A low value (e.g., 21,000 for simple ETH transfers but often insufficient for contract interactions) will cause the transaction to fail with an error. For token swaps or deploying a contract, manually set the limit to 100,000–500,000 units. If you see “out of gas” notices, increase the limit in increments of 20,000 until the transaction confirms. Conversely, an excessively high limit (over 1,000,000) wastes fees without improving success rates.&lt;br&gt;&lt;br&gt;&lt;br&gt;Resolve a broken dapp connection by clearing your browser’s site data. Navigate to your browser’s settings, locate the storage section for your specific decentralized application URL (e.g., “metamask.io” or “uniswap.org”), and delete cookies, cache, and local storage. After this, reconnect your interface by scanning the connection QR code or clicking “[https://extension-web3.com/core-wallet-extension-security.php Connect Core Wallet to dApp]” again. If the issue persists, disable any VPNs or ad-blockers, as they frequently block WebSocket or RPC endpoints, resulting in total loss of dapp connection.&lt;br&gt;&lt;br&gt;&lt;br&gt;When a program is not installing, verify your operating system’s disk space and permissions. A common cause is less than 500 MB available on the system drive, which halts the installation process midway. On Windows, right-click the installer and select “Run as administrator”; on macOS, drag the app to the Applications folder from a downloaded DMG file, not a ZIP extracted to the desktop. If the installer still fails, check for conflicting antivirus software that may quarantine the binary–add an exception for the application’s folder.&lt;br&gt;&lt;br&gt;&lt;br&gt;If your node is not connecting to the network, examine the chain configuration file for incorrect RPC endpoints. Most clients rely on a `chain.json` or `config.toml` file. Ensure the “bootstrap_nodes” list contains active, up-to-date IP addresses (you can fetch these from the project’s official GitHub repository). A common mistake is using a deprecated port (e.g., 8080 instead of 30303 for UDP). Run a peer check command like `admin.peers` in the JavaScript console to confirm you have at least three connected peers; if zero, your firewall likely blocks incoming connections.&lt;br&gt;&lt;br&gt;&lt;br&gt;When tokens are token not showing in your asset list, you must manually add the contract address to your client. Obtain the correct contract address from a verified source like Etherscan or the project’s official documentation. Copy it, then in your interface, select “Import Tokens” or “Add Custom Token.” Ensure the token symbol (e.g., USDC, WBTC) and decimal count (typically 18, but check for 6 or 8) match the contract exactly. Mismatched decimals cause the balance to appear as zero or a distorted value. If the token not showing issue persists, check if your client version supports the token standard (e.g., ERC-20 vs. BEP-20).&lt;br&gt;&lt;br&gt;&lt;br&gt;To restore wallet from a backup phrase, use the dedicated recovery option in your application’s “Import” or “Restore” section. Type each word of your [12/18/24-word seed phrase] in the correct order, with spaces, and ensure the correct derivation path is selected (e.g., `m/44'/60'/0'/0/0` for Ethereum mainnet). If your backup was created with a passphrase, you must enter that exactly. A single typo in the seed phrase produces a different address set with zero balance. After recovery, do not sync from a snapshot–allow the client to download blocks from genesis to verify the entire transaction history, which prevents future error concerning missing historical data.&lt;br&gt;&lt;br&gt;Fix Core Wallet Issues Troubleshooting Guide&lt;br&gt;&lt;br&gt;If you see a persistent error during startup, first try a complete reset account function from the settings menu. This clears corrupted local transaction caches without affecting your private keys. Navigate to Settings -&gt; Advanced -&gt; Reset Account. After the reset, the application will resynchronize from the blockchain genesis block. This process typically resolves 90% of synchronization failures and &quot;not connecting&quot; statuses displayed on the network indicator.&lt;br&gt;&lt;br&gt;&lt;br&gt;Token not showing: Verify the contract address is correct by comparing it against the official block explorer. You must manually add the token contract via the &quot;Add Custom Token&quot; option, inputting the exact decimal count (e.g., 18 for most ERC-20 tokens). If the asset remains invisible, delete the token listing, fully close the application, and re-add it upon restart.&lt;br&gt;Gas limit errors: A transaction failing with &quot;out of gas&quot; requires you to increase the gas limit parameter manually. For complex smart contract interactions, set the gas limit to 200,000 units. For simple ETH transfers, 21,000 is sufficient. Never set a gas price above 200 Gwei unless the network is congested; this wastes funds without improving success rates.&lt;br&gt;&lt;br&gt;&lt;br&gt;When the software is not installing, check your antivirus quarantine folder. Security tools frequently flag blockchain binaries as false positives. Add the entire installation directory to your antivirus exclusion list, then run the installer as an administrator. If the setup still fails, download the package from a different mirror source to rule out file corruption during download.&lt;br&gt;&lt;br&gt;&lt;br&gt;Restore wallet from a mnemonic phrase: Ensure you enter all words in the correct sequence and lowercase, separated by single spaces. A single typo generates a different address. If the balance shows zero after restoration, verify you selected the correct derivation path (usually m/44'/60'/0'/0/0 for Ethereum-based platforms).&lt;br&gt;Not connecting to peers: Manually add seed nodes by editing the configuration file. Locate the peers.txt file in the appdata folder and append 3-4 public node addresses from a trusted community list. Disable UPnP in network settings if your router causes connectivity loops.&lt;br&gt;&lt;br&gt;&lt;br&gt;The restore wallet process via private key (hexadecimal) is more straightforward than using a seed phrase. Copy the key exactly, ensuring no leading or trailing spaces. If the application rejects the key, verify you are pasting into the correct field labeled &quot;Private Key&quot; and not the &quot;Keystore File&quot; import option. Immediate balance display confirms successful decryption.&lt;br&gt;&lt;br&gt;&lt;br&gt;For a persistent not connecting state on Windows, flush your DNS cache by running ipconfig /flushdns in Command Prompt, then restart the application. On macOS, delete the ~/Library/Application Support/YourAppName/ folder after backing up your keystore file. This removes outdated peer lists and forces a fresh network handshake. If the error persists, switch your network protocol from IPV6 to IPV4 in the application's advanced network tab.&lt;br&gt;&lt;br&gt;Q&amp;A: &lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;br&gt;</div>
