Implementing Asset Evolution Feature in Laos

[magecnion]

PR Type:

Enhancement

---

PR Description:

This PR introduces the asset evolution feature in the Laos project. The main changes include the addition of the 'evolve' function in the LaosEvolution trait, which allows for updating the token URI of an existing token. The PR also includes updates to the precompile and pallet tests to ensure the correct functionality of the new feature. Additionally, the LaosEvolution.sol contract has been updated to include the 'evolveWithExternalUri' function and the corresponding 'MetadataUpdate' event.

PR Main Files Walkthrough:

files:

ownership-chain/pallets/laos-evolution/src/traits.rs: Added the "evolve_with_external_uri" function to the LaosEvolution trait.
ownership-chain/pallets/laos-evolution/src/lib.rs: Implemented the "evolve_with_external_uri" function in the LaosEvolution trait for the Pallet. Also, added the "EvolvedWithExternalTokenURI" event and the "AssetDoesNotExist" error.
ownership-chain/pallets/laos-evolution/src/tests.rs: Added tests for the "evolve_with_external_uri" function.
ownership-chain/precompile/laos-evolution/src/lib.rs: Added the "Evolve" action and implemented its execution in the "execute" function.
ownership-chain/precompile/laos-evolution/src/tests.rs: Added tests for the "Evolve" action.
ownership-chain/precompile/laos-evolution/contracts/LaosEvolution.sol: Added the "evolveWithExternalUri" function and the "MetadataUpdate" event.

PR Analysis

• 🎯 Main theme: Implementing the 'evolve' feature in the LaosEvolution system
• 📝 PR summary: This PR introduces the 'evolve' feature in the LaosEvolution system, allowing tokens to evolve with an external URI. The feature is implemented in the LaosEvolution pallet and its corresponding precompile. The PR includes the necessary changes in the Rust code, Solidity interface, and also adds relevant tests to ensure the correct functionality of the new feature.
• 📌 Type of PR: Enhancement
• 🧪 Relevant tests added: Yes
• ⏱️ Estimated effort to review [1-5]: 3
  description: >-
  The PR is of moderate size and complexity. It introduces a new feature in the system, which requires understanding the existing codebase and the new changes. The PR includes changes in multiple files, including Rust and Solidity code, and also includes tests, which need to be reviewed for correctness and coverage.
• 🔒 Security concerns: No
  description: >-
  The PR does not seem to introduce any obvious security concerns. The new feature does not involve sensitive data or operations, and the changes are mostly confined to the LaosEvolution system. However, a thorough security review should still be conducted to ensure the robustness and security of the new feature.

PR Feedback

• 💡 General suggestions: The PR is generally well-structured and includes relevant tests for the new feature. However, it would be beneficial to include more comments in the code explaining the logic and purpose of the new feature, especially for complex functions. This would make the code easier to understand for other developers.

• 🤖 Code feedback:

  • relevant file: ownership-chain/pallets/laos-evolution/src/lib.rs
    suggestion: Consider adding checks to ensure that the token_uri provided in the evolve_with_external_uri function is valid and meets the necessary requirements (e.g., it is a valid URL, it does not exceed a certain length, etc.). This can help prevent potential issues and improve the robustness of the system. [important]
    relevant line: "+ fn evolve_with_external_uri("

  • relevant file: ownership-chain/precompile/laos-evolution/src/lib.rs
    suggestion: It might be beneficial to add error handling for the case where the token_uri_raw cannot be converted into token_uri in the Action::Evolve branch of the execute function. This can help provide more informative error messages and make debugging easier. [medium]
    relevant line: "+ let token_uri = token_uri_raw.try_into().map_err(|_| revert("invalid token uri length"))?;"

  • relevant file: ownership-chain/pallets/laos-evolution/src/tests.rs
    suggestion: Consider adding more tests to cover edge cases and potential error scenarios in the evolve_with_external_uri function. For example, tests for cases where the token_uri is invalid, the collection_id or token_id does not exist, etc. This can help ensure the robustness of the new feature. [important]
    relevant line: "+fn evolve_with_external_uri_happy_path() {"

  • relevant file: ownership-chain/precompile/laos-evolution/contracts/LaosEvolution.sol
    suggestion: In the Solidity interface, consider adding a require statement in the evolveWithExternalUri function to check that the tokenURI argument is valid (e.g., it is a non-empty string). This can help prevent potential issues and improve the robustness of the system. [medium]
    relevant line: "+ function evolveWithExternalUri("

  The PR is of moderate size and complexity. It introduces a new feature and modifies several files, including tests. However, the changes are well-documented and the code is clean, which should make the review process smoother.
• 🔒 Security concerns: No
  The PR does not seem to introduce any obvious security concerns. However, a thorough security review should be conducted to ensure that there are no vulnerabilities, especially since this is a blockchain-related project.

PR Feedback

• 💡 General suggestions: The PR is well-structured and the code changes are clear. The addition of the 'evolve' function and the corresponding tests are a good practice. However, it would be beneficial to ensure that all edge cases are covered in the tests, especially for error handling.

• 🤖 Code feedback:

  • relevant file: ownership-chain/precompile/laos-evolution/src/lib.rs
    suggestion: Consider handling the case where the token URI length is invalid more explicitly. Instead of just reverting with a generic "invalid token uri length" message, you could provide more information about what the valid length should be. [medium]
    relevant line: .map_err(|_| revert("invalid token uri length"))?;

  • relevant file: ownership-chain/precompile/laos-evolution/src/tests.rs
    suggestion: It would be beneficial to add more tests for the 'evolve' function, especially for edge cases and error handling. For example, what happens if the token URI is invalid or if the token does not exist? [important]
    relevant line: let result = Mock::execute(&mut handle).unwrap();

  • relevant file: ownership-chain/precompile/laos-evolution/contracts/LaosEvolution.sol
    suggestion: Consider adding a comment to explain the purpose and usage of the 'MetadataUpdate' event. This would make the code more readable and maintainable. [medium]
