## Error Handling Patterns

Error handling patterns in smart contracts are structured approaches to identifying, reporting, and managing potential failures during execution. These patterns include the use of require, assert, and revert statements to validate inputs and state conditions before proceeding.

By implementing robust error handling, developers can prevent unexpected behavior and protect users from malicious or buggy contract interactions. These patterns allow the contract to fail gracefully rather than executing in an undefined state.

In financial applications, clear error messages and predictable failure modes are essential for user experience and system reliability. They help traders understand why a transaction failed, allowing them to take corrective action.

Good error handling is a key indicator of a well-audited and secure decentralized protocol.
