The Gas fee is charged by the Ethereum Mainnet, which StrongBlock does not collect or control.
- The gas can be estimated here: https://ethgasstation.info/ or https://etherscan.io/gastracker
Having insufficient ETH in your wallet can cause extremely high gas fees to be estimated.
- We recommend having at least $200-500 ETH in your wallet at all times to cover Ethereum Mainnet transaction gas fees.
