Understand smart contracts before you sign.
SemaFy converts complex smart contract logic into clear, human-readable explanations; so you know exactly what permissions you're granting.
Works with Ethereum, Polygon, and other EVM-compatible chains
How it works
Three steps to understanding
Paste contract address
Enter any EVM-compatible contract address to begin analysis.
SemaFy analyzes permissions
We examine the contract's functions, permissions, and potential risk surfaces using deterministic analysis and AI explanation.
Get a clear explanation
Receive a human-readable breakdown of what the contract does and what permissions it requires, before you interact.
Why SemaFy
Built for informed decisions, not fear
Transparency
See exactly what a contract does in plain language. No hidden complexity, no technical jargon to decode.
Deterministic + AI
Our analysis combines deterministic code inspection with AI-powered explanations for comprehensive clarity.
Built for clarity
We present information neutrally, by helping you understand, not telling you what to do.
