity here. Type USDC anyway and Protos silently resolves it to USDG.
  • Spending native ETH adds an automatic wrap step (the chain’s pricing engine trades WETH) — Protos builds the wrap transaction for you, you just sign it.
  • Orders are EIP-712 typed data signed in your own wallet; submission happens server-side, but nothing executes without your signature.

​
Buy tokenized stocks

25 stock and ETF tokens — NVDA, TSLA, AAPL, MSFT, GOOGL, AMZN, META, COIN, SPY, QQQ, and more:
Ticker resolution goes through Robinhood’s own contract registry first, never a DEX search. This matters: the chain has heavy ticker-impersonation activity (copycat “AAPL”/“TSLA” tokens with real liquidity of their own), and a symbol search can’t tell the real Robinhood-issued token from a fake. The registry can.

​
Advanced orders

Limit, stop-loss, take-profit, and TWAP — in plain English, on Robinhood Chain plus 7 EVM chains (Base, Arbitrum, Ethereum, Optimism, Polygon, BSC, Avalanche):
Add on base / on arbitrum to place the order there — USDC settles off Robinhood Chain, USDG on it. Natural phrasings the strict patterns miss go through a schema-validated LLM parse that can never invent a number you didn’t type — a missing price or amount gets asked for, not guessed. Trigger-order previews show both numbers honestly: what the trigger price implies you’d receive (“est. received at trigger ≈ …, after fees”) and what the same sell would fetch at current price — clearly labeled so a market quote is never mistaken for trigger proceeds.

​
Managing orders

Standing orders render as a card with status, fill progress, and trigger price — anything still cancellable gets a cancel button (you sign the cancellation, like everything else).

​
Bridge in and out

Cross-chain routes into chain 4663 aren’t covered by the usual aggregators — Protos bridges through Relay:
Both directions live-confirmed. This is how funds get onto the chain before trading.

​
Launch feed

Roughly one token launches on this chain every 1–2 minutes. Protos surfaces the feed with real safety signals attached, not just a raw list:
Returns the 5 most active recent launches ranked by volume-to-market-cap ratio (above 10x gets a 🔥), each with a live risk badge (the same DexScreener liquidity/honeypot scan behind Token Safety), color-coded liquidity, a repeat-launch warning linking to the deployer’s full launch history on NOXA, a copyable contract address, and links to Bankr, DexScreener, and GeckoTerminal.
There’s no “past day / past week” filter on purpose — the most-recent batch only ever spans about 30 minutes at current launch pace, so a longer window would silently show the same 30 minutes every time. Protos shows exactly how much time the batch spans instead.
A token that’s 1–2 minutes old can show “not indexed yet” — that’s DexScreener’s indexing lag, not a chain-support gap; Protos says so instead of faking a risk score. And token names on a permissionless chain are unverified — anyone can launch a token riffing on a real person or brand with zero affiliation. Treat the name as decoration; the risk scan and deployer history are the real signals.

​
Stock-paired token intel

A Robinhood Chain original: tokens whose liquidity pool quotes against a tokenized stock instead of USDG or WETH — $REAL trades against NVDA, so every trade accrues fees in NVDA to the creator. Protos detects the category from pool data and reads it:
The card shows the pairing (with a registry-verified badge when the quote token matches Robinhood’s official contract — an impersonator NVDA pool fails it), the token/stock ratio, the live stock price via Pyth, and the fee flywheel: estimated daily and since-launch creator fees, in USD and stock-token terms.
Fee figures are estimates from trading volume, based on standard Doppler launch parameters (0.7% pool fee, 95% creator share) — not exact unclaimed balances. Individual tokens can configure different tiers.
Research commands (deep dive on 0x…, is X safe, research X) automatically attach the stock-pairing context when the token qualifies.

​
$PROTOS on Robinhood Chain

$PROTOS itself trades here — NVDA-paired, so it’s a stock-paired token by its own definition:
The address is pinned server-side, so PROTOS always resolves to the real token, never a same-ticker copycat. (This is a separate token from the $protos on Base used for Smart-tier holder limits.)

​
Portfolio & transactions

Balance and transaction-hash lookups work on Robinhood Chain too (via Blockscout — one of 9 chains Protos covers that the mainstream indexers don’t):

For agents

Everything conversational above has a machine counterpart. POST /api/flash-order on the agent-payable x402 API prices any advanced order (limit / stop-loss / take-profit / TWAP) for $0.02 per call — structured JSON in, priced route + sign-in link out, USDC on Base, no API key or signup. Agents get a link, never raw calldata — the non-custodial contract holds for machines too.
