This was the part of Wirecard hackathon 2019. Detail can be found at this link. I am putting it here to leverage it to wider audience as part of Open Source Community.

Make your idea visual

Current payment infrastructure happens via two methods.

  1. Through Banks: Banks does cross border payment on decade old infrastructure.
  2. Mastercard/Visa and few central companies They have legacy and monopoly in payment industry which is highly defense industry in itself.

Using DLT and smart contract Wirecard can reduce the cost along with that automate the whole process. This will promote the cashless transfer of money movement with proper auditing.

Wirecard will have their one common relayer built on blockchain and seperate exchange p2p platform for each country.

Let’s consider the case for two countries Indonesia and Germany. There are lots of aspiring students who have to transfer Indonesian local money to Germany (Euro) for their studies. And on the other hand, there are lots of Indonesian people working in Germany who wants to transfer money to their parents. There is a transfer of money where multiple parties are involved like Western Union, federal bank and various other local players. To run all these infrastructures there’s a huge volume of money and time involved.

There will be a dashboard where buyer and seller of particular currency will be listed. Trade will be automated by the price quoted by user and wirecard.

If there is liquidity fall then Wirecard relayer will be used. Else, everything will be settled within the country.


There is always a movement from one country to another country. While doing the money transfer there’s time and cost involved. Settlement and clearance are still done on decades-old infrastructure. Please, read the full thread. (https://twitter.com/a4nkit/sta...) . Multiple parties are involved and in case of an issue, no one wants to be accountable…
