AETHERIS Day 2: Flash Loan Attack Detector — Component #4/730

Building AETHERIS in Public — Day 2

Phase 1: The Invisible Shield
Before moving money, protect it. The security foundation of AETHERIS.

Component: Flash Loan Attack Detector

The Flash Loan Attack Detector utilizes block-level liquidity snapshot comparisons to identify potential attacks, reducing the risk of financial losses such as the $500M+ incurred by DeFi in 2023-2024. By detecting signature manipulation patterns in real-time, this detector can prevent flash loan attacks with a response time of less than 1 block, or approximately 15 seconds, significantly improving the security of decentralized finance protocols.

Why This is Production-Grade

Flash loan attacks cost DeFi $500M+ in 2023-2024. This detects the signature manipulation pattern in real time before the attack completes.

Assembly Optimization

Assembly block.number and balance delta calculations for zero-overhead monitoring
