A source match helps inspection but does not certify safe behavior.
LET’S PICTURE IT
Matching a printed recipe to a machine’s program helps you inspect it. It does not prove the recipe makes a healthy meal.
SEE IT FOR YOURSELF
A valid counter call, step by stepStep 1 / 4
This example begins with count zero and a request to call increment(). No real contract is deployed.
This example begins with count zero and a request to call increment(). No real contract is deployed.Execution follows the code’s input and permission rules. A website button is not the access-control mechanism.The function reads zero, calculates zero plus one, and writes one to persistent storage.The accepted state contains count one. Later reads can inspect it. Events are emitted only if the code implements them.

Verification is a build comparison
Source-verification services generally try to connect supplied source, compiler settings and dependencies with deployed bytecode. The precise match category and treatment of metadata or constructor data depend on the verifier.
Matching is useful evidence
A match lets readers inspect a human-readable implementation rather than infer everything from raw bytes. It can make permissions, interfaces and dependencies easier to understand. That is valuable even though it is not a security audit.
An upgradeable address needs more context
A proxy can delegate to implementation code stored elsewhere. Inspecting only the proxy’s small source can miss the logic currently used. Upgrade permissions and storage behavior also matter.
Avoid turning a badge into a guarantee
Verified source can still contain bugs, unsafe rules or malicious functionality. Identify the network, address, relevant implementation and actual match information before treating it as evidence about a specific deployment.
QUICK CHECK · NO PRESSURE
Does a verified-source badge guarantee that a contract has no bugs?
Source matching and safety analysis are different kinds of evidence.
