Uniswap Labs has once again urged the US Securities and Exchange Commission (SEC) to abandon its proposal to regulate decentralized finance (DeFi). The SEC has been considering an expansion of the definition of an exchange since April 2023, to include DeFi participants. Uniswap argues that the recent Supreme Court decision in the Loper Bright Enterprises v. Raimondo case, known as the Chevron decision, means the SEC's efforts to amend the definition of "exchange" would be a waste of resources. Uniswap also suggests that the proposed amendment is too broad and would lead to inconsistencies and unclear guidance.
