The Central Bank of Brazil (BCB) has officially launched the second phase of its Central Bank Digital Currency (CBDC) pilot program, Drex. This new stage introduces expanded opportunities for financial institutions to innovate through asset tokenization while placing a strong emphasis on privacy-preserving technologies such as zero-knowledge proofs (ZKPs). The move underscores Brazil’s strategic push toward building a modern, secure, and efficient digital financial infrastructure.
With this announcement, the BCB has opened a public call for proposals, inviting qualified financial institutions and consortia to submit innovative use cases that align with the nation's vision for a tokenized economy. The goal is clear: lay the groundwork for a robust, scalable, and interoperable tokenization ecosystem within Brazil’s financial system.
First-Phase Pilot Overview: Laying the Foundation
The initial phase of the Drex pilot involved 16 participating consortia—most led by major banks—exploring the feasibility of tokenizing traditional financial instruments and assets on decentralized networks. These early experiments have yielded 13 confirmed test cases, demonstrating the versatility and potential of blockchain-based finance in real-world applications.
Key areas explored in Phase One include:
- Tokenization of bank deposits – Enabling digital representation of fiat balances for faster settlement.
- Bond tokenization – Digitizing corporate and government bonds to streamline issuance and trading.
- Accounts receivable distribution – Automating payment flows using smart contracts.
- Mortgage loans from the National Development Bank – Testing digitized lending processes.
- Secured loans backed by government bonds – Exploring collateralized credit mechanisms.
- Trade finance optimization – Reducing friction in cross-border transactions.
- Foreign exchange market efficiency – Enhancing liquidity and settlement speed.
- Public debt liquidity pools – Creating dynamic markets for government securities.
- Transactions involving CCBs – Tokenizing Cédulas de Crédito Bancário, a unique Brazilian financial instrument where businesses issue secured debt notes to banks with flexible terms.
- Agribusiness asset tokenization – Representing farmland, machinery, inventory, and crops as digital assets for trading.
- Asset registration on public networks – Recording ownership of real estate, intellectual property, and financial instruments on decentralized ledgers.
- Multi-asset decentralized trading – Facilitating peer-to-peer exchanges of vehicles, carbon credits, bonds, and real estate.
These pilot projects have provided critical insights into technical scalability, regulatory alignment, and user adoption challenges—insights now shaping the evolution of Phase Two.
Phase Two Goals: Scaling Participation and Strengthening Privacy
The second phase of the Drex pilot aims to broaden participation beyond the current 16 consortia, encouraging more institutions to contribute innovative solutions. The focus shifts toward testing more complex, interconnected scenarios that reflect real-world financial workflows.
A major priority in this phase is enhancing data privacy. While blockchain offers transparency and immutability, it also raises concerns about sensitive financial data exposure. To address this, participating entities must continue developing and testing advanced privacy technologies, including:
- Zether – A privacy protocol enabling confidential payments on public blockchains.
- Starlight – A framework for private smart contract execution.
- Rayls – A privacy layer designed for enterprise-grade confidentiality.
- ZKP Nova – An implementation leveraging zero-knowledge proofs to validate transactions without revealing underlying details.
These tools allow transaction verification without exposing amounts, parties involved, or asset types—ensuring compliance with data protection laws like Brazil’s LGPD (General Data Protection Law) while maintaining auditability for regulators.
The Committee for Execution and Governance (CEG) will oversee the evaluation process, accepting proposals between October 14 and November 29. Each submission must detail the technical design, operational feasibility, and alignment with national financial objectives. Selected projects will undergo rigorous testing under controlled conditions before any potential public rollout.
This structured approach reflects Brazil’s balanced strategy: fostering innovation while prioritizing security, inclusivity, and regulatory coherence.
Why Asset Tokenization Matters for Brazil’s Financial Future
Asset tokenization—the process of converting rights to an asset into a digital token on a blockchain—holds transformative potential for Brazil’s economy. It enables fractional ownership, increases market liquidity, reduces settlement times from days to seconds, and lowers transaction costs across sectors.
For example, small investors could buy fractions of high-value properties or agricultural land. Companies can unlock capital by tokenizing future revenue streams or equipment. Governments can improve transparency in public finance by issuing digital treasury bonds.
Moreover, integrating ZK-based privacy solutions ensures that these benefits don’t come at the cost of user confidentiality. By embedding privacy into the architecture rather than treating it as an afterthought, Brazil is setting a precedent for responsible digital currency development.

Frequently Asked Questions (FAQ)
Q: What is Drex?
A: Drex is Brazil’s central bank digital currency (CBDC) pilot program aimed at exploring the use of digital real (BRL) on blockchain networks for secure and efficient transactions.
Q: How does Drex differ from cryptocurrencies like Bitcoin?
A: Unlike decentralized cryptocurrencies, Drex is issued and regulated by the Central Bank of Brazil. It represents a digital form of sovereign currency with full legal tender status, designed for stability and integration into the existing financial system.
Q: Is Drex available for public use yet?
A: No. Drex remains in the pilot phase and is currently limited to testing by authorized financial institutions. There is no official timeline for public release.
Q: What role do ZK proofs play in Drex?
A: Zero-knowledge proofs (ZKPs) enable transaction validation without revealing sensitive data such as amount or participant identities. This ensures both transparency for regulators and privacy for users.
Q: Can foreign companies participate in the Drex pilot?
A: Participation is open to entities that meet BCB’s regulatory and operational requirements. While primarily focused on domestic institutions, international firms may join through partnerships with local entities.
Q: Will Drex replace cash?
A: The BCB has stated that Drex is intended to complement—not replace—physical currency. Cash will remain a legal payment method alongside digital options.
The Road Ahead: Building a Tokenized Economy
As Brazil advances into Phase Two of the Drex initiative, it positions itself as a leader in emerging market fintech innovation. By combining asset tokenization with strong privacy safeguards, the country is crafting a model that other nations may follow.
Future developments may include interoperability with other CBDCs, integration with decentralized finance (DeFi) protocols under regulated frameworks, and broader inclusion of non-financial assets like carbon credits or renewable energy certificates.
With continued investment in infrastructure, regulation, and public-private collaboration, Brazil’s journey toward a fully tokenized financial ecosystem is well underway.
