No total, mais de <strong>420 milh\u00f5es de d\u00f3lares<\/strong> provenientes de <strong>hacks<\/strong> ter\u00e3o transitado livremente atrav\u00e9s da USDC sem que a empresa interviesse a tempo para congelar os fundos.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"twitter-tweet\" data-width=\"500\" data-dnt=\"true\"><p lang=\"en\" dir=\"ltr\">1\/ Welcome to the Circle <a href=\"https:\/\/twitter.com\/search?q=%24USDC&amp;src=ctag&amp;ref_src=twsrc%5Etfw\">$USDC<\/a> files.<br><br>$420M+ in alleged compliance failures since 2022, including fifteen cases of the US-regulated stablecoin issuer taking minimal action against illicit funds. <a href=\"https:\/\/t.co\/OiWZz5MrVM\">pic.twitter.com\/OiWZz5MrVM<\/a><\/p>&mdash; ZachXBT (@zachxbt) <a href=\"https:\/\/twitter.com\/zachxbt\/status\/2040055757211885953?ref_src=twsrc%5Etfw\">April 3, 2026<\/a><\/blockquote><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script>\n<\/div><\/figure>\n\n\n\n<p>O exemplo mais marcante continua a ser o recente <a href=\"https:\/\/investx.fr\/pt\/noticias-cripto\/solana-sol-crash-60-hack-drift\/\">hack do Drift Protocol na Solana.<\/a> Enquanto os atacantes desviavam cerca de 285 milh\u00f5es de d\u00f3lares, dos quais 232 milh\u00f5es em USDC, a Circle ter\u00e1 demorado mais de seis horas a reagir. Este atraso ofereceu uma janela de oportunidade perfeita para os hackers lavarem os fundos atrav\u00e9s da <strong>Bridge<\/strong> oficial da Circle (CCTP) para a Ethereum.<\/p>\n\n\n\n<p>Para os especialistas, esta lentid\u00e3o \u00e9 incompreens\u00edvel. Numa altura em que a USDC se posiciona como a stablecoin mais regulada do mercado, esta inatividade transforma-a, paradoxalmente, numa ferramenta de elei\u00e7\u00e3o para os cibercriminosos. Os <strong>market makers<\/strong> e os fornecedores de <strong>liquidez<\/strong> preocupam-se agora com as falhas gritantes na monitoriza\u00e7\u00e3o on-chain da empresa e com as consequ\u00eancias desta revela\u00e7\u00e3o.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"tether-usdt-vs-circle-usdc-um-contraste-gritante-perante-os-hackers\">Tether (USDT) vs Circle (USDC): Um contraste gritante perante os hackers<\/h2>\n\n\n\n<p>A investiga\u00e7\u00e3o de ZachXBT tamb\u00e9m destaca uma diferen\u00e7a de tratamento flagrante entre a Circle e a sua principal concorrente, a Tether. Durante o ataque massivo \u00e0 Bybit em fevereiro de 2025 pelo grupo norte-coreano Lazarus, a Tether congelou os endere\u00e7os associados em poucas horas. Por seu lado, a Circle ter\u00e1 aguardado mais 24 horas, dando tempo aos criminosos para organizarem o levantamento do seu saque:<\/p>\n\n\n<blockquote class=\"wp-block-quote\">\n\n\n<p>\u00abA 28 de fevereiro, 106 000 USDT e 338 000 USDC foram transferidos para o endere\u00e7o fraudulento 0xDa2. As autoridades policiais, a Bybit e especialistas do setor privado enviaram pedidos de congelamento \u00e0 Tether e \u00e0 Circle. A Tether congelou o endere\u00e7o em poucas horas. A Circle demorou mais 24 horas a reagir\u00bb, declara.<\/p>\n\n\n<\/blockquote>\n\n\n<p>Esta pol\u00edtica de in\u00e9rcia verifica-se noutros casos pol\u00e9micos, como o hack da <strong>Cetus <a href=\"https:\/\/investx.fr\/pt\/investir-criptomoedas\/exchange\/melhores-exchanges-dex\/\">DEX<\/a> (200 milh\u00f5es de d\u00f3lares)<\/strong> ou o da <strong>GMX<\/strong>. A Circle justifica frequentemente a sua ina\u00e7\u00e3o com a necessidade de aguardar por ordens judiciais formais. No entanto, num ecossistema onde as transa\u00e7\u00f5es s\u00e3o executadas em poucos segundos, esta burocracia alimenta um sentimento de <strong>preocupa\u00e7\u00e3o<\/strong> entre os investidores institucionais.<\/p>\n\n\n\n<p>Perante estas revela\u00e7\u00f5es, o mercado teme uma quebra na confian\u00e7a depositada nas stablecoins centralizadas. Se a Circle n\u00e3o conseguir provar a efic\u00e1cia do seu motor de conformidade, supostamente operacional desde 2024, os utilizadores poder\u00e3o virar-se para alternativas mais reativas ou totalmente descentralizadas para protegerem as suas carteiras.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"podera-a-usdc-sobreviver-a-esta-crise-de-confianca-e-manter-a-sua-paridade\">Poder\u00e1 a USDC sobreviver a esta crise de confian\u00e7a e manter a sua paridade?<\/h2>\n\n\n\n<p>Estas alega\u00e7\u00f5es surgem na pior altura para a Circle, que procura consolidar a sua posi\u00e7\u00e3o de l\u00edder institucional antes do pr\u00f3ximo bull run. A revela\u00e7\u00e3o destas falhas poder\u00e1 desencadear uma queda severa da sua quota de mercado face \u00e0 USDT. Os protocolos descentralizados, que dependem massivamente da USDC para as suas pools de liquidez, poder\u00e3o rever a sua gest\u00e3o de riscos associados a contrapartes.<\/p>\n\n\n\n<p>A quest\u00e3o da centraliza\u00e7\u00e3o volta assim ao centro dos debates. Por um lado, os reguladores exigem congelamentos imediatos para combater o branqueamento de capitais. Por outro, a lentid\u00e3o de execu\u00e7\u00e3o da Circle prova que o modelo atual \u00e9 inadaptado \u00e0s urg\u00eancias da blockchain. Se nenhuma reforma interna for anunciada rapidamente, este caso poder\u00e1 marcar um ponto de viragem decisivo na guerra das stablecoins.<\/p>\n\n\n\n<p>Enquanto o mercado cripto digere esta not\u00edcia, uma quest\u00e3o paira na mente de todos os traders: ir\u00e3o as institui\u00e7\u00f5es continuar a acumular USDC ou assistiremos a uma migra\u00e7\u00e3o massiva para outros ativos de ref\u00fagio?<\/p>\n\n\n\n<p>Para j\u00e1, o mercado bolsista est\u00e1 fechado e as a\u00e7\u00f5es da <strong>Circle (CRCL)<\/strong> ainda n\u00e3o sofreram a rea\u00e7\u00e3o do mercado.
