🛡️ Contract Scanner - 合约安全检测
Scan smart contracts for security risks and scams.
Features
- 🔍 Honeypot detection
- 💸 Tax analysis (buy/sell)
- 🔐 Ownership check
- 📊 Risk scoring
- ⚠️ Real-time alerts
Usage
# Scan a contract
/contract-scanner check 0x123...abc
# Check tax
/contract-scanner tax 0x123...abc
# Verify ownership
/contract-scanner owner 0x123...abc
Risk Levels
- 🟢 Low - Safe to trade
- 🟡 Medium - Some risks, be careful
- 🟠 High - High risk, avoid
- 🔴 Critical - Scam/honeypot, DO NOT BUY
Usage Guidance
This package appears to be a stub or an overpromising toy rather than a working contract scanner. Before installing or providing any API keys: 1) Ask the author for the source/origin and why ETHERSCAN_API_KEY and curl are required. 2) Request a version that actually calls the declared APIs (examples of network calls that use your key) or remove the requirement. 3) Only supply an API key in a sandboxed environment or use a limited/test key until you verify behavior. 4) If you need real scanning, prefer tools with verifiable provenance and documented integrations (e.g., public GitHub repo, known scanners). 5) If you plan to run the included script, inspect it locally first — it currently only prints simulated results and does not exfiltrate data, but the mismatch between claims and code is a risk sign.
Capability Analysis
Type: OpenClaw Skill
Name: contract-scanner
Version: 1.0.0
The skill bundle is a placeholder for a smart contract security scanner. The Python script (scanner.py) currently contains only mock data and does not perform any actual network requests or sensitive operations, despite importing urllib.request and requesting an ETHERSCAN_API_KEY in the metadata. There is no evidence of data exfiltration, malicious execution, or prompt injection.
Capability Assessment
Purpose & Capability
The skill's stated purpose is contract scanning using services like Etherscan/TokenSniffer, but the shipped implementation (scanner.py) only prints simulated, hard-coded results and does not call any blockchain APIs or analyzers. The registry metadata requires ETHERSCAN_API_KEY and lists curl, but neither is used by the provided code. The SKILL.md also advertises features (real-time alerts, API access, deep analysis) that are not implemented in the code bundle.
Instruction Scope
SKILL.md gives usage/command examples and declares required env/binaries, but the runtime instructions do not describe any network/API usage or data flows. The instructions are high-level and do not show how an ETHERSCAN_API_KEY would be used, nor do they instruct reading user files or other sensitive data. However, the combination of vague instructions and a non-functional scanner implementation is a red flag.
Install Mechanism
There is no install spec (instruction-only pattern) and no external archives are downloaded. Only a single Python file is included. This is the lower-risk install pattern, but note the file content does not match the claimed behavior.
Credentials
The skill requires ETHERSCAN_API_KEY (a sensitive credential) and lists curl in required binaries, yet the included Python script does not read environment variables, invoke curl, or perform network queries. Requesting a sensitive API key without using it is disproportionate and suspicious because it offers no clear justification for needing that secret.
Persistence & Privilege
The skill is not always-enabled, does not request persistent system-wide changes, and contains no install-time behavior that would grant it ongoing privileges. There is no evidence it modifies other skills or system config.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install contract-scanner - After installation, invoke the skill by name or use
/contract-scanner - Provide required inputs per the skill's parameter spec and get structured output
