FinNexus is the new open finance protocol being built on the Wanchain blockchain. It is a hub for connecting different decentralized ledgers to each other and users, and also for connecting with traditional finance applications. The first iteration of FinNexus will be a marketplace for hybrid decentralized/traditional financial products. Our first three products include Wandora Box, a fun price prediction game in Wan Wallet; a cross-chain tokenization platform for real world digital assets including currently on WAN and XRP; and a fully decentralized bitcoin options minting protocol.
