Since the Avalanche network implemented the Avalanche 9000 upgrade on December 16, transaction fees have dropped by an average of 75% and transaction volume has increased by more than 35%. Flipside and Bitquery data show that the current Avalanche daily transaction volume has increased to about 354,000. The upgrade includes seven improvement proposals, among which ACP-125 reduces the C-Chain smart contract base fee from 25 nAVAX to 1 nAVAX, and adjusts the validator fee from 2,000 AVAX to a monthly subscription of 1-10 AVAX, lowering the barrier to entry. Avalanche continues to optimize the DeFi ecosystem and attract more developers with the multi-chain architecture of C-Chain, P-Chain and X-Chain.
