## Reentrancy Attack Mitigation

Reentrancy attack mitigation involves specific coding practices and architectural choices that prevent attackers from recursively calling a function before the initial state is updated. This is a common vulnerability in smart contracts where an attacker drains funds by repeatedly calling a withdrawal function.

Mitigation strategies include the use of checks-effects-interactions patterns, reentrancy guards, and mutexes. By ensuring that state changes occur before any external calls are made, developers can effectively block this class of attack.

These safeguards are foundational to secure protocol design and are a standard requirement in professional smart contract development.
