# Failed Transaction

### <mark style="color:blue;">**What to do when a transaction fails**</mark>

Sometimes, transactions on CC Swap may not go through as expected. Don’t worry — most issues are easy to fix. Here’s a quick guide on how to troubleshoot failed or stuck transactions and how to get help when you need it.

***

### ❌ <mark style="color:blue;">Common Reasons for Transaction Failure</mark>

1. **Insufficient Gas Fees**
   * Every transaction requires a small fee paid in the blockchain’s native token (e.g., CORE, ETH, BNB).
   * Low gas fees can result in pending or failed transactions.
2. **Slippage Too Low**
   * If your slippage tolerance is set too low, the price may change during confirmation, causing the transaction to revert.
3. **Token Approval Not Granted**
   * First-time swaps with a token require you to approve it before it can be used in a transaction.
4. **Network Congestion**
   * During peak times, transactions may take longer to confirm or fail due to block limits being hit.
5. **Wallet or Connection Issues**
   * A disconnected wallet or outdated browser extension can interfere with successful execution.

### ✅ <mark style="color:blue;">How to Fix It</mark>

**🔁 1. Resend with Higher Gas**

* If your transaction is pending, increase the gas limit or use your wallet’s "Speed Up" option.

**🛠 2. Increase Slippage Tolerance**

* In the settings menu (⚙️), try increasing slippage by 0.5–2% depending on the token’s volatility.

**🧼 3. Clear Pending Transactions**

* If your wallet is stuck, reset its nonce or clear pending transactions manually (MetaMask users can do this in settings).

**🔗 4. Check Blockchain Explorer**

* Use tools like [Corescan](https://scan.coredao.org/),  [Etherscan](https://etherscan.io) or [BscScan](https://bscscan.com) to see if the transaction failed or is still pending.

**🌐 5. Refresh & Reconnect**

* Refresh the CC Swap page, clear your browser cache, and reconnect your wallet.

***

### 🔒 Pro Tips for Avoiding Future Issues

* Always keep a small reserve of native gas tokens (e.g., CORE, ETH, BNB).
* Double-check token addresses from official sources.
* Use a stable internet connection and keep your wallet software updated.

**Stay safe. Swap smart. We’ve got your back.** 💪
