In the web 3.0 SocialFi field, it is satt that can set off a wave of decentralized social asset revenue aggregation platforms. SatT, as a liquidity mining + lending + cross-chain + oracle + social as a whole, opens up the decentralized social asset income aggregator of DeFi assets on the chain such as Heco, BSC, ETH and Polkadoot, attracting many advocates and followers.
SATT is based on the SmartX public chain development and distribution, on SATT people can easily create their own theme community and services without any coding and deployment. SATT adopts the DAO organizational structure, and in its product forms, there are liquidity mining, revenue aggregators, transaction aggregations, multi-chain wallets, decentralized social networking, etc., to meet the all-round needs of users and funds, and to help users achieve privacy data security, community rewards, data asset value and other returns to individuals
