Skill: jgramajo4/aave-liquidation-monitor (version 1.0.1)

--- name: aave-liquidation-monitor description: "Proactive monitoring of Aave V3 borrow positions with liquidation alerts. Queries user collateral, debt, and health factor across chains (Ethereum, Polygon, Arbitrum, etc.). Sends urgent alerts to Telegram/Discord/Slack when health factor drops below configurable thresholds (critical at 1.05, warning at 1.2). Use when you need continuous monitoring of Aave positions, want alerts before liquidation risk occurs, or need periodic summaries of your borrowing health." --- # Aave Liquidation Monitor ## Quick Start Configure your wallet and thresholds once, then the skill runs automatically every 6 hours (configurable). ### Step 1: Initialize Your Config Run `/aave-config init` to set up: - Your Ethereum wallet address (read-only; no private keys required) - Health factor thresholds (default: critical 1.05, warning 1.2, stable >1.5) - Check interval in hours (default: 6) - Notification verbosity (verbose = daily summaries even if stable; quiet = only alerts) - Preferred notification channel (Telegram default, or specify Discord/Slack) Example: ``` /aave-config init → Wallet: 0x1234...5678 → Thresholds: 1.05 (critical), 1.2 (warning) → Interval: 6 hours → Verbosity: quiet (alerts only) → Channel: telegram ``` ### Step 2: Test the Monitor Run `/aave-monitor check` to fetch your position immediately and see the alert format: ``` /aave-monitor check → Fetching position for 0x1234...5678 on Ethereum... → Health Factor: 2.31 (Stable ✓) → Total Collateral: $50,342.12 → Total Debt: $21,804.00 → Borrowed Assets: USDC (15,000), WETH (0.5), USDT (6,804) → Supplied Assets: WETH (10), USDC (20,000), DAI (30,000) ``` ### Step 3: Enable Proactive Monitoring Run `/aave-monitor enable` to start automatic checks every 6 hours. The skill registers a cron job that silently runs in the background and alerts you only when health factor drops below threshold. For manual override: ``` /aave-monitor enable --interval 4 # Check every 4 hours /aave-monitor disable # Stop monitoring /aave-monitor status # See current config + last check result ``` ## Configuration Reference See `references/config-guide.md` for detailed config options, chain support, and threshold guidance. See `references/aave-api.md` for Aave V3 GraphQL schema and query patterns. **Security & Credentials:** See `SECURITY.md` for how credentials are handled and threat model. **For auditors:** See `SECURITY.md` for code review checklist and architecture details. ## How It Works 1. **Query Phase**: Calls Aave V3 GraphQL API with your wallet address 2. **Analysis Phase**: Extracts health factor, collateral, debt, borrowed/supplied assets 3. **Alert Logic**: - If HF < 1.05 → **CRITICAL** (red alert, send immediately) - If HF < 1.2 → **WARNING** (yellow alert, send immediately) - If HF > 1.5 → **STABLE** (no alert, unless verbose mode enables daily summary) 4. **Notification Phase**: Posts alert to your configured channel with clear summary 5. **Retry Logic**: If API fails, retries up to 3 times with exponential backoff ## Error Handling - **Invalid wallet address** → Logs error, skips check, retries next interval - **API timeout** → Retries up to 3x with exponential backoff (2s, 4s, 8s) - **Malformed response** → Alerts you to API changes, logs full response for debugging - **Network errors** → Silently retries; alerts only if all retries fail ## Security & Credentials **NO private keys are requested or stored** — this is read-only monitoring only. ### How messaging credentials work The skill uses **OpenClaw's built-in message routing** — it does NOT store Telegram, Discord, or Slack tokens. 1. You configure your messaging channel in OpenClaw (outside this skill) 2. The skill calls OpenClaw's messaging API with just the alert text 3. OpenClaw routes the message using your configured channels Example: ``` /aave-config set channel telegram → OpenClaw sends alerts via your pre-configured Telegram channel ``` **You must have a messaging channel already set up in OpenClaw.** See OpenClaw docs for setting up Telegram/Discord/Slack integrations. ### Data handling - **Wallet address:** Stored in OpenClaw's encrypted config (never sent to external services except Aave's public API) - **API responses:** Parsed for health factor only; sensitive position data is NOT logged - **Credentials:** Managed by OpenClaw, never stored in skill files ### What the skill accesses ✅ **Aave GraphQL API (public)** — reads your position data ✅ **OpenClaw message routing** — sends formatted alerts to your configured channel ✅ **Cron scheduler** — runs background checks on your interval ❌ **Does NOT:** - Request private keys - Store API tokens - Execute transactions - Modify your positions ## Examples ### Alert Examples **Critical Alert (HF < 1.05):** ``` 🚨 AAVE LIQUIDATION RISK – CRITICAL Health Factor: 1.02 (Liquidation threshold: 1.0) ⏰ Action required immediately! 📊 Position Summary: Total Collateral: $50,000 Total Debt: $48,000 Debt Ratio: 96% Borrowed (at risk): - USDC: 40,000 - WETH: 8 ETH (~$31k) Suggested Actions: 1. Repay debt (especially WETH) 2. Supply more collateral 3. Enable eMode if available (higher LTV on correlated assets) Last checked: 2026-02-11 08:15 UTC ``` **Warning Alert (HF < 1.2):** ``` ⚠️ AAVE WARNING Health Factor: 1.15 (Approaching 1.2 threshold) Position approaching liquidation. Consider: - Repaying $2,000 USDC or - Adding $5,000 collateral (WETH or stETH) ``` **Stable Position (HF > 1.5, verbose mode only):** ``` ✅ AAVE POSITION HEALTHY Health Factor: 2.31 Total Collateral: $50,342.12 Total Debt: $21,804.00 All clear. Check again tomorrow. ``` ### Command Examples ```bash # One-time position check /aave-monitor check # Start automatic monitoring /aave-monitor enable # Change thresholds (e.g., earlier warning at HF 1.3) /aave-config set thresholds 1.05 1.3 # Check monitoring status /aave-monitor status # View last 5 check results with alerts /aave-monitor history 5 # Disable monitoring temporarily /aave-monitor disable ``` ## Chains Supported Primary: Ethereum mainnet Also works (with same config address where applicable): - Polygon - Arbitrum - Optimism - Base - Avalanche - Gnosis Edit `scripts/monitor.js` to add chains or customize per-chain endpoints. ## Customization **Change check interval:** ``` /aave-config set interval 4 # Check every 4 hours ``` **Change alert thresholds:** ``` /aave-config set thresholds 1.1 1.25 # Critical at 1.1, warning at 1.25 ``` **Enable verbose mode (daily summaries even if stable):** ``` /aave-config set verbosity verbose ``` **Switch notification channel:** ``` /aave-config set channel discord ``` ## Implementation Details See `scripts/monitor.js` for the core monitoring logic (GraphQL queries, health factor calculation, alert formatting). See `scripts/cron-runner.js` for cron job integration with OpenClaw's cron scheduler. ## Troubleshooting **"Invalid wallet address"** → Check format: must be 0x... format. Try `/aave-config view` to see current config. **"Health factor not returned by API"** → Wallet may not have Aave position. Try `/aave-monitor check` for immediate response. **"API endpoint unreachable"** → Aave API may be down. Skill retries automatically. Check https://status.aave.com. **"No notifications sent"** → Check that your notification channel is active. Run `/aave-monitor check` to test delivery. ## Notes - Health factor = Total Collateral / Total Debt (net of liquidation threshold ratios) - Liquidation occurs when HF ≤ 1.0 - Variable debt accrues interest; stable debt is fixed-rate - eMode allows higher LTV for correlated assets (e.g., stablecoins, ETH-LSTs) - Supplied assets are collateral; they earn interest but can be seized if you're liquidated --- **Last Updated:** 2026-02-11 | **Status:** Ready for configuration

## Installation Steps

### Step 0: Verify Prerequisites

Before using this skill, you must have:

1. ✅ **OpenClaw installed and running** (v1.0+)
2. ✅ **A messaging channel configured** (Telegram, Discord, or Slack)
   - The skill sends alerts through OpenClaw's existing channel integrations
   - No API tokens are stored in the skill itself
3. ✅ **Your Ethereum wallet address** (the one with Aave positions)

**No private keys or credentials go in this skill.** All credentials are managed by OpenClaw.

### Step 1: Install the Skill

Option A: Via ClawhHub CLI (recommended):
```bash
clawhub install aave-liquidation-monitor
```

Option B: Copy to workspace:
```bash
cp -r /home/goliso/clawd/skills/aave-liquidation-monitor \
  ~/.nvm/versions/node/v24.13.0/lib/node_modules/openclaw/skills/
```

### Step 2: Verify Installation

```bash
# Check that OpenClaw can discover the skill
openclaw skills list | grep aave

# Should output:
# aave-liquidation-monitor - Proactive monitoring of Aave V3...
```

### Step 3: Initialize Configuration

Run this command in OpenClaw (via Telegram, Discord, or CLI):

```bash
/aave-config init
```

You'll be prompted for:
1. **Ethereum wallet address** (the one with Aave positions)
2. **Health factor thresholds** (defaults: critical 1.05, warning 1.2)
3. **Check interval** (default: 6 hours)
4. **Notification verbosity** (default: quiet = alerts only)
5. **Notification channel** (default: telegram)

Example input:
```
→ Wallet: 0x1234567890abcdef1234567890abcdef12345678
→ Thresholds: critical=1.05 warning=1.2
→ Interval: 6
→ Verbosity: quiet
→ Channel: telegram
✅ Config saved!
```

### Step 4: Test the Monitor

Run a manual check to ensure everything works:

```bash
/aave-monitor check
```

Expected output:
```
Health Factor: 2.31 (Stable ✓)
Total Collateral: $50,342.12
Total Debt: $21,804.00
Debt Ratio: 43.3%

Borrowed Assets:
  USDC: 15,000
  WETH: 0.5
  USDT: 6,804

Supplied Assets:
  WETH: 10
  USDC: 20,000
  DAI: 30,000
```

If you get an error:
- **"Invalid wallet address"** → Check format: must be `0x` + 40 hex chars
- **"No user account found"** → Wallet has no Aave position, or wrong chain selected
- **"API error"** → Aave API might be temporarily down; try again in a minute

### Step 5: Enable Automatic Monitoring

```bash
/aave-monitor enable
```

The skill now runs checks every 6 hours (or your configured interval). Alerts are sent automatically to your channel when health factor drops below threshold.

Status: ✅ Monitoring active!

## Configuration Examples

### Example 1: High-Leverage Trading (Frequent Monitoring)

You're actively borrowing on Aave and want early warnings.

```bash
/aave-config set checkInterval 3        # Check every 3 hours
/aave-config set thresholds critical=1.1 warning=1.15
/aave-config set verbosity verbose      # Daily summaries too
/aave-monitor disable
/aave-monitor enable
```

Result: Alerts every 3 hours if HF < 1.15; daily position summary if HF > 1.5.

### Example 2: Long-Term Lender (Minimal Alerts)

You supplied collateral but rarely borrow. Just want danger alerts.

```bash
/aave-config set checkInterval 12       # Check every 12 hours
/aave-config set thresholds critical=1.05 warning=1.3
/aave-config set verbosity quiet        # Alerts only
/aave-monitor disable
/aave-monitor enable
```

Result: Silent monitoring 2x daily; alerts only if HF drops below 1.3.

### Example 3: Monitor Multiple Chains

Monitor the same wallet address on both Ethereum and Polygon:

```bash
# Check which chains you're using
/aave-monitor check --chain ethereum
/aave-monitor check --chain polygon

# Create separate monitoring jobs (future feature)
# For now, manually check each chain:
/aave-monitor check --chain polygon
```

---

## Alert Examples

You'll receive messages like these when your health factor is at risk:

### 🚨 Critical Alert (HF < 1.05)

```
🚨 AAVE LIQUIDATION RISK – CRITICAL
Chain: Ethereum
Health Factor: 1.02 (Liquidation at ≤1.0!)
⏰ ACTION REQUIRED IMMEDIATELY

Position Summary:
Total Collateral: $50,000
Total Debt: $48,000
Debt Ratio: 96%

Borrowed Assets:
  USDC: 40,000
  WETH: 8 ETH

Actions:
1. Repay debt (especially WETH)
2. Supply more collateral
3. Enable eMode (higher LTV for correlated assets)

Checked: 2026-02-11 08:15 UTC
```

### ⚠️ Warning Alert (HF 1.05–1.2)

```
⚠️ AAVE WARNING
Health Factor: 1.15
Position approaching liquidation zone.

Suggested Actions:
- Repay $2,000 USDC, OR
- Supply $5,000+ collateral (WETH, stETH, etc.)

Check back: 2026-02-11 14:00 UTC
```

### ✅ Healthy Position (HF > 1.5, verbose mode only)

```
✅ AAVE POSITION HEALTHY
Health Factor: 2.31
Total Collateral: $50,342
Total Debt: $21,804
Debt Ratio: 43%

Position is stable. ✨ All clear.
Next check: tomorrow at same time.
```

## Troubleshooting

### Problem: "Config not found - run `/aave-config init` first"

**Solution:**
```bash
/aave-config init
```

Then answer the setup prompts.

### Problem: "API Error – retrying"

**Cause:** Aave API temporarily unreachable.

**Solution:** Automated retries happen. If it persists:
1. Check https://status.aave.com
2. Run `/aave-monitor check` to test manually
3. Monitoring will resume on next interval

### Problem: Alerts go to wrong channel

**Cause:** Channel config doesn't match active channels.

**Solution:**
```bash
/aave-config view channels    # List available channels
/aave-config set channel discord
/aave-monitor disable
/aave-monitor enable          # Recreate job
```

### Problem: I want to monitor a different wallet

**Solution:**
```bash
/aave-config set walletAddress 0xnewaddress...
/aave-monitor disable
/aave-monitor enable          # Restart with new address
```

### Problem: Alerts are too frequent (or not frequent enough)

**Solution:** Adjust interval:
```bash
/aave-config set checkInterval 4  # Change to 4 hours
/aave-monitor disable
/aave-monitor enable
```

path: SECURITY.md
content: # Security Practices

## What This Skill Does NOT Do

❌ **No private keys** — Never requests or stores your seed phrase, private key, or signing credentials  
❌ **No signing** — Never executes transactions on-chain  
❌ **No token storage** — Telegram/Discord/Slack tokens are managed by OpenClaw, not this skill  
❌ **No sensitive logging** — API responses are parsed safely; position data is NOT logged  

## What This Skill Does

✅ **Read-only monitoring** — Queries Aave's public GraphQL API for position data  
✅ **Uses OpenClaw's message routing** — Sends alerts through your configured channels  
✅ **Local config storage** — Wallet address stored in OpenClaw's encrypted preferences  
✅ **Background monitoring** — Registers a cron job for automated checks  

---

## Architecture & Data Flow

### 1. Initial Setup (`/aave-config init`)

```
User provides wallet address
        ↓
OpenClaw stores in encrypted config (~/.openclaw/prefs)
        ↓
Wallet address never sent anywhere except Aave API
```

**Security:** Wallet addresses are public blockchain data; encryption protects them from local disk access only.

### 2. Monitoring Check (`/aave-monitor check` or cron interval)

```
Cron job triggers
        ↓
monitor.js reads wallet from OpenClaw config
        ↓
Fetches position from https://api.v3.aave.com/graphql
        ↓
Parses response for: health factor, collateral, debt
        ↓
Formats alert message (no sensitive data logged)
        ↓
Returns message to OpenClaw
        ↓
OpenClaw routes to Telegram/Discord/Slack via configured channel
```

**Security:**
- Only health factor and asset amounts are extracted
- Full API response is NOT logged
- No credentials are passed to external services
- OpenClaw's messaging system handles channel credentials

### 3. Alert Delivery

```
monitor.js returns alert message
        ↓
OpenClaw's cron system receives result
        ↓
OpenClaw routes via pre-configured Telegram/Discord/Slack
        ↓
Alert reaches your device
```

**Security:** Skill has zero access to messaging tokens. OpenClaw handles all credentials.

---

## Code Review Checklist

For security reviewers, here's what to verify:

### Scripts

**scripts/monitor.js**
- ✅ Only fetches from `https://api.v3.aave.com/graphql` (Aave public API)
- ✅ No private key handling
- ✅ No logging of full API responses
- ✅ Error messages don't include sensitive data
- ✅ Returns only parsed data (HF, collateral, debt, asset names)

**scripts/cron-runner.js**
- ✅ No credential storage
- ✅ Returns structured result for OpenClaw routing
- ✅ No external messaging calls (uses OpenClaw's system)

### Configuration

**assets/config-template.json**
- ✅ No API keys or tokens
- ✅ Wallet address marked as configuration (not hardcoded)
- ✅ Thresholds and intervals are user-configurable

### Documentation

**SKILL.md**
- ✅ Clearly states "no private keys"
- ✅ Explains credential handling via OpenClaw
- ✅ Documents what data is stored where

---

## Threat Model

### Attacks Mitigated

**Compromised OpenClaw instance:**
- Your wallet address is readable from encrypted config
- But attacker can only READ public position data (no signing possible)
- Messaging tokens remain in OpenClaw's systems, not this skill

**Man-in-the-middle (MITM):**
- Aave API uses HTTPS/TLS
- OpenClaw messaging uses HTTPS/TLS
- No credentials transmitted by this skill

**Malicious skill code:**
- Skill code is auditable (open source)
- Credentials are managed by OpenClaw, not passed to skill
- Skill can only send alerts; cannot modify Aave positions

### Assumptions

1. **OpenClaw is trustworthy** — Credentials stored in OpenClaw are handled securely
2. **Aave API is trustworthy** — Public API is from Aave Foundation
3. **HTTPS works** — TLS connections are not compromised
4. **User machine is not fully compromised** — If attacker has full local access, they can steal anything

---

## Configuration & Storage

### Wallet Address Storage

- **Where:** `~/.openclaw/prefs/aaveLiquidationMonitor.json` (encrypted at rest)
- **What:** Your Ethereum wallet address (public data)
- **Risk:** Low — wallet addresses are public blockchain data
- **Why encrypted:** To prevent casual disk inspection

### Messaging Channel

- **Where:** Configured in OpenClaw's settings (outside this skill)
- **Token storage:** OpenClaw's credential manager, NOT this skill
- **Risk:** OpenClaw's responsibility, not this skill's

### Logs

- **Health factor checks:** Logged to OpenClaw session history
- **Sensitive data:** NOT logged (wallet positions, API responses)
- **Retention:** Follows OpenClaw's log retention policy

---

## What Requires User Awareness

Users should understand:

1. **Public data:** Your wallet address is visible on-chain; monitoring it publicly is your choice
2. **Alert delivery:** Whoever has access to your Telegram/Discord/Slack account can see alerts
3. **Background execution:** Cron job runs every 6 hours; network requests go to Aave API
4. **Logging:** Your health factor is logged in OpenClaw's session history
5. **Prerequisites:** This skill relies on OpenClaw's messaging integrations being set up correctly

---

## Recommended User Setup

For maximum security:

1. ✅ Use a **read-only address** (not your hot wallet with signing keys)
2. ✅ Ensure your **Telegram/Discord/Slack channel is private**
3. ✅ Keep **OpenClaw updated** to get security patches
4. ✅ Review **OpenClaw logs** periodically
5. ✅ Don't share **ClawhHub links with untrusted sources**

---

## Incident Response

If something seems wrong:

1. **Disable monitoring immediately:**
   ```bash
   /aave-monitor disable
   ```

2. **Check logs for anomalies:**
   ```bash
   /aave-monitor logs 50
   ```

3. **Review OpenClaw audit trail:**
   ```bash
   /sessions history
   ```

4. **Reset configuration:**
   ```bash
   /aave-config reset
   /aave-config init
   ```

---

## Contact & Reporting

Found a security issue? 

- Do NOT disclose publicly
- Report directly to the skill maintainer via GitHub issues (private if available)
- Include: severity, description, reproduction steps
- Allow time for patches before public disclosure

---

## Versions & Updates

- **v1.0.0:** Initial release
- All releases are version-controlled and auditable on ClawhHub
- Security patches are released as semver updates

---

**Last updated:** 2026-02-11  
**Security level:** Transparent design, no credential storage in skill

  "currentTotalDebt": "15000000000",  // 15,000 USDC (6 decimals)
  "currentVariableDebt": "10000000000",  // Variable
  "currentStableDebt": "5000000000"   // Stable
}
```

To convert: `15000000000 / (10 ^ 6) = 15000 USDC`

#### Sub-field: `supplies` (Supplied Assets / Collateral)

Array of assets you've supplied to Aave. Each supply contains:

| Field | Type | Description |
|-------|------|-------------|
| `reserve.symbol` | String | Asset symbol (e.g., "WETH", "USDC", "aEth") |
| `reserve.decimals` | Int | Decimal places |
| `reserve.price.priceInEth` | String (Ray) | Price in ETH |
| `scaledBalance` | String | Scaled balance (interest-bearing) |
| `balance` | String | Actual balance in asset units |

**Example:**
```json
{
  "symbol": "WETH",
  "decimals": 18,
  "balance": "10000000000000000000"  // 10 WETH (18 decimals)
}
```

To convert: `10000000000000000000 / (10 ^ 18) = 10 WETH`

---

## Key Calculations

### Health Factor (HF)

**Formula:**
```
HF = Total Collateral × Avg Liquidation Threshold / Total Debt
```

Aave returns `healthFactor` directly as a Ray (10^27). To convert to decimal:

```javascript
const hfDecimal = parseInt(healthFactor) / 1e27;
```

**Examples:**
- HF = 2.0 → Safe (20% buffer above liquidation)
- HF = 1.2 → Warning (only 20% buffer)
- HF = 1.05 → Critical (5% buffer)
- HF = 1.0 → Liquidation threshold (liquidators can seize)
- HF < 1.0 → Liquidation in progress

### Debt Ratio

```javascript
const totalDebtEth = parseInt(totalDebtBase) / 1e27;
const totalCollateralEth = parseInt(totalCollateralBase) / 1e27;
const debtRatio = (totalDebtEth / totalCollateralEth) * 100;
```

Example: 60% debt ratio = you borrowed 60% of your collateral value.

### Converting Ray Values to Decimals

Aave uses Ray (10^27) for large precision. To convert:

```javascript
// For totalCollateralBase, totalDebtBase (already in base currency, ETH)
const valueInEth = parseInt(valueString) / 1e27;

// For asset amounts (use decimals)
const valueInAsset = parseInt(valueString) / (10 ** decimals);

// For healthFactor
const hf = parseInt(healthFactor) / 1e27;
```

## Error Responses

### GraphQL Error: Invalid Address

```json
{
  "errors": [
    {
      "message": "Invalid user address format"
    }
  ]
}
```

**Solution:** Ensure address is `0x` + 40 hex chars.

### GraphQL Error: User Not Found

```json
{
  "data": {
    "userAccount": null
  }
}
```

**Meaning:** Wallet has no Aave position on this chain. Either:
- No supplies/borrows
- Wrong chain selected
- Wrong wallet address

### HTTP Error: 503 Service Unavailable

```
Status: 503
Body: Service temporarily unavailable
```

**Handling:** Retry with exponential backoff. Aave API is generally reliable (99.9% uptime).

---

## Example Request/Response

### Request

```bash
curl -X POST https://api.v3.aave.com/graphql \
  -H "Content-Type: application/json" \
  -d '{
    "query": "query GetUserPosition($address: String!) { userAccount(id: $address) { healthFactor totalCollateralBase totalDebtBase } }",
    "variables": {
      "address": "0x1234567890abcdef1234567890abcdef12345678"
    }
  }'
```

### Response (200 OK)

```json
{
  "data": {
    "userAccount": {
      "healthFactor": "2310000000000000000000000000",
      "totalCollateralBase": "50342120000000000000000000000",
      "totalDebtBase": "21804000000000000000000000000"
    }
  }
}
```

**Converted to decimals:**
- HF: 2.31
- Total Collateral: $50,342.12 (in ETH equivalent)
- Total Debt: $21,804 (in ETH equivalent)

---

## Performance Notes

- **Latency:** Typically 200–500ms per request
- **Rate Limits:** No strict public rate limits; but don't spam (>1000 req/min flagged)
- **Caching:** Aave data updates on-chain every block (~12 seconds on Ethereum)
- **Recommendations:**
  - Check every 6 hours for stable positions
  - Check every 2–4 hours for leveraged positions
  - Cache results for 1–5 minutes if querying frequently

---

## Future Enhancements

Aave GraphQL API support for:
- eMode status and LTV
- Isolated collateral info
- Flash loan eligibility
- Interest rate mode details
- Cooldown periods on collateral

Check Aave docs for latest schema: https://aave.com/docs



path: references/config-guide.md
content: # Aave Liquidation Monitor – Configuration Guide

## Initial Setup: `/aave-config init`

Running `/aave-config init` will prompt you through these fields:

### 1. Ethereum Wallet Address

**Field:** `walletAddress`

Your Ethereum wallet address (read-only, no private key needed).

Format: `0x` followed by 40 hex characters

Example: `0x1234567890abcdef1234567890abcdef12345678`

**Where to find it:**
- Metamask: Click account → copy address
- Etherscan: Search your ENS name or address at etherscan.io
- Hardware wallet: Check your wallet's address display

**Security note:** This address is public blockchain data. It's written locally in OpenClaw config but never sent to external services except Aave's public GraphQL API.

### 2. Health Factor Thresholds

**Field:** `thresholds`

Three threshold levels (in order of severity):

- **Critical Threshold** (default: `1.05`)
  - Triggers urgent alert when HF drops below this
  - Liquidation happens at HF ≤ 1.0, so 1.05 gives you ~5% buffer
  - Suggested range: 1.02–1.10

- **Warning Threshold** (default: `1.2`)
  - Triggers warning alert (less urgent) when HF drops below this
  - Should be higher than critical; gives you time to react
  - Suggested range: 1.15–1.5

- **Stable Threshold** (default: `1.5`)
  - Above this, position is considered safe
  - Used only in verbose mode to decide if daily summary is needed
  - Suggested range: 1.3–2.0

Example config:
```json
{
  "thresholds": {
    "critical": 1.05,
    "warning": 1.2,
    "stable": 1.5
  }
}
```

**Why these matter:**
- Aave liquidation happens when HF ≤ 1.0
- Your collateral can be seized instantly at liquidation
- Liquidators earn 5–10% penalty for executing liquidation
- Setting thresholds lower = fewer alerts but less reaction time
- Setting thresholds higher = more alerts but more time to act

### 3. Check Interval (Hours)

**Field:** `checkInterval`

How often the monitor runs automatically (in hours).

Default: `6` (checks every 6 hours)

Options: 1, 2, 3, 4, 6, 8, 12, 24

Example: Setting to `4` means checks run at 00:00, 04:00, 08:00, 12:00, 16:00, 20:00 UTC daily.

**Guidance:**
- **High leverage (HF 1.1–1.5):** Use 2–4 hours (closer monitoring)
- **Medium leverage (HF 1.5–2.0):** Use 6 hours (standard)
- **Low leverage (HF >2.0):** Use 12–24 hours (rare changes)

### 4. Notification Verbosity

**Field:** `verbosity`

Controls how often you get alerts.

- **`quiet` (default)**
  - Only sends alerts when HF drops below warning threshold
  - No messages if position is stable
  - Recommended for normal positions

- **`verbose`**
  - Sends daily summary even if position is stable (HF > 1.5)
  - Useful if you want to track your position trending
  - Recommended for very high leverage or active borrowing

- **`silent`**
  - No notifications at all (monitoring still runs)
  - Only useful if you check status manually with `/aave-monitor status`

### 5. Notification Channel

**Field:** `channel`

Where alerts are sent.

Options: `telegram` (default), `discord`, `slack`

**Important:** Make sure you have the channel already configured in OpenClaw before setting it here. If channel is not active, alerts will fail.

To check available channels:
```
/aave-config view channels
```

Example:
```json
{
  "channel": "telegram"
}
```

---

## Update Configuration: `/aave-config set`

Change individual settings without re-running init:

```bash
# Change wallet address
/aave-config set walletAddress 0xnewaddress...

# Change thresholds
/aave-config set thresholds critical=1.1 warning=1.25 stable=1.6

# Change check interval
/aave-config set checkInterval 4

# Change verbosity
/aave-config set verbosity verbose

# Change notification channel
/aave-config set channel discord
```

---

## View Configuration: `/aave-config view`

Display all current settings:

```
/aave-config view
→
Wallet Address: 0x1234...5678
Thresholds: Critical 1.05 | Warning 1.2 | Stable 1.5
Check Interval: 6 hours
Verbosity: quiet
Channel: telegram
Last Check: 2026-02-11 08:15 UTC
Last Status: STABLE (HF 2.31)
```

---

## Chain-Specific Configuration (Advanced)

By default, the monitor checks Ethereum mainnet. To monitor other chains or multiple chains:

### Single Chain Other Than Ethereum

Edit the skill config:

```json
{
  "chain": "polygon"
}
```

Supported chains:
- `ethereum` (default)
- `polygon`
- `arbitrum`
- `optimism`
- `base`
- `avalanche`

### Multiple Chains (Future Enhancement)

Currently, the skill monitors one chain at a time. To monitor multiple chains, you'll need separate cron jobs:

```bash
# Create separate jobs for each chain
/aave-monitor enable --chain polygon --interval 6 --label "Aave Monitor (Polygon)"
/aave-monitor enable --chain ethereum --interval 6 --label "Aave Monitor (Ethereum)"
```

---

## Threshold Recommendations by Leverage Level

| Leverage | HF Range | Recommended Thresholds | Check Interval |
|----------|----------|------------------------|-----------------|
| High | 1.05–1.3 | Critical: 1.05, Warning: 1.15 | 2–3 hours |
| Medium | 1.3–2.0 | Critical: 1.05, Warning: 1.2 | 6 hours |
| Low | 2.0+ | Critical: 1.05, Warning: 1.3 | 12 hours |

---

## Common Scenarios

### Scenario: Actively Trading with Borrowed Assets
- Thresholds: Critical 1.05, Warning 1.15
- Interval: 3 hours
- Verbosity: verbose (want daily position updates)
- Reason: Positions change rapidly; early warnings are critical

### Scenario: Long-Term Lender (Set & Forget)
- Thresholds: Critical 1.05, Warning 1.3
- Interval: 12 hours
- Verbosity: quiet (only alert on danger)
- Reason: Minimal changes; don't need frequent updates

### Scenario: Yield Farming on Borrowed Capital
- Thresholds: Critical 1.1, Warning 1.25
- Interval: 4 hours
- Verbosity: verbose (track APY + risk)
- Reason: Higher leverage; need tighter monitoring and position updates

---

## Troubleshooting Config

**Q: I set the wallet address but still see "Invalid wallet address"**

A: Check the format is exactly `0x` + 40 hex chars. No spaces, no mixed case issues.

Example of valid format:
```
0x1234567890abcdef1234567890abcdef12345678
```

**Q: I changed thresholds but alerts still trigger at old values**

A: The cron job uses the old config. Run:
```
/aave-monitor disable
/aave-monitor enable
```

This restarts the monitoring job with new thresholds.

**Q: Alerts go to Telegram but I want Discord**

A: Run:
```
/aave-config set channel discord
/aave-monitor disable
/aave-monitor enable
```

Then verify Discord channel is configured in OpenClaw.

**Q: I want to monitor multiple wallets or chains**

A: Create separate jobs with different labels:
```
/aave-monitor enable --wallet 0xfirstaddress --label "Main Account"
/aave-monitor enable --wallet 0xsecondaddress --label "Trading Account"
```

(Feature coming soon)

---

## Reset Configuration

To start fresh:

```bash
/aave-config reset
/aave-config init
```

This wipes all settings and asks you to re-enter them.



path: references/cron-integration.md
content: # Cron Integration Guide

This skill integrates with OpenClaw's cron scheduler to run monitoring checks automatically on a schedule you define.

## How It Works

When you run `/aave-monitor enable`, the skill:

1. **Reads your config** (wallet address, thresholds, interval, etc.)
2. **Creates a cron job** that runs every N hours
3. **Registers with OpenClaw's scheduler** for persistent, background execution
4. **Runs checks silently** in the background
5. **Sends alerts only when needed** (when HF drops below threshold)

## Commands

### Enable Monitoring

```bash
/aave-monitor enable [--interval N] [--chain ethereum]
```

Starts automatic monitoring. Options:
- `--interval N` — Check every N hours (default: from config, usually 6)
- `--chain ethereum` — Monitor specific chain (default: ethereum)

Example:
```bash
/aave-monitor enable --interval 4
```

### Check Status

```bash
/aave-monitor status
```

Shows:
- Current config
- Last check time and result
- Next scheduled check
- Last alert (if any)

Example output:
```
Wallet: 0x1234...5678
Chain: ethereum
Thresholds: Critical 1.05 | Warning 1.2
Interval: 6 hours
Next check: 2026-02-11 14:00 UTC
Last check: 2026-02-11 08:15 UTC (STABLE, HF: 2.31)
```

### Manual Check

```bash
/aave-monitor check
```

Runs a check immediately (doesn't affect the schedule):
```bash
/aave-monitor check --chain polygon
```

Returns:
```
Health Factor: 2.31 (Stable ✓)
Total Collateral: $50,342.12
Total Debt: $21,804.00
...
```

### Disable Monitoring

```bash
/aave-monitor disable
```

Stops the cron job. Can be re-enabled anytime.

### View History

```bash
/aave-monitor history [limit]
```

Shows last N checks (default: 5):

```
2026-02-11 08:15 UTC | STABLE | HF 2.31
2026-02-11 02:15 UTC | STABLE | HF 2.28
2026-02-10 20:15 UTC | STABLE | HF 2.35
```

## Cron Job Lifecycle

### Creation

When you enable monitoring:

```bash
/aave-monitor enable --interval 6
```

This creates a cron job internally with:
```json
{
  "name": "aave-monitor-check",
  "schedule": {
    "kind": "every",
    "everyMs": 21600000  // 6 hours in milliseconds
  },
  "payload": {
    "kind": "agentTurn",
    "message": "Check Aave position: 0x1234...5678 (eth) - if HF<1.2 alert, else silent"
  },
  "sessionTarget": "isolated",
  "enabled": true
}
```

### Execution

The scheduler runs the job at the specified interval. Each execution:

1. Calls the monitor script with your wallet address
2. Fetches latest health factor from Aave API
3. Compares to your thresholds
4. Sends alert (if needed) or remains silent
5. Updates last-check timestamp in config

### Logs

Check job execution logs:

```bash
/aave-monitor logs [limit]
```

Output:
```
2026-02-11 08:15:24 UTC | Health Factor: 2.31 (no alert needed)
2026-02-11 02:15:18 UTC | Health Factor: 2.28 (no alert needed)
2026-02-11 00:15:12 UTC | Health Factor: 1.18 ⚠️ WARNING ALERT SENT
```

### Deletion

When you disable monitoring:

```bash
/aave-monitor disable
```

The cron job is paused but not deleted. Re-enable it anytime with:

```bash
/aave-monitor enable
```

To permanently delete the job:

```bash
/aave-monitor disable --remove
```

## Scheduler Reliability

OpenClaw's cron scheduler:
- ✅ Persists across restarts
- ✅ Automatically retries failed checks
- ✅ Prevents duplicate runs (no overlap)
- ✅ Logs all executions with timestamps
- ✅ Supports concurrent jobs for multiple wallets/chains (future)

## Timezone Notes

All cron times are in **UTC** by default. Your alert timestamps are also in UTC.

Example: If you set `interval: 6`, checks happen at:
- 00:00 UTC
- 06:00 UTC
- 12:00 UTC
- 18:00 UTC

If you need a custom schedule, see "Advanced: Custom Schedules" below.

## Troubleshooting

### Cron Job Not Running

**Symptom:** `/aave-monitor status` shows "No checks scheduled" or old last-check time

**Solution:**
```bash
/aave-monitor disable
/aave-monitor enable
```

This recreates the cron job.

### Alerts Not Being Sent

**Symptom:** Health factor is low, but no alert received

**Causes & Solutions:**
1. Check if monitoring is enabled: `/aave-monitor status`
2. Check your channel config: Does Telegram/Discord/Slack have an active connection?
3. Run manual check: `/aave-monitor check` to verify API works
4. View logs: `/aave-monitor logs 10` to see if check ran

### Duplicate Alerts

**Symptom:** Getting the same alert multiple times

**Solution:** This shouldn't happen, but if it does:
```bash
/aave-monitor disable
/aave-monitor enable  # Recreates job with deduplication
```

### Interval Too Frequent or Too Long

**Change interval:**
```bash
/aave-config set checkInterval 4  # Every 4 hours
/aave-monitor disable
/aave-monitor enable  # Recreate with new interval
```

---

## Advanced: Custom Schedules

For non-standard schedules, you can create a custom cron job directly:

### Example: Check at Specific Times (5am, 1pm, 9pm UTC)

```bash
/cron add \
  --name "aave-monitor-custom" \
  --schedule "cron:0 5,13,21 * * *" \
  --payload agentTurn \
  --message "Run Aave monitor check for 0x1234...5678"
```

### Example: Check Every 4 Hours Starting at 2am UTC

```bash
/cron add \
  --name "aave-monitor-every4" \
  --schedule "every:14400000" \
  --payload agentTurn \
  --message "Run Aave monitor check" \
  --anchorMs 1707555600000  # 2026-02-10 02:00 UTC
```

See `/cron help` for full cron syntax options.

---

## Performance Impact

Each check uses minimal resources:
- **Network:** 1 HTTP request to Aave API (~50 KB)
- **CPU:** <100ms processing per check
- **Memory:** <10 MB temporary
- **Storage:** ~1 KB per check result logged

Running checks every 6 hours:
- **Monthly API calls:** 120
- **Monthly data:** ~6 MB
- **Cost:** Free (Aave API is public, no API key needed)

---

## Integration with Other OpenClaw Features

### Combine with `/cron` for Advanced Scheduling

Create multiple monitoring jobs with different thresholds:

```bash
# Conservative monitoring (daily summary)
/aave-monitor enable --interval 24 --label "Daily Summary"

# Aggressive monitoring (every 2 hours)
/aave-monitor enable --interval 2 --label "Active Trading"
```

### Combine with Message Routing

Alerts are automatically routed to your configured channel (Telegram, Discord, etc.) based on skill config.

### Combine with Session History

All checks are logged to OpenClaw session history:

```bash
/sessions history [limit]
```

Includes alert messages and check results for audit trail.

---

## Best Practices

1. **Start with 6-hour interval**, adjust based on your leverage level
2. **Test with `/aave-monitor check`** before enabling automated monitoring
3. **Monitor logs** the first few days to ensure correct behavior
4. **Adjust thresholds** based on your risk tolerance, not market conditions
5. **Keep wallet address updated** if you use different addresses for different pools

---

## Monitoring Multiple Wallets (Future)

Currently, you can only monitor one wallet per OpenClaw instance. For multiple wallets:

**Option 1:** Spawn a separate sub-agent session for each wallet
```bash
/sessions spawn --agentId main --label "Monitor Wallet 2" \
  --task "Enable Aave monitoring for 0xanotheraddress"
```

**Option 2:** Use multiple OpenClaw instances with separate configs

This will be simplified in a future release with built-in multi-wallet support.
