- Privacy failures in Phase 1 highlighted potential security vulnerabilities in digital asset rollouts.
- Global regulatory hesitancies stall CBDCs, with 31% of projects delayed by governance issues.
The Central Bank of Brazil (BCB) has released a report detailing the first testing phase for Drex, its digital asset infrastructure project.
The document confirms unresolved privacy concerns, raising questions about the project’s readiness. The BCB stated that use cases submitted by the public by the 24th of November would not be tested.
This report comes amid regulatory uncertainty delaying CBDC projects globally.
A recent study by the Official Monetary and Financial Institutions Forum (OMFIF) found that 31% of central banks have delayed CBDC timelines due to governance issues, regulatory concerns, and competing economic priorities.

While Drex is not technically classified as a CBDC, its development aligns with a broader global debate on digital assets and financial oversight.
Privacy: The Achilles’s heel of Drex?
A key finding in BCB’s report is that Drex’s design has unresolved privacy concerns.
The central bank has yet to provide a solution to data protection challenges, which has been a contentious issue in CBDC discussions worldwide.
Will ‘using Drex’ be like ‘making a pix’?
This challenge is significant in Brazil, where stablecoins dominate the crypto landscape. Central Bank President Gabriel Galipolo stated that 90% of crypto transactions are through stablecoins, primarily for payments.
This raises an important question: Will Drex serve as a regulated, compliant alternative to stablecoins for digital payments? Or will its privacy limitations and regulatory hurdles push users to rely on existing stablecoins?
Officials highlighted similarities between Drex and Pix, Brazil’s instant payment system introduced in 2020. Maurício Moura, BCB’s Deputy Governor for institutional elations, citizenship, and conduct supervision, emphasized the bank’s ambition for Drex.
He stated,
“Since its launch, Pix was soon incorporated as a common word in everyday life. Today, we all talk about ‘making a Pix’. Soon, we will also say ‘using Drex’.”
Why won’t new use cases be tested in phase 2?
Two primary reasons why the use cases submitted by the 24th of November will not be tested are unresolved privacy concerns and redundancy in proposals.
Privacy and security remain the central bank’s top priorities. Tested privacy solutions failed to meet Brazil’s strict banking secrecy laws. Expanding Drex without addressing these concerns could introduce regulatory risks and security vulnerabilities.
Of the 101 submitted proposals, around 50 met the basic criteria for testing. However, most were too similar to existing pilot programs.
Many focused on tokenized assets and payments, areas already explored in Phase 1. Rather than testing redundant ideas, the central bank will refine the current pilot for legal and technical readiness.
Brazil is also learning from previous CBDC challenges. Nigeria’s eNaira and the Bahamas’ Sand Dollar struggled due to rushed implementations. Both projects launched before solving key adoption and security issues, leading to low usage.
Global regulatory pressures and delayed CBDC plans
The challenges outlined in BCB’s report reflect broader global trends in digital asset regulation.
The OMFIF study found that regulatory uncertainty is a major hurdle for central banks worldwide. While privacy remains a technical issue for some projects, governance structures, and compliance frameworks are also delaying CBDC timelines.
Despite its challenges, Brazil remains a leader in crypto adoption.
Between July 2023 and June 2024, Brazilian users deposited nearly $90 billion in digital assets, making the country the second-largest crypto market in Latin America after Argentina, according to a Chainalysis report.
The increasing integration of tokenized financial instruments and stablecoins into the national economy places additional pressure on regulators to balance innovation with oversight.
What’s next for Drex?
While BCB has not provided a definitive roadmap for resolving Drex’s privacy concerns, the project remains a priority.
The next phase of development will likely focus on regulatory clarity, technical refinements, and stakeholder engagement.
