You need wallets in order to interact with decentralized apps on Ethereum, also called dApps. It holds your private key, signs your transactions, and proves your identity on-chain. Most people are familiar with browser extensions or mobile apps like MetaMask or Rabby. But there's another approach, local storage wallets, that provides more speed and better user experience.
This article explains what a local storage wallet is, how it works, and what it means for your experience on platforms like realtimeplay.xyz, a 100% on-chain casino with ultra-fast experience on MegaETH.
What Is a Local Storage Wallet?
A local storage wallet is a lightweight Ethereum wallet created and stored directly in your browser’s local storage, this is the same technology your browser uses to remember things like website settings or form data. This means the wallet is:
- Created automatically by your browser.
- Stored only on your device, never on a server.
- Ready to use immediately, without needing to install anything.
In technical terms, it's just a key pair (a public Ethereum address and a private signing key) stored securely in the browser using JavaScript APIs like window.localStorage.
Why Use a Local Storage Wallet?
Traditional wallets are great for managing multiple assets and interacting across the Ethereum ecosystem. But they're not always ideal when you're trying to:
- Create a quick wallet for fast onboarding.
- Interact with a dApp that needs sub-second feedback.
- Avoid the overhead of external wallet prompts or popups.
With a local storage wallet:
- There’s no extension to install.
- No user approval needed for every transaction.
- The experience is immediate, perfect for games that need to feel instant and fluid.
This is especially important in environments like MegaETH, where every action is an on-chain transaction and execution happens in milliseconds.
Is It Safe?
Local storage wallets give you full control and that includes responsibility.
- You own the keys. No one else, not even the dApp, can access them.
- But they’re stored in your browser, so clearing your cache or using incognito mode could mean losing access unless you back it up.
Many apps offer a “download backup” or “export wallet” option. If you plan to use your wallet regularly, make sure to back it up securely.
How Does It Work on realtimeplay.xyz?
When you visit realtimeplay.xyz, a local storage wallet is generated for you automatically (if you don’t already have one). This wallet lets you:
- Instantly start playing without installing anything.
- Sign and send transactions directly to the chain.
- Enjoy a casino experience that feels like a Web2 app but is fully on-chain.
You can also export your wallet if you ever want to import it into another Ethereum wallet app or manage it yourself.
What Happens If I Refresh or Close My Browser?
As long as you’re not in incognito mode and haven’t cleared your browser data, your wallet will persist. The next time you open the site, the same wallet is ready to use.
But again, if you clear your local storage, the wallet is gone along with access to any funds or progress. Always back it up if you care about keeping it.
