RSKj Precompile to get transaction refunds

Prize Bounty

0.02570 RBTC

(approximately 1600 USD at time of posting)

Challenge Description

Implement RSKIP139: Precompile to get transactions refunds

Classes to look for examples: package co.rsk.pcc Implement unit tests to verify proper function of the precompiled contract, ExtCodeHashTest >> testDoEXTCODEHASHWithoutArguments() can be used as reference to create these tests.

This is expected to be a simple change to the implementation of RSKj. However it is a change to consensus nonetheless, thus the focus will be on identifying various consensus-related scenarios and creating explicit tests for them.

Submission Requirements

The submission is expected to be:

A Github pull request on the RSKj repository
Implement the features as described in the “challenge description” section
Add tests that provide coverage for the new features added

Judging Criteria

Only one submission allowed per participant. Where a participant wishes to resubmit, update the original submission instead of submitting a separate entry.
If the submission involves a graphical user interface of any variety, please include a video recording of it in action.
If the submission involves a command line interface of any variety, please include a text file of it in action (including outputs).
Test coverage for any implementation is viewed favourably: More test coverage is better.
In cases where the bounty requires a Github PR on an existing repo, and that repo has continuous integration (CI) set up, the PR should not fail on the CI steps.
Documentation is viewed favourably: Include specific instructions on how to set up and use your submission. Optionally, include any explanations of architectural/ design choices that went into the submission.
The easier it is for the reviewer to run and understand the submission, the better, so be sure to consider this in your submissions!
