Business challenge
Digital assets have become an important part of the global economy. Yet, they still oftentimes function in the gray zone due to the lack of convenient tools within the legal field. Indeed, authorities around the world have been grappling with the question of how to respond to cryptocurrencies.
In LATAM, regulatory approaches varied by country:
- Brazil and Chile advanced licensing/perimeter rules
- Mexico imposed strict limits on regulated financial institutions’ virtual-asset activity
- Colombia relied more on pilots/sandbox initiatives and proposed legislation
This encouraged our client, a fintech company, to leverage the situation in the region. The idea was to develop an efficient and secure solution, which would allow the users to make cryptocurrency transactions legally and transparently.

- Develop a full-featured backend with banking and payment integrations

Focus on compliance with the regulatory context in LATAM
Our dedicated team treated compliance as a core design principle from day one. The cryptocurrency exchange is aligned with:
- Local VASP registration and reporting requirements in key LATAM markets
- FATF Travel Rule-ready data exchange flows where required by local regulation and counterparties
- Country-specific AML/CTF requirements and supervisory guidance (Brazil’s AML/CTF obligations for VASPs under the post–Virtual Assets Act framework; Mexico’s constraints and authorization model for regulated entities’ virtual-asset operations)
- Data protection controls adjusted to national privacy laws in each operating country (data minimization, retention, access control, audit trails, breach handling)
This approach enabled the client’s solution to scale across multiple LATAM countries with minimal legal friction.
Ernst & Young Audit
An independent audit by Ernst & Young confirmed that the exchange’s control environment, covering security, privacy, and compliance, met the agreed criteria. This included a thorough assessment of AML/CTF controls, which were found to align with FATF standards where applicable.
