EOS cross-chain currency is the mapping of mainstream blockchain network assets on the EOS network. Users holding mainstream blockchain assets can exchange assets for the same amount of cross-chain assets on the EOS network through the cross-chain gateway, and users can use these assets in supported DApps or decentralized exchanges. Cross-chain coins enrich the asset diversity of the EOS ecosystem, and at the same time provide great convenience to users of other blockchain networks who want to participate in the EOS ecosystem. EUSD, in particular, has achieved a stable 1:1 anchoring relationship with the original network assets because it indirectly anchors the U.S. dollar by anchoring USDT, which can provide users with a stable choice in a rapidly changing market.
