How to change the transaction fee (Gwei) in Trust Wallet? (Gas Settings)

Accessing Gas Settings in Trust Wallet

1. Open the Trust Wallet application on your mobile device and ensure you are logged into your wallet.

2. Navigate to the Settings icon located in the top-right corner of the main screen.

3. Scroll down and select Wallet, then tap on Networks.

4. Choose the blockchain network you are using — for Ethereum-based transactions, select Ethereum or the relevant EVM-compatible chain like BSC or Polygon.

5. Tap on Gas Price (Gwei) to enter the manual gas configuration interface.

Manual Gas Adjustment Options

1. Trust Wallet provides three preset modes: Low, Standard, and High, each corresponding to a dynamically estimated Gwei value.

2. To override these defaults, toggle the Custom switch and input your desired Gwei value directly.

3. The minimum acceptable Gwei varies per network — Ethereum mainnet typically requires at least 15–20 Gwei during low congestion, while Polygon may function reliably at 30–50 Gwei.

4. Entering an excessively low Gwei may cause transactions to stall indefinitely in the mempool without confirmation.

5. Inputting an abnormally high Gwei does not accelerate confirmation beyond network block inclusion limits and unnecessarily inflates cost.

Transaction Confirmation and Gas Estimation

1. Before signing any transaction, Trust Wallet displays an estimated fee in ETH or native token alongside the selected Gwei and gas limit.

2. The gas limit is auto-calculated based on the smart contract interaction type — transfers use ~21,000 units, while token swaps or NFT mints often require 100,000–300,000 units.

3. Users cannot manually edit the gas limit in most standard transfer flows unless advanced mode is enabled via developer settings.

4. A red warning banner appears if the estimated Gwei falls below the network’s current minimal threshold for inclusion.

5. Transaction speed is determined by both Gwei and total fee — a higher Gwei increases priority, but only up to the next block’s base fee cap.

Impact of Network Congestion on Fee Selection

1. During peak activity — such as major token launches or NFT drops — Ethereum’s base fee spikes, pushing recommended Gwei values above 100.

2. Trust Wallet pulls real-time gas data from third-party APIs like Etherscan or Blocknative, which may lag by 15–30 seconds under extreme load.

3. On Layer 2 solutions like Arbitrum or Optimism, Gwei values remain stable but effective fees depend heavily on L1 batch submission costs.

4. BSC and Polygon exhibit lower volatility; however, sudden surges in DApp usage can temporarily inflate required Gwei by 200% or more.

5. Failed transactions due to insufficient gas do not refund the full amount — only unused gas is returned, while the executed portion is consumed.

Frequently Asked Questions

Q: Can I change Gwei after initiating a transaction?A: No. Once signed and broadcast, the transaction parameters including Gwei are immutable. You may attempt to replace it with a higher-fee transaction using the same nonce.

Q: Does Trust Wallet support EIP-1559 fee customization?A: Yes. For Ethereum and compatible chains, users can set both maxFeePerGas and maxPriorityFeePerGas separately when custom mode is active.

Q: Why does my transaction show “Pending” for over 30 minutes?A: This usually indicates the selected Gwei is below the current network minimum. Check live gas trackers and resubmit with updated parameters.

Q: Are gas fees charged in the token I’m sending or in ETH?A: Fees are always deducted in the native currency of the network — ETH on Ethereum, BNB on BSC, MATIC on Polygon — regardless of the token being transferred.
