Hi @Tina
Thank you very much for your feedback.

Indeed, the page and the application were developed in Spanish because the main market is Latin American, starting with Venezuela, but taking care of your suggestion, we have started today the translation to have the WEB page in two languages (Spanish and English) to next week, as for the application, we can have it in both languages in the next 3-4 weeks afterwards because in the calendar we have other priority tasks for our pilot test.

Regarding the budget, tomorrow (06/12) I will send the most detailed information as you are requesting it.

Again I appreciate your interest

@sgcvzla.chain seems very interesting specially for Southamerica were people really need alternatives to volatile FIAT currencies. One question: the value in this cards(prepaid, gift…) will be in AE or in what?


Hi @Manel , thanks for your feedback
Indeed, the Latin American market, especially the Venezuelan one, needs alternatives to cash and FIAT currencies so that the economy can flow more freely.

Currently the cards are sold in Bolivars and Dollars (FIAT), we hope with this project to start operating in AE in the shortest possible time.


that would be amazing! good job!

AE, what’s the point of your life?

a truly usable public Blockchain for decentralized applications with no scalabilitiy limits?


Sorry @beijing, I don’t undersatnd your question?

The Cash Flag Team participated in the last hackathon we did in Venezuela, I know they are commited to deliver the final product . They have a well organized team of developers and I hope their product helps grow AE adoption in Venezuela.


That’s right @jcdelpino , our goal is to contribute to adoption in Venezuela and Latin America while offering solutions that help Small Bussines grow

@sgcvzla.chain has been working this project for more than a year, and has become a very experienced Aeternity developer, Cash-Flag join blockchain and real use case for many. I think it is important to support efforts like this one.


The idea is perfect and i see no issue with it at all. Also have no reason to doubt your ability to do the dapp and make it work. The two problems or hurdles i see is getting vendors on board, that is always an issue.

The second problem is the get it into ae currency. As i know most people know, trust and use bitcoin, so adoption of an unknown currency is slow and tedious.

We both know ae, but how many people in Venezuela knows ae and are there exchanges where they can buy it?


Thanks @Whyarewehere42.chain,

Indeed, you have identified a couple of risks of the project, but I tell you that we have a commercial strategy to attract businesses with a small own sales force and a structure of strategic allies that allows us to cover the largest possible territory and grow exponentially both in quantity of users as in consumption.

In addition, as a brand, we will carry out strategic marketing actions to promote the platform, we have strategies for the point of sale or affiliated commerce, they will receive financial incentives for attracting and consuming users on the platform.

The combination of our work as a brand, the sales force, the strategic allies and the businesses in a coordinated, oriented and controlled manner will give us the expected growth.

In response to the second problem, I tell you that we plan to use AE as the base currency for the platform, when affiliating businesses, an account will be created in AE where they will have to deposit and maintain a positive balance sufficient to pay the commissions, in this sense, each new Commerce will be a new user of AE and as its business grows, transactions in AE will grow.

Generally speaking, in our country the adoption of cryptocurrencies is growing, there are many users and formal and informal exchange platforms, in addition to several payment processors, for example: Cryptoway, Basichange, All authorized exchanges, Panda, Cryptobuyer, Pundix , mPandco, Localbitcoins, Swap4me, Coincola, Ccoins

From here we want to start the business and then expand it to other countries in Latin America.

I must clarify that Cash-Flag does not intend nor is it capable of unilaterally facing the challenge of adopting AE in Venezuela and Latin America, but we can provide a reliable solution with a clear growth strategy for the community.

It is for this reason that we need support to consolidate this platform in this region.


The app has started it first trial with real use case.


Hello @ivanubikalo.chain , that’s right, this weekend we gave induction to the staff of our first affiliated store and we are already coordinating the induction to two more stores that will be done later this week online.
We have not been able to generate more transactions because a radical 7-day quarantine period began for COVID 19, but we will resume from next Monday 07/13
