import { TatumSDK, Ethereum, Network } from '@tatumio/tatum'

(async () => {
    const tatum = await TatumSDK.init<Ethereum>({network: Network.ETHEREUM})
    
    const monitoredAddress = '0xF64E82131BE01618487Da5142fc9d289cbb60E9d'
    
    const subscription = await tatum.notification.subscribe.outgoingNativeTx({
        address: monitoredAddress,
