## Transaction Malleability Risks

Transaction Malleability Risks refer to vulnerabilities where an attacker can modify the non-essential parts of a transaction, such as the signature, without changing the underlying transaction details. While the funds go to the correct recipient, the transaction hash changes.

This can lead to issues in protocols that rely on the transaction hash for tracking or dependency management. In some cases, this has been used to trick exchanges into thinking a withdrawal failed, prompting them to resend the funds.

Modern blockchain protocols have implemented fixes, such as Segregated Witness in Bitcoin, to eliminate malleability by separating the signature from the transaction data. Understanding these risks is crucial for developers building financial applications that interact with the blockchain.

It highlights the importance of using transaction hashes correctly and designing protocols that are immune to such manipulations. This knowledge helps in building robust, predictable systems for digital asset exchange.
