Gate Research Institute: This week, Hub.xyz, Nomisma, Ethereal, and Kittenswap have all provided users with opportunities to engage in the Web3 ecosystem. Hub.xyz trains AI agents through interaction on the X platform and incentivizes users' participation with IQ points. Nomisma, as a Layer 1 sidechain in the Chromia ecosystem, leverages relational blockchain technology to solve issues faced by traditional blockchains. Ethereal offers institutional-level trading performance and uses USDe as collateral. Kittenswap is characterized by low gas fees and its LIQUID token mechanism, providing lending services and being community-governed. These projects attract users through airdrops, where users can earn token rewards by completing tasks, engaging in social interactions, and more.
