If you're experiencing issues with ENS and your wallet, this guide covers common troubleshooting steps for three widely used wallets:

If you’re having trouble sending or completing transactions with MetaMask, it may be due to their "Smart Transactions" feature, which is known to cause issues.

Even if you’ve previously turned it off, MetaMask updates can automatically re-enable Smart Transactions after an update.

To fix this:

This should restore normal behaviour.

Sometimes the Metamask-Ledger bridge loses contact with the Ledger device, resulting in transactions that are never prompted for confirmation on the Ledger device, or which show up in the Metamask UI as "pending" in perpetuity, and not broadcast and appearing on explorers like Etherscan.

These transactions are never broadcast onchain and needs to be cleared in Metamask (Settings → Advanced → Reset Account). See support.metamask.io/configure/accounts/resetting-your-account-in-the-event-of-a-stuck-or-pending-transaction/

Once you have cleared the stuck transactions, disconnect your Ledger device restart your browser. Finally, reconnect your Ledger and retry the transactions

MetaMask Wallet App gets its ENS name metadata from OpenSea APIs, which often lag in updating data from the blockchain. These delays can cause ENS names in MetaMask Wallet App to show up as "unknown". To fix this, follow the instructions to refresh metadata on OpenSea. Here is their guide: support.opensea.io/en/articles/9981745-why-is-my-nft-content-unavailable

If it doesn't show in your wallet, go to Assets → Refresh list, and manually import it using contract address: 0xC18360217D8F7Ab5e7c516566761Ea12Ce7F9D72. Here is their guide: support.metamask.io/manage-crypto/tokens/how-to-display-tokens-in-metamask/

MetaMask may overestimate gas if your balance is too low. Try adding more ETH and resending.

Update your hardware wallet, wallet app, and browser to the latest version.

Open Ethereum app on Ledger → Go to Settings → Blind signing → Enable it using both buttons. This must be re-enabled after each firmware update. Here is Ledgers guide: support.ledger.com/article/4405481324433-zd
