Crypto regulation in Brazil: what Central Bank rules change for users

What was regulated

Brazil's Central Bank published Resolutions 519, 520 and 521 to govern authorization, operation and certain virtual-asset services. The rules help define who can provide services, what obligations apply and how some operations connect to foreign-exchange and international-capital rules.

For someone using an exchange or custody service, this provides more reference points for evaluating a company. It is important not to confuse regulation of a provider with a guarantee about the price of a cryptoasset or about any individual transaction.

What changes in practice

The framework includes governance, security, internal controls, transparency and anti-money-laundering requirements for covered services. It also classifies providers as intermediaries, custodians and cryptoasset brokers. The rules came into force in February 2026, with specific obligations and timelines.

In certain transfers to or from self-custody wallets, providers must identify the wallet owner and maintain processes to verify the origin and destination of assets in the situations covered by the rules. This can mean more information or verification steps in some flows.

What remains the user's responsibility

Even in a more regulated environment, you should still verify the official website, protect email and accounts with MFA, understand costs and make small test transfers. No rule stops a person from sending assets to the wrong address, falling for phishing or buying something without understanding volatility.

How to evaluate a platform

Look for legal name, support channels, terms of use, custody policy, fees, supported networks and how risks are disclosed. A promise of returns is never proof of compliance.
