🪧 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>, please review it.
  • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @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.

[error] 488-488: Use Number.parseInt instead of the equivalent global.

ES2015 moved some globals into the Number namespace for consistency.
Safe fix: Use Number.parseInt instead.

416-419: 逻辑清晰，操作安全。
代码在这里看起来简洁明了，没有发现明显问题。

423-437: fallback 方案设计良好。
当原生方法不可用时，使用 fallback 能有效提高鲁棒性。日志信息也能帮助排查问题。

packages/kit-bg/src/vaults/impls/evm/sdkEvm/ClientEvm.ts (1)

31-34: 逻辑简化，易读性增强。
现在只检查 baseFeePerGas 是否为 0 或 NaN，整体流程更直观清晰。
