Contract verification

The process of matching published source code and compiler settings to a deployed contract’s bytecode.

PLAIN-ENGLISH DEFINITION

In more detail

Verification helps you see the code behind a contract address instead of only its bytecode. Explorers can display readable functions and let others reproduce the compilation match. A verified badge is a transparency signal, not a security certificate: the matched code may still contain bugs, risky permissions or intentionally harmful behavior.

How you might use it

Before interacting, you check the verified source and discover that an administrator can change a fee, which the app’s homepage never mentioned.

Published source and compiler settings feed a compilation cube; matching compiled and deployed bytecode panels explain contract verification while the subtitle states that source matching is not a security certificate.
