Hi Thanks for the PR in order to use activityHandler: wrapActivityHandler(EtherscanActivity), you also have to add the etherscan compatible blockexplorer info to https://github.com/enkryptcom/enKrypt/blob/main/packages/extension/src/providers/ethereum/libs/activity-handlers/providers/etherscan/configs.ts if not you have to code a custom activity handler
