Definitions and role of the partners

Art. 4. For the purposes of these Terms:

• "USDC" is a digital dollar (stablecoin) issued by Circle Internet Group and backed 1:1 by reserves;
• a "Wallet" is the crypto wallet in which the client receives crypto assets: a wallet address controlled by the client (own wallet) or, at the client's option, a self-custodied in-app wallet created for the client through the infrastructure of Privy Inc. The private keys are controlled solely by the client. The Company has no access to them, does not hold client funds and cannot order transactions on the client's behalf;
• a "Virtual account" is an account in the client's own name (EUR IBAN for SEPA transfers, USD details for ACH and wire transfers) issued by Noah. For clients in the European Union the account is issued by Noah LV SIA (Latvia), authorised by Latvijas Banka (the central bank of Latvia) as a crypto-asset service provider under Regulation (EU) 2023/1114 (MiCA) and as a payment institution under Directive (EU) 2015/2366 (PSD2), with the right to provide services across the EU; for clients in the United States it is issued by Noah US, Inc., a licensed money transmitter, NMLS #2696057 (together "Noah"). Funds received on the virtual account are converted into USDC, Bitcoin (BTC) or Ether (ETH), as chosen by the client, and delivered to the client's Wallet;
• the Platform is operated by the Company. Payment services, accounts, the conversion of fiat funds into crypto assets and back, and the related identification and anti-money-laundering checks are provided by Noah. Noah is not a bank. By completing onboarding the client also accepts Noah's applicable terms.

Exchange provisions

Art. 5. The Platform allows the client to: (1) receive EUR and USD on virtual accounts in their own name, from their own accounts and, where Noah permits, from third parties, converted into USDC, BTC or ETH and delivered to their Wallet; (2) sell crypto assets, withdraw funds and make payments (off-ramp) by sending USDC, BTC or ETH to a deposit address provided through the Platform, after which Noah converts them and pays the proceeds to a bank account in the client's own name or, where Noah permits, of a third party the client has registered as a recipient; (3) send and receive supported crypto assets over blockchain networks through the in-app Wallet. The Company reserves the right to add and remove assets, currencies and networks.

Art. 6. The services are used solely through:

• the Platform at xchange.bg;
• the client contact email: [email protected].

xChange.bg does not use commercial representatives and does not accept orders through other websites, social networks or messengers. The Company is not liable for orders placed outside the official channels.

Art. 7. Rates are calculated in real time at the moment of the transaction. For incoming transfers, the moment of the transaction is when the funds are credited to the client's virtual account; for sales and withdrawals, the moment the respective amount of crypto assets is received at the deposit address. Conversions between fiat currencies and crypto assets are carried out by Noah.

Art. 8. The Wallet is funded by:

1. SEPA bank transfer in EUR to the client's virtual IBAN;
2. ACH or wire transfer in USD to the client's USD details;
3. an incoming transfer of supported crypto assets to the client's Wallet address.

Art. 9. Withdrawals are made by: (1) transfer through Noah to a bank account of the client or, where Noah permits, of a recipient the client has registered (SEPA for EUR; ACH or wire for USD). The client is responsible for the accuracy of the recipient details and for the purpose of the payment. Noah may request additional information, delay or refuse a payment; (2) sending crypto assets to an address specified by the client, with the network fee borne by the client.

Art. 10. Owing to the volatility of crypto assets, the price at the time of the order may differ from the price at the moment the transaction is executed.

Art. 11. The Company is not liable for erroneously executed transactions or incorrectly provided details, including an incorrect wallet address. Crypto transfers are technically irreversible and in practice cannot be reversed. The client must carefully verify addresses and details before confirming.

Art. 12. The Company and its partners reserve the right to withhold execution of any operation they consider suspicious until the circumstances are clarified, and to request additional information and documents in accordance with applicable anti-money-laundering legislation.

Art. 13. Execution times: incoming transfers are normally converted and delivered to the Wallet on the same business day after receipt; withdrawals to a bank account are normally executed the same or the next business day; on-chain operations are executed after the required number of network confirmations. The Company is not liable for delays caused by banks, partners, blockchain networks or other third parties, nor for lack of liquidity caused by third parties. Where possible, the Company will notify clients of factors impeding timely execution.

Art. 14. The minimum amounts for each operation are visible in the Platform interface at the time the order is created.

Art. 15. The client's transfers must correspond exactly to the created order: the exact amount when funding and the exact quantity when selling. Otherwise the Company is not liable for delayed execution and rate changes.

Art. 16. Use of the services requires successfully completed identification (KYC for individuals, KYB for legal entities), performed by Noah and its identity-verification providers. The Company and its partners may request information and documents on the origin of funds in accordance with applicable law. The services are not provided to persons from sanctioned jurisdictions or to persons who do not pass verification.

Art. 17. When executing orders, the Company uses the data submitted by the applicants as provided and is not liable if the data prove inaccurate, misleading or untrue.

Return policy

Art. 18. The services are financial services whose price depends on fluctuations of the financial market, and therefore the statutory right of withdrawal does not apply. A client wishing to reverse an operation may do so at the current rate at the moment of the reverse operation. Crypto transaction fees and bank transfer fees are borne by the client.

Prohibited uses

Art. 19. The xChange.bg service may not be used to violate or circumvent tax or financial legislation, nor for actions related to money laundering or the financing of terrorist organisations.

Art. 20. The client bears full responsibility for the use of false information, program code or equipment intended to interrupt, obstruct, disturb or restrict the normal functioning of the Platform, or to gain unauthorised access to data or resources related to the service. In case of an established violation, the Company reserves the right to provide all available information about the client to the competent authorities, to cancel orders of clients identified as suspicious and to reverse payments received from or made to them where technically possible.

Limitation of liability

Art. 21. The Company is not liable for any technical problems or damages arising from software, computer equipment, internet connectivity, inadequate conduct of a client or of third parties performing unlawful actions, or from unforeseeable or extraordinary circumstances. The Company is not liable for actions performed through the profile of a client who has not exercised due care for the security of their access, including access to the email address used for sign-in, their devices and their configured multi-factor authentication methods. The client acknowledges that with the self-custodied in-app wallet, loss of control over the email address and recovery methods may result in permanent loss of access to the funds.

Art. 22. The Company is not liable for the reliability and operating conditions of the partners and blockchain networks whose services clients use when carrying out operations. Clients should acquaint themselves with the terms of the respective partners.

Art. 23. The Company does not provide investment advice. Crypto assets involve risk, including the risk of a total loss of value. Information on all fees is published on the Pricing page of the Platform.

Reserved rights

Art. 24. The Company reserves the right to publish advertising materials on the Platform as it sees fit and is not responsible for their content, insofar as it is owned by the advertisers and does not constitute an obvious violation of the law.

Art. 25. The Company reserves the right at any time and without notice to change the content, design, technologies and functionality of the Platform and is not liable for damages resulting from changed or discontinued functionality.

Final provisions

Art. 26. Complaints and enquiries are submitted to [email protected]. In the event of a dispute which the parties cannot resolve by negotiation, they agree that it shall be settled under the laws in force in the Republic of Bulgaria.
