BankDex is a decentralised cryptocurrency exchange built on an innovative and ground-breaking technology that facilitates inter-blockchain transfer of crypto assets. At present, traders are forced to use centralised exchanges where traders share their control on the assets which creates a huge risk for them. However, BankDex is the first decentralised exchange that solves the transaction problem of cross-chain transfer between dierent blockchain accounts in a distributed ledger network. On BankDex traders will be able to trade BITCOIN, ETHEREUM, AND other ERC20 TOKENS.
