Terms of Service

1.Who we are and what these terms cover

zerofive at z5.gg is operated by ZeroFive, established in Hong Kong, with its registered address at Hong Kong (full address to follow). These terms form the agreement between that company and the merchant using the service, and with customers who pay through our checkout for the sections that apply to them. If you act for a business, you must have authority to bind it.

By opening an account or using the service after accepting these terms, you agree to them, the Prohibited Businesses policy at /prohibited and the AML and KYC Policy at /aml. Our Privacy Policy at /privacy explains how we handle personal data.

We provide invoices, hosted checkout, prepaid subscriptions, tip pages and overlays, customer deposit addresses, and tools for payouts and refunds. Available coins and networks are those shown in the checkout or API at the time. Test balances and simulated transactions have no monetary value.

If you are paying a merchant, the payment, crypto risk, screening and governing law and disputes sections below apply to your use of our checkout. Your purchase is from the merchant. The merchant is responsible for what it sells, delivery, cancellations and customer refunds. These terms do not remove any consumer rights that apply by law.

2.Who can use zerofive

• You must be at least 18 and able to enter a binding agreement. Merchant accounts are for lawful business or professional use.
• You must not be a sanctioned person, be owned or controlled by a sanctioned person, or act for one. This includes anyone on the sanctions lists of the United Nations Security Council, the European Union or the US Treasury's Office of Foreign Assets Control (OFAC). Do not use the service to evade sanctions or other restrictions.
• We do not provide service to people or businesses located in Cuba, Iran, North Korea, Russia or Belarus, or in Crimea, Sevastopol, Donetsk or Luhansk, or in other countries or regions we block. This applies to merchants and to the customers who pay them. This is our access policy; it is not a statement that every transaction involving those places is illegal.
• Because of the EU's restrictions on crypto-asset services for Russia and Belarus, we do not open merchant accounts, hold balances or provide wallet services for Russian or Belarusian nationals or residents, or for businesses established in Russia or Belarus.
• You must hold any licences and permissions your business needs, and receive our written approval before accepting payments for a restricted activity listed at /prohibited.

Give us accurate account and business information and keep it current. We may verify your business and the people who own or control it, and request information about your business, customers, transactions or source of funds, when needed to assess eligibility or investigate risk. The AML and KYC Policy at /aml describes what we may ask for. We may limit live payments until a review is complete. Do not disguise your location, ownership or business activity.

3.Your account and security

Protect your password, email account, two-factor authentication, recovery codes, API keys and webhook secrets. Use the available security controls and give team members and API keys only the access they need. You are responsible for the instructions your authorised users and integrations send.

Review team permissions, saved payout addresses and API access regularly. Remove access when someone leaves. Keep live and test credentials separate. Never put a secret API key in browser code or share a private overlay link publicly.

Tell [email protected] promptly if you suspect unauthorised access. Revoke affected keys and secure your account. We may pause access or transfers to limit harm. A transaction already sent to a blockchain generally cannot be stopped.

4.How a payment becomes paid

1. Choose the coin and network shown at checkout. A quote fixes the rate until its displayed expiry, normally 30 minutes and never beyond the invoice's expiry. Send to the exact address shown on that network.
2. A detected transfer is still confirming. We credit it only after the required network confirmations and any screening or review. Merchants should fulfil an invoice on invoice.paid, and credit customer deposits on deposit.confirmed, after verifying the event on their server.
3. The standard short-payment tolerance is 0.5% of the invoice amount. A larger shortfall leaves the invoice partially paid. Further payments to the same address add up. A partially paid invoice does not expire automatically. The fee is based on the actual incoming payment.
4. If a payment is mined after the quote expires, it is valued at its arrival rate instead of the expired quote. That can leave a shortfall. Obtain a fresh quote before sending after expiry.
5. Open and pending invoices expire at the time shown. Their addresses remain watched for seven more days. An eligible payment detected in that window can still be credited and can make an expired invoice paid. Do not rely on recovery after that window.

Payments more than 1% above the invoice amount are marked as overpayments. The whole eligible payment is credited to the merchant, less our incoming fee. Returning the extra follows the refund rules below.

Customer deposit addresses can be reused while the service supports them. Deposits worth less than US$0.10 are treated as dust and ignored. Keep your own customer ledger: the balance held by zerofive belongs to the merchant account, not a separate account opened by each customer.

Subscriptions are prepaid. We do not pull later payments from a customer's wallet. Renewal invoices must be paid to extend the paid period. Canceling a subscription does not automatically refund time already paid for; the merchant handles that decision and any rights required by law.

5.Fees

Our standard processing fee is 0.5% of each incoming payment, including customer deposits and tips. We deduct it in the same coin when we credit the merchant's balance. A 100 USDT payment adds 99.5 USDT. A different rate applies only if we agree it with you.

There is no separate platform fee for withdrawals, payouts or refunds. We pay the network fee for those transfers. Network minimums, balance requirements and review limits still apply. The sender's wallet or exchange may charge for an incoming transfer.

Top-ups to your own merchant balance are free to add. If that top-up money later leaves the platform, we charge the 0.5% processing fee on that portion then. Transfers use money that has already paid the fee first. The same funds are not charged twice. This deferred processing fee also applies when top-up funds are used for a payout, withdrawal or refund.

We do not return the original processing fee when a payment is refunded. Any merchant fee for handling an overpayment is separate and must be disclosed to the customer.

We will give at least 30 days notice by email or in your dashboard before changing your fees. Changes apply prospectively from the stated date. You may stop using the service before then, subject to outstanding obligations and lawful holds.

6.We hold the funds

Your recorded balance is a claim against us for the relevant crypto amount, subject to these terms and applicable law. It is not a bank deposit, pays no interest and is not represented as covered by a bank deposit guarantee. If we cannot meet our obligations, you may lose funds or face delays in recovering them.

Balances are kept by coin and network. We do not convert them into fiat or automatically exchange one coin for another. A dollar value shown in the dashboard is a valuation, not a promise that you can redeem crypto for that amount of dollars.

Withdraw only to an address you control or are authorised to use. Payouts, withdrawals and refunds require enough available balance in the relevant coin and network. Minimum amounts, destination checks, issuer freezes, platform reviews and store suspension can prevent or delay a transfer.

7.Refunds and overpayments

Merchants decide and fund customer refunds, subject to applicable law. Ask the customer for a valid refund address on the correct network. Do not assume their sending address can accept a refund; it may belong to an exchange. Refunds are paid from the merchant's balance in the original coin and network, using the first paid coin if an invoice received more than one.

Where the merchant enables it, the payer can request an overpayment refund through checkout within 30 days after the invoice was paid. There is one request per invoice, and all payments must have used the quoted coin and network. The payer must use the original browser or the claim link in their receipt email.

The merchant can enable automatic overpayment refunds, require review, or turn off the self-service option. The default handling fee kept by the merchant is 1% of the extra, with a US$1 minimum. The amount returned must meet the network minimum after this fee. The checkout shows the applicable fee before the request. If self-service is unavailable, contact the merchant; that does not remove any legal right to a refund.

Refunds remain subject to screening and platform limits. After an invoice has a refund, it cannot be quoted or made paid again. Further eligible transfers may still credit the merchant but do not reopen the invoice. Ask for a new invoice before paying again.

8.Crypto risks

• Blockchain transfers are generally irreversible. A wrong address, wrong network or unsupported token can cause permanent loss. We cannot promise recovery.
• Crypto prices can change sharply. Stablecoins can lose their peg, and issuers can freeze or restrict tokens. A valuation or quote is not investment advice or a guarantee of value.
• Networks can become congested, stop, reorganise transactions or suffer attacks. Wallets, smart contracts, bridges and infrastructure providers can fail. Confirmations reduce some risks but do not remove them.
• A token symbol alone does not identify a token. Check the network and contract or token version. Supported bridged versions may share a balance label, and a payout may use a supported bridged version when the standard version is unavailable. The API identifies it with bridged_token. Check that the destination accepts that version before arranging the payout.

9.Screening, holds and declined payments

We screen live transfers using OFAC address data, token issuer restrictions including Tether and Circle blacklists, frozen token status and our own address restrictions. The AML and KYC Policy at /aml describes these checks and our monitoring. Screening is a risk control, not a guarantee that a payment is lawful or safe.

We also screen the people involved, against the consolidated sanctions lists of the UN Security Council, the European Union and OFAC. Merchant store names and the names of team members are screened within minutes of an account being opened or a name changing, and again whenever the lists are updated. Before a live payment is credited, we screen the customer name the merchant gives us, if any, and the country the customer or the merchant gives for them. If there is a name to check and our copy of a list is missing or out of date, we do not credit the payment until it can be screened.

Our hosted pages and API are not served to connections from countries and regions we block, where we can locate them. A payment sent directly on a blockchain carries no location, so it is screened by its sending address and by the name and country given for the customer. We record each screening decision: what was checked, against which versions of the lists, and the outcome.

A possible sanctions match is reviewed by us before we treat it as confirmed. During the review we may suspend the merchant account, hold the payment or refuse the transfer. If we confirm that funds come from, belong to or would go to a sanctioned person or wallet, we keep them blocked, do not credit, release or return them except where the law or a licence from the competent authority allows it, and report them to the competent authorities, such as OFAC or the authority of the relevant EU member state, within the time the law requires.

A flagged incoming payment is held without credit to the merchant while we review it. If cleared, it can be credited normally. If declined, it is not credited and may cancel an otherwise unpaid invoice. We also refuse outgoing transfers to restricted destinations.

Large live payments can wait through an additional screening period after network confirmation. The standard setting is about one hour for payments worth US$1,000 or more. This is not a maximum review time. Stores that quickly pass incoming money through to other wallets, or show other risk indicators, may have payouts held for review.

New stores: during a store's first 30 days of taking live payments, each customer payment can be withdrawn, paid out or refunded only after a waiting period, currently 72 hours for payments received in the first 7 days and 24 hours after that. Top-ups are not affected. We may shorten, extend or lift this period for a store based on its risk.

We may request supporting information, restrict addresses or accounts, and report or disclose information where required by law. We will explain a hold when we can, but legal or security restrictions may limit what we can share. A hold or screening match is not by itself a finding that someone committed an offence.

10.Your responsibilities to customers

• Describe your business, prices, goods and services accurately. Publish clear delivery, cancellation, subscription and refund terms and a way to contact you.
• Fulfil purchases, answer complaints and honour required refunds. You remain responsible for your customers' balances and for reconciling them with confirmed payments and payouts.
• Determine, collect, report and pay taxes that apply to your business. Our records or reports do not replace your tax obligations.
• Use the service lawfully and follow /prohibited. Do not process undisclosed third-party businesses or misrepresent the source or purpose of a payment.
• Have a lawful basis to share customer information with us. Give customers appropriate privacy information, keep submitted data accurate and avoid including unnecessary sensitive information in metadata or messages.

11.API, webhooks, tips and overlays

Follow documented rate limits, authenticate webhooks and handle retries without processing the same event twice. Verify payment status on your server. A browser redirect, screenshot or detected-payment event is not proof that funds are available.

Do not use the API, checkout, emails or tip messages for spam, malware, harassment, unauthorised access or attempts to bypass security and risk controls. Do not overload the service or evade limits with multiple keys or accounts. We may limit abusive traffic.

You are responsible for your tip page and the content you display in an OBS overlay or broadcast. Tell supporters when their name, amount or message may be public. Moderate unlawful or abusive content, obtain necessary permissions and protect private overlay links. A tip is not a tax-deductible donation merely because it is called a donation.

12.Suspension and closing an account

We may restrict, suspend or close a store for a breach of these terms, prohibited activity, suspected fraud, security risks, missing review information or a legal requirement. Where practical and lawful, we will explain the issue and give you a chance to resolve it. Urgent restrictions may take effect immediately.

During suspension, checkout and new payment activity can be blocked and payouts paused. We cannot stop someone sending to a known blockchain address. Money that arrives may be held without becoming available to the store. Do not invite further payments while suspended.

You may request closure through [email protected]. Stop new sales through zerofive, resolve customer obligations and request withdrawal of your available balance. Closing an account does not cancel pending transfers, erase financial, verification or screening records, or release restricted funds. The retention schedule in the Privacy Policy at /privacy applies.

On closure, we will arrange withdrawal of any balance that can lawfully be released, after outstanding fees, authorised refunds and other amounts properly due are accounted for. Reviews, network minimums and legal restrictions may delay release. Suspension or closure alone does not forfeit your balance. We will review continuing restrictions when new information allows.

Payment obligations, lawful holds and the provisions needed to resolve disputes continue after closure. Contact [email protected] if you want us to review a suspension or balance restriction.

13.Availability and warranties

We provide the service as available. Maintenance, security work, network problems and provider outages can interrupt it. We do not promise uninterrupted operation, a particular confirmation time or that every error will be prevented. Keep your own transaction records and a way to contact customers during an outage.

To the extent the law allows, we make no implied promise that the service will meet every business need or be free from errors. This does not exclude an express obligation in these terms or any warranty or duty that the law does not allow us to exclude.

14.Limits on our liability

In particular, we are not responsible for losses caused by:

• Crypto sent to a wrong, mistyped or unsupported address, network, token or token version, by you or your customers, and payments that are short, too large or late.
• You, your team or your systems: lost or leaked passwords, two-factor codes, recovery codes, API keys or webhook secrets, compromised devices or email accounts, and anything done with your credentials.
• Blockchains and third parties: forks, reorganisations, congestion, fee spikes, outages, bugs or attacks affecting networks, smart contracts, bridges, token issuers (including freezes and loss of peg), wallets, exchanges and the infrastructure and data providers we rely on.
• Price movements between a quote, a payment, a credit and a payout.
• Delays, holds, declines, suspensions, reviews or refused transfers made for security, screening, legal or compliance reasons, or because the law or an authority requires them.
• Events beyond our reasonable control, including attacks on our systems despite reasonable security measures, war, unrest, natural disasters, power or internet failures and government action.
• Disputes between you and your customers, and anything you sell or promise them.

We have no duty to recover funds sent in error. If we choose to try, recovery is never guaranteed and we may charge the costs to you.

Neither party is liable for indirect or consequential losses, including lost profits, revenue, business, goodwill, data or anticipated savings. In every case, our total liability to you for all claims arising from the service is limited to the processing fees you paid us in the 12 months before the event that gave rise to the claim. Related claims share that limit.

Tell us about a disputed transaction within 30 days of it appearing in your dashboard, and bring any claim within one year of when you knew or should have known about it. After that, the claim is waived to the extent the law allows.

These limits do not reduce our obligation to pay out balances lawfully due to you, and they do not apply to our fraud or wilful misconduct or to any liability the law does not allow us to exclude or limit.

15.Claims caused by your business

As a merchant, you must cover reasonable losses, damages and legal costs from third-party claims caused by your unlawful goods or services, infringement of another person's rights, or material breach of these terms. This obligation applies only to the extent the claim is your responsibility. It does not cover losses caused by our own breach, negligence or misconduct.

We will notify you promptly of a claim, allow you a reasonable opportunity to participate in its defence and take reasonable steps to limit costs. Neither party may agree a settlement that admits fault or imposes obligations on the other without that party's consent.

16.Changes to these terms

We may update these terms as the service or legal requirements change. We will publish the new version and give at least 30 days notice by email or in your dashboard for material changes. Changes needed to meet a legal requirement or address an urgent security risk may take effect sooner; we will explain when we can.

Changes apply from the stated effective date, not retroactively to a dispute that has already arisen. If you do not agree, stop using the service and request closure before that date. Continued use after a properly notified change takes effect means you accept it, to the extent permitted by law.

17.Governing law, disputes and contact

These terms, and any dispute between you and us arising out of or in connection with them or your use of the service, including non-contractual disputes, are governed by the laws of the Hong Kong Special Administrative Region. Disputes between a merchant and its customers are between them and are not covered by this section.

Before starting proceedings, send the other side a written notice describing the dispute: to us at [email protected], to you at your account email, the email you gave at checkout or other contact details we have. Both sides will then try in good faith to resolve it for 30 days after the notice is received, after which either side may start proceedings. Either side may start them sooner to stop a time limit expiring, and if we have no way to contact you, the 30 days do not apply. The reporting and claim periods in the liability section above are paused during those 30 days.

Except as the next paragraph provides for consumers, disputes will be decided only by the courts of the Hong Kong Special Administrative Region, and both sides submit to their jurisdiction. Proceedings in those courts will be conducted in English, subject to the court's directions. Subject to the next paragraph, either side may at any time, including before giving notice or during the 30 days, ask any court with jurisdiction for urgent interim or protective relief, for example to freeze funds or protect confidential information, but not to decide the dispute itself.

If you use the service as a consumer, meaning for purposes outside your trade, business or profession, the choice of law, courts and language above is subject to the mandatory protections of the law of the country where you live. You may bring a claim in your local courts where that law allows. We will bring a claim against you in the courts of that country where that law requires it, and otherwise in the courts above. No dispute goes to arbitration unless both sides agree in writing after it arises, and nothing here waives a right to bring a claim where mandatory law permits it.

For questions about these terms or a request to review a restriction, write to [email protected]. To make a complaint, follow the Complaints Procedure at /complaints; it explains how we acknowledge, investigate and escalate complaints and where to seek outside help. For account or payment help, use [email protected]. You can also write to ZeroFive, Hong Kong (full address to follow).
