Walkthrough

## Walkthrough The updates enhance the `getPools` function by introducing a new `Pair` type for improved type safety and data structure clarity. The integration of a multicall contract optimizes interactions by aggregating multiple calls, thus reducing transaction overhead. Additionally, enhanced error handling mechanisms have been implemented, ensuring robustness in data retrieval. The return value is now formatted for better consistency, while a new JSON file defines the `aggregate` function in the `IMulticall3` contract, optimizing efficiency in decentralized applications. ## Changes | Files | Change Summary | |-----------------------------------------|-----------------------------------------------------------------------------------------------------| | `packages/client/src/getPools.ts` | - Added new `Pair` type for structured pool pairs.
- Updated `getPools` function for better type safety and efficiency using multicall.
- Enhanced error handling with data validity checks.
- Changed return value to `formattedPools`. | | `packages/client/src/multicall3.json` | - Introduced JSON definition for `IMulticall3` contract's `aggregate` function for batching calls. | ## Sequence Diagram(s) ```mermaid sequenceDiagram participant User participant getPools participant multicallContract participant systemContract participant uniswapInterface User->>getPools: Request pool data getPools->>multicallContract: Aggregate calls for unique pairs multicallContract->>systemContract: Fetch pairs data systemContract-->>multicallContract: Return pairs data multicallContract-->>getPools: Return aggregated data getPools->>uniswapInterface: Decode token addresses and reserves getPools-->>User: Return formatted pools data ```

Tips

### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `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. ### 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 an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configuration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - 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/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
