It calculates a risk score and levels by examining various risk factors like Admin Key, Supply Key, KYC Key, etc.
• Airdrop Verifier - The Airdrop Verifier is a utility that simplifies the process of organizing airdrops for Hedera tokens. Users can input a Token ID and a list of account IDs to which they wish to airdrop tokens. The application generates a list of addresses either associated with the token or having available auto-association slots, ensuring efficient and targeted airdrops.
• Rarity Inspector - This project allows users to upload a .zip file through a dropzone to check how NFTs are presented (displayed in a gallery as cards that can be clicked to read detailed information about them) and their "rarity". The project presents charts showing these data and several other features. Additionally, sorting and filtering options are available to simplify data browsing.
• Token Holders List Builder - The Token Holders List Builder is a tool designed to efficiently generate lists of token holders who meet specific criteria, like holding a minimum number of NFTs from a particular collection. This can be especially useful for identifying key stakeholders or organizing targeted marketing campaigns within the NFT community. By automating what would otherwise be a complex data retrieval process, this tool simplifies analytics and community management for NFT projects.
