-When compiling your program, it is important to set the `CAIRO_PATH` environment variable to the path of the `eth-essentials` directory. This is necessary for the compiler to find the imported functions. For the example above, this would look like this: `cairo-compile --cairo_path="packages/eth-essentials" ...`
