Luna (LUNC) and TerraUSD (UST) are two native tokens of the Terra network, a blockchain-based project developed by Terra Labs in South Korea.
The Terra blockchain is built on Cosmos SDK; a framework that allows developers to create custom blockchains and build their own decentralized applications on top of Terra for various use cases.
The Terra ecosystem contains some natively built projects. These include non-fungible token (NFT) collections, decentralized finance (DeFi) platforms and Web3 applications.
