According to MarsBit, the multi-chain decentralized over-collateralized stablecoin USDD made its debut at the 2026 Istanbul Blockchain Week. USDD is a decentralized stablecoin that operates on smart contracts and uses an over-collateralization mechanism, meaning users must deposit crypto assets worth more than the stablecoins they mint, ensuring price stability. It is designed to run on multiple blockchain networks, enhancing interoperability and liquidity.
The stablecoin market has grown rapidly, and over-collateralized models are seen as a key direction for decentralized stablecoins, offering stronger risk resistance compared to algorithmic stablecoins. The launch of USDD provides a new option for the market.
