All PIX participants (industry-wide)

The Central Bank of Brazil issued Resolution 589 mandating that all financial institutions and fintechs participating in the PIX instant payments system implement self-service MED (Mecanismo Especial de Devolução) fraud recovery functionality within their apps by October 2025. The MED 2.0 upgrade, planned for February 2026, will significantly enhance fraud tracing capabilities by enabling blocking across five account layers. This builds on earlier regulatory measures including Resolution No. 6 (2023), which mandates fraud information sharing among institutions, and BCB Resolution 343, which requires biannual customer checks for fraud risks. These measures are part of Brazil's broader effort to combat financial crime in its rapidly growing instant payments ecosystem, which has direct implications for BaaS providers and fintechs operating in the Brazilian market.
