How sponsorship works
Sponsoring is an optional way to fund the build directly. It's not a subscription replacement — it's an extra channel for people who want to back the project beyond their own Pro fee. Each cumulative $100 of contribution gives you +30 days of Pro on top of what you already have.
What sponsorship is — and is not
Sponsorship is a one-time crypto payment in USDT (TRC20 or ERC20). There is no automatic monthly debit — we don't hold your wallet keys and we don't issue invoices on a schedule. To contribute again you create a new sponsorship invoice from the /sponsors page whenever you choose. This intentional friction keeps us a non-custodial, no-billing-agreement business.
The flow
- Open /sponsors and pick an amount ($50 / $100 / $250 / $500 or a custom amount, $50–$10000). Pick the network you'll send from (TRC20 recommended for low fees).
- Optionally set a display name and a short public note. Decide whether you want to appear on the public sponsors list when the payment confirms — this is opt-in.
- Press "Create invoice". You land on the same /app/billing/invoice/[id] page used for subscription invoices. Copy the exact amount (sub-cent precision for matching) and the wallet address, send the transfer.
- Once the on-chain transaction is detected (auto-confirm watcher polls every 30s, or admin confirms manually), the Sponsorship row is marked Paid, any earned Pro months are added to your subscription, and you get a thank-you email.
How Pro months are earned
We track cumulative confirmed sponsorship per user. Every full $100 crossed unlocks one +30-day Pro extension. The math is:
- $50 contribution → cumulative $50 → no Pro yet (below the $100 threshold).
- Second $50 contribution → cumulative $100 → +30 days of Pro added.
- $150 contribution from cumulative $0 → crosses the $100 threshold once → +30 days of Pro. The remaining $50 sits in the running total toward the next $100.
- $200 contribution from cumulative $0 → crosses both $100 and $200 → +60 days of Pro added in a single payment.
Accrual is computed per Sponsorship row at the moment its invoice confirms, so re-confirming or replaying an invoice does not double-grant. If you have an active Pro subscription, the days are appended; if you don't, a fresh Pro subscription is created starting today.
Public sponsors list
On /sponsors there's a "Recent sponsors" section listing confirmed sponsors who opted in to publicity. Entries show the display name (or "Anonymous" if blank), the contribution amount, the date, and the optional public note. We never publish your wallet address or your account email. You can stay completely anonymous by unchecking the public-display toggle when you create the invoice.
What about recurring sponsorship?
There is no on-chain auto-debit. To support the project monthly you create a new sponsorship invoice each month — the same five-minute flow. The marketing copy on /sponsors mentions "recurring sponsorship (≥ $50/month)" as a behavioural pattern, not as an automated billing arrangement: as long as your cumulative contributions cross $100 every two months, your Pro subscription stays funded with no out-of-pocket subscription fee. Set a calendar reminder if you want to keep it consistent.
Sponsorship vs subscription
Subscription invoices (/app/billing) are fixed-price Basic $17 / Pro $35 with a 30-day extension on confirmation. Sponsorship invoices (/sponsors) are user-amount and grant Pro time only when the cumulative crosses a $100 boundary. The two systems share the same crypto invoice pipeline under the hood, but they are independent — you can hold an active Pro subscription and sponsor on top, or sponsor without ever having paid for Pro.
Refunds, disputes, custom formats
Sponsorship is a voluntary contribution rather than a service purchase, so there is no fixed-window refund policy (unlike subscription invoices). If a sponsorship payment is sent in error or the funds need to be returned, email support@crypt-hunter.com with your invoice ID and the transaction hash — we'll work it out case by case. Same address if you want to set up a non-standard format (recurring auto-debit through a third-party processor, larger contributions paid through a wire, etc.).
