Wu Wu said that according to Tron DAO Reserve data, about 12,000 BTC used as USDD reserves recently have been removed, and the address used to reserve these BTC: 1KVpuC…ni7pPj is no longer displayed in the reserve address list. On-chain data shows that the original USDD reserve address: 1KVpuC…ni7pPj transferred 3.5k BTC (worth about $236 million) between 2:18-3:43 UTC+8 on August 19, and then all flowed into other HTX addresses marked by Arkham. The current supply of USDD is about 745 million, with a collateral value of $1.723 billion, but about 98.8% of it is supported by 10.93 million TRX (1.703 billion). It is worth noting that neither TRON DAO nor USDD and other related Twitter accounts informed in advance of the decision to remove BTC reserves from USDD. Justin Sun later said that the USDD mechanism is similar to MakerDAO DAI, and claimed that TRON DAO reserve plans to spend time upgrading USDD in the future.
