Huobi issued a document "Explanation on Supporting ETH Potential Forks and Processing Plans", stating that it has an objective and neutral attitude towards split assets (including but not limited to ETH) created through hard forks. As long as the forked assets meet the security requirements, they will support Users hold assets and provide transaction services as soon as possible according to the rules. Among them, Huobi will support the distribution of assets on the ETH fork chain (including but not limited to mainnet coins) that meet the following conditions: 1. Notify Huobi in advance before the fork, and get a clear reply; 2. By default, it has strict two-way defense Replay attack protection, that is, transactions on one of the chains can be invalidated on another chain; 3, the new chain will not be overwritten or eliminated by the original chain; 4, transactions have different formats, so that all wallets (including lightweight Clients) need to be upgraded to support the new chain; 5. The official client software should be released before the hard fork is activated, and the client software must undergo public testing and evaluation.
