Analyze smart contracts with GPT-4o to get instant risk scores and plain-English security reports
ChainRaven's AI Contract Analyzer uses GPT-4o to automatically review smart contract source code and deliver a comprehensive risk assessment in plain English. It's the fastest way to understand what a contract does, who controls it, and what risks it may carry — before you interact with it or add it to your watchlist.
Required: The contract must have verified source code on its block explorer. Unverified or bytecode-only contracts cannot be analyzed.
Navigate to Analyze in the top navigation bar, or click the AI Analysis banner from your dashboard. You can analyze any contract address — it does not need to be on your watchlist.
Each report contains five structured sections:
A plain-English summary of what the contract does — whether it's a token, a lending protocol, a DEX, an NFT collection, or something else. This helps you quickly understand the contract's role before diving into technical details.
A breakdown of the contract's most important functions: what they do, who can call them, and what state they modify. Pay close attention to any functions that can move funds or change critical protocol settings.
Who controls the contract and how. This section identifies:
AccessControl roles (e.g., MINTER_ROLE, PAUSER_ROLE)Centralized access control is one of the most common risk vectors in DeFi. Contracts where a single address can pause, upgrade, or drain the protocol carry significant trust assumptions.
A list of identified risk factors, each with a plain-English explanation:
| Risk Factor | What It Means |
|---|---|
| Upgradeable proxy | Contract logic can be silently replaced by the admin |
| Centralized ownership | A single address controls all critical functions |
| Mint authority | New tokens can be created by privileged addresses |
| Pause mechanism | The contract can be frozen, blocking user withdrawals |
| Fee manipulation | Fee parameters can be changed arbitrarily |
| Missing reentrancy guard | Potential vulnerability to reentrancy exploits |
| Unchecked external calls | Calls to external contracts without error handling |
For ERC-20 and similar token contracts: supply mechanics, inflation/deflation mechanisms, transfer fees, blacklists, and transfer limits.
Every analysis produces a Risk Score from 0 to 100:
| Score | Level | What It Means |
|---|---|---|
| 0–30 | 🟢 Healthy | Low risk profile, standard patterns |
| 31–70 | 🟡 Elevated | Notable risk factors present — review carefully |
| 71–100 | 🔴 Critical | High-risk factors identified — proceed with caution |
Important: The risk score is a heuristic based on identified patterns — it's a starting point for due diligence, not a security guarantee. A score of 0 does not mean the contract is safe. Always review the full report before making decisions.
