Hello, this is CoinUs.

This guide is about Ethereum withdrawal fee.

 * CoinUs is a decentralized wallet, and the withdrawal fee is used only for fees on the network.

(No fees paid to CoinUs)

Ethereum Network Fee = Gas Price * Gas ​​Limit

Gas Price

The unit of gas price is used in Gwei, 1 GWEI is equal to 0.000000001 ETH.

Mainly the gas price depends on the Ethereum transfer fee, which determines the network processing speed.

The higher the fee, the faster the transmission, and the lower the slower it is processed.

If the gas price is too low, it will only stay in the Mempool (block waiting state) and may not transfer.

In the case of CoinUs, you can reliably withdraw assets through the most optimized network fee in the current network we suggest.

If you want to modify a lower or higher fee than the fee suggested by CoinUs, you can always adjust your own settings.

Gas Limit

In the case of normal Ethereum transfer, the gas limit is 21000 by default, and smart contract transfer (including ERC20) has an individual gas limit for each smart contract.

The gas limit depends on the transmission type, but the value is fixed.

As the word limit indicates, the actual gas is used below the number.

Please note that if the gas limit is too small, transfer may fail due to out of gas.

If you enter the withdrawal address and quantity in CoinUs,

you do not need to set it up because you can see the size automatically.

Thank you.
