The Wavefield DAO will join forces with mainstream institutions in the blockchain industry to launch USDD (Decentralized USD), which will not rely on centralized institutions for redemption management and reserves, but will be completely decentralized on the chain and issued with a decentralized anchor peg to TRX, the standard currency on the chain, so that when the price of USDD is less than 1 USD, users and arbitrageurs will send 1 USDD to the system in a decentralized form and receive 1 USD worth of TRX. When the price of USDD is greater than 1 USD, users and arbitrageurs send TRX worth 1 USD to the system in a decentralised form and receive 1 USDD. The USDD protocol maintains the market rate of USDD at the target 1:1 rate in a decentralised form, regardless of market conditions. With the USDD protocol, a modern financial system based on blockchain technology will be created.
