&lt;div&gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;img  width: 750px;  iframe.movie  width: 750px; height: 450px; &amp;lt;br&amp;gt;Fix [https://extension-web3.com/core.php Core Wallet extension tutorial] wallet problems step by step guide&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Fix core wallet problems step by step guide&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;If your application is not connecting, check if the remote procedure call (RPC) URL is correct. A common mistake is using a deprecated endpoint (e.g., older Infura keys) or a rate-limited public node. Switch to a private RPC provider or run your own full node to reduce latency. For persistent connection drops, verify your firewall allows traffic on port 8545 (HTTP) or 8546 (WebSocket).&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;When you need to restore a wallet, never rely solely on a seed phrase screenshot–typos in phrase order or capitalization cause silent fails. Use your 12 or 24 words exactly as generated, and confirm the derivation path (e.g., m/44’/60’/0’/0 for Ethereum, or m/44’/118’/0’/0 for Cosmos). If the restored address still shows zero balance, you likely applied the wrong path or coin type. Export your keystore file instead of relying on seed phrases alone for reliability.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;The token not showing issue often stems from missing contract addresses. Manually add the token’s contract (from Etherscan or the official project repo) with the correct decimal count–typically 18, but USDC uses 6. If the token appears in a block explorer but not in your interface, clear the local cache and re-fetch via the token list API. For custom networks, ensure the token address is deployed on that specific chain (e.g., BSC vs. Polygon).&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Every transaction error message carries a revert reason. Enable full error logging: for MetaMask, use “hexData” in the console; for CLI tools, add --debug. A “revert” without reason indicates a require statement failure–often insufficient balance or a paused contract. For “out of gas” errors, your gas limit is too low: complex swaps need 150,000–200,000 units, not the default 21,000. Always estimate gas via the provider’s eth_estimateGas before broadcasting.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;If your dapp connection fails repeatedly, the site likely uses an outdated provider (e.g., window.ethereum deprecated in v2). Force a re-injection by clearing the browser’s site cache and reconnecting via “Connect Wallet” button. Test with a fresh incognito window to rule out extension conflicts. For mobile, check that the wallet app supports the dapp’s required chain ID–mismatches cause silent disconnections.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;When the client is not installing on Linux, missing system dependencies (libsecret, gnome-keyring) block the process. Install via the official binary, not through package managers like snap, which sandbox filesystem access. On Windows, run the installer as administrator and disable antivirus during setup–some heuristics flag crypto software as false positives. After installation, verify the binary’s SHA-256 hash against the official release page to confirm integrity.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Fix Core Wallet Problems: Step by Step Guide&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;If your application displays an error such as &amp;quot;not connecting&amp;quot; to a node, immediately switch the network endpoint in the settings to a public RPC URL (e.g., https://mainnet.infura.io/v3/YOUR_KEY) and clear the local cache under &amp;quot;Advanced Settings.&amp;quot; For a token not showing issue, manually import the token contract address via the &amp;quot;Manage Tokens&amp;quot; menu; verify the contract on a block explorer first. When the client is not installing, close all running processes, delete the temporary installation folder (usually C:\Users\[Name]\AppData\Local\Temp\CoreInstaller), disable antivirus real-time protection, and run the installer as Administrator. To reset account data without losing funds, navigate to &amp;quot;Settings &amp;gt; Reset Account&amp;quot; (this only clears cached transactions and balances, not your private keys). If a dapp connection fails, revoke all active sessions in the &amp;quot;Connected Sites&amp;quot; panel, restart the browser, and re-approve the request manually.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Not connecting: Change the node URL to a different provider (e.g., Alchemy or QuickNode) and restart the application–persistent failures indicate a firewall blocking port 443 or an outdated client version (update to the latest build).&amp;lt;br&amp;gt;Restore wallet: Use the &amp;quot;Import Wallet&amp;quot; feature with your 12-word seed phrase; if the error &amp;quot;invalid mnemonic&amp;quot; appears, check for typos in the phrase order and ensure no extra spaces.&amp;lt;br&amp;gt;Token not showing: For Ethereum-based assets, manually add the token contract address (commonly found on Etherscan) in the &amp;quot;Custom Tokens&amp;quot; tab; if it still does not appear, try switching the chain ID from 1 to 5 (Goerli testnet) and back.&amp;lt;br&amp;gt;Not installing: Ensure your OS meets the minimum requirements (Windows 10 64-bit, macOS 11 Big Sur, or Ubuntu 20.04); run the installer in compatibility mode if it fails–e.g., for Windows, right-click &amp;gt; Properties &amp;gt; Compatibility &amp;gt; Run as Windows 8.&amp;lt;br&amp;gt;Dapp connection: If the prompt fails to show, clear browser cache for the dapp’s domain, toggle &amp;quot;Allow Automatic Connection&amp;quot; off in settings, then refresh the page and manually connect via the dapp’s wallet selector.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Q&amp;amp;A:  &amp;lt;br&amp;gt;I tried to sync my wallet for two days and it’s still stuck at 99.9%. Is there a fast way to force it to finish without waiting another week?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;That final percentage point is often the hardest because the wallet is searching for the last few thousand blocks, which might be very recent or have complex transactions. Do not delete the entire blockchain data folder. Instead, close the wallet completely. Then, locate your blockchain data directory (common paths are `~/.bitcoin/blocks` on Linux or `%APPDATA%\Bitcoin\blocks` on Windows). Inside, find the `chainstate` folder and rename it to `chainstate_old` (this is safe because the wallet will rebuild it from the block data). Restart the wallet. It will now re-verify the last few blocks and quickly catch up. This usually takes 10–20 minutes instead of days. If the issue persists, your disk space might be too low for the UTXO database, or your system clock is incorrect.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;My wallet says &amp;quot;No block source available&amp;quot; even though I have a working internet connection. I checked my firewall and my router. What else could be broken?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;This error usually means the wallet lost its connection to the peer network. First, check your wallet’s debug console (if available) and type `getpeerinfo`. If the list is empty, your wallet cannot find active peers. A common fix is to edit your wallet’s configuration file. Open the `yourwallet.conf` file and add a static list of reliable public nodes. For example, add `addnode=68.183.234.43` or `addnode=seed.bitcoin.sipa.be` (using actual IPs from a trusted source). Save the file and restart the wallet. If that works, your DNS seeds might be blocked. A faster test is to manually connect using the command `addnode&lt;/div&gt;</summary>
