ChainCatcher news, according to The Block data, the crypto developer activity on Ethereum and non-EVM compatible chains significantly declined in 2022. Among them, the weekly active developers on non-EVM chains saw the largest drop. The activity on Ethereum and EVM-compatible chains also decreased, but Ethereum itself still maintains a significant share.It is reported that developer activity is an important metric for measuring the health of the blockchain ecosystem; it often reflects the overall on-chain activity and price situation. When funds are withdrawn from the ecosystem, the funding available for new projects and developers decreases.According to Gokustats data, despite the significant decline in activity on EVM and non-EVM chains, the number of contracts deployed on the L2 platform Arbitrum saw a significant increase in the fourth quarter. This may be due to speculation and enthusiasm regarding the Arbitrum token airdrop, which caused on-chain transaction costs to surge at the end of June, with daily trading volume hitting an all-time high.
