How to change gas fees on Coinbase Wallet? (Transaction Settings)

Understanding Gas Fees in Coinbase Wallet

1. Gas fees are network charges paid to Ethereum miners or validators for processing and confirming transactions on the blockchain.

2. Coinbase Wallet displays gas estimates automatically based on current network congestion and transaction complexity.

3. These fees fluctuate constantly due to demand on the Ethereum network and cannot be set arbitrarily low without risking transaction failure or extreme delays.

4. The wallet calculates three tiers: Low, Standard, and High — each corresponding to different confirmation time expectations.

5. Users retain full control over gas parameters only when using advanced mode, which exposes EIP-1559 fields like base fee and priority fee.

Accessing Transaction Settings Before Sending

1. Open Coinbase Wallet and navigate to the asset you wish to send — either via the “Send” button on the asset card or from the “Accounts” tab.

2. Enter the recipient’s address and the amount to transfer, then tap “Next” to proceed to the review screen.

3. On the review screen, locate and tap the “Gas fee” section — this opens the detailed transaction settings panel.

4. Toggle “Advanced” to reveal manual gas controls including max fee per gas (Gwei) and max priority fee per gas (Gwei).

5. Adjust sliders or input custom values while observing the estimated confirmation time and total fee shown in real time.

Modifying Gas Parameters Manually

1. In Advanced mode, the max fee per gas represents the highest amount you’re willing to pay per unit of gas, inclusive of both base and priority fees.

2. The max priority fee per gas determines how much extra you offer miners/validators as an incentive to prioritize your transaction.

3. Reducing the priority fee too far below current market rates may result in prolonged mempool queuing or eventual dropping of the transaction.

4. Increasing the max fee significantly above prevailing network conditions does not accelerate confirmation beyond what the priority fee already secures.

5. Values entered must comply with Ethereum’s EIP-1559 constraints — the max fee must always exceed the base fee estimate provided by the node.

Confirming and Submitting Altered Transactions

1. After adjusting gas settings, the wallet recalculates the total fee in ETH and displays it prominently alongside estimated confirmation time.

2. Review all fields carefully — especially recipient address, amount, and gas values — before proceeding.

3. Tap “Confirm” to sign the transaction locally using your device’s secure enclave or biometric authentication.

4. Once signed, the transaction is broadcast to the Ethereum network and appears in the “Activity” tab with status “Pending”.

5. You can monitor its progress using the block explorer link provided in the activity detail view.

Frequently Asked Questions

Q: Can I change gas fees after a transaction has been sent?No. Once signed and broadcast, gas parameters are immutable. The only option is to wait, replace with higher fee (if nonce allows), or let it expire.

Q: Why does Coinbase Wallet sometimes show “Not enough ETH for gas” even when I have ETH in my wallet?This occurs when the ETH balance is insufficient to cover both the transfer amount and the minimum required gas fee — particularly during high-congestion periods where base fees surge.

Q: Does changing gas fees affect ERC-20 token transfers differently than ETH transfers?No. All Ethereum-based transactions consume gas measured in units, and fee calculation follows identical EIP-1559 mechanics regardless of asset type.

Q: Are gas fee adjustments supported for networks other than Ethereum?Yes. Similar controls exist for Polygon, Arbitrum, Optimism, and Base — though fee structures vary. For non-EIP-1559 chains like BSC or Solana, Coinbase Wallet uses fixed or dynamic fee models instead of priority/base splits.
