The decentralized stablecoin USDD has launched a new dual-chain reward campaign in collaboration with GateDEX, offering a total prize pool of $50,000. The campaign, which runs from June 30 to July 30, spans both the Ethereum and BNB Chain networks. Participants on the Ethereum chain can earn a base 4% annualized yield with access to a 20,000 USDD prize pool, while those on the BNB Chain can also earn a 4% yield with a 30,000 USDD prize pool. Rewards can be enhanced by combining with GateDEX's "Opening Bonus" and USDD staking challenges. Users can join the campaign by converting USDT to USDD and staking it as sUSDD through the GateDEX Earn-Stablecoins-Bonus section. Existing user earnings will continue seamlessly. New participants are advised to ensure they have sufficient ETH or BNB for gas fees before engaging in the campaign.
