Ethereum Event Listener (Proof-of-Concept)

Description

This project is an Ethereum Event Listener written in Go and serves as a proof of concept. It connects to an Ethereum client using RPC, subscribes to specific contract event logs, and processes these events as they occur. As a proof of concept, it will not cover all edge cases or be suited for production use without further development and testing.
