ChainCatcher news, at the "Bridge Web3" event hosted by the DeFi platform ArrayFi, ArrayFi CMO Jim Andy announced that ArrayFi officially launched on May 27.The core module of ArrayFi is a currency system supported by AI algorithms. Users who stake ARA will lend stablecoin USDR, with a value ratio of 4:1 between the two. 90% of the staked funds will go into the secure vault of ArrayGo (ArrayFi's self-developed AI algorithm) to maintain the bottom price of ARA, while the remaining 10% will be injected into the LP pool for market price discovery. ARA adopts a fair issuance mechanism, with no seed or private placement rounds, and no upper limit on total supply. The use cases for USDR include applications such as ArrayFi's partner social e-commerce Liza, its lucky spin game, and prediction platforms. (source link)
