Common Questions

What is Ink Pay?

Ink Pay is a DApp (decentralized application) that allows you to buy and sell on any platform or marketplace and earn public reputation that you can take wherever you sell. As a buyer, Ink Pay also lets you view the transaction history and reputation of any seller via their Ethereum address or QR code. This helps you make sure they're trustworthy before you buy.

How are payments made?

Payments can be made in either XNK (pronounced "Ink"), ETH, or Dai. The currency that a buyer uses to pay is also the currency that the seller receives.

XNK is the native cryptocurrency used by Ink Protocol, ETH is the underlying token that powers the Ethereum blockchain, and Dai is an ERC20 token designed to be pegged to the US Dollar.

What is Ink Protocol?

Ink Protocol is a decentralized reputation and payment system powered by the Ethereum blockchain and its native ERC20 utility token called Ink Protocol Token (XNK). It is designed specifically for P2P marketplace transactions where trust between the buyer and seller may be limited. Ink greatly enhances the buying/selling process by helping users safely send and receive payments in P2P marketplaces while earning publicly viewable reputation.
