Simple script for retrieving, modifying, and updating zapper.fi wallets. Meant to be run in the console.

zapperfiWallets.js

////////////////////////////////////////////////////
// zapper.fi
//////////////////////////////////////////////////////


// grab persist:account from localStorage and parse it
let persistAccount = JSON.parse(localStorage.getItem("persist:account"))
Object.keys(persistAccount).forEach(key => {
    let value = JSON.parse(persistAccount[key]);
    persistAccount[key] = value;
});

//add a test item to the wallet
persistAccount.wallets.push(persistAccount.wallets[0]);

//Stringify the values of the object
Object.keys(persistAccount).forEach(key => {
    let stringValue = JSON.stringify(persistAccount[key]);
    persistAccount[key] = stringValue;
});

// Stringify the whole thing
persistAccount = JSON.stringify(persistAccount);
// add it back to local storage
localStorage.setItem("persist:account", persistAccount);

similar script but for Frame wallets - https://gist.github.com/Beasta/3eaec00449086128eef36339bff47f68
