About

Swipe is a multi-asset digital wallet application and Visa debit card that enables users buy, sell, and spend various cryptocurrencies. Swipe utilizes the Ethereum blockchain to operate the Swipe Network. Swipe uses a two-layer approach for its users to combine off-chain and on-chain function on its platform which is powered by the Swipe Token (SXP). For off-chain usage, supported cryptocurrencies can be instantly converted to fiat and used on point of sale. When the Swipe Network is activated in the platform, users receive a smart contract wallet which uses SXP directly on-chain to perform its functions. As functions are being called on the Swipe Network, 80% of those SXP fees are automatically burned creating a deflationary supply model. Users may use SXP today in the following ways: • Currency: When users select SXP as a funding source it may be used on the Swipe Visa card to be converted to Euros and spent at millions of merchants. • Staking: To receive the higher tier cards, discounts, and rewards enhancements, users must stake SXP which is locked on-chain. • Fees: If the Swipe Network is activated within the platform, users are able to use SXP towards all fees on the platform such as conversion fee and withdrawal fees
