On Ethereum the gas asset is ETH; on BNB Smart Chain it is BNB; on many Ethereum L2 networks gas is also paid in ETH. Holding USDT, USDC or another token does not automatically provide gas. Check the selected network, native-asset balance, transaction value and estimated fee before retrying. ## Key takeaways - Gas is paid with the native gas asset of the network, not with an arbitrary token balance. - A token transfer can fail to start even when the wallet shows a large token balance. - The required amount is roughly transaction value plus the wallet's maximum fee requirement. - ETH on Ethereum Mainnet and ETH on Base or Arbitrum are separate balances. - Fix the network/gas balance first; repeated signing does not create gas. ## 1. Token balance and gas balance are different Suppose an account has 1,000 USDC on Ethereum but 0 ETH. The USDC is valuable, but an ERC-20 transfer changes Ethereum state through a smart contract and requires gas. The account therefore needs ETH in addition to USDC. The same principle applies on other EVM chains. A token cannot pay the network fee unless the chain or wallet explicitly supports an alternative fee mechanism. For standard user flows, always identify the chain's gas asset first. ## 2. Why the wallet may require more than the displayed fee Ethereum wallets estimate gas and fee parameters before broadcasting. Under EIP-1559, a transaction can specify a maximum fee per gas and a priority fee. The final amount paid may be lower than the maximum reservation, but the sender still needs enough balance for the transaction to be valid under its fee limits. A simple ETH transfer has a lower gas requirement than many token or smart-contract interactions. Swaps, approvals and bridge transactions can consume more gas because they execute contract logic. ## 3. The wrong network is a common cause If you hold ETH on Ethereum Mainnet but the transaction is being sent on Base, the Mainnet balance cannot directly pay Base gas. The same address can appear on both networks while balances remain independent. Before adding more funds, confirm the network name and chain context. Sending gas to the wrong network can leave you with two funded balances but still no gas where the transaction needs it. ## Safe fix checklist 1. Confirm the network selected in the wallet/dApp. 2. Identify that network's native gas asset. 3. Check the native balance on a block explorer. 4. Review the transaction value and wallet fee estimate. 5. If the account lacks gas, obtain a small amount of the native asset on that exact network through a trusted route. 6. Retry only after the balance appears on the correct chain. Do not connect to an unknown “gas refill” website simply because an error message appears. Verify the domain and route independently. ## Common mistakes - Assuming a USDT/USDC balance can pay Ethereum gas. - Confusing ETH on Mainnet with ETH on an L2. - Sending BNB on the wrong chain variant. - Repeatedly clicking confirm without changing the native balance. - Using a random faucet or support link that asks for a seed phrase. ## How this works in Terenval Wallet Terenval Wallet separates supported networks in the network selector. If a transaction reports insufficient gas, verify the selected network and inspect the native asset balance for that exact network before signing again. Terenval's multi-network interface does not merge gas balances across Ethereum, Base, Arbitrum, BNB Smart Chain or other chains. A wallet can estimate and display a fee, but it cannot bypass a blockchain's requirement that the account have enough native gas value. ## Frequently asked questions ### Why can I not send USDT when I have USDT? Because the token balance and gas balance are separate. You generally need the network's native gas asset as well. ### Can ETH on Ethereum pay gas on Base? No. ETH balances are chain-specific. You need usable ETH on the Base network for Base gas. ### Does a failed transaction still use gas? If an Ethereum transaction is actually included and execution reverts, computation has still been performed and gas can be consumed. An error rejected before broadcast/inclusion is different. ## Sources - https://ethereum.org/developers/docs/gas/ - https://ethereum.org/developers/docs/transactions/ - https://eips.ethereum.org/EIPS/eip-1559 ## Editorial review Published by Terenval.
