Every time an Ethereum transaction fails, it's extremely hard to trace down the troublemaking
line of code. The only hint you'll get is a generic error.

<Code light>Error: VM Exception while processing transaction: rever</Code>
</Breakout>
<List>
<Item>
<Copy dark>
<Gamma as="h3">No location</Gamma>

The error basically says "anything could have gone wrong here", which keeps you
completely in the dark about its exact location.

Working with a large code-base that contains hundreds of smart contracts, finding
the failing line of code quickly becomes a daunting task.

Sol-trace will give you full stack traces, including contract names, line numbers and code
snippets, every time you encounter an error.
