Ao explorar uma falha na <strong>bridge cross-chain<\/strong> da KelpDAO, o hacker conseguiu gerar artificialmente mais de 116 500 tokens rsETH.

O pirata inform\u00e1tico conseguiu assim pedir emprestados mais de 280 milh\u00f5es de d\u00f3lares em verdadeiros WETH e ETH antes que os liquidadores pudessem reagir. Esta manobra deixou o protocolo com uma d\u00edvida incobr\u00e1vel colossal.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"764\" src=\"https:\/\/media.investx.fr\/wp-content\/uploads\/sites\/2\/2026\/04\/19122537\/ZROUSDT_2026-04-19_09-20-31-1024x764-1.jpg\" alt=\"Pre\u00e7o do ZRO em 16 horas com RSI\" class=\"wp-image-119453\" srcset=\"https:\/\/media.investx.fr\/wp-content\/uploads\/sites\/2\/2026\/04\/19122537\/ZROUSDT_2026-04-19_09-20-31-1024x764-1.jpg 1024w, https:\/\/media.investx.fr\/wp-content\/uploads\/sites\/2\/2026\/04\/19122537\/ZROUSDT_2026-04-19_09-20-31-1024x764-1-300x224.jpg 300w, https:\/\/media.investx.fr\/wp-content\/uploads\/sites\/2\/2026\/04\/19122537\/ZROUSDT_2026-04-19_09-20-31-1024x764-1-768x573.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Perante esta hemorragia, o mercado reagiu rapidamente.
