Security features to prevent flash loan attacks on a Pancakeswap clone script?

In the rapidly evolving DeFi landscape of 2026, security is the ultimate cornerstone of platform trust. When deploying a Pancakeswap clone script, the most critical technical challenge is mitigating the risk of flash loan attacks, which exploit price discrepancies across decentralized exchanges. To prevent these vulnerabilities, a professional-grade script must implement robust, decentralized price oracles. Relying on a single internal liquidity pool for pricing is a major risk; instead, integrating Time-Weighted Average Price (TWAP) oracles from providers like Chainlink ensures that the script uses an aggregate price that cannot be manipulated within a single transaction block.

Furthermore, a secure Pancakeswap clone script should feature "re-entrancy guards" and strict logic to prevent multiple swaps from occurring in the same block by the same address if a price anomaly is detected. Implementing a "Flash Loan Fee" or a slight delay in price updates can also disincentivize attackers by making the exploit mathematically unprofitable. Additionally, the smart contracts should undergo rigorous formal verification and include "Circuit Breakers"—automated triggers that pause trading if an unusual, high-volume price slippage occurs. By prioritizing these advanced security benchmarks during the development phase, platform owners can protect their liquidity providers and build a resilient DEX that stands up to the sophisticated threats of the 2026 decentralized economy.
