Purpose / Abstract

  • Removes the unused EVM PostProcessing hooks

Originally, the EVM post processing hooks were meant to allow EVM to talk to native Cosmos modules, but we are using precompiles for that now.

Summary by CodeRabbit

  • New Features

    • Enabled ERC20 token transfers to "nibi" accounts as regular Ethereum transactions.
  • Refactor

    • Simplified EVM transaction processing by removing unnecessary post-processing hooks.

Walkthrough

This update introduces a precompile to the Ethereum Virtual Machine (EVM) within the Nibiru blockchain, enabling ERC20 token transfers to "nibi" accounts via regular Ethereum transactions. Additionally, it removes redundant post-processing hooks from the EVM to streamline transaction handling. These changes aim to enhance functionality and improve code maintainability by eliminating unnecessary dependencies.

Changes

File(s) Change Summary
CHANGELOG.md Documented the addition of ERC20 transfer precompile and removal of EVM post-processing hooks.
x/evm/deps.go Removed references to gethcore and gethcoretypes, and the EvmHooks interface.

Poem

In the world of blockchain bright,
Transfers swift as rays of light.
From Ethereum’s vast domain,
To Nibiru where tokens reign.
Simplified, refined, now grand,
EVM flows at our command.

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.
    • @coderabbitai help me debug CodeRabbit configuration file.

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.
