According to CoinMeta, HashKey Holdings Limited (3887.HK) announced that its licensed trading platform HashKey Exchange officially launched the functionality for depositing and withdrawing the regulated Hong Kong dollar stablecoin HKDAP on September 16, 2026, becoming one of the first licensed virtual asset trading platforms to support deposits and withdrawals of HKDAP. Qualified professional investors who meet the specified conditions can perform deposits and withdrawals through the verified whitelist wallet addresses provided by HashKey Exchange. Currently, HKDAP only supports deposits and withdrawals via the Ethereum (ERC-20) network. This move expands the applications of regulated Hong Kong dollar stablecoins beyond mere holding to a wider range of on-chain financial activities such as trading and payments.
