Walkthrough
The recent updates across several smart contracts introduce enhanced functionality and improved error handling. Key changes include the addition of the TSS_ROLE for refined access control, rigorous input validation checks, and new error types for better debugging and user experience. These modifications aim to create a more robust and versatile framework for interactions within the contracts, ultimately boosting their security and operational capabilities.

User->>Contract: Call function (e.g., deposit)

RoleManagement-->>Contract: Role validated

New roles and checks take glorious flight.
TSS_ROLE hops in, with a skip and a cheer,
Validations in place, we’ve nothing to fear!
Contracts now flourish, secure and keen,
In our blockchain garden, all is serene! 🌼

bumps v2 coverage from ~70% to ~80%, fixes some smaller issues, extends simple checks of external functions a bit
@lumtis question about more tests - the only protocol contract that is not tested is SystemContract, simply because we are not using full functionality, there are no tests for it in v1, and it will be replaced by some sort of registry contract, so no point to add tests for whole contract now
this contract is currently under
test/utilsso it's not impacting coverage, should we move it undersrc/zevmand exclude from coverage?Summary by CodeRabbit
