A São Paulo court has mandated that Coinbase (NASDAQ: COIN) reimburse approximately $100,000 to a customer whose cryptocurrency disappeared from his Coinbase Wallet. This ruling is grounded in Brazil's Consumer Protection Code, which holds Coinbase accountable for failing to demonstrate that the user had authorized the transaction or that adequate security measures were in place.
The case centers around an investor named Joubert, who transferred his crypto assets from various exchanges to Coinbase's platform. However, these funds later vanished without any prior consent being granted by him.
Coinbase's defense relied on the assertion that their self-custody model absolved them of any responsibility for stolen user funds. The court dismissed this argument, indicating that liability falls onto wallet developers to ensure user security. Magistrate Ju Hyeon Lee ruled that Coinbase could not provide proof that Joubert had authorized the transfer. Additionally, the company could not demonstrate that the compromised wallet employed basic security protocols, such as blocking mechanisms or two-factor authentication.
Moreover, the judge criticized Coinbase for submitting complex technical documents without adequate translations for the court's comprehension. The ruling orders Coinbase to return the full sum to Joubert along with legal fees and court costs totaling 10% of the claim.
Legal experts anticipate that this decision could set a significant precedent in Brazil, potentially shifting the legal landscape surrounding cryptocurrency wallet security. Raphael Souza, an attorney specializing in digital law, emphasized that the ruling undermines two traditional defense arguments used by crypto platforms. These include the notion that self-custody systems carry no liability for the provider and the general expectation that users alone bear responsibility for their funds.
This case highlights ongoing discussions about the responsibility of crypto platforms in protecting user assets, an issue that has been increasingly scrutinized in various jurisdictions. As one of the world's largest cryptocurrency markets, Brazil's legal interpretations could influence global standards regarding digital asset security.
