According to CoinMeta, Wu said that on August 28th, two major Korean cryptocurrency exchanges, Upbit and Bithumb, listed the early-stage token ICX as a trading warning asset and suspended related deposit and withdrawal services. Bithumb stated that the reason for the suspension was the identification of a security incident related to cryptocurrency wallets or distributed ledgers, with the specific cause yet to be determined or fixed. Early-stage N is a blockchain launched in 2017, and ICX is its native token, which was previously mainly used for network transactions, staking, and governance. Currently, early-stage N is in the process of migrating to the cross-chain DeFi infrastructure Sodax.
