Require message
Trigger a failed condition and jump back to its source line.
Solidity 0.8.36REPL modeExpected error
Why use this example
Use this pattern to reproduce a failure or follow an execution from Solidity source into calls and EVM opcodes. The entry isolates require message so its input, result, and state changes stay easy to compare.
Solidity to run
uint256 balance = 3
require(balance >= 10, "balance too low")What to expect
The failed condition returns the “balance too low” reason and identifies the source line that triggered it.
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.
