# Error Handling

#### **Common Errors and Solutions**

1. **Transaction Delays**
   * **Cause**: Network congestion on the source chain or Fabric.
   * **Solution**:
     * Check the transaction status on FabricScan or the originating chain’s block explorer.
     * If the transaction remains pending for an extended period, ensure you have enough gas fees in your wallet and retry.
2. **Failed Wrapping Transactions**
   * **Cause**: Insufficient funds, contract issues, or compliance flags.
   * **Solution**:
     * Verify that you have sufficient funds to cover gas fees.
     * Double-check the contract address of the asset being wrapped.
     * Resolve any flagged issues if notified by the Zipper UI.
3. **Failed Unwrapping Transactions**
   * **Cause**: Issues with zAssets or wallet misconfiguration.
   * **Solution**:
     * Ensure you are sending the correct zAsset from your Fabric wallet.
     * Confirm the destination wallet address on the original chain.
     * Retry the transaction after correcting any errors.
4. **Incorrect Wallet Address**
   * **Cause**: Inputting the wrong address during wrapping or unwrapping.
   * **Solution**:
     * Zipper transactions are irreversible. Always double-check wallet addresses before confirming.
     * Use copy-paste functions to reduce errors and verify against official sources.
5. **Unsupported Tokens**
   * **Cause**: Attempting to wrap or deposit an unverified or unsupported asset.
   * **Solution**:
     * Check the list of supported tokens on the Zipper website or Polyester exchange.
     * Avoid interacting with assets marked as unverified.
