Label an address

Give an address a readable label while testing named actors.

Solidity 0.8.36REPL mode

Why use this example

Use this pattern to shape local EVM state directly while keeping the setup and its visible effect in the same investigation. The entry isolates label an address so its input, result, and state changes stay easy to compare.

Solidity to run

address treasury = address(0xBEEF)
vm.label(treasury, "Treasury")
treasury

What to expect

The treasury address remains the returned Solidity value while the local VM records its readable label.

Continue the investigation

Change a value, add another expression, or open Inspect after the run. Accepted entries remain available to the next entry, and the clean replay keeps the complete result reproducible.
