# 8. Blockchain Utilisation During development, a blockchain platform is needed for the issuance of assets in the form of NFTs and $KOL tokens. We choose BNB Chain as the main platform for the development of King of Legends. BNB Chain has outstanding advantages: low transaction fees, popular NFT standard, and especially Binance's large user ecosystem. In the future, King of Legends will also be optimized with other Blockchain platforms, such as Solana and Polygon. --- # 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.
