Astrochain's focus is on space exploration and astronomy through an interactive community that involves NFTs of astronomical data and education via the metaverse, which does not directly align with the themes of #ReFi #DecSi #community #publicgood #Phangan #global_ecosystem that are at the core of the EcoSynthesisX Spring Round on Polygon. The project does not mention or appear to specifically address environmental or local community development initiatives.
