Coinbase reported that a surge in Ethereum on-chain activity over the past week has caused transaction fees to soar. From September 16 to 26, the average Gas fee was 498% higher than the previous 30-day average, and the median transaction cost of Ethereum rose from $0.09 at the beginning of the month to $1.69. In addition, Ethereum DEX transaction volume increased by 9% month-on-month, and the total transfer volume increased by 17% month-on-month, further pushing up transaction fees. Kraken pointed out that Ethereum has broken through its relative strength index (RSI) downward trend line, which can be traced back to the multi-year high of more than $4,000 in March, indicating a possible bullish shift in momentum.
