New safeguards will give Brazilian crypto platforms more time to identify potentially fraudulent transfers before funds leave the ecosystem.
Brazil’s central bank is introducing precautionary checks of up to 24 hours for certain crypto transfers sent to foreign platforms and self-custody wallets.
Under Resolution BCB No. 584, virtual asset service providers will have to hold outbound transfers of at least US$10,000. The threshold can be reached through a single transaction or through a customer’s cumulative transfers on the same day.
Providers will also have to apply precautionary holds to other transfers identified for further scrutiny through their internal risk-management procedures.
The measure does not impose a permanent block or require every affected transaction to remain suspended for a full day. Providers may release assets earlier when their assessment has been completed in accordance with the central bank’s requirements.
Customers must be informed when a transaction is placed under review. Providers will also have to keep records covering confirmed and attempted fraud, suspicious activity and the measures taken in response.
