# Reentrancy Attacks ⎊ Area ⎊ Resource 2

---

## What is the Exploit of Reentrancy Attacks?

⎊ This specific vulnerability allows an external contract to recursively call back into the originating contract before the initial function execution has completed its state updates. Such a loop can be used to repeatedly withdraw funds or execute actions based on stale data, effectively draining collateral pools. The mechanism bypasses standard checks by exploiting the order of operations within the execution environment.

## What is the Code of Reentrancy Attacks?

⎊ Flaws in the smart contract code, typically related to external calls that transfer value before internal state changes are finalized, create the condition for this attack vector. Rigorous code review must specifically target the sequence of external calls versus internal accounting updates. Ensuring checks-effects-interactions ordering is strictly followed prevents this class of failure.

## What is the Vulnerability of Reentrancy Attacks?

⎊ In the context of crypto derivatives, this is particularly dangerous as it can compromise the integrity of escrowed collateral or the settlement logic for options contracts. A successful attack can lead to a complete loss of funds locked in the affected smart contract. Identifying and patching this weakness is a critical component of protocol security.
