Important Review skippedAuto incremental reviews are disabled on this repository. Please check the settings in the CodeRabbit UI or the You can disable this status message by setting the WalkthroughWalkthroughThe changes involve the implementation of a default liquidity cap for newly created ZRC20 tokens, enhancing the management of liquidity within the system. Key modifications include the introduction of a constant for the default liquidity cap, refactoring of related functions to improve clarity and error handling, and updates to testing procedures to ensure the correct application of the liquidity cap.

5-8: Well-documented constant addition.The addition of
DefaultLiquidityCapis well-documented and clearly explains its purpose and usage. This change should help standardize the deployment of new ZRC20 tokens and enhance security by providing a sensible default liquidity cap.e2e/txserver/zeta_tx_server.go (2)
582-593: Good encapsulation of liquidity cap initialization.The
initializeLiquidityCapfunction encapsulates the logic for setting the liquidity cap, which enhances modularity and maintainability. The use ofMustGetAccountAddressFromNamewithin this function assumes that the operation will not fail, which is generally safe in controlled test environments but might need reconsideration for production code to handle potential errors gracefully.
595-607: Effective encapsulation of ZRC20 address fetching.The
fetchZRC20FromDeployResponsefunction effectively encapsulates the logic for extracting the ZRC20 address from a deployment response. This separation of concerns improves the readability and maintainability of the code. Consider adding more robust error handling or validation if the context of use expands beyond controlled test scenarios.changelog.md (1)
25-25: Review the changelog entry for setting the default liquidity cap.The entry "2802 - set default liquidity cap for new ZRC20s" is correctly placed under the "Refactor" section. This placement is appropriate as it reflects a change in the system's behavior rather than a new feature or a bug fix. The link to the pull request provides a direct reference for further details, which is a good practice for transparency and traceability.

319-319: Verify the Liquidity Cap AssertionThe new assertion checks if the
LiquidityCapis correctly set toDefaultLiquidityCap * 8. Ensure that theDefaultLiquidityCapconstant is defined with the expected value and that the multiplication by 8 is intentional. If these conditions are met, the assertion is correctly validating the new functionality.Verification successful
Verify the Liquidity Cap Assertion
The
DefaultLiquidityCapis defined as1000inx/fungible/types/zrc20.go. The test assertion multiplies this value by8, resulting in aLiquidityCapof8000. This multiplication appears intentional and aligns with the test's purpose to validate the correct setting of the liquidity cap during ZRC20 contract deployment. The assertion is correctly validating the new functionality.
