what's Satsume?

Satsume is a decentralized protocol providing foundational infrastructure for crypto-native eCommerce, akin to Shopify for Web3. It allows creators and brands to launch on-chain storefronts, execute transparent promotions through smart contracts, and transform consumer interactions into tokenized stakes. Purchases generate programmable economic primitives like "Drawing," directing sales revenue into autonomous prize pools resolved via Chainlink VRF for verifiable randomness. This enables permissionless incentives, co-ownership communities, and yield-bearing receipts, bridging speculation to practical spending without fiat ramps or volatility exposure. Operating on Ethereum Sepolia testnet, Satsume features a simulation marketplace for virtual goods and NFTs payable in $NUSD, claimable via the Mindverse Genesis points system. Users earn Neurobits through quests, browsing, and transactions, ascending leaderboards for rewards. The protocol prioritizes auditable smart contracts, ZK privacy, and multi-chain scalability, empowering builders with open APIs to integrate DeFi and real-world assets into commerce flows.
