Funding Rate Scanner

Scan crypto funding rates and find arbitrage opportunities. No API key needed.

Security Scan

The skill's code and instructions match its stated purpose (scanning Binance Futures funding rates) and it does not request credentials or perform unexpected file/network access.

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.

Assessment

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.

Output Example

=== Funding Rate Opportunities ===

Rank  Coin    Rate      Annual(5x)  Volume
1     DUSK    -0.38%    2071%       $30M

Strategy

Negative funding rate = shorts pay longs every 8 hours.

1. Open long position on high negative rate coin
2. Collect funding every 8 hours (3x daily)
3. Set stop-loss to limit downside
4. 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
