Various strategy fixes #9
Conversation
WalkthroughThe recent changes across several smart contract files enhance the validation and management of repo tokens, improve error handling, and refine event emissions. Notable modifications include the removal of certain parameters from function signatures, the introduction of new error types, and clearer structuring of deposit and strategy management functions. These adjustments aim to streamline operations, improve code readability, and bolster security. Changes

Blacklist and Deployment Checks Verified in
sellRepoTokenThe
sellRepoTokenfunction insrc/Strategy.solcorrectly implements the necessary checks. It includes thenotBlacklisted(repoToken)modifier to ensure the token is not blacklisted and checks if the token is valid and deployed by using_isTermDeployed(repoToken). These measures ensure that only valid and non-blacklisted tokens are processed.
