# FAQ **- Is this collection 100% fully on-chain?** Yes. Each token is stored on-chain, including the metadata and artwork. **- What does edit metadata mean?** Metadata is stored on-chain and reflected in the tokenURI function in the contract. There's a special attribute called "Metadata" that can store a string (text) of up to 100 characters. That attribute is included when NFT marketplaces (Blur, OpenSea, etc) ask the contract for information about a token. **- What happens to burned art?** Burned tokens have their attributes wiped and artwork replaced with a special design. Burned tokens cannot be traded, since they're no longer owned by anyone. **- What’s the system UI font?** The system UI font is a way to ensure maximum artwork compatibility across devices and operating systems.

Tokens that are Edited can only be edited again if they are a Super Rare. Tokens that are Not Edited can be edited if they are a Blank, or if 4 other Common tokens are being burned. **- What is the burned token filter?** NFT marketplaces often implement filters for token attributes. Metadate/a tokens have a "Burned" attribute which can be used to filter out (or in) burned tokens on marketplaces. **- Why is (1) token already minted?** The contract was programmed to mint token ID #1 to auction for charity. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
