In September 2022, Ethereum is scheduled to start ETH 2.0's merge upgrade. To mitigate the risks caused by market volatility during the hard fork and safeguard users' assets, Gate.io temporarily listed two versions of $ETH. $ETHS (ETHPoS) represents the token for the new PoS (proof-of-stake) chain. $ETHW (ETHPoW) represents the token for the PoW (proof-of-work) chain that will potentially continue to exist.
If the ETH2.0 ends up with more than one chain, $ETHS will be automatically converted into the upgraded $ETH at a 1:1 ratio and the $ETHS will be delisted, and the PoW chain with the most hashrate will serve as the main chain of $ETHW. Gate.io will also support PoW chain resulting from the hard fork, and rename $ETHW in case the community requires us to do. But if this hard fork ends up failing, $ETH will be automatically converted into the updated $ETH, and the $ETHS and $ETHW will be delisted all together.
