Under the Trump administration, the U.S. Securities and Exchange Commission (SEC) has drastically shifted its stance on crypto enforcement, dismissing or closing investigations into over 20 major crypto companies including Ripple, Binance, Coinbase, Kraken, Uniswap Labs, OpenSea, Yuga Labs, and more. With crypto-friendly Chair Paul Atkins and the new Crypto Task Force led by Hester Peirce, the agency has abandoned the 'regulation by enforcement' approach, embracing negotiation and rulemaking instead. This article documents every major case reversal, detailing key dates, allegations, settlements, and public reactions. Topics covered include XRP's four-year lawsuit, Binance's $4.3B and $2.7B settlements, the dismissal of Coinbase's suit over SOL and MATIC tokens, the end of investigations into DeFi protocols (Uniswap, Consensys), NFT platforms (OpenSea, CyberKongz), stablecoins (PayPal's PYUSD), meme coins (HAWK), and wireless networks (Helium). The sweeping changes signal a new era of crypto regulatory clarity in the United States.
