Answer 2: Klaytn (KLAY) is a blockchain-based platform developed by the South Korean technology giant Kakao. It is designed to provide a secure and efficient way to enable decentralized applications and services. Unlike other blockchain networks, Klaytn does not have a contract address because it is not a contract-based asset. Instead, Klaytn provides an ecosystem of services such as its Klaytn Wallet, Klaytn Governance Council, and Klaytn BApp Store, which enable users to interact with the network and access services without the need for a contract address.
