According to Wu, MakerDAO recently tweeted that the supply of DAI has surged by nearly 1 billion in the past two months, from 4.4 billion to 5.4 billion. This increase occurred after SparkLend adjusted the Stability rate and DAI borrowing APY, as well as the DSR interest rate. In addition to the supply growth, DAI set a new record in April, with on-chain transactions reaching US$636.72 billion, becoming the stablecoin with the largest monthly on-chain transaction volume. At the same time, the Dai Savings Rate (DSR) has also shown positive momentum in recent months, with total deposits exceeding US$2 billion last week.
