Uniswap, along with other major crypto projects such as Morpho, MetaMask, Sui, and Aave, have confirmed they were not affected by the recent NPM supply chain attack. The incident involved the compromise of a developer's NPM account, resulting in malicious code being injected into widely-used third-party packages. The attack targeted cryptocurrency theft and affected packages that have been downloaded over a billion times, posing a significant risk to the JavaScript ecosystem. Despite the potential threat, these prominent projects have assured their users of their security and integrity.
