Why are gas fees necessary?
Gas fees are required to process transactions and actions on the blockchain. They compensate the network’s validators for securing and maintaining the system.
Why can’t USDT/USDC pay for gas fees?
Each blockchain uses its native cryptocurrency for gas fees:
- ETH for Ethereum
- BNB for BNB Chain
- POL for Polygon, etc.
USDT and USDC are tokens on these networks but are not their native currencies, so they cannot be used to pay gas fees.
Why do I still see this error when I have enough gas?
The most common reason is that you don’t have enough gas tokens on the current network.
For example: You may have ETH on the Ethereum network, but you cannot use it to pay gas fees on the Arbitrum network.
Ensure you have enough gas tokens on the network you’re currently using.
What to do?
Option 1. Use Rabby's GasAccount feature. Learn more about it here: How does Rabby GasAccount work
Option 2. Acquire the network’s native currency (e.g., ETH, BNB):
- Buy it directly via your exchange.
- Transfer it from another wallet.
Once you have some native currency on the current network, you’ll be able to complete your transactions.
