Dogechain halted transactions this weekend after developers detected a critical bug in the project\u2019s bridge contracts.<\/p>\n
Dogechain was at risk of an exploit this weekend.<\/p>\n
The project\u2019s developers found a bug on September 10 and paused block creation for several hours. On September 11<\/a>, the development team said that the network was once again live with ongoing maintenance.<\/p>\n The bug could have allowed attackers to mint wrapped DOGE (wDOGE) freely on the bridge network.<\/p>\n The project said that the fact that its network currently runs on a Proof-of-Authority (PoA) consensus mechanism allowed the team to reverse the \u201cunwarranted minting of wDOGE.\u201d It added that it would remain under PoA until the team is fully prepared to transition to Proof-of-State (PoS) consensus.<\/p>\n Dogechain noted that the issue concerned an \u201cinternal bug\u201d rather than \u201can exploit or hack.<\/span>\u201d The team assured the public that no Dogecoin (DOGE) had been lost or stolen. It added that no \u201cinternal funds\u201d had been lost either\u2014presumably referring to Dogechain (DC) and wrapped Doge (wDOGE) tokens.<\/p>\n However, some sources argue that Dogechain did indeed lose funds. Independent crypto researcher Crumbs suggested<\/a> that an attacker exploited the vulnerability to mint 9.7 million wDOGE ($600,000). The supposed attacker converted as much as $316,000 to other assets; a portion of those funds may have been deposited to Binance.<\/p>\n Dogechain contributor Roc Zacharias<\/span><\/a> responded to Crumbs and denied the theft, stating that the project \u201chad [an] internal bug [and] no hack.\u201d He continued: \u201cNo funds lost. Nothing bridged out [or] lost like you\u2019ve suggested here.\u201d<\/p>\n Despite those denials, it appears that an Ethereum address beginning with 0x78F05\u2026<\/span><\/a> has been specifically blacklisted<\/a> by Dogechain. Additionally, Dogechain\u2019s official account of events implies that funds were minted without warrant at one point, even though those mints were reversed.<\/p>\n Those facts do not confirm that an attacker successfully committed theft. However, it does seem that an individual performed transactions that could have led to a loss of funds.<\/p>\n It should be emphasized that the vulnerability affects Dogechain, not Dogecoin<\/a>. The two projects have no official relationship.\u00a0 Dogechain aims to build a Layer 2 network that allows bridged Dogecoin tokens to be used on new applications such as decentralized exchanges and NFT marketplaces.<\/p>\n Furthermore, the vulnerability described above is entirely unrelated to a data leak that recently affected Shiba Inu token<\/a>, another popular doge-themed blockchain project.<\/p>\n Disclosure: At the time of writing, the author of this piece owned BTC, ETH, and other cryptocurrencies.<\/em><\/p>\nShare this article<\/h4>\n<\/section>\n
