Add Multiple Security Rule Checks for DeFi Projects #2389

Over the past year, I've developed several security rule checks specifically designed for DeFi projects, and I believe these will greatly enhance Slither's capabilities in identifying potential security risks within smart contracts. This contribution includes a variety of checks, such as:

  1. AMM k-Value Error Check: Validates the correctness of the k-value within AMM contracts to prevent manipulation or unintended behavior.
  2. Price Manipulation Check: Identifies potential vectors for price manipulation within DeFi protocols, ensuring integrity in pricing mechanisms.
  3. DeFi Behavior Nesting Check: Detects complex nesting of DeFi behaviors that could lead to unforeseen vulnerabilities or centralization risks.
  4. Centralization Risk Check: Highlights areas within the contract code that may introduce centralization, which is contrary to the fundamental principles of DeFi.
  5. Front-Running Vulnerability Check: Aims to uncover potential vulnerabilities that could allow for front-running attacks, protecting users from exploitation.

In addition to the rule checks, I have included comprehensive test cases for each to facilitate thorough evaluation and integration.

I understand that these contributions may require extensive discussion, possible code optimization, and additional descriptive documentation. I'm fully prepared to engage in these discussions and make necessary adjustments. Furthermore, I have compiled a set of summary documents and thought processes behind these rule developments, which I'm happy to share upon request. These documents could provide valuable insights into the rationale and methodology of the rule checks.

This effort aligns with the ongoing initiative to open-source more rules as part of the MetaTrustLabs Falcon project, and I believe it would be beneficial to include these checks in Slither as part of a collaborative push towards enhancing smart contract security.

Looking forward to your feedback and the opportunity to discuss these contributions further.

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-tests 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 tests 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 tests.
    • @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.

CodeRabbit Commands (invoked as PR comments)

  • @coderabbitai pause to pause the reviews on a PR.
  • @coderabbitai resume to resume the paused reviews.
  • @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
  • @coderabbitai resolve resolve all the CodeRabbit review comments.
  • @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

  • You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
  • The JSON schema for the configuration file is available here.
  • If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/coderabbit-overrides.v2.json

Hey, we'd like to upstream high quality detectors and any improvements in the false positive rate but it is a bit difficult to review such large PR's. Would you please curate detectors you'd like to upstream and provide the motivation with examples (similar to what we'd include in the wiki?
