Data Security


To talk about security and good practices we must first understand what blockchain is. In a well-didactic way, blockchain is like a notebook with a number of infinite pages. On each page of this notebook are recorded all the entries and outflows of money over a certain period and the balance of who paid and who received it. In addition, each page carries a fingerprint. Suppose each page records all transactions performed over an entire day. The next day, therefore, the transactions will be recorded on a new page. But in addition to these transactions, the new page will have the fingerprint of the previous one, in addition to having its own fingerprint. Thus, each page of the notebook depends on the previous one to exist.

It turns out that if someone changes any records on one of these pages, that fingerprint changes. So, if someone maliciously goes on the previous page and tries to change some transaction, the fingerprint will change and the next page will not recognize it. This page will then no longer be worth it. To change a page, all of the following ones would have to be changed, which makes any fraud virtually impossible.


There are a number of security measures that a crypto firm can adopt. The first step is to work with full transparency in the management of resources and accesses. In the case of Transfero Swiss AG, for example, all five executive partners have access to the keys of the company’s cold and hot wallets. In addition, two directors and/or international partners are not allowed to take the same flight.

For digital asset transfers, Transfero uses digital wallets with multiple signatures, in which verification of at least three directors is required to validate any transaction.

Transfero Swiss’ security system has strict authentication controls and authorization processes to ensure that only the appropriate staff can have access to and visibility of the necessary information.

Information protection is guaranteed in our suppliers’ infrastructure configured with high security standards.



The enactment of the Brazilian General Data Protection Law (“LGPD”) in 2018, strongly inspired by the European General Data Protection Regulation (“GDPR”), unveils a new scenario in the area of privacy and data protection. In this sense, Transfero Swiss AG’s Privacy Policy reflects the best practices for the collection and storage of personal data, allowing user privacy to be respected while global regulatory standards such as Anti-Money Laundering (AML) policies, Know-Your-Customer (KYC), and Counter Terrorist Financing (CTF) are strictly complied with.
