The Dex.top Decentralized Exchange officially launched the “50 Plan”, which selects 50 public chains for the world and comprehensively builds a public chain ecosystem through the “sea, land and air” cooperation model. This announcement is a strategic partnership with IOST's main network, allowing users to store, use and trade assets based on IOST in a collaborative wallet, and will be based on more applications on the main online line. This move confirms the official landing of the new model of “sea, land and air” cooperation, and is the first step of the Dex.top planning blueprint. It will then be combined with more main networks to target potential and explosive ecological public links. Through the "sea, land and air", that is, the three-in-one cooperation mode of exchanges, wallets and applications, the entire public chain ecological economy will be built.
