Safety Rules

• Never ask for private keys, seed phrases, API private keys, passwords, or wallet credentials.
• Never log, echo, store, or display secrets. The only credential an agent should use is SUPERIOR_TRADE_API_KEY.
• Never move funds or start live trading without explicit user confirmation.
• Never submit a Lighter order or sendTx proxy payload without explicit user confirmation of market, side, size, order type, and risk.
• Treat Lighter deposits and withdrawals as real fund-moving actions.
• Treat signed sendTx payloads as real trading actions. The proxy forwards the signed transaction; it does not simulate or validate the trading intent.
• Do not retry an ambiguous withdrawal automatically. Poll the withdrawal status endpoint and report the persisted state.
• Use the user's Superior-managed owner wallet as owner_address. An external deposit wallet is only the payer; it does not become the Lighter owner.
• Do not claim Lighter readiness or balance without querying the API.

Account Model

Lighter does not reuse the Hyperliquid funding flow.

Deposit:
External wallet -> native USDC transfer to Lighter CCTP intent -> Lighter

Ownership and signing:
Superior-managed Privy wallet -> Lighter L1 owner -> Lighter API key index 4

Withdrawal:
Lighter -> fast withdrawal -> external EVM wallet

The Lighter account index is created only after the first credited deposit. Readiness can move through:

needs_deposit -> deposit_pending -> account_created
              -> api_key_approving -> ready
                                    -> key_provisioning_unknown

Proceed with live deployment only when the account status is ready.

Account Onboarding

POST /v3/account/{address}/lighter

Onboard or repair a Lighter account for an owned Superior-managed wallet. After the first credited deposit, this endpoint records the Lighter account index and approves Superior-managed Lighter API key index 4 when needed.

curl -sS -X POST "https://api.superior.trade/v3/account/${OWNER_ADDRESS}/lighter" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}" \
  -H "content-type: application/json"

Use this after the first deposit is credited, or when status shows account_ready: true and api_key_ready: false.

Response fields:

• account_ready: Lighter account exists and collateral can be read.
• api_key_ready: Superior-managed Lighter API key is approved and stored.
• ready: both account_ready and api_key_ready.
• api_key_approval_tx_hash: Lighter transaction hash for approving API key index 4.

If the response status is api_key_approving, poll GET /v3/account/{address}/status/lighter until ready: true or manual review is required.

GET /v3/account/{address}/status/lighter

Check account and API-key readiness before deposits, signed proxy submissions, withdrawals, or live deployment.

curl -sS "https://api.superior.trade/v3/account/${OWNER_ADDRESS}/status/lighter" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}"

Expected statuses include needs_deposit, deposit_pending, account_created, api_key_approving, key_provisioning_unknown, and ready.

If the status is key_provisioning_unknown, stop and report that manual review is required. Do not rotate keys or retry blindly.

If account_ready: true and api_key_ready: false, call POST /v3/account/{address}/lighter only after the user confirms they want to onboard the account for trading/API-key use.

Balance

GET /v3/portfolio/lighter/balance

curl -sS "https://api.superior.trade/v3/portfolio/lighter/balance?owner_address=${OWNER_ADDRESS}" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}"

Returns the Lighter account balance associated with owner_address. Before the first credited deposit, the API can return zero balance with needs_deposit.

Immediate Market Order

POST /v3/authorize-and-send/lighter

Use placeOrder when the user asks for one immediate Lighter market order, such as "buy $10 ETH". The Superior API resolves the user's owned wallet, loads the stored Lighter API key, signs the Lighter order server-side, and submits it to Lighter. Agents only send SUPERIOR_TRADE_API_KEY; never ask for or handle Lighter API private keys.

Before calling this endpoint, verify:

1. GET /v3/account/{address}/status/lighter reports ready.
2. GET /v3/portfolio/lighter/balance?owner_address=... shows enough collateral.
3. The market minimum quote/base amount can support the requested size.
4. The user explicitly confirms the live order.

Show this confirmation before submitting:

Lighter Order Summary:
* Market: [symbol / market_id]
* Side: [buy | sell]
* Quote amount: [amount] USDC
* Max slippage: [fraction, e.g. 0.005 = 0.5%]
* Owner wallet: [owner_address]

This will place a REAL market order on Lighter. Proceed? (yes/no)

Request:

curl -sS -X POST "https://api.superior.trade/v3/authorize-and-send/lighter" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}" \
  -H "content-type: application/json" \
  -d '{
    "action": {
      "type": "placeOrder",
      "from": "0xSuperiorManagedWallet",
      "market_id": 0,
      "side": "buy",
      "quote_amount": "10",
      "max_slippage": "0.005",
      "reduce_only": false,
      "price_protection": true
    }
  }'

Notes:

• market_id: 0 is ETH perp on Lighter mainnet. Query market metadata before using other ids.
• quote_amount is USDC notional, not base size.
• If Lighter returns a minimum-size or slippage error, do not retry blindly. Re-check market metadata and ask the user to confirm the adjusted order.
• The legacy sendTx action remains available only for already-signed Lighter payloads.

Direct CCTP Deposit

POST /v3/portfolio/lighter/deposit

Creates a Lighter intent address for an external wallet to fund directly with native USDC. Funds do not pass through a Superior balance.

Supported source chains: arbitrum, base, avalanche. Minimum amount: 5 USDC. Required header: Idempotency-Key with a stable unique value for this deposit attempt.

Before calling this endpoint, show the user:

Lighter Deposit Summary:
* Source chain: [arbitrum | base | avalanche]
* Asset: native USDC
* Amount: [amount] USDC
* Payer wallet: [source_address or user's external wallet]
* Lighter owner: [owner_address]
* Destination: Lighter CCTP intent address returned by the API

This will move REAL USDC from the payer wallet to Lighter. Proceed? (yes/no)

Request:

curl -sS -X POST "https://api.superior.trade/v3/portfolio/lighter/deposit" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}" \
  -H "content-type: application/json" \
  -H "Idempotency-Key: ${IDEMPOTENCY_KEY}" \
  -d '{
    "owner_address": "0xSuperiorManagedWallet",
    "source_address": "0xOptionalExternalPayer",
    "source_chain": "arbitrum",
    "amount": "5"
  }'

The response includes the chain, native USDC contract, transfer destination, beneficiary owner, and operation id. The user or browser wallet signs the USDC transfer; the API never exports the Superior-managed key for deposits.

GET /v3/portfolio/lighter/deposit/{depositId}

Poll deposit status and reconcile the persisted operation.

curl -sS "https://api.superior.trade/v3/portfolio/lighter/deposit/${DEPOSIT_ID}?owner_address=${OWNER_ADDRESS}" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}"

Reconciliation is read-only and never submits funds.

Fast Withdrawal

POST /v3/portfolio/lighter/withdraw

Withdraws Lighter USDC to an external EVM wallet. The API signs with the Superior-managed owner and its encrypted Lighter API key.

Minimum amount: 4 USDC. Required header: Idempotency-Key with a stable unique value for this withdrawal attempt.

Before calling this endpoint, show the user:

Lighter Withdrawal Summary:
* Asset: USDC
* Amount: [amount] USDC
* Lighter owner: [owner_address]
* Destination: [to_address]

This will move REAL USDC out of Lighter. Ambiguous submissions are recorded as unknown and must be reconciled by polling status. Proceed? (yes/no)

Request:

curl -sS -X POST "https://api.superior.trade/v3/portfolio/lighter/withdraw" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}" \
  -H "content-type: application/json" \
  -H "Idempotency-Key: ${IDEMPOTENCY_KEY}" \
  -d '{
    "owner_address": "0xSuperiorManagedWallet",
    "to_address": "0xExternalDestination",
    "amount": "4"
  }'

The API returns 202 when the withdrawal is submitted, replayed, or recorded as unknown for reconciliation. If the response or status is unknown, do not resubmit with a new idempotency key. Poll the withdrawal id.

GET /v3/portfolio/lighter/withdraw/{withdrawalId}

curl -sS "https://api.superior.trade/v3/portfolio/lighter/withdraw/${WITHDRAWAL_ID}?owner_address=${OWNER_ADDRESS}" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}"

Use this to reconcile withdrawal state. Reconciliation never resubmits a withdrawal.

Signed Transaction Proxy

POST /v3/authorize-and-send/lighter

Submits one pre-signed Lighter transaction payload through Superior Trade's Lighter proxy. This is the next step for placing an order when another component has already produced a signed Lighter tx_type and tx_info.

The proxy:

• verifies the optional from wallet is owned by the authenticated user;
• accepts only action.type: "sendTx";
• forwards tx_type, tx_info, and price_protection to Lighter /api/v1/sendTx;
• does not build, sign, decode, simulate, or explain the order payload.

Before submitting an order payload, show the user:

Lighter Order Proxy Summary:
* Owner wallet: [from or default Superior-managed wallet]
* Market: [market/instrument from the order builder]
* Side: [buy/sell or long/short]
* Size: [quantity/notional]
* Order type: [market/limit/etc.]
* Price / limit: [price or N/A]
* Price protection: [true/false]

This will submit a REAL signed Lighter transaction. Proceed? (yes/no)

Request:

curl -sS -X POST "https://api.superior.trade/v3/authorize-and-send/lighter" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}" \
  -H "content-type: application/json" \
  -d '{
    "action": {
      "type": "sendTx",
      "from": "0xOptionalSuperiorManagedWallet",
      "tx_type": 14,
      "tx_info": "{\"AccountIndex\":123,\"MarketIndex\":0}",
      "price_protection": true
    }
  }'

Rules:

• Do not invent tx_type or tx_info. They must come from a trusted Lighter order builder/signer.
• Keep price_protection enabled unless the user explicitly asks to disable it and understands the risk.
• If the proxy returns lighter_error, do not resubmit blindly. Report the error and inspect whether the signed payload, market, price, or account readiness is invalid.
• Before placing an order, GET /v3/account/{address}/status/lighter should report ready: true.

Nautilus Deployment

Lighter strategy deployment uses the v3 Nautilus deployment API. It is separate from Hyperliquid Freqtrade deployments.

Create a Lighter deployment

curl -sS -X POST "https://api.superior.trade/v3/deployments" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}" \
  -H "content-type: application/json" \
  -d '{
    "region": "tokyo",
    "deployment": {
      "code": "class LighterStrategy: pass\n",
      "config": {
        "venue": "lighter",
        "instrument_id": "BTC-PERP.LIGHTER"
      }
    }
  }'

Rules:

• config.venue must be exactly lighter.
• config.instrument_id must be formatted as <symbol>.LIGHTER, for example BTC-PERP.LIGHTER.
• The API plans the lighter-tokyo venue profile.
• Lighter live deployments require a ready Lighter account and stored credentials.

Store deployment credentials

curl -sS -X POST "https://api.superior.trade/v3/deployments/${DEPLOYMENT_ID}/credentials" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}" \
  -H "content-type: application/json" \
  -d '{ "wallet_address": "0xSuperiorManagedWallet" }'

The wallet address must be owned by the authenticated user. The response reports credentials_status: "stored" and exchange: "lighter". It does not return private keys.

Start or stop deployment

Before starting, verify:

1. GET /v3/account/{address}/status/lighter reports ready.
2. GET /v3/portfolio/lighter/balance?owner_address=... shows enough USDC for the strategy.
3. The deployment has credentials_status: "stored".
4. The user explicitly confirms live trading.

Show this confirmation before starting:

Deployment Summary:
* Strategy: [name]
* Exchange: lighter
* Runtime: Nautilus
* Instrument: [instrument_id]
* Owner wallet: [owner_address]
* Lighter balance: [balance] USDC

This will trade with REAL funds on Lighter. Proceed? (yes/no)

Start:

curl -sS -X PATCH "https://api.superior.trade/v3/deployments/${DEPLOYMENT_ID}/status" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}" \
  -H "content-type: application/json" \
  -d '{ "action": "start" }'

Stop:

curl -sS -X PATCH "https://api.superior.trade/v3/deployments/${DEPLOYMENT_ID}/status" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}" \
  -H "content-type: application/json" \
  -d '{ "action": "stop" }'

Monitor deployment

curl -sS "https://api.superior.trade/v3/deployments/${DEPLOYMENT_ID}" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}"

curl -sS "https://api.superior.trade/v3/deployments/${DEPLOYMENT_ID}/logs?pageSize=100" \
  -H "x-api-key: ${SUPERIOR_TRADE_API_KEY}"

Use logs and status responses to verify runtime health. Do not infer that a deployment is trading from a successful start response alone.

Error Handling

• 400 validation_failed: Fix request shape, especially venue, instrument_id, wallet addresses, amount precision, or idempotency input.
• 401 or 403: Check that SUPERIOR_TRADE_API_KEY is present and sent as x-api-key.
• 404 not_found: The Lighter feature can be disabled or the resource does not belong to the user.
• 409: A deposit is already active, a Lighter account is not ready, or the idempotency key was reused with different input.
• 502: Upstream Lighter lookup, intent creation, key provisioning, or withdrawal submission failed.

Related Skills

• Use superior-trade-auth first when the user needs an API key.
• Use trade-thesis before deploying a new live strategy idea.
• Use hyperliquid for Hyperliquid Freqtrade deployments. Lighter uses v3 Nautilus deployment APIs instead.
