## Smart Contract Idempotency

Smart contract idempotency is a design pattern where executing a function multiple times with the same parameters results in the same state change as a single execution. This is critical for robust decentralized finance applications, as it prevents errors during network retries or transaction failures.

If a user sends a transaction that gets stuck or re-broadcasted, an idempotent contract ensures the balance is not deducted twice. This property protects users from financial loss and ensures the integrity of the ledger.

It is a vital concept in smart contract security, preventing common exploits related to double-spending or improper state management.
