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

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

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)

= directory containing this SKILL.md.

= /scripts.

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

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):

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=)
• 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

Resolving HL_SCRIPTS_DIR

Use /scripts as the scripts directory. To find at runtime:

# 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 for the full flow.

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 for the full flow.

1. Confirm intent: coin, direction (buy/sell), size
2. Run balance check to verify sufficient USDC/token
3. Run: node "$HL_SCRIPTS_DIR/trade.js" spot
4. Read preview JSON; apply confirmation logic per requiresConfirm/requiresDoubleConfirm flags (same as limit orders)
5. After user confirms, re-run: node "$HL_SCRIPTS_DIR/trade.js" spot --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 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 [--leverage ] [--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
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

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"
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:

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"
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:

Limit Order Flow

Load 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 [--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
