TORONTO, Oct. 5, 2017- STACK introduces instant cryptocurrency payments at point of sale with the STK token. Built on the Ethereum blockchain as an ERC20 token, the STK token will enable users to transact with cryptocurrency in mainstream markets and at brick-and-mortar stores without the cumbersome exchange process typical of most cryptocurrencies. A current lack of merchant acceptance of cryptocurrencies at points of sale and online means that consumers are required to exchange cryptocurrencies into local currency in order to make everyday purchases. And settlement times for bitcoin and ether are too long for real-time transactions. STK tokens will allow users to access an immediate exchange so that cryptocurrency can be used for daily transactions online and in-store.
