# Reentrancy Vulnerability ⎊ Area ⎊ Resource 1 --- ## What is the Exploit of Reentrancy Vulnerability? Reentrancy vulnerabilities represent a critical class of security flaws within smart contracts, particularly those managing external calls to other contracts. This arises when a contract’s function recursively calls itself before the initial execution completes, potentially altering state assumptions during the original transaction. Consequently, attackers can repeatedly withdraw funds or manipulate contract logic before balances are updated, leading to unauthorized fund extraction or systemic disruption. ## What is the Countermeasure of Reentrancy Vulnerability? Mitigation strategies center on employing checks-effects-interactions patterns, where state changes are completed before external calls are made, and utilizing reentrancy guards to prevent recursive function calls. Implementing pull-over-push payment mechanisms, where recipients initiate withdrawals, further reduces the attack surface by eliminating the need for the contract to directly send funds. Thorough auditing and formal verification techniques are essential components of a robust defense against these exploits. ## What is the Architecture of Reentrancy Vulnerability? The underlying architectural weakness stems from the Ethereum Virtual Machine’s (EVM) execution model, which allows for interleaved execution during external calls. This characteristic, while enabling complex interactions, creates a window of opportunity for malicious actors to exploit state inconsistencies. Designing contracts with a clear understanding of the EVM’s behavior and prioritizing deterministic execution paths are crucial for building secure decentralized applications. --- ## [Smart Contract Risk](https://term.greeks.live/definition/smart-contract-risk/) Potential for financial loss due to code vulnerabilities, logic errors, or unforeseen interactions in automated protocols. ⎊ Definition ##
