Brazil Drex × Mexico CoDi / MXNB · public and private digital-money routes 2026

TL;DR

Brazil and Mexico do not follow the same digital-money route. Brazil’s Drex is a regulated-intermediary DLT platform developed by Banco Central do Brasil (BCB); as of 2026-07-30, the official page says that pilot user transactions are simulated and marks Phase 2 as concluded. Mexico’s CoDi is a QR / NFC payment service operated by Banxico on SPEI, not a CBDC. On the private side, Juno, a Bitso group company, issues MXNB (MXN, Arbitrum) and BRL1 (BRL, Polygon). This revision removes the previous claims about joint issuance by Mercado Bitcoin / M0 and the invented circulating supply and monthly flows, a Drex launch date, and unverified 2026 statements by CVM / Banxico.

Verified programme map

The table below is based on the BCB Drex page, BCB pilot page, Banxico CoDi page, and Juno operations documentation, reviewed on 2026-07-30.

Drex: what the official pilot establishes

BCB describes the Drex Platform as a DLT ecosystem where regulated intermediaries convert balances of demand deposits and electronic money so clients can access smart financial services. It is therefore inaccurate to describe every retail-facing balance as a direct BCB account or to equate Drex with a public-chain stablecoin.

The Drex pilot page states:

• end users are not pilot participants; their operations are simulated;
• Phase 1 and Phase 2 are marked concluded;
• Phase 2 involved 16 consortia / companies and 13 selected use-case themes;
• tested themes included receivables, collateralized credit, government bonds, trade finance, FX optimization, debentures, agribusiness assets, vehicles, real assets and public-network assets.

The BCB’s Phase 1 report says privacy, data protection and security still required further research. No dated nationwide launch commitment should be inferred from a pilot completion.

CoDi: payment rail, not digital peso

Banxico’s CoDi page describes CoDi as a payment / collection mechanism using QR and NFC messages over participating financial institutions and SPEI. This page does not establish that Banxico has permanently rejected a retail CBDC, nor does it support the former monthly-volume and merchant-count forecasts. CoDi should be compared with Pix or UPI as an instant-payment access layer, not labelled a Mexican CBDC.

MXNB and BRL1: named issuer and chain

Bitso’s MXNB product page identifies Juno, a Bitso company, as issuer and states 1:1 MXN backing by pesos and cash equivalents held at regulated institutions. Juno’s operations documentation lists:

• MXNB — 1:1 MXN, deployed on Arbitrum, mint / redeem via SPEI or Bitso Transfer;
• BRL1 — 1:1 BRL, deployed on Polygon, mint / redeem through Bitso Transfer.

The official sources reviewed do not name M0 or Mercado Bitcoin as co-issuers. They also do not support the former Base / Ethereum / Polygon chain list for MXNB, a $25M circulation snapshot, or a claim that Banxico “tolerates” the product as monetary policy.

Comparison boundaries

The following table shows the comparison boundaries that can be established from BCB Drex, Banxico CoDi, and the Juno operations docs. Do not add market share or an anti-dollarization effect without a dated transaction dataset.

Due-diligence implications

1. Keep pilot, production payment rail, and private token issuance as separate statuses.
2. Verify issuer identity and redemption contract; a distributor’s brand is not automatically the legal issuer.
3. Capture circulating supply and attestation with an explicit date and contract address.
4. Do not infer government approval, policy endorsement or monetary-policy intent from a token being available through a regulated company.
5. Cross-border availability does not waive FX, AML/CFT, tax or remittance rules.
