Notes

• Any items scheduled to be updated regarding supported virtual asset listings and trading support services will be updated before trading support begins, so please check.

• Trading support for scheduled virtual assets may be delayed or canceled due to circumstances of the asset issuer or Coinone's listing criteria.

• Under the Act on the Protection of Users of Virtual Assets, unfair trading practices (such as using undisclosed material information) are prohibited, so we ask for users' cooperation to maintain a sound market order for virtual asset trading.

• When a new virtual asset is listed for trading support, only limit sell orders are allowed for 5 minutes from the sell open time.

• If deposits come from virtual asset service providers not included in the Travel Rule solution integration list, it may take a long time until they are returned.

• Before depositing virtual assets, be sure to check the supported network and whether a memo or other secondary address is required to avoid mistaken deposits.

• In case of accidental deposits, you can request a return of the virtual asset according to Coinone Customer Center's accidental deposit return guide.
