The U.S. Securities and Exchange Commission (SEC) has closed its investigation into Uniswap Labs, the creator of the largest decentralized trading platform on Ethereum, without pursuing any enforcement action. This decision follows similar moves by the SEC to end probes into other crypto firms such as Coinbase, OpenSea, and Robinhood. Uniswap Labs had previously received a Wells Notice from the SEC, indicating potential legal action for operating as an unregistered broker, exchange, and clearing agency. The investigation, which lasted over three years, was a significant burden on Uniswap Labs, with the company spending tens of millions of dollars in legal fees, according to COO Mary-Catherine Lader. The closure of the investigation provides relief to Uniswap Labs and its CEO, Hayden Adams, who has been vocal about the company's position. The SEC's recent actions reflect a shift in regulatory approach under new leadership, moving away from the enforcement-heavy stance of the past administration. This change has been noted by the crypto industry as a step towards a more constructive regulatory environment. Following the announcement, the UNI token experienced a surge in value.
