How the desk works
This version
The market is named OpenSpace ($OPSI). Swaps quote official Uniswap v2, v3, and v4 pools, including a custom fee and a hop through USDG or WETH, and take the route that returns more. Perps open as a trade screen: a Lighter candle chart, market list, order book, live prints, open positions, and a ticket with leverage, order value, and margin. Click a book level to fill the size. Deposit and withdraw sit on that ticket. The trading key stays on the Lighter account: clearing browser data deletes only the copy in this browser, and the same wallet unlocks it. The agent answers questions about the desk and still only prepares a swap. Your wallet is the only signer.
What this is
OpenSpace is an on-chain market for swapping tokens, providing liquidity, and trading perps across Solana and Robinhood Chain. It is not the Robinhood brokerage, it does not take custody, and it does not place stock orders. A swap is an on-chain transaction that your wallet signs. A perp is an order signed by your wallet or trading key.
Which tokens
The stock and ETF list is the live Robinhood asset registry, the same set published for Robinhood Stock Tokens. WETH and USDG are the settlement rails. Coins are the extra vetted addresses from the public Robinhood Chain token list that are not already in that registry. A matching ticker with a different contract is not a Robinhood stock token.
Any token to any token
Choose what you pay and what you receive. There is no requirement to trade against USDG. The quote checks every official Uniswap v2, v3, and v4 pool it can find for the pair, including pools with a custom fee, direct and through USDG or WETH, and uses whichever returns more. The ticket shows the venue and the fee. If no pool has liquidity, the swap stays disabled. A route stays on one venue: a v3 hop and a v4 hop are not combined in one transaction.
Chart versus pool
The chart is the underlying share session. Bid, ask, high, low, and volume come from Robinhood’s stock-token price feed when the symbol is listed. Chain coins do not have a share chart. The price on the swap ticket is the pool output after the route is chosen. Do not treat one as the other.
What your wallet signs
If you pay WETH and only hold ETH, the shortfall is wrapped first. The token is approved to Permit2 if the allowance is short. Permit2 is approved for the Universal Router if that allowance is short or about to expire. The swap is simulated, then sent to the router with a 0.50% minimum and a ten-minute deadline. You can reject any of those prompts.
Mainnet
OpenSpace trades Robinhood Chain mainnet (chain 46630) and Solana mainnet. USDG is the settlement token on Robinhood Chain and uses 6 decimals. Stock tokens use 18. There is no testnet on this site.
The agent
Open the Agent tab and ask how the desk works: pools, fees, deposits, withdrawals, the trading key, eligibility, or a share-session price. You can also paste a contract, then say buy it with ETH for any dollar amount, or sell it to ETH, USDG, or another token. Five dollars was only an example. A contract sent on its own is remembered for the next sentence. The agent quotes Uniswap and shows what you pay and the minimum you receive. Approve in wallet is the only way a transaction is created. It cannot sign, move funds, or give financial advice. Rejecting a wallet prompt cancels the swap.
Perpetuals
The Perps tab reads Lighter’s public market on Robinhood Chain, not Lighter’s other exchange. The chart is that market’s mark candles, not the stock-token share chart on Swap. Open positions, entry, unrealized PnL, and liquidation come from the Lighter account after you connect. Deposit USDG from the page. The minimum is 1 USDG, and the first deposit opens the account. Withdraw sends free USDG margin back to the same wallet after Lighter’s next batch, usually a few minutes, not in the same moment. Open positions keep the margin they need. The trading key signs the withdrawal and the orders, so you never paste a private key. The first time, the wallet signs twice: once to define the key, once to register it on Lighter. This browser keeps a copy so later trades do not ask the wallet. Clearing browsing data deletes only that copy. Unlock trading key with the same wallet brings the same key back. After the key is ready, buy and sell are market orders with cross leverage up to that market’s maximum. The worst price is 1% from the touch, and the rest is cancelled. A click on the book only fills the size. Swap remains the Uniswap trade your wallet signs.
Solana Swap & xStocks
When Solana is selected in the top bar, Swap routes through Jupiter across Solana DEX pools. You can trade Solana majors (SOL, USDC, USDT, JUP, BONK, WIF, RAY, JTO, PYTH), tokenized equities (xStocks such as TSLAx, NVDAx, AAPLx, MSTRx, SPYx, QQQx), live DexScreener trending tokens, or any custom SPL mint address pasted into the ticket. You can flip any token into the pay slot, choose your slippage tolerance (0.5%, 1.0%, or 2.0%), inspect minimum received and price impact, and sign directly in Phantom.
Solana Perps (Jupiter JLP & Drift Protocol v2)
On Solana, the Perps tab connects to Jupiter Perpetuals backed by the JLP liquidity pool for SOL, ETH, and BTC with up to 100x leverage, and to Drift Protocol v2 on-chain DLOB for 21 additional perpetual markets (DOGE, XRP, BNB, SUI, AVAX, LINK, LTC, ADA, HYPE, TAO, WIF, JUP, INJ, SEI, PYTH, RENDER, ARB, OP, TIA, APT, and POPCAT) up to 20x leverage. Phantom signs the transaction directly.
Cross-Chain Bridge (deBridge DLN)
The Bridge tab quotes and builds intent-based cross-chain transfers across Solana, Base, Arbitrum, Polygon, and Ethereum via deBridge DLN solvers. Move USDC, SOL, ETH, or POL in seconds to fund Solana Perps, Base Limitless markets, or Polygon Polymarket orders. Phantom signs when bridging from Solana; your EVM wallet signs when bridging from Base, Arbitrum, Polygon, or Ethereum.
Book (Solana · Base · Polygon)
The Book tab streams live prediction markets across three chains: Solana (Jupiter Prediction routing Polymarket events settled in Solana USDC via Phantom), Base (Limitless Exchange daily stock and crypto markets settled in Base USDC on Chain 8453), and Polygon (Polymarket CLOB settled in pUSD on Chain 137).
Eligibility
Robinhood Stock Tokens and tokenized equities (xStocks) are not offered or sold to U.S. persons. Holding one is economic exposure through a token, not ownership of the underlying share. Confirm you are allowed to trade the canonical contracts before you sign on mainnet.
