Frequently Occurring Issues

We often encounter the following issues, so we'd like to share the solution:

  1. When gas fee appears as "0" or an extremely high value.

  2. When a decline message appears.

  3. When an RPC error occurs.

Solution: Delete the added network information below and set it up again as shown below.

- Network Name: Klaytn Mainnet
- New RPC URL: https://public-node-api.klaytnapi.com/v1/cypress
- Chain ID: 8217
- Currency Symbol: KLAY

When adding the network again, there may be cases where the Chain ID is not recognized. In such cases, you need to retry until it is recognized.

When sending another NFT after sending one, you also need to delete and add the network information again for a higher chance of success
