In this guide, we address some of the most common issues you might encounter while using the 0xGassless platform and provide solutions to help you resolve them efficiently.

Connection Errors

Problem

You receive errors indicating that the application cannot connect to the blockchain network.

Possible Causes

• Incorrect RPC URL

• Network outages or disruptions

• Firewall or network restrictions

Solutions

1. Check RPC URL: Ensure that the RPC URL in your configuration file is correct.

   {
     "rpcUrl": "https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID"
   }

2. Network Status: Verify the status of the blockchain network you are trying to connect to. Use network monitoring tools or check the network’s official status page.

Transaction Failures

Problem

Transactions are failing consistently, either not being mined or getting reverted.

Possible Causes

• Insufficient gas limit or gas price

• Insufficient funds in the sponsoring account

Solutions

1. Gas Limit and Price: Adjust the gas limit and gas price in your configuration file. Ensure they are appropriate for the current network conditions.

   {
     "gasLimit": 8000000,
     "gasPrice": "20000000000"
   }

2. Check Account Balance: Ensure the account sponsoring the transactions has sufficient funds.

3. Verify Contract Addresses: Double-check the contract addresses you are interacting with to ensure they are correct and deployed on the correct network.

Configuration Errors
