Upbit Flags Zilliqa (ZIL): What Traders Need to Know

In a move highlighting increased regulatory scrutiny, South Korea's prominent cryptocurrency exchange Upbit has added Zilliqa's ZIL token to its "Investment Caution" watchlist. The designation applies to both the ZIL/KRW and ZIL/BTC trading pairs. This action is a direct application of the country's newly enforced Virtual Asset User Protection Act, which mandates exchanges to proactively warn users about assets with potential security risks.

Core Concern: Undisclosed Network Vulnerabilities

Upbit's announcement indicates that its monitoring systems have detected potential, unverified security issues within the ZIL wallet infrastructure or its underlying distributed ledger. These vulnerabilities, which could stem from unresolved past incidents or undisclosed threats, pose a tangible risk of asset loss for users. The exchange framed the listing as a precautionary measure to safeguard its user base.

Watchlist Timeline and Potential Outcomes

The cautionary status for ZIL is set for an extended period:

  • Effective Date: July 22, 2026
  • Review Period End: Third week of August 2026 (estimated August 17-21)

During this timeframe, Upbit will conduct a thorough review based on its delisting policy. The process may conclude in one of three ways:

  • Removal from the watchlist if risks are mitigated.
  • Extension of the observation period.
  • Termination of trading support for ZIL on the platform.

Current Deposit/Withdrawal Status and Future Plans

Deposit and withdrawal services for ZIL were suspended prior to this announcement. Upbit outlined a cautious, phased approach for any potential restoration of services:

  • Withdrawals: Should services resume, enabling user withdrawals will be the top priority.
  • Deposits: The reinstatement of deposit functionality is pending further review and will require a separate notice.

The exchange explicitly warned that any new ZIL deposits attempted now will not be credited and will be automatically returned. Users are advised to avoid deposit attempts until an official update is provided.

For current ZIL holders on Upbit, the situation necessitates close attention to the exchange's evaluations over the coming years. This case underscores how regulatory frameworks are pushing exchanges to intensify their technical due diligence on listed projects.
