## Custom Error Types

Custom error types are a feature in Solidity that allows developers to define specific, named errors to improve gas efficiency and error clarity. Instead of using string-based error messages that consume significant gas to store and return, custom errors use a unique identifier.

This allows front-end applications to catch specific failure scenarios and display user-friendly messages without unnecessary overhead. In complex derivative protocols, these errors can be used to signal specific margin violations or market state issues.

They are more descriptive and efficient than generic reverts. By using custom errors, developers can create a more robust communication layer between the smart contract and the user interface.

This is a best practice for modern contract development, enhancing both the developer experience and the end-user journey.
