Getting Started To Web3 With Atomic Wallet Extension

This presentation-style guide walks you through installing the Atomic Wallet browser extension, securing it correctly, and connecting to Web3 apps (dApps). You’ll learn best practices, common pitfalls, and where to find trusted, official resources.

Why a Browser Extension for Web3?

Web3 apps live right in your browser. A wallet extension acts as your Web3 passport—managing keys, approving transactions, and helping you interact with blockchains safely. Atomic Wallet’s extension is non-custodial, meaning you hold the keys. That responsibility gives you freedom and requires good security habits. This guide strikes that balance: fast setup, strong protection, and practical steps to start exploring DeFi, NFTs, and more.

Prerequisites

A Chromium-based browser (Chrome, Brave, Edge) or another supported browser.
Some basic familiarity with sending/receiving crypto, gas fees, and networks.
A private environment to write down your 12-word backup phrase.

Tip

Use a fresh browser profile for Web3 to reduce extension conflicts and improve privacy.

Security Mindset

With non-custodial wallets, you are the safeguard. Never paste your seed phrase online, never share screenshots of it, and beware look-alike websites. Bookmark official links and verify URLs before installing anything.

Note

If something feels off—pop-ups, urgent messages, “support agents” asking for keys—stop and verify via official channels.

Install & Set Up

Step 1 — Get the Official Extension

Open the Atomic Web3 Wallet page or the Chrome Web Store listing.
Confirm the publisher name and reviews, then click Add to browser.

Step 2 — Create or Import a Wallet

Choose Create for a new wallet or Import to restore with your 12-word phrase.
Write your backup phrase on paper (twice). Store in two separate, offline locations.
Set a strong password (use a password manager; avoid reusing passwords).

Step 3 — Enable Networks & Add Assets

In Settings, enable the chains you plan to use (e.g., Ethereum, Polygon, BSC).
Add any custom tokens by verified contract address before receiving funds.

Pro Setup Tips

Turn on auto-lock after a short idle period (e.g., 1–5 minutes).
Use a hardware wallet for larger, long-term holdings and keep only pocket money in the browser.
Keep your OS and browser up to date to patch security flaws.

Connect to a dApp

Most dApps have a Connect Wallet button. Choose Atomic Wallet (or WalletConnect where supported), approve the connection, then confirm transactions in the extension.

Safe Interaction Checklist

Double-check the site URL each visit; bookmark trusted dApps.
Read on-screen prompts—network, amount, and contract interactions—before approving.
Start with small test transactions on a new dApp.

Common Troubleshooting

Transactions stuck: Check network congestion; try speeding up or canceling if supported.
Wrong network: Match your wallet network to the dApp’s network.
Token not visible: Add the token by its verified contract address.

Best Practices for Ongoing Security

Keep your seed phrase offline. Never type it on websites or share it with anyone.
Lock the wallet when not in use and avoid installing random extensions.
Use separate wallets for experimenting vs. serious funds.
Regularly review connected dApps and revoke unused approvals on supported networks.

Reminder

Non-custodial means you control your assets—and you’re responsible for keeping them safe. Treat approvals and signatures like you would a bank transfer.
