You need a device (computer or phone) with internet access and our app (for phones) or an up-to-date browser (for computers). The Exchange may not work on outdated browsers.

We are not responsible for malfunctions due to your device or third-party services you use outside our Exchange. We are also not responsible for the operation of services used by you outside our Exchange, even if you use them for transferring Crypto-assets.

We may temporarily disable all or part of the Exchange for maintenance, and will try to notify you in advance.

We may block access to certain or all Exchange functions if required by law, for individual Clients or jurisdictions.

You undertake to regularly verify and update the systems you use to access the Exchange. You acknowledge that failure to do so may affect the proper functioning of the Exchange on your device and may result in loss of profits or incurring losses.

  5. Transaction type (buy or sell),

We will confirm receipt of your Order, but this does not mean it has been executed.

If your Order is unacceptable, we will notify you with reasons.

The list of supported Crypto-assets is on our Website.

3.4. Execution of Exchange Orders

Execution occurs at the time indicated in the Transaction confirmation in your Client Profile.

Orders are executed at prices valid when the Order becomes final (cannot be withdrawn).

Our Website publishes the method for determining Crypto-asset prices.

The Table of Fees and Commissions may specify maximum/minimum Order values. Orders exceeding these limits may be rejected, cancelled or deemed invalid.

We may suspend Orders if access to a Crypto-asset is impossible for reasons beyond our control.

3.5. Restrictions and Liability for Orders

We may require additional documents or information to execute a Transaction, especially if required by third-party partners.

If, in accordance with applicable regulations, the exercise of rights, obligations, or other actions requires the transfer of your personal data or information concerning you that constitutes professional secrecy to a third party with whom we cooperate in providing Services, we will transfer such information, to which you hereby consent.

Only you are responsible for correctly transferring Crypto-assets to the appropriate wallets, including verifying whether the destination wallet you have indicated contains no errors and whether it belongs to you. An incorrect transfer of Crypto-assets or providing incorrect destination wallet details may result in the Crypto-assets being unrecoverable.

We may, with immediate effect, suspend the provision of Services in relation to a given Crypto-asset, in whole or in part, in cases where the provision has become impossible due to circumstances for which we are not responsible. We will exercise due diligence to inform you of this fact. The suspension of service provision lasts for the duration of the obstacle preventing the provision. If such an obstacle is permanent, our obligation to provide the Services expires in full.

Because of technical reasons, we do not guarantee that our list of purchase/sale offers is always up-to-date.

We are not liable for damages arising from:

  1. Order rejection,
  2. Suspension of Orders,
  3. Delayed settlement of Transactions due to reasons beyond our control.

3.6. Funds for Transactions

Our Website specifies methods for transferring money for Transactions.

You may use third-party services to transfer funds, subject to their terms.

You may also transfer funds for the purpose of making a Transaction via bank transfer. To do this, you must provide correct transfer details, including, among others, your name and surname, recipient, transfer title, and our account number. We are not responsible for transfers in which the details have been incorrectly filled out by you.

If a bank transfer is directed to your Wallet from an account that does not belong to you, you provide an incorrect transfer title, or you do not provide us with the information referred to in section 4 within the specified time, we will return the funds within 30 days at the sender’s cost and risk, to the bank account from which they were originally sent. We may deduct any handling fees corresponding to the cost of executing the return. If the amount to be returned is lower than the minimum handling fee, it will be fully deducted as handling costs.

Incoming transfers are updated in accordance with incoming transfer sessions on all days of the week except Saturdays, Sundays, and public holidays.

3.7. Funding the Wallet with Crypto-assets

If you fund your Wallet with Crypto-assets, you may do so only from a distributed ledger address or account belonging to you. Otherwise, we will return these Crypto-assets to the initiator of the transfer. The return will be made within 30 calendar days, and the amount of the return transfer will be reduced by the applicable network fee at the time of the return, as well as by our handling fee, which will depend on the quantity and type of the given Crypto-asset. If, due to missing or incorrect information, we are unable to return the Crypto-assets to you, we will ask you to provide the necessary information. If you do not do so within the deadline we specify, we will apply the appropriate procedure indicated in section 12. We are not responsible for any possible increase in the network fee depending on the timing of the return, nor for changes in the value of the given Crypto-asset.

If we have doubts as to the ownership of the distributed ledger address or account from which the Wallet was funded, we may apply the measures referred to in section 4.

3.8. Withdrawal of Funds

For bank transfer withdrawals, you must specify your own bank account. We will not process a withdrawal to any other bank account. Furthermore, we will not process a transfer if it does not contain all the required and correct information as required by applicable regulations.

Withdrawals are processed within 2 business days.

3.9. Withdrawal of Crypto-assets

Crypto-assets can only be withdrawn to your own distributed ledger address or Crypto-asset account.

3.10. Custody of Crypto-assets

Crypto-assets visible in your Wallet are stored and administered by an entity with which we have a relevant agreement.

4. Transaction Security

You may not use Exchange for purposes inconsistent with its intended use

If we have reasonable suspicion that your actions are unlawful—particularly if we suspect that the funds or Crypto-assets involved in a Transaction originate from an illegal source—we may block the Transaction or your Wallet. If, in such a case, we have received any funds, we may deposit them in an appropriate account or escrow until a final decision is reached, for which we will charge fees. The unblocking of funds or Crypto-assets may occur once all doubts have been resolved, including after obtaining relevant information from state authorities.

We may also block your Wallet if your data is incomplete or appears incorrect, and request additional documents.

If doubts cannot be resolved, we may refuse the Transaction. If we unblock your Wallet and execute the Transaction, you cannot claim for lost profits.

These rules also apply if a bank or other financial institution requests action.

We process your data for purposes related to the agreement, including maintaining the relationship, debt recovery, application processing, risk assessment, compliance, product and service development, and analysis.

Detailed data processing rules are in our Privacy Policy that you can find on our Website.

14. Death of the Client

When we obtain reliable information about the death of a Client, the agreement between us expires. We consider a scan of the death certificate, an abridged copy of the death certificate, or another official document confirming the Client’s death as reliable information.

After the agreement expires, we will block the ability to deposit or withdraw from the Wallet, and the Crypto-assets held in the Wallet will remain there until we receive appropriate instructions from the heirs of the deceased Client.

We accept any instructions regarding the Crypto-assets exclusively from the heirs indicated in a court decision confirming the acquisition of the inheritance or in a notarial deed of inheritance certification. In the case of multiple heirs, we may accept instructions from all of them or from one, provided that person acts on behalf of the others based on appropriate powers of attorney. We may also accept instructions based on a court decision on the division of the inheritance or an inheritance division agreement. If there are additional obligations arising from applicable regulations, we will execute the instructions after the heirs fulfill these conditions. In the case of multiple heirs, it is also necessary to provide an inheritance division agreement or a court decision on the division of the inheritance, indicating which persons are entitled to the Crypto-assets from the account and in what proportions.

Based on documents confirming the acquisition of inheritance and a scan of the heir’s identity document, we will accept a written instruction to transfer the Crypto-assets. Additionally, we may ask the heirs to provide proof that they are the owners of the account to which the Crypto-assets are to be transferred.

The above provisions apply accordingly in the case of the liquidation of a legal entity or an organizational unit without legal personality. In the case of liquidation, reliable information about the liquidation must be provided, which we consider to be a resolution of the partners on the dissolution of the legal entity, a court decision forming the basis for the dissolution of the legal entity, or an extract from the National Court Register confirming the liquidation of the legal entity..
