Justin Sun has recently made a public call on platform X inviting centralized exchanges (CEX) to collaborate, offering an attractive 20% annualized reward in USDD. In addition, he introduced a unique incentive of a 1:1 USDT/USDD non-destructive exchange, enhancing the appeal for potential exchange partners.This strategic move follows Sun’s announcement that despite USDD having no exchange support initially and relying purely on on-chain transactions, it managed to surpass a supply of 100 million within just three days of its launch. This rapid growth highlights the market’s positive response and the potential for further expansion through collaboration with CEXs.Sun’s offer aims to significantly extend USDD’s reach and usability, providing an excellent opportunity for exchanges looking to attract a larger user base and increase trading volumes through competitive yield offerings.
