[Coinone] Notice of Termination of Trading Support: PORT3

Hello, this is Coinone.

Coinone has been supporting trading by strictly reviewing each virtual asset to foster a healthy virtual asset ecosystem.

In accordance with the 'Designation of Cautionary Assets and Trading Support Termination Policy', we inform you of the termination of trading support for PORT3 (PORT3, BNB Smart Chain).

Customers holding this virtual asset must read this notice and refer to it when using our services.

* Reference: Notice of Designation as a Cautionary Asset: PORT3

Reason for termination of trading support:

PORT3 was designated as a cautionary asset after a security incident occurred on November 23, 2025, and evidence of additional issuance was confirmed. We requested explanatory materials from the PORT3 side and conducted a thorough review, but no materials were found to demonstrate that the reasons for the designation as a cautionary asset had been resolved. Therefore, to protect users, we are terminating trading support for PORT3.

Key schedule

Termination of trading support: January 26, 2026 (Mon), 15:00

End of withdrawal support: February 26, 2026 (Thu), 15:00

Notes

• When trading a virtual asset for which trading support has been terminated, please be aware of the possibility of sharp price fluctuations.

• Deposits of the relevant virtual asset may be suspended when it is designated as a cautionary asset or when trading support is terminated. In such cases, we will notify you via a separate announcement.

• For virtual assets with terminated trading support, conversion to KRW value is not possible, and the Travel Rule applies in all cases. Therefore, withdrawals can be made only after entering additional recipient information or after the external wallet withdrawal address (whitelisting) has been approved.

• All unfilled orders after the termination of trading support will be canceled en masse.

• Existing transaction history will be retained even after the end of withdrawal support.

• To enable withdrawals after the termination of trading support, a deposit wallet address for the relevant virtual asset must be issued before the termination of trading support.

• The termination period may be shortened due to legal or regulatory requirements or other special circumstances. In this case, we will notify you via a separate announcement.

• Even after the withdrawal support period has ended, you can request a withdrawal through Coinone Customer Service. However, a fee may be charged for withdrawals of virtual assets that are not supported for trading. (Related link)

• Technical support such as mainnet changes, contract changes, airdrops, token swaps, and network updates may be suspended for virtual assets whose trading support has been terminated, which may result in a decrease or disappearance of the asset's value. Please be sure to withdraw all virtual assets within the withdrawal support period.

Coinone will continue to make every effort to ensure a healthy and transparent virtual asset ecosystem.

Thank you.

Sincerely,

Coinone Team
