## Error Handling in Smart Contracts

Error handling in smart contracts refers to the mechanisms used to manage unexpected states or invalid operations during the execution of code on a blockchain. Because smart contracts are immutable once deployed, developers must implement robust logic to prevent state corruption or the permanent loss of funds.

This involves using require, revert, and assert statements to validate conditions before proceeding with state changes. When a condition fails, the transaction is reverted, meaning all changes made during that transaction are undone to maintain the integrity of the contract state.

Effective error handling is critical in financial derivatives and decentralized exchanges to ensure that invalid orders or under-collateralized positions do not compromise the protocol. Without these safeguards, malicious actors could exploit edge cases to drain liquidity or manipulate market data.

It is a foundational practice in smart contract security to ensure predictable and safe behavior under all conditions.
