Walkthrough

The recent changes focus on enhancing the safety and consistency of the Account struct in the multisig accounts module. Specifically, the safeAdd function is updated to prevent overflow errors by using a new variable newSum. Additionally, the UpdateConfig method has been modified for consistency in variable naming and to improve error handling during weight calculations.

Changes

File Path	Change Summary
x/accounts/defaults/multisig/account.go	Updated safeAdd function to use newSum variable for overflow prevention.
x/accounts/defaults/multisig/update_config.go	Changed variable adderr to addErr for consistency and improved error handling during weight calculation.

398-401: Refactor in safeAdd function improves overflow detection.

The use of newSum for overflow checking before updating sum is a good practice as it prevents the original sum from being altered in case of overflow. This change enhances the reliability of the function by ensuring that the state is only modified after a successful operation.
