# Contract Security Check

> Verify smart contract security and analyze contract code

Ranger helps you verify the security of Robinhood Chain smart contracts by analyzing verified contract source code from Blockscout. Get comprehensive security assessments and understand contract functionality.

## What Gets Analyzed

When you request a security check, Ranger examines:

* **Common Vulnerabilities** - Reentrancy, overflow, access control issues
* **Suspicious Functions** - Hidden minting, ownership changes, fee manipulation
* **Proxy Contract Risks** - Proxy patterns and upgrade risks
* **Centralization Risks** - Owner privileges and control mechanisms
* **Rug Pull Indicators** - Warning signs of potential scams

## How to Use

Ask about contract security using the contract address:

```
Check the security of 0x020bfc650a365f8bb26819deaabf3e21291018b4
Is this contract safe?
Analyze this contract address for vulnerabilities
```

## Security Analysis Types

### Full Security Check

Request a comprehensive security analysis:

```
Check the security of [contract address]
```

This provides a detailed assessment of potential risks and vulnerabilities.

### Contract Explanation

Understand how a contract works:

```
Explain this contract address
What does this contract do?
```

This explains the contract's functionality, main functions, and security considerations.

## Special Cases

### Launchpad Tokens

Ranger reads a token's launchpad directly from GMGN (noxa, flap, bankr, virtuals). A standardized launchpad template limits — but does not eliminate — rug risk, so Ranger still reports the security flags. Ranger never infers a launchpad from a contract address suffix.

### Unverified Contracts

If a contract is not verified on Blockscout, Ranger will inform you and recommend verifying the contract before trusting it.

## Understanding Results

Security assessments include:

* **Risk Level** - Overall security assessment
* **Specific Issues** - Detailed list of potential vulnerabilities
* **Recommendations** - Suggestions for safer alternatives or precautions
* **Contract Functionality** - Explanation of what the contract does

<Warning>
  Security analysis is based on verified source code. Always do your own research (DYOR) and never invest more than you can afford to lose.
</Warning>

## Data Source

Contract analysis uses verified source code from **Blockscout**, the official Robinhood Chain block explorer. Only verified contracts can be fully analyzed.

## Tips

* Always verify the contract address before checking
* Use full contract addresses (0x followed by 40 characters)
* Ask follow-up questions if you need clarification on specific functions
