Hey Product Hunt 👋 I'm Paul, the founder of QBitFlow. Quick story on why this exists, because it's the whole point. I've been building in web3 for a while, and one thing kept bugging me. Every time I hit a subscription-based service, the "billing" was the same: "send X every month," or "send me P×X up front and trust that I'll keep delivering for the next P months." That's it. Prepay and hope. The opposite of what crypto was supposed to be. After running into it enough times, I just… stopped wanting to pay that way. Why would I send months of money in advance to a service I'm not even sure will still be there next week? So I went looking for a way to do subscriptions the way cards do them — charge me each period, only while I'm getting the service — but on crypto. I found nothing that did it properly. Everything was prepay-and-trust. And here's the thing: cards aren't actually better. When you subscribe with a card, you hand a company the keys to your account and trust they'll only take what's fair. With all the breaches and sketchy checkouts out there — you've definitely landed on a site and hesitated before typing your card in, I know I have — is that trust really earned? That's the problem QBitFlow solves. Turns out there was no good solution because it's a genuinely hard problem — but we cracked it. You approve a subscription once, and the amount, the schedule, everything is enforced on-chain. The merchant literally cannot pull more than you agreed to. No prepaying. No handing over the keys to your account. No "trust us." Blockchain was built for this — real ownership and security — before all the tokens and memecoin noise buried that under hype. QBitFlow is us going back to those fundamentals for the most basic thing of all: getting paid. So here's what it actually is: Why crypto at all, and not just a card? Because anyone, anywhere can pay you — no processor gating your customers out by country — the money's in your wallet in seconds instead of a week, and once it's there it's yours. No one can hold it, delay it, or claw it back. Why QBitFlow, over everyone else? Because the money is never ours. It goes straight from your customer's wallet to yours, on-chain, and you hold the keys the whole time. There's no QBitFlow balance to withdraw from, no payout delay, no approval to wait on — because we never touched your money. Every payment is on-chain and verifiable; we're not an obscure processor you have to take on faith. What you get: • Live in minutes — connect a wallet, create a product, get paid. No KYC, no company paperwork. • Real on-chain subscriptions (the thing that started all this), one-time payments, and marketplaces with automatic fee splits. • 1.5% flat. No withdrawal fees, no conversion fees, no chargebacks. You receive the exact token your customer paid — no surprise swaps. • ETH, Base & Solana. Hosted no-code checkout, or JS/TS, Python & Go SDKs + REST if you build. • Accountant-ready CSV export built in — USD value at time of receipt, every fee broken out. (The crypto-accounting headache, solved.) • Open-source, auditable contracts — read or fork every line on GitHub. (Not formally third-party audited yet — that's on the roadmap. I'd rather say so than claim a badge we haven't earned.) My whole goal was to make it barely harder than using a card — just a lot more secure. It's the same idea as Stripe, but your money never stops being yours. I'm here all day. Ask me anything, tear it apart, tell me what's missing. If you're building something and "getting paid" is in your way, I'll help you set it up personally. 👉 qbitflow.app · docs at qbitflow.app/docs 🎁 P.S. — launch bonus: sign up before July 18 (the launch-week window) and your referral link locks in 40% of our fee — double our usual 20% — for life.
