The financial damage in this instance remained contained at approximately $140,000, but the technical pattern remains relevant for other treasury based systems.\n\nOur Assessment\n\nINK Finance lost around $140,000 after attackers bypassed whitelist verification in its treasury authorization system using a spoofed claimer contract. A Balancer V2 flash loan routed from Railgun into Polygon increased execution efficiency but was not the primary vulnerability. The incident adds to a series of access control related breaches in 2026 that focus on treasury authorization layers rather than liquidity pools or pricing mechanisms, highlighting operational permission design as a recurring point of failure in DeFi infrastructure.\n\n"},{"@type":"WebPage","@id":"https:\/\/www.kryptocasinos.com\/en\/news\/ink-finance-140k-treasury-whitelist-exploit-polygon\/","url":"https:\/\/www.kryptocasinos.com\/en\/news\/ink-finance-140k-treasury-whitelist-exploit-polygon\/","name":"INK Finance $140K Treasury Exploit on Polygon","isPartOf":{"@id":"https:\/\/www.kryptocasinos.com\/en\/#website"},"primaryImageOfPage":{"@id":"https:\/\/www.kryptocasinos.com\/en\/news\/ink-finance-140k-treasury-whitelist-exploit-polygon\/#primaryimage"},"image":{"@id":"https:\/\/www.kryptocasinos.com\/en\/news\/ink-finance-140k-treasury-whitelist-exploit-polygon\/#primaryimage"},"thumbnailUrl":"https:\/\/www.kryptocasinos.com\/wp-content\/uploads\/2026\/05\/ink-finance-140k-treasury-whitelist-exploit-polygon.jpg","datePublished":"2026-05-12T09:04:46+02:00","description":"INK Finance lost about $140,000 after attackers bypassed treasury whitelist checks using a spoofed contract and a Balancer V2 flash loan on Polygon.","inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/www.kryptocasinos.com\/en\/news\/ink-finance-140k-treasury-whitelist-exploit-polygon\/"]}]},{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/www.kryptocasinos.com\/en\/news\/ink-finance-140k-treasury-whitelist-exploit-polygon\/#primaryimage","url":"https:\/\/www.kryptocasinos.com\/wp-content\/uploads\/2026\/05\/ink-finance-140k-treasury-whitelist-exploit-polygon.jpg","contentUrl":"https:\/\/www.kryptocasinos.com\/wp-content\/uploads\/2026\/05\/ink-finance-140k-treasury-whitelist-exploit-polygon.jpg","width":1408,"height":736,"caption":"Server nodes connected by glowing lines, open vault spilling coins, cracked shield with a green checkmark overlay."},{"@type":"BreadcrumbList","@id":"https:\/\/www.kryptocasinos.com\/en\/news\/ink-finance-140k-treasury-whitelist-exploit-polygon\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https:\/\/www.kryptocasinos.com\/en\/"},{"@type":"ListItem","position":2,"name":"INK Finance Loses $140K in Treasury Whitelist Exploit"}]},{"@type":"WebSite","@id":"https:\/\/www.kryptocasinos.com\/en\/#website","url":"https:\/\/www.kryptocasinos.com\/en\/","name":"Kryptocasinos.com","description":"","inLanguage":"en-US"},{"@type":"Organization","@id":"https:\/\/www.kryptocasinos.com\/en\/#organization","name":"Kryptocasinos.com","url":"https:\/\/www.kryptocasinos.com\/en\/","logo":{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/www.kryptocasinos.com\/en\/#\/schema\/logo\/image\/","url":"https:\/\/www.kryptocasinos.com\/wp-content\/uploads\/2025\/06\/kryptocasinos-com-logo.svg","contentUrl":"https:\/\/www.kryptocasinos.com\/wp-content\/uploads\/2025\/06\/kryptocasinos-com-logo.svg","width":109,"height":34,"caption":"Kryptocasinos.com"},"image":{"@id":"https:\/\/www.kryptocasinos.com\/en\/#\/schema\/logo\/image\/"},"sameAs":["https:\/\/www.facebook.com\/kryptocasinoscomm\/"],"description":"Discover top-rated crypto casinos for %%currentyear%% with fast Bitcoin payouts, trustworthy security, and fair bonuses.
