According to Axios on August 12, multiple sources said that several venture capital funds including Andreessen Horowitz (a16z) and Union Square Ventures received letters from the SEC asking about their relationship with Uniswap Labs, the operator of a decentralized crypto exchange.

Previously, Uniswap Labs raised more than $170 million in venture capital, with its most recent round at the end of 2022 at a valuation of nearly $1.7 billion. The company received a Wells notice from the SEC earlier this year and has responded. The regulator may accuse Uniswap of being an unregistered exchange.
