When developers are creating smart contracts, they sometimes need to use specific wallets on their browsers. Exporting private keys carries certain risks. Also, when developers need to switch between different blockchains or wallets for testing purposes, vue-dapp-starter and nuxt-dapp conveniently provide a simple interface for connecting browser wallets. 

You can write a simple script to interact with the contract or execute functions with the browser/mobile crypto wallets by refreshing the browser, and directly output the results on the browser console.
