Variant, a venture capital firm specializing in cryptocurrency, has successfully raised $222 million for its latest fund, Variant 4. The fund aims to invest in early-stage projects that integrate AI and crypto technologies, focusing on creating "self-sustaining economies." Partner Jesse Walden emphasized that the distinction of being a "crypto investor" will fade as crypto becomes a fundamental infrastructure akin to the internet. The fund will support projects that enhance user autonomy and security through decentralized architectures, including DeFi platforms like Uniswap and Morpho.
