Zipcoin Shut Down After Codebase Breach
Zipcoin, an Ethereum-based project, announced an immediate shutdown on October 22, 2026, following a second security breach in less than a week. The team discovered a full compromise of its codebase on October 21, which was the deciding factor. The project's token, ZC, reportedly fell 84% within a day of the news. Zipcoin's team still controls wallets holding about 22 million tokens, which it plans to sell after a short exit window for existing holders. The shutdown was announced through an X post from the project’s account, zipcoincash.
