What is Contract Scanner?
The Contract Scanner is a professional-grade security extension designed to safeguard blockchain interactions. By integrating with Openclaw Skills, this tool provides developers and traders with a robust framework to perform deep analysis on smart contracts before committing capital. It focuses on identifying malicious logic like honeypots, exorbitant buy/sell taxes, and centralized ownership risks that could lead to rug pulls.
In the fast-moving world of decentralized finance, having an automated auditor within your Openclaw Skills library is essential. This skill bridges the gap between complex source code and actionable security intelligence, providing users with a clear risk assessment in seconds.
Contract Scanner Use Cases
- Verifying the safety of a new token before trading on decentralized exchanges.
- Auditing tax mechanisms to ensure transparency in transaction fees and avoid hidden costs.
- Checking contract ownership status to detect if developers can manipulate funds or pause trading.
- Scaling security checks via API for high-frequency trading bots or portfolio trackers.
How Contract Scanner Works
- The user provides a smart contract address through the Openclaw Skills interface.
- The system fetches the contract source code and on-chain metadata via the Etherscan API.
- A local Python-based analysis engine parses the code for known vulnerability patterns and malicious logic.
- The skill calculates a comprehensive risk score based on liquidity, taxes, and ownership flags.
- A formatted report is generated, categorizing the contract from Low to Critical risk.
Contract Scanner Setup
To activate the Contract Scanner within your Openclaw Skills environment, ensure you have an Etherscan API key and the necessary binaries installed.
# Set your environment variable
export ETHERSCAN_API_KEY="your_api_key_here"
# Verify dependencies
python3 --version
curl --version
