💡 If you haven't already be sure to check out Merge Buenos Aires, which takes place March 24-26 in the Argentine capital. The conference is an exciting opportunity to connect Europe and Latin America through Web3 and will provide a great pulse check on crypto adoption in the region. I'll be attending and I hope to see some of you there as well

Olá pessoal and happy Carnaval!
For today’s episode we’ve assembled several key players from Drex ecosystem to discuss a new report from the Central Bank of Brazil analyzing Phase 1 of the Drex pilot.
Marcos Viriato, CEO of Parfin — whose Rayls solution is being used extensively in the testing
Leandro Sciammarella Pereira, Technology Lead at Núclea Digital Asset, which leads one of the 16 consortia participating in the pilot
Ricardo Paixão, technical adviser to the Brazilian Congress and coordinator of CRIA who has been involved in the Drex project since its very early days
For those catching up, Drex is the ambitious CBDC/tokenization project that tries to thread the needle between the traditional wholesale and retail CBDC models. It’s the capstone project of the Brazilian Central Bank’s innovation agenda, which has successfully rolled out Pix and Open Finance over the last five years.
Phase 1 of the Drex pilot concluded last June, and Brazil’s Central Bank released last week a 70+ page technical report last week highlighting the successes and blockers while noting that a “major adaptation” will be needed for Drex to become a core piece of Brazil’s financial infrastructure.
This conversation with Marcos, Leandro and Ricardo addresses the report’s findings and addresses some of the negative reactions and FUD that circulated on social media and Whatsapp groups following the report’s publication.
They argue that the findings weren't surprising or necessarily negative but rather confirmed technical challenges that the bank has been broadcasting publicly for some time now — specifically that of balancing the “DREX Trilemma” of:
Balancing privacy (shielding transaction details)
Maintaining composability (allowing smart contracts to interact)
Enabling programmability (supporting DeFi innovation)
Managing expectations for a project of this size and scope is a critical, and it’s important to remember that this was a pilot that where the objective is to test, iterate, learn and improve.
While the first phase of the pilot focused on testing privacy solutions, Phase 2 — now ongoing — is addressing the remaining challenges along with scalability concerns.
The Central Bank's decision not to test additional use cases beyond the 13 already selected was viewed as pragmatic rather than problematic. With the existing use cases already covering tokenized real estate, credit receivables, and other key applications, expanding further would stretch limited resources.
A significant challenge highlighted during the discussion was integration with legacy systems. As Leandro explained, connecting blockchain infrastructure with traditional banking systems requires building components "from scratch" - a complex undertaking beyond the technical aspects of the blockchain itself.
The experts remained optimistic about the growth of tokenization in Brazil regardless of Drex’s timeline.
"Companies are already tokenizing assets and doing business," noted Ricardo, pointing to ongoing market developments that will continue with or without the central bank infrastructure.
Marcos concluded with a call for resilience:
"The Central Bank is at the forefront of this innovation. Don't lose it... this infrastructure will be required for our nation."
Have a great day everyone!
