Single-block transaction attacks involve executing a sequence of transactions within the same block to manipulate prices and exploit decentralized finance protocols. This type of attack leverages the atomic nature of blockchain transactions, where all actions within a single block are either fully executed or entirely reverted. The attacker typically uses a flash loan to acquire large amounts of capital, execute the manipulation, and repay the loan within the same block.
Transaction
The attack sequence often involves borrowing assets via a flash loan, using those assets to manipulate the price of an underlying asset on a decentralized exchange, and then exploiting a derivatives contract or oracle based on the manipulated price. The final step involves repaying the flash loan, leaving the attacker with the profit from the exploit. This entire sequence occurs before the block is finalized.
Mitigation
Mitigation strategies focus on preventing price manipulation within a single block. Protocols often implement time-weighted average price (TWAP) oracles, which calculate prices based on data aggregated over multiple blocks, making single-block manipulation ineffective. Additionally, protocols can implement circuit breakers that automatically pause operations during extreme price volatility to prevent immediate exploitation.
