Lighter [RH]
Lighter's deployment on Robinhood Chain — the same exchange engine and API as Lighter, running as a separate venue with its own accounts, collateral and markets.
| Property | Value |
|---|---|
| Runs on | Lighter's Robinhood Chain deployment (robinhoodchain.lighter.xyz) |
| Markets | Crypto perps plus 24/7 tokenized equity, ETF and commodity perps (AAPL, NVDA, SPY, XAU, …) |
| Collateral | USDG on Robinhood Chain (not USDC) |
| Transport | WebSocket (order placement + market data) |
| Signing | Schnorr, same scheme as Lighter — separate key registered on this deployment |
| Funding interval | 1 hour |
| Concurrent Spreadr maker trades | up to 3 per wallet — one API key slot each, as on Lighter |
| Builder code support | ✅ — 0.5 bp via Spreadr's own integrator account on this deployment |
Separate account from Lighter. Your Lighter (mainnet) account, API keys, volume quota and rate limits do not carry over. You need an account funded with USDG on Robinhood Chain, and you connect it in Spreadr as its own venue. The account must be Premium, exactly as on Lighter: Standard and Plus accounts are refused when you connect and when a trade starts.
Account setup
Open and fund an account
Visit robinhoodchain.lighter.xyz (opens in a new tab), connect your L1 wallet, and deposit USDG (Robinhood Chain). Perps and tokenized-stock trading through this deployment follows Lighter's own eligibility rules; the Robinhood Wallet app additionally excludes residents of the US, UK, Canada, Switzerland, the UAE and Singapore — check your own eligibility before funding.
Connect in Spreadr
In the terminal: Settings → Wallets, pick your wallet, then + Lighter [RH] → Connect Lighter [RH]. Spreadr discovers your account index on this deployment, generates the signing keypair in your browser, and registers it. You sign the key authorization, a one-time fee authorization (only if the account hasn't given it before), and the credential vault unlock. Spreadr then checks the account is Premium and stops if it isn't.
Quirks
- Everything account-side is separate. Collateral (USDG), quota, rate limits and the one-maker-trade cap are all per deployment. A wallet connected to Lighter is not connected to Lighter [RH].
- Same symbol, two venues. Spreading a market against itself across the two deployments (e.g. BTC on Lighter vs Lighter [RH]) works. Each deployment has its own volume quota, so when the maker side's quota is low Spreadr moves the maker to the other deployment if that one's quota is healthy; if both are low, the trade still runs, with a warning.
- Equities trade 24/7 here. Tokenized-stock perps quote around the clock; funding and spread behavior can differ from the underlying's market hours.
- Portfolio history is per deployment. The Performance charts read this account's own funding export and PnL curve, separately from Lighter (mainnet).
- Lighter's other quirks apply unchanged: dedicated sub-account, one maker trade per API key slot, no second bot on the same key, volume quota. See Lighter.
Common errors
| Symptom | Cause | Fix |
|---|---|---|
| "No Lighter [RH] account found for this wallet" | The wallet has no account on the Robinhood Chain deployment | Deposit USDG on robinhoodchain.lighter.xyz first, then reconnect |
| The account "is on the standard tier" (or plus) | This deployment's account isn't Premium | Switch it to Premium on robinhoodchain.lighter.xyz, then connect again or restart the trade |
| "Insufficient collateral" | USDG margin too thin | Deposit USDG or reduce leverage |
| "Invalid nonce" | Another process is signing with the same API key | Make sure only Spreadr uses this key |
