Bug Hunter Analysis of NFT Protocols
What are NFTs?
Non-Fungible Tokens (NFTs) are unique digital tokens recorded on-chain that act as tamper-proof certificates of ownership for a specific item— typically artwork, media files, game assets, or membership passes.
Unlike fungible cryptocurrencies, every NFT carries a one-of-a-kind ID tied to its contract address, so it cannot be swapped 1-for-1 with another token.
This baked-in uniqueness allows:
- verifiable ownership & provenance,
- programmable features such as royalties or gated access, and
- instant portability across wallets, marketplaces, and apps.
As NFT platforms execute hundreds of thousands of on-chain actions per day, smart-contract reliability is critical. Manual reviews are slow and error-prone, and legacy static-analysis tools generate too many false positives.
Bug Hunter is an automated Solidity code reviewer that delivers precise, low-noise insights early in development, with < 5 % false-positive rate. The following sections explore its performance on a range of NFT protocols and the key vulnerabilities it detects.
