🧹 Nitpick comments (11)
packages/plugin-cronos/src/constants/chains.ts (1)
11-18: Consider adding fallback RPC URLsUsing the same URL for both default and public configurations creates a single point of failure. Consider adding alternative RPC endpoints for redundancy.
rpcUrls: { default: { - http: ["https://evm.cronos.org/"], + http: [ + "https://evm.cronos.org/", + "https://cronos-evm.publicnode.com", + ], }, public: { - http: ["https://evm.cronos.org/"], + http: [ + "https://evm.cronos.org/", + "https://cronos-evm.publicnode.com", + ], }, },Also applies to: 36-43
packages/plugin-cronos/src/templates/index.ts (1)
1-31: Add important transaction details to transfer templateThe template should guide users about:
- Expected gas fees
- Transaction confirmation times
- What to do if transaction fails
Remember: - The chain name must be exactly "cronos" or "cronosTestnet" - The amount should be a string representing the number without any currency symbol - The recipient address must be a valid Ethereum address starting with "0x" +- Transaction requires gas fees in CRO +- Typical confirmation time is 5-6 seconds +- If transaction fails, check gas price and balancepackages/plugin-cronos/package.json (2)
2-7: Consider adding package metadata.Add description, keywords, repository, and license fields to improve package discoverability and provide essential metadata.
{ "name": "@elizaos/plugin-cronos", "version": "0.0.1", "type": "module", + "description": "Cronos blockchain plugin for Eliza framework", + "keywords": ["cronos", "blockchain", "eliza", "evm"], + "repository": { + "type": "git", + "url": "https://github.com/elizaOS/eliza.git" + }, + "license": "MIT", "main": "dist/index.js",
22-22: Enhance build configuration.The current build setup is minimal. Consider adding clean, watch, and type-check scripts.
"scripts": { - "build": "tsup --format esm --dts" + "clean": "rm -rf dist", + "build": "tsup --format esm --dts", + "build:watch": "tsup --format esm --dts --watch", + "type-check": "tsc --noEmit" },packages/plugin-cronos/README.md (3)
9-10: Use markdown links for URLs.Replace bare URLs with proper markdown links for better readability.
- - RPC Endpoint: https://evm.cronos.org/ - - Explorer: https://explorer.cronos.org/ + - RPC Endpoint: [https://evm.cronos.org/](https://evm.cronos.org/) + - Explorer: [https://explorer.cronos.org/](https://explorer.cronos.org/)Also applies to: 15-16

72-74: Sanitize error messages before throwing exceptionsWhen catching errors, avoid directly including
error.messagein thrown errors. Provide user-friendly messages to prevent potential leakage of sensitive information.
140-148: Provide generic error messages to callbacksReturning raw error messages to users can expose sensitive details. Consider replacing

105-107: Use consistent logging mechanismReplace
console.errorwithelizaLogger.errorfor error logging to maintain consistency across the codebase.
192-195: Standardize error loggingConsider using
elizaLogger.errorinstead ofconsole.errorto ensure uniform logging practices.

1-20: Clean and well-structured plugin implementation!The plugin follows the standard pattern and includes all necessary components.
packages/plugin-cronos/src/types/index.ts (1)
6-13: Well-defined transaction interface!Good use of
Hextype from viem for type-safe blockchain interactions.packages/plugin-cronos/package.json (1)
24-28: Verify viem version compatibility.The plugin uses viem v2.0.0 which was recently released. Ensure compatibility with the core framework.
✅ Verification successful
✅ viem v2.0.0 usage is compatible with core framework
The core package only uses basic client creation features from viem which remain stable across versions. The v2 breaking changes don't affect this minimal usage pattern.
🏁 Scripts executed
The following scripts were executed for the analysis:
