According to CoinMeta, Wu said that South Korean cryptocurrency exchanges Upbit and Bithumb have announced that they will list the native token Waves of the public chain project Waves as a trading warning project. Waves was launched in 2016 and mainly supports token issuance, smart contracts, and decentralized applications. The two exchanges stated that security incidents such as hacker attacks related to Waves wallets or blockchain networks, whose causes have not yet been identified or resolved, may result in user losses. Currently, Upbit has suspended Waves top-ups, and the Waves withdrawal service on Bithumb was previously suspended. The two platforms are expected to decide between December 7th and 11th whether to extend the warning period, lift the warning, or terminate trading support.
