Clipper — Decompiler

Traditional decompilers have existed for years (notably, Panoramix and the older Remix decompiler). However, they struggle with modern Solidity quirks: the IR-based compilation pipeline (via Yul), optimized bytecode, and the complex control flow of upgradeable proxies. They often produce code that is logically correct but structurally illegible—filled with goto statements and anonymous variables named var0 , var1 , var2 . Clipper was built not just to decompile, but to restore intent . Developed by a team of security researchers who grew tired of reverse-engineering hacks under a ticking clock, Clipper focuses on three core pillars:

Clipper is to EVM reverse-engineering what the microscope was to biology. It doesn't create new dangers; it merely illuminates the ones that have always existed in the dark. For anyone serious about blockchain security, Clipper isn't just a nice-to-have tool—it is the new standard of care. clipper decompiler

It is no longer enough to just verify your contract on Etherscan. In the future, auditors will run your bytecode through Clipper to see if the decompiled logic matches your claimed source code. Clipper was built not just to decompile, but

Clipper destroys that illusion. It forces transparency. If your contract is deployed on a public blockchain, Clipper assumes it is open source—regardless of whether you uploaded the Solidity files to a block explorer. For anyone serious about blockchain security, Clipper isn't

Suddenly, the opaque attack vector becomes a readable script. The researcher sees that the attacker manipulated the oracle before calculating the debt. Clipper didn't just list the opcodes; it reconstructed the narrative. Of course, a powerful decompiler is a double-edged sword.

Don't trust the source code. Trust the bytecode.
