Why I am getting an "Insufficient Gas Fee" error?
When you make a transfer or swap on KuCoin Wallet, a pop-up windows appears with “Insufficient Gas Fee”. This means you do not have enough of your network's native token in your account to cover the cost of gas.
Generally, each transaction, including token and contract transactions, requires gas. You can think of this as a transaction fee. Gas is the unit of measure for how much computational work is required to process transactions and smart contracts.
The term is analogous to the gas that powers a car engine: it's the fluctuating, occasionally expensive cost of operation. More complex smart contracts require more gas to power their computation, just as a bigger, more powerful car takes more gas to run.
Examples of native tokens include:
- Ether (Ethereum mainnet, plus layer 2 networks such as Arbitrum or Optimism)
- BNB (for BNB Chain, formerly BSC)
- MATIC (Polygon)
- KCS (KCC)
How can I fix it?
You can remedy this by sending some of the necessary native token to that account in order to be able to make the transaction.
If you need to buy native tokens to reach a sufficient amount to make a transaction, you can either transfer the token to your wallet from an exchange like KuCoin, or swap other tokens to your desired native token on a decentralized exchange (DEX) through the bridge function.
