Hey guys, does someone know if there is a good way to monitor when an address receives eth ?

You can either create it yourself or use existing services. Google gave for example this: https://aleth.io/products/monitoring

Better to code own solution i think

I was thinking if there was some kind of realtime way of doing it, similar to how its possible to subscribe to events emitted from contracts

But i guess polling through etherscan api is the way
