Description

The main objective of bank is to condense and streamline the role of the bank module. Currently it handles a multitude of jobs such as handle sends, handle account restrictions, handle delegation counting, minting and burning of coins, we want to streamline this.

Within the ADR we cover ways to achieve this with pros and cons.

We would like to add more implementation details in the next coming days and more importantly obtain feedback

Reference: #17579

Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

In addition to the above, the bank module is currently too rigid and handles too many tasks, so this proposal aims to streamline the module by focusing on core functions `Send`, `Mint`, and `Burn`.

Currently, the module is split accross different keepers with scattered and duplicates functionalities (with 4 send functions for instance).
