# Introduction

BlockHopper is the first ERC 404 multichain game running on a zero-fee [Pion portal](https://pion.muon.net/) (bridge). 

In the HopperVerse, players are thrust into the degenerate world of a genius, unwashed and excessively caffeinated inventor, Dr Blocktor, where, in his quest to harness the power of ERC404, creates a portal gun to bridge from chain-to-chain, to allow him to collect $GUN tokens from every supported chain. 

His ultimate goal? To amass all six variations of the $GUN tokens, thereby unlocking the grand prize: the Crystal Fund. With the Crystal fund he then has the potential to open more zero-fee portals to other EVM chains, Solana and even Cosmos.
