WHAT

Allow string type in link creation

WHY

It is impossible to send some token amounts, especially if the decimal = 18

For example, I want to send 370637.59981187013726614 MEOW tokens, since this is valid amount with 18 decimals. However, SDK forces me to send number type. It is impossible to represent this string amount in terms of number.

HOW

Added util called getStringAmount, which either accepts number or string. If the accepted type is number, it behaves as before to make it backward compatible. If the input is string (which is also now supported by modifying IPeanutLinkDetails), the input amount is accepted as it is.

Summary by CodeRabbit

  • New Features

    • Enhanced tokenAmount property to accept both numeric and string values for greater flexibility.
    • Introduced a new function to improve handling of tokenAmount, ensuring robust input processing across multiple functions.
  • Bug Fixes

    • Improved error handling to prevent issues with type mismatches in transaction processes, increasing reliability during token amount validation and preparation.

Walkthrough

Walkthrough

The recent changes enhance the IPeanutLinkDetails interface by allowing the tokenAmount property to accept both numeric and string types. Additionally, a new function, getStringAmount, improves the handling of token amounts in multiple functions, ensuring robust input processing and reducing the risk of type mismatches. These adjustments enhance the flexibility and reliability of token amount management throughout the codebase.

Changes

Files Change Summary
src/consts/interfaces.consts.ts Updated tokenAmount type in IPeanutLinkDetails from number to `number
src/index.ts Introduced getStringAmount function to improve token amount processing in prepareDepositTxs and validateLinkDetails. Replaced calls to trim_decimal_overflow with getStringAmount.
src/raffle.ts Updated prepareRaffleDepositTxs to use getStringAmount for token amounts, enhancing accuracy in conversion.

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.
