- Dec 25, 2021 · 3 years agoA reentrancy guard is a security mechanism implemented in smart contracts to prevent potential attacks in the cryptocurrency industry. It works by limiting the number of times a contract can be called within a single transaction. This prevents malicious actors from exploiting reentrancy vulnerabilities, where they repeatedly call a contract to drain its funds before the contract can update its internal state. By implementing a reentrancy guard, developers can ensure that their contracts are protected against such attacks, providing a more secure environment for cryptocurrency transactions.
