With Trust Wallet, you can send your funds anywhere they are supported. In principle, a small fee will always be required in one form or another before you can make transactions. Trust Wallet does not charge any fees, this is mandated by the blockchain or the network where a token resides.
On the Ethereum network, for a transaction to go through, miners need to approve it.
What is an ETH gas fee?
With Trust Wallet, we call these gas fees as Network Fee. And since these ERC20 tokens reside on the Ethereum Network, they require a certain amount of ETH to process the transaction. Trust Wallet setup the gas prices and gas limit automatically, but in some cases, users are also able to adjust them manually, according to their needs.
The fees are paid to the miners. If you need your transaction to be validated quickly, you can adjust to pay a higher gas price, so that validators (miners) are incentivized to verify your transaction before others. Similarly, setting a low gas price can cause your transaction to be stuck as miners won’t have any incentive to validate it.
The ETH Gas Tracker
You can check the current gas usage in the Ethereum Network via Ethereum Gas Tracker. There, you can get the recommended minimum gas fees to submit your transactions successfully.
