Memecoin trading on Solana's decentralized exchanges (DEX) has sharply declined, now representing just 10.17% of total DEX volume, a significant drop from 67.54% a year ago, according to Solanafloor. Despite this downturn, Solana's overall DEX activity remains robust, with $SOL-stablecoin pairs dominating 73.16% of trading volume. Prop AMMs, especially HumidFi, are major contributors to this activity, handling billions in daily trades and securing 34% of the DEX market share. Additionally, Uniswap's integration of Solana support through the Jupiter API marks a notable development in the DeFi sector, potentially influencing future trading dynamics.
