[Nithin1506200]

Analyze and Remove Unused Functions from crates/router/src/connector/utils.rs

Description:

There are functions in the crates/router/src/connector/utils.rs file that appear to be unused across the router crate. For

example: • validate_currency is defined in utils.rs but is not used anywhere in the codebase. This function can be safely removed.

Task:

• Perform a comprehensive analysis of all the functions present in crates/router/src/connector/utils.rs. • Identify any functions that are not referenced anywhere in the router crate which are in utils. • Remove such unused functions to reduce dead code and improve maintainability.
