You can check the current gas fees on Mumbai Testnet by visiting a gas fee tracking website.
4. Set Appropriate Gas Limit:
Set an appropriate gas limit for your transaction to ensure that it gets processed successfully. If the gas limit is set too low, your transaction may fail. Conversely, if the gas limit is set too high, you may end up paying more in gas fees than necessary. It’s recommended to set the gas limit slightly higher than the estimated gas usage to avoid any issues.
5. Confirm Transaction Details:
Before confirming your transaction, double-check all the details such as the recipient address, the amount to be sent, and any additional data required. Once a transaction is initiated on the Mumbai Testnet, it cannot be reversed, so it’s important to ensure the accuracy of the details.
6. Wait for Confirmation:
After submitting your transaction, wait for it to be confirmed by the Mumbai Testnet network. The confirmation time may vary depending on the network congestion and gas fees. Once the transaction is confirmed, you can view it on the Mumbai Testnet explorer, which will provide you with the transaction hash and other details.
7. Troubleshooting:
If you encounter any issues during the transaction process, such as failed transactions or delays, you can seek help from the Mumbai Testnet community or forums. There are often experienced developers and users who can assist you in resolving the issue.
