What Are Storage Collisions and Why Do They Matter?
Ethereum smart contracts store data in a structure called a storage trie. When this storage data is not carefully aligned, two or more variables can accidentally overlap in the same storage slot, leading to storage collisions.
This might sound harmless, but in practice, storage collisions can break contract logic or even open severe security holes. A well-known example is the Audius hack, where misaligned storage caused a major exploit, resulting in millions of dollars in losses.
How Our Research Tackles the Problem
Most existing tools rely on bytecode analysis, which often fails to detect complex collisions due to limited visibility into the actual storage layout. Our tool, SlotCollider, powered by SmartMuv’s Deep Storage Explorer, goes further:
- Source Code + On-Chain Analysis – Providing a deeper understanding of storage layouts and complex data structures.
- High Accuracy – We analyzed 4,890 smart contracts and uncovered 6,558 additional collisions that existing tools missed.
- Proactive Detection – Identifying vulnerabilities before they become exploits.
Why SmartMuv Deep Storage Explorer Matters
SmartMuv is the first of its kind deep storage data explorer designed to reveal hidden storage mappings and complex contract data. Using SmartMuv, we can:
- Detect storage misalignments and slot collisions.
- Uncover hidden vulnerabilities that are invisible to standard block explorers.
- Provide AI-powered auditing insights for developers and auditors.
Are Your Smart Contracts Safe?
If your project relies on Ethereum smart contracts, storage collisions could be a silent killer lurking in your code. Don’t wait for a costly exploit to happen!
