De facto, uma falha cr\u00edtica permitiu que um atacante desviasse <strong>cerca de 101 400 $ em USDC<\/strong> e <strong>USDC.e<\/strong> das pools de liquidez da <strong>Huma Finance na rede <a href=\"https:\/\/investx.fr\/pt\/investir-criptomoedas\/comprar\/polygon\/\">Polygon<\/a><\/strong>. Segundo os dados on-chain, o ataque foi executado numa \u00fanica transa\u00e7\u00e3o, explorando uma vulnerabilidade l\u00f3gica em vez de uma falha criptogr\u00e1fica.<\/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\">Earlier today a vulnerability in Huma\u2019s legacy v1 contracts on Polygon was exploited for 101,400 USDC.<br><br>No user funds at risk and PST is not impacted.

Este bug permitia alterar o estado de uma conta n\u00e3o autorizada para &#8220;GoodStanding&#8221;, contornando assim todas as etapas de aprova\u00e7\u00e3o. O atacante conseguiu esvaziar as reservas sem acionar qualquer alerta, provocando um sentimento <strong>bearish<\/strong> tempor\u00e1rio em torno da infraestrutura envelhecida do protocolo.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"v1-vs-v2-porque-e-que-este-problema-na-defi-e-tao-massivo\">V1 vs V2: Porque \u00e9 que este problema na DeFi \u00e9 t\u00e3o massivo?<\/h2>\n\n\n\n<p>Este <strong>exploit<\/strong> evidencia um problema persistente na DeFi: a gest\u00e3o dos antigos smart contracts. O ataque visou os <strong>contratos V1 BaseCreditPool<\/strong>, uma arquitetura obsoleta que os programadores j\u00e1 estavam a desativar. Na blockchain, um contrato implementado permanece ativo indefinidamente, criando <strong>&#8220;contratos zombie&#8221;<\/strong> que se tornam alvos preferenciais para os hackers.<\/p>\n\n\n\n<p>Felizmente, a equipa da Huma Finance reagiu rapidamente, colocando em pausa todos os contratos V1 restantes. Confirmaram tamb\u00e9m que o seu sistema V2, totalmente reconstru\u00eddo na blockchain <strong><a href=\"https:\/\/investx.fr\/pt\/aprender-criptomoedas\/cripto\/solana\/\">Solana<\/a><\/strong>, n\u00e3o foi minimamente afetado. Os fundos dos utilizadores nesta nova vers\u00e3o, bem como o token PST, est\u00e3o seguros. Esta transi\u00e7\u00e3o tecnol\u00f3gica para a Solana comprova a import\u00e2ncia de uma arquitetura moderna para evitar este tipo de cat\u00e1strofes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"huma-bate-todos-os-recordes\">Huma bate todos os recordes&nbsp;<\/h2>\n\n\n\n<p>Al\u00e9m disso, o token PST e a V2 completa na Solana j\u00e1 gerem cerca de ~179 M$ de liquidez e 13 mil milh\u00f5es de volume. De facto, isto acontece numa altura em que a Huma Finance se encontra em plena expans\u00e3o.<\/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\">It feels good seeing how much <a href=\"https:\/\/twitter.com\/humafinance?ref_src=twsrc%5Etfw\">@humafinance<\/a> has grown in just 5 months.<br><br>Some recent Huma Finance stats:<br><br>\ud83d\udfeb Total Transaction Volume: $12,985,476,054<br>\ud83d\udfeb Origination Volume: $6,552,955,265<br>\ud83d\udfeb Payback Volume: $6,432,520,789<br>\ud83d\udfeb Total Active Liquidity: $178,865,230<br>\ud83d\udfeb PayFi Assets:\u2026 <a href=\"https:\/\/t.co\/3exe1cp0fp\">https:\/\/t.co\/3exe1cp0fp<\/a> <a href=\"https:\/\/t.co\/ykosLyAq43\">pic.twitter.com\/ykosLyAq43<\/a><\/p>&mdash; Timi (@timiondegen) <a href=\"https:\/\/twitter.com\/timiondegen\/status\/2053761449126666457?ref_src=twsrc%5Etfw\">May 11, 2026<\/a><\/blockquote><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script>\n<\/div><\/figure>\n\n\n\n<p>Recorde-se que a Huma Finance \u00e9 a <strong>primeira rede PayFi<\/strong> (Payment Finance), uma infraestrutura DeFi que permite a empresas e institui\u00e7\u00f5es acederem instantaneamente a liquidez para financiar os seus pagamentos globais (faturas, pagamentos transfronteiri\u00e7os, liquida\u00e7\u00f5es de cart\u00f5es banc\u00e1rios, etc.).<\/p>\n\n\n\n<p>Em suma, a blockchain tokeniza os fluxos de pagamentos futuros para oferecer cr\u00e9dito em tempo real, gerando simultaneamente rendimento para os fornecedores de liquidez. Em apenas 5 meses, o protocolo explodiu com quase <strong>13 mil milh\u00f5es $ de volume total<\/strong> de transa\u00e7\u00f5es (dos quais 6,55 mil milh\u00f5es $ de origina\u00e7\u00e3o e 6,43 mil milh\u00f5es $ de reembolsos), 178,87 milh\u00f5es $ de liquidez ativa, <strong>130,17 milh\u00f5es $ de ativos PayFi<\/strong> e mais de <strong>119 800 depositantes<\/strong>. Estes n\u00fameros impressionantes demonstram a forte ado\u00e7\u00e3o desta nova categoria que aproxima a DeFi da finan\u00e7a tradicional.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"os-protocolos-defi-estao-realmente-prontos-para-o-proximo-bull-run\">Os protocolos DeFi est\u00e3o realmente prontos para o pr\u00f3ximo Bull Run?<\/h2>\n\n\n\n<p>Este incidente na <strong>Polygon<\/strong>, que ocorre pouco depois de outros ataques semelhantes, levanta quest\u00f5es cruciais sobre a seguran\u00e7a global da DeFi. Numa altura em que o mercado anseia por um novo rali e muitos tokens apontam para um novo ATH, a persist\u00eancia destas <strong>vulnerabilidades<\/strong> nas vers\u00f5es antigas poder\u00e1 travar a ado\u00e7\u00e3o institucional.<\/p>\n\n\n\n<p>Al\u00e9m disso, a Huma Finance encontrava-se em pleno boom de ado\u00e7\u00e3o. Resta esperar que este incidente n\u00e3o tenha um impacto demasiado negativo no futuro. A rea\u00e7\u00e3o r\u00e1pida e eficaz da Huma j\u00e1 \u00e9 um aspeto positivo. Contudo, o aumento dos <strong>hacks na DeFi<\/strong> e nos smart contracts continua a ser uma grande inc\u00f3gnita a longo prazo.<\/p>\n\n\n\n<p>Em conclus\u00e3o, os programadores devem imperativamente proteger ou destruir os seus contratos antigos antes de lan\u00e7arem novas itera\u00e7\u00f5es. Sem uma limpeza massiva destas falhas hist\u00f3ricas, outros protocolos poder\u00e3o ver a sua liquidez desaparecer de um dia para o outro.
