Yes, USDD is still pegged at $1 on Justlend. This is because it is programmed as one Justlend dollar, meaning that its value will always remain the same regardless of market fluctuations. This provides stability for users, as they can trust that their funds will not be affected by changes in the market. At the same time, other stablecoins are not pegged to the US Dollar and can have their own rates depending on the market. This allows users to benefit from the potential of market fluctuations, while still having the security of a stablecoin.
