Spot price detector

[talfao]

Hello everyone,

This detector is continuing the work of my thesis for possible vulnerabilities regarding the utilization of oracles in smart contracts. (related to another PR #2289).

A detector is named an oracle spot price detector (oracle-spot-price). It checks the following methods for indicating spot price data in connection with Uniswap Liquidity pools:

• getReserves
• slot0
• balanceOf pattern -> certain patterns could indicate a functionality to obtain price data.

Then it detects arithmetic operations or functions which could indicate a spot price calculation.

I am looking forward to any feedback and am willing to improve the code based on it.

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.
