Brazil DREX Timeline 2024-2026

Wiki route

This entry sits under fintech index and is the Brazil-specific deep dive that the regional latin-america-cbdc-stablecoin-dollarization entry references for DREX mechanics and Pix interplay. Read it alongside the multi-tier CBDC architecture framework at cbdc-multi-tier-architecture-overview, the tokenized-deposit institutional thesis at institutional-stablecoin-deposit-token-thesis, and the BIS cross-CBDC interoperability surfaces at mbridge-bis-multi-cbdc-overview and bis-project-agora-overview for comparative context.

[!info] TL;DR DREX is the operational name of Brazil’s CBDC project, run by the Banco Central do Brasil (BCB) since 2020. As of 2026-05 it is in Pilot 2 (expanded multi-asset, multi-participant), with Pilot 1 (closed-loop reserve-transfer + DvP) completed 2024. The platform runs on a Hyperledger Besu permissioned network with a two-tier architecture: BCB issues wholesale CBDC to licensed financial institutions; those institutions issue tokenized deposits to end customers. DREX is explicitly not a retail CBDC token; the retail-facing layer is tokenized commercial-bank deposits that interoperate with the Pix instant-payment rail. Programmable-money use cases (DvP, escrow, conditional payments, smart-contract-mediated trade finance) are the catalyst for adoption. Competing on the same retail surface is a small but growing independent BRL-pegged stablecoin segment (BRLA Digital, Mercado Bitcoin MBRL) running outside the DREX perimeter.

DREX in one paragraph

DREX is a two-tier tokenization platform: BCB issues a wholesale CBDC token to licensed banks and licensed payment institutions; those institutions issue tokenized deposits (denominated in BRL) to their customers. End users transact in tokenized deposits, not in BCB-issued tokens. The architecture is closer to the Japanese trust-type EPI model (see jp-trust-type-sc-architecture and japan-epi-three-types-overview) and to the Hong Kong tokenized-deposit pilots than to a single-token retail CBDC like the Bahamas Sand Dollar.

Origin and naming

2020-08: BCB launched a CBDC study and signaled intent to issue Real Digital.
2022: Working groups across BCB technical staff, academia, and industry produced the initial requirements.
2023-03: The platform was officially named DREX (Digital REal eXchange / Digital Real). BCB published the platform-design papers.
2023-05: BCB selected the technology stack: Hyperledger Besu, an enterprise Ethereum-compatible permissioned blockchain implementation.
2023-Q4: Onboarding of Pilot 1 participants began.
2024: Pilot 1 closed-loop testing.
2025: Pilot 1 concluded; Pilot 2 design and onboarding.
2026: Pilot 2 in progress with expanded participants and asset classes.

Two-tier issuance model

Layer	Issuer	Token	Holder
Wholesale (Tier 1)	BCB	DREX wholesale CBDC	Licensed financial institutions
Retail (Tier 2)	Licensed institution	Tokenized deposit (denominated in BRL)	End customers (businesses + individuals)

End users never hold the BCB-issued token directly. They hold tokenized commercial-bank deposits redeemable 1:1 against the wholesale CBDC held by their bank at BCB. This is the same architectural pattern surveyed in cbdc-multi-tier-architecture-three-paradigms and the policy-tradeoff analysis in cbdc-multi-tier-architecture-tradeoffs.

Technology stack

Network: Hyperledger Besu (permissioned, EVM-compatible).
Consensus: IBFT 2.0 (Istanbul Byzantine Fault Tolerance) variant suitable for known-validator permissioned networks.
Privacy: Privacy-preserving mechanisms tested across Pilot 1 (encrypted balances and selective disclosure variants from Aztec, Anonymous Zether, and similar primitives) — a known design challenge given the public-by-default nature of EVM.
Smart contracts: Solidity-compatible; permissioned deployment by approved participants.
Identity / KYC: Tied to BCB participant licensing; on-chain identity links to participants’ off-chain KYC databases.

Pilot 1 (2024)

Scope: Closed-loop test among a curated set of participants. Asset classes:

Wholesale CBDC (BCB-issued).
Tokenized deposits issued by participating banks.
Tokenized federal public debt (Treasury bonds, in collaboration with the Tesouro Nacional).
Delivery-versus-Payment (DvP) test cases.

Participants (publicly named in BCB communications across 2023-2024): a consortium that included major Brazilian banks (Itaú, Bradesco, BTG Pactual, Santander Brasil, Banco do Brasil, Caixa Econômica Federal), fintechs (Nubank, Inter), and payment-system entities, along with BCB and Tesouro Nacional.

Outcomes (per BCB public communications):

DvP across tokenized deposits and tokenized federal debt validated.
Smart-contract-mediated escrow and conditional-payment scenarios validated.
Privacy architecture identified as the central unresolved challenge — Pilot 1 made clear that EVM transparency requires substantive privacy-overlay engineering before a retail rollout is responsible.

Pilot 2 (2025-2026)

Expansion axes:

Broader participant set (more banks, payment institutions, fintechs).
More asset classes (additional tokenized assets including private securities and trade receivables).
More complex use cases (cross-asset DvP, escrow, programmable-payment automation).
Continued privacy-architecture work.

Status as of 2026-05: Pilot 2 is in progress, with no announced production-launch date. BCB has consistently emphasized that the platform will not move to production until privacy challenges are resolved at a level acceptable for retail customer data.

Pix integration · the structural anchor

Pix is BCB’s instant payment system launched 2020-11, , used by hundreds of millions of accounts, processing hundreds of millions of transactions per day. Pix is the single most important constraint on DREX adoption because Pix already delivers:

Instant 24/7 settlement.
Zero or near-zero retail cost.
Universal merchant acceptance via QR code.
Bank and fintech parity.

A retail CBDC competing with Pix on these axes has no value proposition unless it adds programmability, DvP, or cross-asset settlement. This is exactly why DREX is explicitly not a retail-CBDC-competing-with-Pix project — instead, DREX is designed to:

Sit upstream of Pix as a wholesale reserve-transfer rail.
Add programmability that Pix does not natively support (smart-contract conditions, DvP, escrow).
Interoperate with Pix for the retail leg — a DREX-mediated trade can settle the cash leg via Pix or via tokenized-deposit transfer on DREX itself.

The competitive baseline that Pix sets for any Brazilian-stablecoin project is the same dynamic as QRIS in Indonesia (see indonesia-ovo-stablecoin-route and southeast-asia-stablecoin-regulatory-landscape) and CoDi in Mexico (see latin-america-cbdc-stablecoin-dollarization).

Programmable-money use cases targeted

Use case	Description	Why DREX helps
DvP for tokenized federal debt	Tesouro Nacional bonds tokenized; cash leg in tokenized deposit	Atomic settlement vs current T+1/T+2
Escrow for real estate	Funds locked in smart contract pending title transfer	Removes intermediary; programmable conditions
Trade finance	Letter of credit + invoice + payment automated	Reduces document-handling cost and dispute window
Conditional payment	Payment released on oracle-verified event	New use case not feasible on Pix
Payroll automation	Streamed or scheduled payment	New use case
Cross-asset DvP	Tokenized commodity vs tokenized deposit	New use case

The pattern matches the institutional / wholesale value proposition that institutional-stablecoin-deposit-token-thesis argues for and the broader B2B stablecoin growth trajectory in stablecoin-crossborder-b2b-growth.

Competing private BRL stablecoin segment

DREX exists alongside a smaller but growing independent BRL-pegged stablecoin segment that runs outside the DREX perimeter:

BRLA Digital

BRL-pegged stablecoin issued by BRLA Digital, with Brazilian banking partners.
Targets B2B settlement and crypto-native retail flow.
Operates as a regulated entity under BCB oversight via the Marco Legal das Criptomoedas (Law 14.478 / 2022) framework.
Cross-chain footprint includes Ethereum, Polygon, and other EVM-compatible chains.

Mercado Bitcoin MBRL

Mercado Bitcoin (MB), Brazil’s largest digital-asset venue, has piloted a BRL-pegged token (often referenced as MBRL) leveraging BRLA infrastructure.
Designed to support retail trading-pair settlement and B2B onramp / offramp.

Why private BRL stablecoins coexist with DREX

Axis	DREX tokenized deposit	Private BRL stablecoin
Issuer	Licensed bank	Non-bank or hybrid issuer
Network	Permissioned Hyperledger Besu	Public EVM chains
Interoperability with DeFi	None (permissioned)	Yes
Cross-border integration	Via BCB and BIS frameworks	Via public chain liquidity
Programmable-money depth	Strong (smart contracts)	Strong (smart contracts)
Retail UX	Tied to participating bank app	Web3 wallet + crypto-native apps

The two rails serve different user populations. DREX wins regulated wholesale and bank-customer programmable-payment use cases. Private BRL stablecoins win DeFi-native and crypto-native use cases. The economic similarity to the issuer-distributor split in issuer-distributor-incentive-realignment-50-50-model is structural.

Cross-CBDC interoperability surfaces

Brazil’s BCB participates in multiple cross-CBDC initiatives that affect DREX’s long-run interoperability story:

BIS Innovation Hub Eurosystem Centre and Americas Centre — Brazilian engagement in standards-setting work.
Project mBridge (PBoC, HKMA, BoT, CBUAE, SAMA earlier; BoT withdrew 2024) — see mbridge-bis-multi-cbdc-overview. Brazil is not a full mBridge participant, but observes the architecture.
Project Agora (BIS + private banks, multi-CBDC + tokenized commercial bank money) — see bis-project-agora-overview and bis-project-agora-vs-mbridge. Brazil’s participation level has been signalled at observational; full integration would shape DREX’s cross-border posture.
Project Ensemble (HKMA + private banks, tokenized money + tokenized assets) — see bis-project-ensemble-overview and bis-project-ensemble-vs-mbridge-dual-track. DREX’s design pattern is closer to Ensemble’s tokenized-deposit architecture than to mBridge’s wholesale-CBDC-only approach.
Project Nexus (BIS-led instant payment interlink) — extension to Latin America corridors would directly affect Pix cross-border use cases.
