According to CoinMeta, today's top gainers in the crypto market were decentralized exchanges and layer-2 network tokens, namely Arbitrum ( ARB ), Uniswap ( UNI ), and Raydium ( RAY ). Among them, ARB rose by 30.26% in the past 24 hours, currently trading at $0.2145 with a gain of 27.98%, and is now valued at $8.73. The U.S. Securities and Exchange Commission ( SEC ) approved a temporary exemption on September 17th, allowing tokenized U.S. stocks to be traded through licensed automated market makers, a decision that is seen as a direct catalyst for the increase in prices of these related tokens.
