Terms of Service

Last updated: 12 August 2026

These Terms of Service ("Terms") govern your use of the GAC platform ("GAC", "the Platform"), operated by BuyCar.tech OÜ ("the Company", "we", "us"), a private limited company registered in Estonia under registry code 17094494, with its registered office at Harju maakond, Tallinn, Kesklinna linnaosa, Narva mnt 5, 10117, Estonia.

By creating an account or using the Platform, you confirm that you have read and accepted these Terms and our Privacy Policy. If you do not agree, do not use the Platform. If you have accepted these Terms in error, you must stop using the Platform.

1. What GAC is

GAC (Global Auto Chain) is a technology platform that lets users buy, sell and rent vehicles across borders. Every deal is locked in a smart contract on a public blockchain network: the funds move only when both sides have done what they agreed to. Settlement is in USDC or other acceptable stablecoin.

2. Eligibility

By accessing or using the Platform, you affirm that:

• you are at least 18 years old and legally able to enter into contracts;
• you comply with all laws, rules and regulations applicable to your use of the Platform, including those related to privacy, data protection, intellectual property and online conduct;
• you are not a restricted person: the Platform is not offered to and may not be used by persons or entities who reside in, are citizens of, are located in, are incorporated in, or have a registered office in Cuba, Iran, Syria, the Russian Federation, North Korea, the Crimea, Donetsk, Luhansk, Kherson or Zaporizhzhia regions of Ukraine, or any other territory to which the United States, the United Kingdom or the European Union embargoes goods or imposes similar sanctions. Circumventing these restrictions by any means, including the use of a VPN, is prohibited.

We reserve the right to verify your eligibility at any time, to request additional information or documentation for that purpose, and to suspend or terminate access where these requirements are not met.

3. Registration and accounts

An account is created with your email address. We verify it with a one-time code sent to that address — the Platform does not use or store passwords. Keeping access to your email inbox secure is therefore essential: anyone who controls your inbox can sign in as you.

At registration you choose an account type:

• Personal — for buying and renting vehicles. Free.
• Dealer — for businesses listing vehicles for sale or rent. A paid subscription (see Section 8); Dealer features activate once the subscription is set up.

To take part in deals you link a blockchain wallet to your account. The wallet is linked after registration (for Dealer accounts, after the subscription is set up). You are responsible for everything that happens under your account, including keeping your email and your wallet secure. We cannot recover a lost wallet, a lost private key or a lost seed phrase.

When you register you must provide accurate, complete and up-to-date information and keep it that way. Notify us at b.car.tech@proton.me if you believe your account has been compromised.

We do not verify the identity of users, except where such verification is explicitly provided as a separate service or required by applicable law. We may introduce identity verification (KYC) in the future; these Terms and the Privacy Policy will be updated before any such process starts.

4. Role of the Platform in transactions

The Company provides software infrastructure and may deploy smart contracts that users interact with when conducting transactions. The Company does not:

• participate in peer-to-peer transactions between users as a party;
• act as a payment service provider, broker, intermediary or escrow agent;
• provide custody of digital assets;
• control or hold users' private keys or wallets.

Users maintain control over their digital assets at all times and interact with blockchain networks through their own wallets. You acknowledge that:

• smart contracts operate autonomously — once predefined conditions are satisfied, they execute automatically;
• blockchain transactions are irreversible — once confirmed on-chain, neither you nor we can reverse, cancel or refund them;
• funds locked in a smart contract are held by the contract, not by us — we cannot move them outside the outcomes defined by the contract's published logic. Where a contract includes a dispute-resolution function, the Platform can execute that function only within the outcomes the contract allows;
• the blockchain is the source of truth — the state of a deal is determined by the smart contract, not by what any interface displays;
• blockchain networks may be congested, delayed, forked or otherwise unavailable, and we are not responsible for network-level failures.

The Platform may provide functionality allowing users to publish offers, discover counterparties or facilitate transaction matching. The Platform does not guarantee or enforce transactions between users. Users may communicate directly with counterparties to confirm transaction details; such communication may occur outside the Platform, and we do not monitor it and are not responsible for damages or losses arising from it.

5. Wallet interaction

The Platform does not and cannot access your private keys, passwords, or any assets held in your digital wallet. The Platform cannot initiate, reverse, cancel or otherwise modify any transaction that you independently authorise or execute through your wallet. The Company is not responsible or liable for how you use your digital wallet, including any actions, transactions, errors or losses resulting from such use.

The Company is not responsible for the actions or omissions of blockchain validators, node operators, wallet providers, blockchain networks, or third-party developers whose applications, protocols or services interact with blockchain networks. All such services are provided independently by third parties under their own terms.

6. Listings and dealer obligations

If you list a vehicle, you confirm that:

• you own the vehicle or are authorised to sell or rent it;
• the description, photos, condition, mileage, documents and availability are accurate and not misleading;
• the vehicle may lawfully be sold, rented and, where relevant, exported and imported;
• you hold every licence, registration and insurance required for your activity in your jurisdiction.

You are responsible for your own tax and regulatory compliance, including VAT, customs duties and any dealer licensing.

We may remove, pause or refuse any listing that we reasonably believe breaches these Terms or applicable law.

7. Rentals

Rental bookings are made for a date range and are subject to availability at the moment of booking.

• A security deposit is held by the smart contract and released back to the renter at the end of the rental in accordance with the contract.
• A platform fee of 9% of the rental price is non-refundable and is payable to the Platform.
• Early return is not recalculated automatically on-chain. If a rental ends earlier than booked, any refund for unused days is settled by the landlord directly, through support.
• If a defect is reported, the vehicle is paused and stays unavailable until the dealer marks it ready again.

8. Dealer subscription

The Dealer plan costs EUR 89 per month, billed by card through Stripe. Prices are exclusive of any applicable taxes unless stated otherwise.

• The subscription renews automatically each month until cancelled.
• You can cancel at any time through the Stripe billing portal available in your dashboard.
• Cancellation takes effect at the end of the period you have already paid for. There is no partial refund for the remaining days.
• Where a free trial is offered, cancelling before the trial ends means no charge is taken.
• After a subscription ends, you can no longer publish or re-publish listings, and your listings are removed from the public catalogue. Deals and rentals already in progress are not affected and run to completion.

Full details are in our Refund & Cancellation Policy.

We may change subscription prices with at least 30 days' notice before the change applies to your next renewal.

9. Fees and network costs

Beyond the subscription, the Platform charges per-deal fees, which are disclosed to you before you confirm a deal and are collected on-chain as part of the transaction. The 9% rental fee described in Section 7 is one of these fees.

Blockchain transactions also carry network (gas) fees required by the applicable blockchain network. These fees are determined by the network, are not controlled by the Company, and are non-refundable regardless of the outcome of the transaction.

10. Acceptable use

You must use the Platform solely for lawful purposes. You may not:

• use the Platform for money laundering, terrorist financing, sanctions evasion, fraud, phishing, spam, or any other unlawful, misleading or manipulative purpose;
• list stolen, encumbered or misrepresented vehicles;
• impersonate any person or entity, misrepresent an affiliation, or create accounts to circumvent a suspension;
• interfere with, disrupt, overload, probe, scan or otherwise compromise the security, integrity or proper functioning of the Platform, its systems, networks or infrastructure, including by introducing malware or any other harmful code;
• attempt to gain unauthorised access to any part of the Platform, user accounts, systems or data;
• use any robot, spider, scraper, parser or other automated means not provided by the Company to access the Platform or extract data;
• copy, reproduce, modify, distribute, sell, reverse-engineer, decompile or disassemble the Platform, its software or its content, except as permitted by law.

Any use of the Platform for unlawful, unauthorised or prohibited purposes constitutes a material breach of these Terms and may result in restriction, suspension or termination of your access.

11. Updates to the Platform

We may modify, add or remove features and content of the Platform at our discretion. During maintenance and bug fixing we may temporarily restrict or modify certain functionality. Continued use of the Platform after an update constitutes acceptance of the updated Platform.

12. Suspension and termination

We may suspend or terminate your access to the Platform, in whole or in part, if you breach these Terms, if we are required to do so by applicable law or a competent governmental authority, or if we reasonably suspect fraudulent or unlawful activity. Such suspension or termination does not constitute a breach of these Terms by the Company. Where possible, we will tell you why.

You may stop using the Platform and ask us to close your account at any time. Obligations arising from deals already in progress survive account closure, as do on-chain records, which cannot be deleted.

13. Intellectual property

The program code, design elements, text, graphics, software, trademarks and other content of the Platform are owned by BuyCar.tech OÜ or its licensors and are protected by the intellectual property legislation of the Republic of Estonia and international agreements and conventions. Subject to your compliance with these Terms, you are granted a limited, non-exclusive, non-sublicensable, revocable, non-transferable licence to use the Platform as intended, and nothing more. All rights not expressly granted are reserved by the Company.

Content you upload — photos, descriptions, documents — remains yours. By uploading it you grant us a licence to host, display and distribute it as needed to run the Platform, including in public listings.

If you believe content on the Platform infringes intellectual property rights, contact us at b.car.tech@proton.me with the supporting legal documents.

14. Personal data

We process personal data in accordance with applicable data protection laws, including the GDPR. What we collect, why, on what legal bases, for how long, and your rights are described in our Privacy Policy. Information about cookies and similar technologies is in our Cookie Policy.

15. Disclaimers

The Platform, its content and functionality are provided "as is" and "as available", without warranties of any kind except as required by the legislation of the Republic of Estonia. We do not warrant that the Platform will meet your requirements; that it will be available continuously, quickly, reliably and without errors; that defects will be corrected; that it is free from viruses or other harmful components; that it will be compatible with all devices, software or browsers; or that any information on it is current, complete or accurate.

We do not verify vehicles ourselves. Inspection reports, where used, come from third-party partners. We do not guarantee the conduct, solvency, identity or performance of any user, partner or counterparty. You are responsible for your own due diligence before entering a deal.

The use of the Platform is associated with the typical risks of data transmission over the Internet. We apply technical and organisational measures appropriate to the risk, but no method of transmission or storage is completely secure.

Nothing in these Terms excludes liability that cannot lawfully be excluded, including liability for death or personal injury caused by negligence, for fraud, or any mandatory consumer rights you have under Estonian or EU law.

16. Risk disclosure

Software only. The Company provides software. It does not provide financial, investment, legal, tax or other professional advice, and is not a broker, financial advisor, investment advisor, portfolio manager, tax advisor, crypto-asset service provider or custodian of any assets. Nothing on the Platform constitutes an offer or solicitation to buy or sell any currency, crypto-asset or other financial instrument, nor investment advice or a recommendation within the meaning of Regulation (EU) 2023/1114 (MiCA) or any other applicable EU law.

Crypto-asset risks. Crypto-assets are subject to high volatility and significant risks, including legislative changes, tax burdens, market fluctuations and other unpredictable factors. You may lose part or all of your crypto-assets.

Smart contract risks. Smart contracts are self-executing programs on blockchain networks. By using the Platform you acknowledge and accept the risks associated with smart contracts and blockchain technology, including vulnerabilities, bugs, third-party code dependencies, network failures, forks, malicious exploits and user errors that may result in partial or total loss of digital assets, and you agree that, to the maximum extent permitted by law, the Company shall not be liable for losses arising from interactions with smart contracts.

Lawful ownership. By accepting these Terms, you confirm that any crypto-assets you use through the Platform belong solely to you, were obtained lawfully, and are free of any third-party claims.

Security of devices. You are solely responsible for the technical condition and security of the devices you use to access the Platform, including protection against viruses, malware and unauthorised access.

17. Limitation of liability

To the maximum extent permitted by applicable law, we are not liable for indirect, incidental, special or consequential damages, loss of profit, loss of business, or loss of data, including where caused by:

• errors, malfunctions, interruptions or temporary suspension of the Platform;
• blockchain network behaviour, or the acts or omissions of validators, wallet providers or other third-party services;
• the loss of your wallet keys or unauthorised access to your email or wallet;
• the acts or omissions of your counterparty or any other user, including their breach of these Terms or the law;
• third-party services such as inspection, logistics or insurance partners;
• circumstances beyond our reasonable control.

To the maximum extent permitted by law, our total liability to you for any claim relating to the Platform is limited to the greater of (a) the fees you paid us in the twelve months before the claim arose, or (b) EUR 100.

18. Indemnification

You agree to indemnify and hold the Company harmless from any claim or demand, including reasonable attorneys' fees, made by any third party due to or arising out of (a) your breach of these Terms or the documents they incorporate by reference, or (b) your violation of any law or the rights of a third party. You are responsible for any breach of these Terms by your affiliates, agents or subcontractors as if it were your own breach.

The Company reserves the right, at your expense, to assume the exclusive defence and control of any matter for which you are required to indemnify us, and you agree to cooperate with our defence of such claims and not to settle any matter without our prior written consent.

19. External links

The Platform may contain links to external websites or content not operated or controlled by the Company. These Terms govern only the Platform. If you visit a linked site, you do so at your own risk and should review its terms and privacy policy; we do not endorse and are not responsible for third-party websites, their content, or their business practices.

20. Force majeure

The Company is not liable for delays, failures or interruptions in the operation of the Platform caused directly or indirectly by force majeure circumstances, such as war or military actions, natural disasters, disruptions in power supply or Internet networks, hardware or software failures, virus attacks, actions of governmental authorities, or any other circumstances beyond our control.

21. Changes to these Terms

We may update these Terms. If a change is material, we will notify registered users by email or in the app before it takes effect. The current version is always available at this address. Continuing to use the Platform after a change means you accept the updated Terms; if you disagree, you must stop using the Platform before the changes take effect.

22. Severability and assignment

If any provision of these Terms is found invalid or unenforceable, it will be limited or excluded to the minimum extent necessary, and the remaining provisions stay in force. A failure to enforce any provision is not a waiver of the right to enforce it later.

The Company may assign or delegate these Terms, in whole or in part, at any time. You may not assign or delegate any rights or obligations under these Terms without the Company's prior written consent.

23. Governing law and disputes

These Terms are governed by and interpreted in accordance with the laws of the Republic of Estonia, without regard to conflict-of-law rules.

Disputes shall first be addressed through good-faith negotiations: send your claim in writing to b.car.tech@proton.me; we respond within 30 calendar days. Disputes that cannot be resolved amicably will be submitted to the competent courts of Estonia.

If you are a consumer resident in the EU, you keep the protection of the mandatory laws of your country of residence and may also use the EU Online Dispute Resolution platform.
