According to Wu, according to DeFiLlama data, from March 3 to March 6, the trading volume of Solana's on-chain DEX has exceeded US$2 billion for four consecutive days, of which the trading volume on March 5 reached US$2.85 billion, setting a new single-day high. The active on-chain transactions may be one of the reasons for the current congestion of the Solana network. It is worth noting that on March 5, the multi-chain DEX trading volume was about US$14 billion, the highest since March 12, 2023, among which the on-chain DEX trading volumes of Solana, Arbitrum and Base all set a new single-day high.
