Financial news from TiemGiamGia, Mantle in the latest quarterly newsletter revealed two important releases: the Mantle Banking crypto banking app and the Mantle Index Four (MI4) tokenized fund. Mantle Banking will integrate the management of fiat and crypto assets, allowing users to spend, save, and invest in one account, while also supporting the direct tokenization of salary into stablecoins, combined with a global virtual payment card, creating a seamless bridge between TradFi and DeFi. MI4 is a tokenized fund backed by a $400 million investment from Mantle Treasury, positioned as the "crypto version of the S&P 500", providing effective crypto Beta exposure, and will eventually be traded in tokenized form on the Mantle Network. Mantle stated that these products will drive the development of the ecosystem and invite $MNT holders to participate in the design of functionality and product governance.
