Today, on 1st of February, the BTC 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 BTC deposit from a third party platform to your Lykke account.
If you have saved the old BTC deposit address in any external device/system, please do update it to the new BTC deposit address. Otherwise, if you send BTC to the old address it may be lost. In this case, the new Miscellaneous section of the T&C will apply, and we will charge you a service fee to recover your funds.
