Terms of Service

1. Acceptance of terms

By downloading, installing, or using the Services, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Services.

2. Self-custodial wallet

SUBFROST is self-custodial. Your recovery phrase, private keys, and PIN are generated and stored only on your device, and all signing happens on your device. We never take custody of your assets, never receive your keys, and cannot move, freeze, or recover your funds. You are solely responsible for safeguarding your recovery phrase and device. If you lose your recovery phrase, your funds cannot be recovered by anyone, including us.

3. Eligibility

You must be at least 18 years old, and able to form a binding contract, to use the Services. You may not use the Services if you are located in, or ordinarily resident in, a country or region subject to comprehensive U.S. sanctions, or if you are a person named on a U.S. sanctions list (including OFAC’s Specially Designated Nationals and Blocked Persons List) or owned or controlled by such a person. You are responsible for ensuring that your use of the Services is lawful where you are. Additional eligibility requirements for SUBFROST Pay are in Section 5.

4. Optional features

Certain features are optional, off by default, and may be limited to specific regions or platforms. These include cross-chain swaps (routed through a third-party exchange provider) and SUBFROST Pay, a set of regulated payment features (described in Section 5). SUBFROST Pay is provided together with our regulated payment, identity-verification and card-issuing partners, and requires identity verification (KYC/AML) and acceptance of those partners’ terms. Information collected for these features is described in our Privacy Policy. If you do not use a given feature, its terms and data collection do not apply to you. Cross-chain swaps and SUBFROST Pay are available only on Android and, where noted, the browser extension; neither is present in the iOS app.

5. SUBFROST Pay

SUBFROST Pay features, including buying bitcoin with a card and, where available, converting bitcoin assets into U.S. dollars for spending, are offered only to residents of the United States who are at least 18 years old. We do not offer or market SUBFROST Pay outside the United States. To use SUBFROST Pay you must:

• complete identity verification in your own legal name, using accurate, current information;
• reside in a U.S. state where the feature is supported;
• use SUBFROST Pay only for yourself, and not on behalf of any other person or business; and
• not use a VPN, proxy or other means to hide your location or to get around our eligibility, location or sanctions controls.

We may decline, suspend or close access to SUBFROST Pay, and may delay or refuse a transaction, where we or our partners reasonably believe it is necessary to comply with law (including anti-money-laundering and sanctions law), to prevent fraud, or to protect you or others. Our partners’ own terms, including any cardholder agreement, also apply to your use of their services.

6. Refunds and disputes

• Blockchain transactions are final. Once a transaction is signed on your device and broadcast, it cannot be reversed, cancelled or refunded by us or by anyone else. Network fees and protocol fees paid on a broadcast transaction are not refundable.
• Purchases from merchants. Refunds for goods or services bought with a SUBFROST Pay card are handled by the merchant under its own refund policy. A merchant refund is credited back to the account that funded the purchase.
• Unauthorized or incorrect card transactions. If you see a card transaction you did not authorize, or one that is wrong, contact us at [email protected] as soon as possible and in any case within 60 days of the transaction. Disputes are handled with our card-issuing partner under the cardholder agreement and applicable law.
• Buying bitcoin with a card. Card purchases of bitcoin are processed by our payment partner and are subject to its terms. Once the bitcoin has been delivered to your wallet, the purchase cannot be refunded.
• Service errors. If a SUBFROST Pay transaction fails or funds do not arrive as expected, contact [email protected] with the transaction details. We will investigate with our partners and tell you the outcome.

7. Crypto risk disclosure

Digital assets carry significant risk. Before using the Services, understand that:

• Prices are volatile. The value of bitcoin and other digital assets can rise or fall sharply, and you can lose some or all of the value you hold.
• No government protection. Digital assets are not legal tender and are not insured by the FDIC or SIPC. Balances held in your self-custodial wallet are not deposits.
• Transactions are irreversible. A transaction sent to the wrong address, or approved because of a scam, generally cannot be recovered.
• Wrapped and synthetic tokens. Tokens such as frBTC and frUSD depend on smart contracts, cross-chain bridges and signer networks. They may lose their peg or become unredeemable if those systems fail or are attacked.
• Technology risk. Smart contracts, blockchain networks and software, including ours, can have bugs, outages or congestion that delay transactions or cause loss.
• Fraud and scams. We will never ask for your recovery phrase, private keys or PIN. Anyone who does is attempting to steal your funds.
• Regulatory change. Laws and regulations that apply to digital assets may change and may limit or end the availability of some features.
• Taxes. Selling, swapping or spending digital assets may be a taxable event. You are responsible for your own taxes.

8. Assumption of risk

You understand and agree that:

• Use of the Services involves inherent risks associated with cryptocurrency, smart contracts, and blockchain technology, including volatility and total loss of value.
• We cannot guarantee the security of any blockchain network or smart contract, and blockchain transactions are generally irreversible.
• You are solely responsible for maintaining the security of your private keys, recovery phrase, and devices, and for every transaction you approve.

9. Disclaimer of warranties

The Services are provided “as is” and “as available” without warranties of any kind, whether express or implied. To the maximum extent permitted by law, Subzero Research Inc. disclaims all warranties, including but not limited to merchantability and fitness for a particular purpose; accuracy, reliability, or completeness of the Services; uninterrupted or error-free operation; and security against unauthorized access.

10. Limitation of liability

To the maximum extent permitted by law, Subzero Research Inc. shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of profits, data, or cryptocurrency assets, arising from or related to your use of the Services.

11. Third-party services

The Services may interact with third-party blockchain networks, protocols, and providers (such as Stripe and our other payment and card-issuing partners for SUBFROST Pay, and SimpleSwap for cross-chain swaps). We do not control and are not responsible for third-party services, and your use of them may be subject to their own terms and privacy policies.

12. Modifications

We reserve the right to modify or discontinue the Services at any time. We may also revise these Terms from time to time; material changes will be posted at this URL with a new “last updated” date. Your continued use of the Services after changes take effect constitutes acceptance of the revised Terms.
