Most browsers automatically disable unsigned components; you must manually enable the utility by toggling the switch next to its name. For Chromium-based browsers, navigate to chrome://extensions/. In Firefox, access the menu and select "Add-ons and Themes." Connection errors often stem from mismatched networks. Verify that the active network within the interface matches the one your decentralized application is using. A common symptom is a transaction that remains pending indefinitely; this typically indicates a network ID conflict. Cross-reference the chain ID, such as 56 for BNB Smart Chain or 1 for Ethereum Mainnet, on both platforms. Persistent problems may require clearing the local state. Use the built-in reset function found in the settings menu, often labeled "Reset Wallet" or "Clear Data." This action clears transaction caches and resets permissions without affecting your recovery phrase. Before proceeding, ensure your 12 or 24-word mnemonic phrase is physically written down and fully secure; this sequence is the only way to restore access to your addresses and assets on any device. For transaction failures, prioritize adjusting the gas settings. Manually set the gas limit 20% higher than the estimated amount for complex smart contract interactions, like token swaps or NFT minting. A "transaction underpriced" error directly signals a gas price too low for current network congestion; increase the Gwei value using a blockchain explorer to gauge live market rates. Coin98 Wallet Extension Setup Troubleshooting Guide Confirm the add-on is installed from the official Chrome Web Store or Firefox Add-ons site; counterfeit versions are a primary source of failure. If the icon disappears from your browser's toolbar, navigate to your browser's extensions management page (chrome://extensions or about:addons) and ensure it's both enabled and pinned for quick access. A persistent "Connecting..." state often resolves by simply restarting the browser completely, which clears cached connection errors. For transaction errors, manually switch the network node within the app's settings; the default RPC endpoint might be temporarily congested. Clear the application's cached data through its settings menu, then re-import your recovery phrase–this fixes most display and sync glitches without affecting your on-chain assets. Browser conflicts are common. Disable other crypto management tools one by one to identify interference, especially those that also inject Web3 providers. Always record your secret recovery phrase on paper during initial configuration; without it, regaining access to your funds is impossible if local data corrupts. Update your browser. An outdated version can cause compatibility failures with the latest security protocols the software requires to operate. Browser Compatibility and Extension Installation Errors Confirm your browser version matches the add-on's minimum requirements; for example, Chromium-based applications like Chrome and Brave need version 88 or later, while Firefox requires at least version 89. Blocked installations often stem from browser security settings. Access chrome://extensions/ or about:addons, enable "Developer mode," and attempt to load the unpacked component directly if the official store fails. Specific conflicts arise from: Outdated browser cores in some forks or mobile applications. Overly restrictive security or anti-virus software intercepting the file. Remnants of a prior, incomplete installation causing signature errors. A "Manifest version is invalid" or "Package is corrupted" notification typically indicates a failed download. Clear your browser's cache, disable any download managers, and fetch the installation file again from the primary source. For Firefox users, "This add-on could not be installed because it has not been verified" is common. Temporarily, you can adjust about:config settings (xpinstall.signatures.required to false), but revert this after installation for security. Operating system architecture can be a factor; a 64-bit browser will not install a 32-bit module. Verify your software's bit version in the system settings. If the add-on icon disappears after installation or fails to activate, check for conflicting privacy extensions (like script blockers) that may be preventing the injection of necessary scripts into web pages. Whitelist the add-on in their settings. Persistent failures necessitate a clean reinstall: remove the component entirely, restart the application, and install afresh. This resolves most permission and file-lock issues. Solving "Invalid Mnemonic Phrase" or Secret Recovery Issues Immediately verify that you are entering the exact sequence of 12 or 24 words provided during your vault's creation, with each word separated by a single space and no trailing spaces at the start or end of the phrase. Manually typing the phrase is more reliable than pasting; check for common errors like confusing 'b' and 'd' in similar words (e.g., "brain" vs. "drain") or misreading handwriting. Ensure your keyboard language is set to English and that autocorrect is disabled, as it can silently substitute terms. If a phrase consistently fails, methodically write each word on paper and cross-reference it with an official BIP39 word list to confirm spelling and validity. Some interfaces require the phrase in a specific order, so confirm you are not mixing phrases from different assets. If you used a passphrase (a 13th or 25th word), it must be appended exactly as originally created, considering it is case-sensitive. Recovery tools that operate offline can help validate the checksum of your mnemonic without exposing it to network risks. Persistent failure often indicates an incorrect or incomplete seed phrase; recovery from a backup record is the only path forward. Fixing Connection Problems with dApps and Networks Force a network refresh directly in your browser. Clear the site's cached data by opening Developer Tools (F12), navigating to the 'Application' tab, selecting 'Storage', and clicking 'Clear site data'. This resolves most interface freezing issues by removing corrupted local data that conflicts with the blockchain's current state. Manually add the correct RPC endpoints if automatic detection fails. Public RPCs are often overloaded. Use a dedicated service to find alternative endpoints with lower latency. Incorrect Chain ID settings are a primary cause of failed transactions; always verify this parameter matches the network's official specification. For example, Polygon Mainnet requires Chain ID 137, not 89.

Navigate to chrome://extensions/, find the crypto tool, click "Details", and ensure "Allow this extension to read and change site data" is set to "On all sites" or "On specific sites" if you prefer granular control. A mismatch here silently blocks the script injection needed for dApp interaction. Simultaneously, disable competing financial plugins to prevent signature request conflicts, as multiple injectors can cause the webpage to fail to detect any active provider. Q&A: I installed the Coin98 extension but the icon isn't showing in my browser toolbar. How do I fix this? This is a common issue. First, click the puzzle piece or extensions icon in your browser (usually top-right). Find Coin98 in the list and ensure it's pinned or set to "show in toolbar." If it's not in the list, the installation may have failed. Go to your browser's extension management page (like chrome://extensions), remove the Coin98 extension, and reinstall it from the official Chrome Web Store or Firefox Add-ons site. Restart your browser after the new installation. After setting up, my wallet shows zero balance, but I know my address has funds. What's wrong? Your balance is likely correct. The extension needs to be connected to the correct network to display specific assets. Check the network selector at the top of the extension. If you're looking for Ethereum assets, ensure you're on the Ethereum Mainnet. For Solana, select Solana Mainnet. Each network operates independently. Also, verify that you are viewing the correct wallet address within your wallet—you might have generated multiple accounts. If the issue persists, try adding the token contract address manually using the "Add Token" feature. I cannot connect the Coin98 extension to a dApp website. The "Connect Wallet" button does nothing. Several factors can cause this. First, confirm the dApp supports the Coin98 wallet. Then, check for these points: 1) Ensure the Coin98 extension is unlocked. 2) Your browser may have blocked pop-ups from the dApp site; look for a pop-up blocker icon in the address bar and allow permissions. 3) Clear your browser cache for that site and reload the page. 4) Try a different browser. A conflict with other wallet extensions (like MetaMask) is possible; try disabling others temporarily. Also, ensure your browser and the Coin98 extension are updated to their latest versions. I lost my recovery phrase. Can I recover my wallet using the extension's password or browser data? No. Your password only secures access to the extension on that specific device and browser. It does not generate your recovery phrase. The phrase is the absolute master key to your wallet and funds. Without the 12 or 24-word recovery phrase, you cannot regain access to your wallet if you uninstall the extension, clear browser data, or use a new device. If you have lost your phrase, your only option is to use it to recover the wallet on a new extension immediately, before your current browser session is lost. Write it down and store it securely offline. Every time I close my browser, the Coin98 wallet locks and I have to enter the password again. Is this normal? Yes, this is standard security behavior. The extension is designed to lock after a period of inactivity or when the browser is closed to prevent unauthorized access if you leave your computer unattended. You can adjust the auto-lock timer in the extension's settings. Look for "Security" or "Auto-lock" settings. You can set it to lock after a specific number of minutes, but it will typically still lock upon browser closure. This is a protective feature, not a defect. For frequent use, ensure you have a strong but memorable password. My Coin98 extension icon is missing from the browser toolbar after installation. How do I get it back? This is a common issue and usually easy to fix. First, click the puzzle piece or extensions icon (usually in the top-right corner of Chrome, Edge, or Brave). Look for "Coin98 Wallet" in the list that appears. You should see a small pin or thumbtack icon next to it. If the icon is grey or un-pinned, click it. This will pin the Coin98 extension, making its icon visible on your main toolbar again. If you don't see Coin98 in the list at all, the installation may have failed or been blocked. Go back to the Chrome Web Store or your browser's extension store, ensure you're on the official Coin98 page, and try reinstalling. After a reinstall, remember to pin the extension.
