[Project Milestones] What are the key milestones you need to achieve in order to complete your project successfully?

Milestone 1: Enhancing Repository Collaboration

Review, fix, and merge PRs from the official repository

There are a number of outstanding PRs on the official lucid repo that have not been reviewed or merged because the repository is no longer maintained. We have been updating and maintaining our own public fork for sometime now. On our fork, we have reviewed and merged a number of PRs from both ourselves and external contributors; however, there is a backlog of PRs on the main repository that we did not have capacity for. For this milestone, we will review, fix and merge outstanding PRs from the main lucid repository to our maintained fork.

Deliverables:

• List of Outstanding PRs: Compile a comprehensive list of all outstanding Pull Requests (PRs) on the official Lucid repository that have not been reviewed or merged.

• Evaluation and Fixing: Assess the code changes proposed in each PR and identify any issues, conflicts, or improvements needed.

• Updated Fork: Apply necessary fixes to ensure compatibility with the maintained fork and resolve any conflicts that may arise during the merging process.

• Merged PRs: Actively review, test, and merge the identified PRs from the main Lucid repository into the maintained fork.

>Milestone 2: Augmenting Lucid's Utility Library Functions

Expand Lucid’s utility library with additional functions

Lucid is one of the most widely used off-chain frameworks in the ecosystem; however, due to lack of active development it is missing a number of utility and convenience functions. For instance, a common design pattern is to pass the index of an input, output or reference input in the transaction redeemer. Currently, to do this for an input in Lucid requires a lot of boilerplate, first sorting the inputs by their TxOutRef’s and then indexing them and then doing a first pass of balancing to determine if any change inputs need to be introduced which would require another pass over the inputs to reassign correct indices. This milestone covers the implementation and testing of such utility functions to Lucid.

Deliverables:

• Identification of Missing Functions: Conduct a comprehensive analysis of the Lucid framework to identify gaps in utility and convenience functions that hinder efficient development.]

• Function Design: Develop a design proposal outlining the new utility functions to be implemented, with a focus on simplifying common design patterns, such as passing indices in the transaction redeemer.

• Implementation: Code and integrate the proposed utility functions into the Lucid framework to streamline tasks like sorting inputs by TxOutRef's, indexing, and balancing.

• Testing Suite: Develop a robust testing suite to ensure the functionality, correctness, and efficiency of the newly implemented utility functions.
