Tap a contract → the wallet popup appears → look for a red warning. Nothing is ever sent on-chain; every test expires by itself in 10 minutes and authorizes 0.01 DAI at most.
How to test
Connect (MetaMask, Ethereum mainnet).
For each row press Sign test — you can press Reject in the wallet, the warning (or its absence) shows either way. Look at the popup's color/banner only.
Mark the row: Green = no warning, Red = "untrusted / phishing" style warning, Other = anything unusual.
Press Copy results at the end and send the text back.
