Brazil to Report Crypto Transfers of $10,000 or More to Self-Custody Wallets

Brazil introduces $10,000 crypto reporting rules for transfers involving self-custody wallets.

Brazil will require regulated crypto firms to report transfers of $10,000 or more involving self-custody wallets to the country’s financial intelligence unit starting October 1, according to Coin Bureau.

The rule covers crypto transfers both to and from self-custody wallets, where users maintain control of the private keys rather than placing assets with a regulated custodian. Brazil’s central bank confirmed that transfers valued at or above the equivalent of $10,000 will be subject to specific reporting to the Council for Financial Activities Control, known as Coaf.

The requirement is part of Brazil’s updated framework for monitoring virtual-asset activity and preventing money laundering and terrorist financing.

$10,000 Threshold Triggers Reporting

From October 1, crypto service providers covered by the rules will have to report qualifying transactions involving self-custody wallets. The requirement applies in both directions: withdrawals from a regulated crypto platform to a self-custody wallet and deposits moving from such a wallet to a regulated provider.

The reporting obligation falls on the regulated institution handling the transaction, rather than requiring individual wallet owners to submit reports directly to Coaf.

Brazil’s central bank said the measure is intended to strengthen authorities’ ability to monitor transactions involving self-custody wallets. Because users control the private keys themselves, these wallets can provide less information for institutions conducting monitoring and risk assessments than assets held through an authorized custodian.

The $10,000 threshold is a reporting trigger rather than a restriction on the amount that can be transferred. The new rule does not ban transactions above that level or establish a maximum amount for transfers involving self-custody wallets.

24-Hour Holding Rule Begins in 2027

A separate measure will introduce an additional requirement beginning January 2027.

From January 1, crypto firms will have to apply a precautionary markets holding period of up to 24 hours to certain transfers exceeding $10,000 to self-custody wallets. The measure is designed to give providers additional time to conduct fraud-risk assessments.

The 24-hour provision differs from the October reporting requirement. The October rule concerns communication of qualifying transactions to Coaf, while the January measure establishes a temporary precautionary hold for certain outbound transfers.

Under the central bank’s framework, the 24-hour measure does not constitute a permanent freeze of assets. Providers can release or reject transactions after the applicable review process.

The two measures create separate compliance milestones for Brazil’s crypto industry: reporting of transfers involving self-custody wallets begins October 1, while the precautionary holding mechanism takes effect January 1, 2027.
