According to CoinDesk news, data from Digital Assets Data show that as of January 17, collateral assets worth about $ 400 million were locked into the MakerDAO protocol stability system. At the same time, the number of Ethereum locked by the Dai system reached an all-time high of nearly 2.5 million, accounting for about 2.2% of the total supply of Ethereum. In addition, the value of DAI locked into DeFI has recently increased to $ 50 million, a 65% year-on-year increase. Although the DeFi market has exploded in the past 12 months, activity has only occurred at a small percentage of addresses. On the old Maker agreement, about 155,000 CDPs were created on "Single Collateral Sai". However, as of January 15, 77% held less than 0.05 ETH ($ 8.10 as of press time). In addition, only one account holds 171,000 PETH, which accounts for 27% of the total amount of PETH. Similarly, most accounts are small, but these addresses represent only 4% of the total WETH locked. At the same time, one address holds 15% of the locked value and the other holds nearly 8%. These two accounts hold nearly a quarter of the collateral.
