Who hunted ContractScan?
ContractScan was hunted by Josh Kim. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

Josh Kim
Hey Hunters!
I'm the maker of ContractScan — the fastest smart contract security scanner.
We got tired of running Slither, MythX, Semgrep, Aderyn, and 3 more tools separately and then spending hours correlating results.
So we built ContractScan: 5 audit engines in parallel → one clean report in ~30 seconds.
What makes it different:
Completely free QuickScan — no signup, just paste code or contract address
Supports Solidity + Rust (Near) — not just EVM
Every finding linked to real exploits with actual loss amounts (The DAO, Ronin, etc.)
Already integrated 686 DeFi hacks + major audit reports
We're currently in public beta and QuickScan is 100% free.
Would love your honest feedback — especially on false positives and which vulnerability types matter most to you.
