Keplr Wallet Setup Guide Practical Usage Tips and Common Problem Solutions

Install the browser extension from the official Chrome Web Store or Firefox Add-ons portal. Before initiating the process, verify the extension's publisher is listed as "Chainapsis" to avoid fraudulent copies. A twelve or twenty-four word mnemonic phrase will be generated; this sequence is the absolute master key to your assets and should never be stored digitally. Write it on physical material and keep it secure.
After the initial creation, manually add specific blockchain networks like Osmosis, Juno, or Secret Network. Navigate to the extension's settings, find the "Manage Chain Connections" menu, and input the correct RPC and REST endpoints for the desired network. Using default endpoints can lead to slow performance; consider switching to reliable, public endpoints from community providers for improved speed.
For signing transactions, always check the fee denomination and amount. A common error is attempting to pay a gas fee in a token the network does not accept. Ensure you maintain a small balance of the native token (like ATOM for Cosmos Hub) for transaction fees. If a transaction stalls, use the extension's interface to clear pending transactions, which often resolves the issue.
When connecting to a dApp, a pop-up will request permission for a specific address. You can grant access to all compatible addresses in your extension or select individual ones. If the dApp does not recognize your balance, first confirm the correct network is both selected in the dApp's interface and added to your extension. Hard refreshing the dApp's webpage (Ctrl+Shift+R) frequently re-syncs the connection.
Q&A:

I'm new to Cosmos. Is Keplr safe to use and how do I create a wallet?

Keplr is a widely trusted wallet in the Cosmos ecosystem. To create one, visit the official Keplr website or get the browser extension from the Chrome Web Store. Click "Create new wallet." You'll be given a secret recovery phrase—this is your master key. Write it down on paper and store it securely. Never share it or store it digitally. Confirm the phrase, set a password for your local device, and your wallet will be ready. The password only protects access on that specific computer; the recovery phrase is the only way to restore your wallet if you switch devices or lose access.
I added my wallet but my ATOM balance shows zero. What did I do wrong?

This is common and usually means you've created a new, empty wallet address instead of importing your existing one. If you already held ATOM, you likely have a wallet from an exchange or another service. In Keplr, use the "Import existing wallet" option and enter your old recovery phrase. If you don't have a phrase, your assets are probably still on the exchange. You would need to withdraw them from the exchange directly to your new Keplr wallet extension tutorial deposit address. Creating a new wallet generates a fresh address with no transaction history.
Can I use Keplr on my mobile phone and desktop simultaneously?

Yes, you can use Keplr on multiple devices. The mobile app (available for iOS and Android) and the browser extension work separately. To sync your account, you must import it on each device using the same secret recovery phrase. The process is secure because your private keys are stored locally on each device. Your balance and activity will appear the same across devices as they are reading the same blockchain data. Just ensure you are using the official app from legitimate stores to avoid scams.
My transaction is stuck or failed. How do I fix this and am I going to lose my funds?

A stuck or failed transaction typically does not result in lost funds. The assets usually remain in your wallet. First, check a block explorer like Mintscan for your Cosmos address to see the transaction status. If it failed, the network might have been congested or the gas fee too low. In Keplr, you can often increase the gas fee for a pending transaction or simply try to send it again. Ensure you have a small amount of the native token (like ATOM for the Cosmos Hub) to pay for gas. If the interface seems frozen, clearing the browser cache or restarting the app can help.
