QBitFlow

Non-custodial crypto payments and subscriptions

Development & IT

About the startup

I'm Paul, the founder of QBitFlow. We are building a SaaS dApp that enables merchants to receive one-time and recurring payments without giving up custody of their funds. The Problem with Existing Solutions: Most crypto payment tools rely on escrow-like models or pre-funding. Users have to move funds into a third-party contract and trust that provider to disburse them. The QBitFlow Approach: We rely on an authorized spending cap. The user signs for a specific limit, and our smart contracts then enforce exactly how those funds are pulled (frequency and amount). This ensures funds cannot be used in any way other than what the user originally authorized. --- Key Features --- For Merchants: - Dead Simple Integration: 5 lines of code to create a payment page and start receiving payments. Our platform/SDK handles the rest. - USD Pricing: Set your prices in USD. QBitFlow automatically converts to the user's selected cryptocurrency in real-time. - Multi-Chain, One Wallet: Connect your Solana wallet → instantly accept SOL and all supported tokens. Same for Ethereum. You can disable specific tokens if needed. - Subscription Autopilot: QBitFlow handles payment retries, subscription status, cancellations, and all on-chain enforcement. You just fetch the subscription status via the SDK and update your app logic accordingly. - Test Mode: Try the entire payment flow for free on test networks (Sepolia, Solana Devnet). Get free test tokens from faucets, create products, run transactions—zero risk, zero cost. Perfect for integration testing before going live. For Payers (Your Customers): - No Account Needed: Users simply connect their Web3 wallet and pay. No sign-ups, no emails. - Gasless Token Payments: QBitFlow pays the network fees in the native currency (ETH, SOL) and gets reimbursed in the token the user paid with. Users don't need to hold native currency or worry about gas — QBitFlow handles it automatically. - Full Control: After payment, users access their payment details. For subscriptions, they manage everything on-chain (via our web app): increase allowance/spending cap, cancel, or renew — all enforced by smart contracts. ------------------------ Non-Custodial & Transparent: - QBitFlow never holds your funds. - All contracts and SDKs are publicly available on GitHub for audit and integration. - Multi-Chain: Currently supports Ethereum and Solana, along with several of their tokens. Our Slogan: Security, Simplicity, and Transparency. Why We're Here: QBitFlow is in the early stages, and I am looking for beta testers—specifically merchants, SaaS founders, or developers looking to integrate crypto subscriptions or one-time payments. I'd love your feedback on: - The onboarding and integration experience - The non-custodial spending cap model - The gasless payment UX for end users - Test mode and how easy it is to get started If you have a use case for recurring crypto payments, one-time checkouts, or pay-as-you-go models, let's talk! Ready to test? Switch to Test Mode in the dashboard, grab free test tokens from a faucet, and run your first transaction in minutes—no real money, no risk. GitHub: https://github.com/QBitFlow
