Gate DEX will run a USDD dual-chain incentive campaign from May 31, 2026 to June 30, 2026, offering 30,000 USDD on BNB Chain and 20,000 USDD on Ethereum for a total reward pool of 50,000 USDD. During the same period, USDD Earn APY is listed at 8.21% on Ethereum and 7.68% on BNB Chain. The campaign is positioned as an effort to expand USDD cross-chain liquidity and reinforce its role as a multichain stablecoin infrastructure asset. The article also notes references to USDD, BNB Chain (linked to BNB) and the TRON ecosystem (linked to TRX), with TRX described as USDD’s underlying issuance chain and BNB as one of the incentive deployment chains.
