[Coinone] Notice of Trading Support Termination: SLN

Hello, this is Coinone. Coinone has supported trading by strictly reviewing each virtual asset to create a healthy virtual asset ecosystem.

In accordance with the 'Designation of Cautionary Trading Items and Termination of Trading Support Policy', we are notifying the termination of trading support for Smart Layer (SLN, Smart Layer). Customers holding this virtual asset should check this notice and refer to it when using our services.

Reference: Notice of Designation as a Cautionary Trading Item: SLN

Reason for trading support termination: Smart Layer (SLN) was designated as a cautionary trading item because, as of September 3, 2025, important disclosures related to the virtual asset and a whitepaper explaining them were not confirmed, and when comprehensively considering trading and adoption status and the substance of the business, numerous insufficient aspects were identified that could cause user harm. Subsequently, we requested explanatory materials from Smart Layer and conducted a thorough review, but no materials were found that would indicate the reasons for designation had been resolved. Therefore, to protect users, we are terminating trading support for Smart Layer (SLN).

Key schedule

Trading support termination schedule: November 14, 2025 (Fri) 15:00

Withdrawal support end schedule: December 15, 2025 (Mon) 15:00

Notes

⁃ Deposits of the asset may be suspended upon designation as a cautionary trading item or upon termination of trading support. In such cases, we will notify you via a separate announcement.

⁃ For assets whose trading support has ended, it is impossible to convert their value into KRW, and the Travel Rule will apply in all cases. Therefore, you may need to enter recipient information additionally or withdraw after having an external wallet withdrawal address approved (whitelisting).

⁃ All unfilled orders after the trading support end date will be canceled in bulk.

⁃ Existing transaction history will be retained even after the withdrawal support end date.

⁃ You must issue a deposit wallet address for the asset before the trading support end date in order to be able to withdraw after the trading support end date.

⁃ During the process of terminating trading support, the termination period may be shortened due to legal or regulatory requirements or the occurrence of special circumstances. In such cases, we will notify you via a separate announcement.

• After the withdrawal support period has passed, you can still request withdrawals through the Coinone customer center. However, withdrawals of assets not supported for trading may incur a fee. (related link)

• For assets for which trading support has ended, technical support such as mainnet changes, contract changes, airdrops, token swaps, and network updates may be suspended, which may cause the asset's value to decline or disappear. Please make sure to withdraw all assets within the withdrawal support period.

Coinone will continue to do its best to promote a sound and transparent virtual asset ecosystem. Thank you.
