ARC20_leo

About The Project

Implementation of the 6 mandatory rules in Leo Programming Language so that they can be invoked in a Smart contract.

They are: balance_of, total_supply, approve, transfer_from, transfer, and allowance.

To run name function:

Input file ARC20_leo/inputs/arc20_leo.in

[name]
is_dummmy: u64 = 0u64;

leo run name

Console output.

 • Executing 'arc20_leo.aleo/name'...
 • Executed 'name' (in 6431 ms)

➡️  Outputs

 • 65u64

To run Test functions:

In every ARC20 function the input values are declared in \input\arc20_leo.in Each Test function uses the algorithm of the original function and compares its output with the values coded into the test function. In case the comparison is successful, the Test function will return True in a boolean variable.
