ASTRA Coin is a “circulating value token” that connects the real and digital economies. Unlike typical cryptocurrencies focused on speculation, ASTRA derives its value from real activities such as product sales, content creation, and community participation.
Its core model follows a value loop: “Consumption → Reward → Asset → Reuse.” Users earn rewards through commerce platforms, convert them into ASTRA, and use them as assets—turning consumption into value creation. Integrated with NFT404, DAO governance, and global commerce, ASTRA enables fair distribution and sustainable growth. It is not just a tradable coin, but a Web3 infrastructure built on real economic activity.

The Metaverse is a virtual world based on virtual reality, augmented reality, and blockchain technology, where users can interact, trade, and have diverse experiences. With technological advancements, the Metaverse has become an integral part of people's lives, providing new platforms for interaction and economic activity to users worldwide. In line with this trend, ASTRA has developed a leading program that connects the virtual and real economies by creating a sustainable global shopping mall and a GNK wallet.

NFT-404 is our hope.
NFT 404 is a hybrid NFT protocol combining ERC-20 and ERC-721 standards, enabling a single NFT to be split into tradable token units. It offers both non-fungibility and liquidity, bridging the gap between collectible uniqueness and financial usability in decentralized ecosystems.
“Fractionalize and trade NFTs like tokens. Empower ownership, liquidity, and Web3 commerce.”
