Fuzz Testing

Fuzz the inputs, particularly for precompiles and asset amounts (for decimal conversion). Should give us confidence that number inputs function properly in various settings and at the interface between the EVM and Cosmos SDK.

Start by locating the Go entry points for precompiles, asset-amount decimal conversion, and the EVM–Cosmos SDK boundary. Define fuzz cases for number inputs across those interfaces and verify that the fuzzing runs complete without conversion or execution failures.
