Profile
AscendEX operates as a cryptocurrency exchange with its headquarters located in Singapore. The platform enables users to trade a variety of digital assets across multiple blockchain networks, including Ethereum, Binance Smart Chain, and Polygon. It provides spot trading services alongside custodial solutions that comprise both hot and cold wallet storage. Users can deposit, trade, and withdraw assets through the exchange’s interface.
The exchange is headquartered in Singapore. Its technical infrastructure is designed to support cross-chain transactions, reflecting a focus on interoperability within the crypto ecosystem.
In December 2021, AscendEX experienced a security breach in which approximately $77.7 million was moved from its hot wallets across the Ethereum, Binance Smart Chain, and Polygon chains. The company confirmed that its cold wallet holdings remained unaffected and promptly suspended withdrawals to investigate the incident. Response actions included contracting blockchain analytics firms, liaising with law enforcement agencies, and requesting other exchanges to blacklist the addresses associated with the stolen funds. AscendEX pledged to fully reimburse affected customers and subsequently restored withdrawal functionality in phases, beginning with Ethereum after completing infrastructure upgrades. Although normal operations were temporarily disrupted during the recovery period, the reimbursement guarantee ensured that no user funds were ultimately lost.
The incident highlighted the exchange’s reliance on hot wallet liquidity for active trading and underscored the importance of robust security measures for custodial assets. AscendEX’s commitment to compensating users and cooperating with external investigators demonstrates a particular approach to incident management within the cryptocurrency sector. The episode also illustrates how exchanges may engage with peers to mitigate the spread of illicit funds through address blacklisting initiatives.
