Project Overview:

• Buyer can purchase NFTs by paying directly with credit card at dApps as easily as Amazon online shopping. No longer need to prepare the specific payment tokens to purchase NFTs in advance.
• Sellers(dApps) can be easily integrated with just a single API and be provided optimal settlement like Stripe. There is no need to change the dApps' existing custom smart contracts.

Problem Statement:

• For buyers, it is too inconvenient to purchase NFTs in the SmartContract-based dApps because dedicated payment tokens are required for the buyers to pay with.
• Sellers(dApps) are facing the dilemma between demand of their own base token and its payment usability.

Solution:

LINKA Pay, the fiat payment oracle system, provides a specific smart contract that instantly interconnects fiat payments and token payments

1. Once a buyer places an order NFTs, LINKA Pay processes buyer’s credit/debit card payment and calls dApp’s smart contract on behalf of the buyer.
2. With LINKA Pay, buyers can pay with credit/debit cards and dApps can be settled with their own payment tokens.
3. For processing, the liquidity of payment tokens is provided by the third parties(e.g. liquidity providers)
4. LINKA Pay fully supports any dApps’ smart contract, mainnet without any code changes.
