# hyperliquid-trade

Trade spot and perpetual futures on Hyperliquid L1 using IOC market orders.

## When to Use

- **Spot**: buy or sell any token listed on Hyperliquid spot markets
- **Perps**: open long/short or close perpetual futures positions
- **Balance**: check spot token balances or perp positions and margin
- **Deposit**: bridge USDC from Arbitrum One to Hyperliquid L1

## External Communications

This skill connects to the Hyperliquid API (`api_url` in `hyperliquid.yaml`, default `https://api.hyperliquid.xyz`). Inform the user before the first external call in each session. On first setup, installs dependencies via `npm install`.

## Environment & Security Declaration

### Required config files

| File | Purpose |
|------|---------|
| `~/.aurehub/.wdk_vault` | WDK encrypted vault (created by xaut-trade setup) |
| `~/.aurehub/.wdk_password` | Vault password (mode 0600, created by xaut-trade setup) |
| `~/.aurehub/hyperliquid.yaml` | Network, API URL, risk thresholds |

### Optional environment variables (in `~/.aurehub/.env`)

| Variable | Purpose | Default |
|----------|---------|---------|
| `WDK_ACCOUNT_INDEX` | HD derivation index (0-based) for wallet address | `0` |
| `ARBITRUM_RPC_URL` | Arbitrum One JSON-RPC endpoint — required for `deposit.js` | *(none; public: `https://arb1.arbitrum.io/rpc`)* |

### Security safeguards

- Private key is decrypted from vault in memory only, never stored
- Decrypted key material zeroed from memory after use
- All external API responses treated as untrusted numeric data
- Every trade requires explicit user confirmation per thresholds in `hyperliquid.yaml`

## Environment Readiness Check (run first on every session)

`<skill-dir>` = directory containing this SKILL.md.
`<scripts-dir>` = `<skill-dir>/scripts`.

Run these checks before handling any intent (except knowledge queries):

| Step | Check | Type | Action |
|------|-------|------|--------|
| 1 | `~/.aurehub/.wdk_vault` exists | HARD STOP | Load [references/onboarding.md](references/onboarding.md) and guide the user through setup. |
| 2 | `~/.aurehub/.wdk_password` exists | HARD STOP | Load [references/onboarding.md](references/onboarding.md) and guide the user through setup. |
| 3 | `~/.aurehub/hyperliquid.yaml` exists | AUTO-FIX | `cp <skill-dir>/config.example.yaml ~/.aurehub/hyperliquid.yaml` |
| 4 | `node -e "const [maj,min]=process.version.slice(1).split('.').map(Number);if(maj<20||(maj===20&&min<19))process.exit(1)"` passes | HARD STOP | "Node.js >= 20.19.0 is required. Please upgrade." |
| 5 | `<scripts-dir>/node_modules` exists | AUTO-FIX | `cd <scripts-dir> && npm install` |
| 6 | `node <scripts-dir>/balance.js address` succeeds | HARD STOP | Report error JSON; load [references/onboarding.md](references/onboarding.md) |

If all pass: source `~/.aurehub/.env`, run **Account Selection** (below), then **Wallet-Ready Registration**, then proceed to intent detection.

## Account Selection

If the user specifies a wallet index (e.g. "use wallet 2", "account 1", "wallet 3"), remember that index for the entire session. Append `--account N` to **every** `node balance.js`, `node trade.js`, and `node limit-order.js` command in this session.

If the user does not specify an account, do not append `--account` — the default from `WDK_ACCOUNT_INDEX` in `.env` (or `0`) is used automatically.

## Wallet-Ready Registration

Run immediately after environment checks pass. Derive WALLET_ADDRESS from check 6's output (if an account was selected above, include `--account N`):

```bash
source ~/.aurehub/.env
WALLET_ADDRESS=$(node <scripts-dir>/balance.js address | node -p "JSON.parse(require('fs').readFileSync(0,'utf8')).address")
```

If this fails, skip registration silently and continue.

1. `REGISTERED=$(cat ~/.aurehub/.registered 2>/dev/null)`
2. If `"$REGISTERED"` starts with `"$WALLET_ADDRESS:"` → already registered, silent skip; return immediately
3. If `RANKINGS_OPT_IN` != `"true"`:
   - Check marker: `PROMPTED=$(cat ~/.aurehub/.rankings_prompted 2>/dev/null)`
   - If marker starts with `"$WALLET_ADDRESS:"` → skip; return immediately
   - Otherwise ask once: "Join XAUT activity rankings now? (yes/no)"
     - If user says `no`: `echo "$WALLET_ADDRESS:declined" > ~/.aurehub/.rankings_prompted`; return
     - If user says `yes`:
       - If `NICKNAME` is empty: ask user for nickname
       - Persist opt-in in `~/.aurehub/.env` (`RANKINGS_OPT_IN=true`, `NICKNAME=<value>`)
       - Re-source env: `source ~/.aurehub/.env`
       - Continue to step 4
4. If `RANKINGS_OPT_IN` == `"true"`:
   - If `NICKNAME` is empty: ask "You're opted in to XAUT activity rankings — what nickname would you like to appear as?", then persist to `~/.aurehub/.env` and re-source
   - Register:
   ```bash
   NICKNAME_ESC=$(printf '%s' "$NICKNAME" | sed 's/\\/\\\\/g; s/"/\\"/g')
   REGISTER_RESP=$(curl -s -o /dev/null -w "%{http_code}" -X POST \
     https://xaue.com/api/rankings/participants \
     -H 'Content-Type: application/json' \
     -d "{\"wallet_address\":\"$WALLET_ADDRESS\",\"nickname\":\"$NICKNAME_ESC\",\"source\":\"agent\"}")
   ```
   - HTTP 200 or 201: `echo "$WALLET_ADDRESS:$NICKNAME" > ~/.aurehub/.registered`; inform: "Registered with nickname: $NICKNAME"
   - Any other status: silent continue, do not write marker file

Only prompt once per wallet. The `.rankings_prompted` and `.registered` markers ensure idempotency across sessions.

## Intent Detection

| User says | Action |
|-----------|--------|
| buy ETH / purchase BTC / spot buy | `trade.js spot buy` |
| sell SOL / spot sell ETH | `trade.js spot sell` |
| long ETH / open long BTC 10x / go long | `trade.js perp open ... long` |
| short BTC / open short ETH / go short | `trade.js perp open ... short` |
| close position / close ETH / flat / exit | `trade.js perp close` (auto-detects direction) |
| balance / holdings / positions / how much / 查看余额 / 查看持仓 / 持仓 | **Always run both**: `balance.js spot` + `balance.js perp`. Never return only one. |
| setup / onboarding / first time | Load [references/onboarding.md](references/onboarding.md) |
| Insufficient info (no coin or amount) | Ask for the missing details before proceeding |
| limit buy ETH at 3000 / limit order / limit sell | Load [references/limit-order.md](references/limit-order.md); run `limit-order.js place` |
| open orders / my orders / list orders | Load [references/limit-order.md](references/limit-order.md); run `limit-order.js list` |
| cancel order / cancel limit | Load [references/limit-order.md](references/limit-order.md); run `limit-order.js cancel` |
| change order price / update order / modify order | Load [references/limit-order.md](references/limit-order.md); run `limit-order.js modify` |
| deposit USDC / fund wallet / bridge USDC / 充值 / 存款 / 往 HL 存钱 | Run `deposit.js` flow (see **Deposit Flow** below) |
| withdraw USDC / withdraw to Arbitrum / 提现 / 取款 / 把钱取出来 | Run `withdraw.js` flow (see **Withdraw Flow** below) |

## Resolving HL_SCRIPTS_DIR

Use `<skill-dir>/scripts` as the scripts directory. To find `<skill-dir>` at runtime:

```bash
# 1. Git repo fallback
GIT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)
[ -n "$GIT_ROOT" ] && [ -d "$GIT_ROOT/skills/hyperliquid-trade/scripts" ] && HL_SCRIPTS_DIR="$GIT_ROOT/skills/hyperliquid-trade/scripts"
# 2. Bounded home search
[ -z "$HL_SCRIPTS_DIR" ] && HL_SCRIPTS_DIR=$(dirname "$(find -L "$HOME" -maxdepth 6 -type f -path "*/hyperliquid-trade/scripts/balance.js" 2>/dev/null | head -1)")
echo "$HL_SCRIPTS_DIR"
```

## Balance Flow

Load [references/balance.md](references/balance.md) for the full flow.

```bash
node "$HL_SCRIPTS_DIR/balance.js" spot
node "$HL_SCRIPTS_DIR/balance.js" perp
```

Parse the JSON output and present balances in a human-readable table.

## Spot Trade Flow

Load [references/spot-trade.md](references/spot-trade.md) for the full flow.

1. Confirm intent: coin, direction (buy/sell), size
2. Run balance check to verify sufficient USDC/token
3. Run: `node "$HL_SCRIPTS_DIR/trade.js" spot <buy|sell> <COIN> <SIZE>`
4. Read preview JSON; apply confirmation logic per `requiresConfirm`/`requiresDoubleConfirm` flags (same as limit orders)
5. After user confirms, re-run: `node "$HL_SCRIPTS_DIR/trade.js" spot <buy|sell> <COIN> <SIZE> --confirmed`
6. Use the last JSON line as the result; report fill price and outcome
7. **After a spot buy**: `filledSz` in the result reflects the ordered quantity, not the net-of-fees received amount (Hyperliquid deducts taker fees ~0.035% from the received tokens). If the user immediately wants to sell, run `balance.js spot` first to get the actual available balance and use that as the sell size.

## Perp Trade Flow

Load [references/perp-trade.md](references/perp-trade.md) for the full flow.

**Open position:**
1. Confirm intent: coin, direction (long/short), size, leverage, margin mode
2. Run: `node "$HL_SCRIPTS_DIR/trade.js" perp open <COIN> <long|short> <SIZE> [--leverage <N>] [--cross|--isolated]`
3. Read preview JSON; apply confirmation logic per `requiresConfirm`/`requiresDoubleConfirm` flags
4. After user confirms, re-run with `--confirmed`; use the last JSON line as the result

**Close position:**
1. Show current position from `balance.js perp`; confirm size to close
2. Run: `node "$HL_SCRIPTS_DIR/trade.js" perp close <COIN> <SIZE>`
3. Read preview JSON; apply confirmation logic
4. After user confirms, re-run with `--confirmed`; use the last JSON line as the result

## Confirmation Thresholds

Thresholds are read from `~/.aurehub/hyperliquid.yaml`. Defaults: `confirm_trade_usd=100`, `large_trade_usd=1000`, `leverage_warn=20`.

For **spot**: threshold applies to trade value (size × est. price).
For **perps**: threshold applies to margin deposited (size × est. price ÷ leverage).

```
< confirm_trade_usd    →  show preview, execute without prompting
≥ confirm_trade_usd    →  show preview, single confirmation
≥ large_trade_usd      →  show preview, double confirmation required
leverage ≥ leverage_warn  →  extra warning line before confirmation
```

Trade preview format (present to user before prompting):
```
Action:      <Open Long ETH (Perpetual) | Buy ETH (Spot)>
Size:        <0.1 ETH>
Leverage:    <10x Cross>           ← perp only
Est. price:  ~$<3,200>  (IOC, <slippage_pct>% slippage budget — default 5%, configurable in hyperliquid.yaml)
Margin used: ~$<320> USDC         ← perp only
Trade value: ~$<320> USDC         ← spot only
Confirm? [y/N]
```

`trade.js` outputs this as a `preview` JSON object. Parse the JSON and render the above format before prompting. Apply `requiresConfirm`/`requiresDoubleConfirm` flags for confirmation logic; if `leverageWarning: true`, add an extra warning line about high leverage; if `leverageChangeWarning: true`, add a warning: "Note: this leverage setting takes effect immediately and will apply to all existing cross-margin positions for this coin."

## Hard Stops

| Condition | Message |
|-----------|---------|
| Insufficient balance | "Insufficient balance: have $X, need $Y. Deposit at app.hyperliquid.xyz to top up." |
| Asset not found | "Asset X not found on Hyperliquid. Check the symbol and try again." |
| Leverage exceeds asset max | "Max leverage for ETH is Nx. Requested: Mx." |
| No open position (close) | "No open position found for ETH." |
| IOC order not filled | Relay the script's error verbatim — it includes the configured slippage % (e.g. "Order not filled — price moved beyond the 5% IOC limit. Check current price and retry.") |
| Node.js < 20.19 | "Node.js >= 20.19.0 required. Please upgrade: https://nodejs.org" |
| API unreachable | "Hyperliquid API unreachable. Check network or `api_url` in `~/.aurehub/hyperliquid.yaml`." |

## Deposit Flow

Bridges USDC from Arbitrum One to Hyperliquid L1 using the HL bridge contract.
The same wallet address receives USDC on HL within ~1 minute.

**Prerequisites:**
- `ARBITRUM_RPC_URL` must be set in `~/.aurehub/.env` (e.g. `https://arb1.arbitrum.io/rpc`)
- Wallet must have USDC on Arbitrum One (native USDC, not USDC.e)
- Wallet must have a small amount of ETH on Arbitrum One for gas

**Steps:**

1. Confirm intent: amount in USDC (minimum 5 USDC — amounts below minimum are permanently lost)
2. Check `ARBITRUM_RPC_URL` is set; if missing, instruct user to add it to `~/.aurehub/.env` and stop
3. Run preview: `node "$HL_SCRIPTS_DIR/deposit.js" <amount>`
4. Parse preview JSON; apply confirmation logic per `requiresConfirm`/`requiresDoubleConfirm` flags
5. After user confirms, re-run with `--confirmed`
6. Report the `txHash` and credit note from the result

**Preview format (render before prompting):**
```
Action:       Deposit USDC → Hyperliquid L1
Amount:       <100> USDC
From/To:      <0x...> (same address on HL)
USDC balance: <150.00> USDC (Arbitrum)
ETH balance:  <0.005> ETH (Arbitrum, for gas)
Credit time:  ~1 minute
Confirm? [y/N]
```

**Hard stops:**

| Condition | Message |
|-----------|---------|
| `ARBITRUM_RPC_URL` not set | "Add ARBITRUM_RPC_URL to ~/.aurehub/.env first. Public RPC: https://arb1.arbitrum.io/rpc" |
| Amount < 5 USDC | "Minimum deposit is 5 USDC. Smaller amounts are permanently lost by the bridge." |
| Insufficient USDC | "Insufficient USDC on Arbitrum. Have $X, need $Y." |
| No ETH for gas | "No ETH on Arbitrum One for gas. Bridge a small amount of ETH to Arbitrum first." |
| Wrong network | "ARBITRUM_RPC_URL points to wrong network. Must be Arbitrum One (chainId 42161)." |

## Withdraw Flow

Withdraws USDC from Hyperliquid L1 to Arbitrum One. Funds arrive at the same wallet address within ~5 minutes. A **1 USDC fee** is deducted by the bridge; no ETH is required.

**Steps:**

1. Confirm intent: amount in USDC (minimum 2 USDC — 1 USDC fee is deducted, so at least 1 USDC arrives)
2. Run preview: `node "$HL_SCRIPTS_DIR/withdraw.js" <amount>`
3. Parse preview JSON; apply confirmation logic per `requiresConfirm`/`requiresDoubleConfirm` flags
4. After user confirms, re-run with `--confirmed`
5. Report the net received amount and credit note

**Preview format (render before prompting):**
```
Action:       Withdraw USDC → Arbitrum One
Amount:       <10> USDC
Fee:          1 USDC (bridge fee)
Net received: <9> USDC
USDC balance: <13.63> USDC (Hyperliquid L1)
Withdrawable: <13.63> USDC
Credit time:  ~5 minutes
Confirm? [y/N]
```

**Hard stops:**

| Condition | Message |
|-----------|---------|
| Amount < 2 USDC | "Minimum withdrawal is 2 USDC (1 USDC fee is deducted)." |
| Insufficient withdrawable | "Insufficient withdrawable balance. Have $X, need $Y." |
| Margin locked | Append: "X USDC is locked as perp margin. Close positions to free up more." |

## Limit Order Flow

Load [references/limit-order.md](references/limit-order.md) for the full flow.

**Place a limit order:**
1. Confirm intent: coin, direction, price, size (ask for any missing details)
2. Run: `node "$HL_SCRIPTS_DIR/limit-order.js" place <spot|perp> <buy|sell|long|short> <COIN> <PRICE> <SIZE> [--leverage N] [--cross|--isolated]`
3. Read the `preview` JSON; apply confirmation logic per `references/limit-order.md`
4. After user confirms, re-run with `--confirmed` flag
5. Report fill outcome and order ID

**List / cancel / modify:**
1. Run the appropriate `limit-order.js` subcommand
2. For modify: always show a preview and ask for user confirmation before executing
3. When re-running modify with `--confirmed`, the script emits the preview JSON line first, then the result — use the **last** JSON line as the result
4. After a successful modify, the order ID changes (`oid` in the result is the new ID); update any stored order ID accordingly
5. Parse JSON and present result in a human-readable format
