Description
Scan crypto funding rates and find arbitrage opportunities. No API key needed.
README (SKILL.md)
Funding Rate Scanner
Scan all crypto perpetual futures funding rates and find high-yield arbitrage opportunities.
Features
- Scan 500+ coins on Binance Futures
- Find extreme negative funding rates (earn by going long)
- Calculate annualized returns at different leverage levels
- Track rate changes over time
Usage
# Scan top opportunities
node scripts/scan.js
# Monitor specific coins
node scripts/monitor.js DUSK DASH AXS
# Get detailed analysis
node scripts/analyze.js DUSK
Output Example
=== Funding Rate Opportunities ===
Rank Coin Rate Annual(5x) Volume
1 DUSK -0.38% 2071% $30M
2 AXS -0.12% 655% $46M
3 DASH -0.12% 649% $50M
Next settlement: 03:00 UTC (2h away)
Strategy
Negative funding rate = shorts pay longs every 8 hours.
- Open long position on high negative rate coin
- Collect funding every 8 hours (3x daily)
- Set stop-loss to limit downside
- Profit from both rate + potential price appreciation
Risk Warning
- High leverage = high risk
- Rates can change
- Always use stop-loss
- Only risk what you can afford to lose
Usage Guidance
This skill appears to do what it says: it queries public Binance Futures endpoints and prints funding-rate stats. Before installing: ensure you have Node.js available (the scripts are run with 'node' though the skill metadata didn't list it), verify the package source/repository if you care about provenance (package.json points to a GitHub repo), and run the scripts in a controlled environment if you want to inspect behavior. It doesn't request API keys or secrets — do not provide exchange API keys unless you add features that legitimately require them. Finally, remember this is a trading tool: it contains no safeguards and trading with leverage carries financial risk, not a security issue but an operational one.
Capability Analysis
Type: OpenClaw Skill
Name: funding-rate-scanner
Version: 1.0.2
The OpenClaw AgentSkills skill bundle is benign. It provides scripts to scan, monitor, and analyze cryptocurrency funding rates from the Binance Futures public API (fapi.binance.com). All network requests are directed to legitimate Binance endpoints, and there is no evidence of data exfiltration, malicious execution, persistence mechanisms, or prompt injection attempts against the AI agent in SKILL.md. The scripts use standard Node.js modules and process user input for coin symbols without introducing exploitable vulnerabilities for malicious purposes.
Capability Assessment
Purpose & Capability
The name/description (funding-rate scanning, arbitrage) align with the included code which queries Binance Futures public market endpoints and computes annualized rates. Minor mismatch: the SKILL.md shows running Node scripts but the registry metadata lists no required binaries — the skill effectively requires a Node.js runtime even though 'required binaries' is empty.
Instruction Scope
SKILL.md only instructs running the included node scripts. The scripts only perform HTTPS GET requests to Binance public APIs and print calculations — they do not read local files, access environment variables, or transmit data to third-party endpoints beyond Binance.
Install Mechanism
There is no install spec (instruction-only), which minimizes install-time risk. The package includes package.json and JS scripts but no external downloads or npm dependencies; the only runtime requirement is Node.js, which the skill did not declare in registry 'required binaries'.
Credentials
The skill requests no environment variables, secrets, or config paths. All network calls go to Binance public REST endpoints; there are no credential requests or hidden endpoints.
Persistence & Privilege
always:false and default invocation settings are used. The skill does not modify other skills or system configs and does not request persistent privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install funding-rate-scanner - After installation, invoke the skill by name or use
/funding-rate-scanner - Provide required inputs per the skill's parameter spec and get structured output
