On 25th of November, the LTC blockchain has been migrated to Lykke's new underlying exchange architecture Sirius. The migration has generated a new deposit address for each user.
Please make sure to use the new deposit address when making an LTC deposit from a third party platform to your Lykke account.
If you have saved the old LTC deposit address in any external device/system, please do update it to the new LTC deposit address. Otherwise, if you send LTC to the old address the new Miscellaneous section of the T&C will apply, there will be a service fee needed to be covered by the user.
