DoinGud was a Polygon-based NFT marketplace founded in 2021 that raised $5 million to connect creators with charitable causes via blockchain. The platform is reported to have ceased active operations and was reportedly acquired in early 2024; however, its smart contracts remained deployed and holding funds. On September 21, 2026, an attacker exploited a bid-record-clearing flaw in DoinGud's Diamond bidding contract on Polygon, draining approximately $35,486 USDC.e via a flash loan. The incident illustrates the ongoing risk posed by dormant DeFi and NFT contracts that retain live balances after a platform winds down.
