I run a Shopify-based e-commerce store and I’m ready to start accepting Tether (USDT) at checkout. I need a developer who can build and install a fully functional USDT payment gateway that plugs seamlessly into my existing Shopify setup, routes the customer to a blockchain payment page, detects on-chain confirmation, then updates the order status inside Shopify in real time. The solution must • sit alongside my current card and PayPal options without disrupting them, • generate a unique wallet address or payment reference per order, • listen for the confirmation callback and mark the order as Paid automatically, • display clear success/failure messages to the shopper. I’m open to whichever network (ERC-20, TRC-20, etc.) you feel is most reliable, provided the fees stay low and confirmation times are reasonable. If a third-party API or custodial service is required, please outline the pros, cons, and ongoing costs so I can make an informed decision. Deliverables 1. A private, installable Shopify payment app or custom gateway code. 2. Written setup instructions plus any API keys or webhook URLs I’ll need. 3. A short test script or demo order proving funds flow and status update. 4. Post-deployment support for initial bug fixes. If you have previous Shopify gateway or blockchain work, links or screenshots will help me select quickly.

I can deliver a Shopify USDT payment gateway that sits beside card/PayPal, redirects customers to a secure crypto payment page, watches the blockchain for confirmation, and auto-marks the Shopify order as Paid via webhooks/admin API. Approach (proven + low friction) Build a private Shopify payment app (Node.js/TypeScript) + hosted checkout page. On order creation: generate a unique payment reference (preferred) or unique address per order (HD wallet derivation) and lock the USDT amount + expiry. Use a reliable chain monitor (RPC + indexer) to detect incoming USDT, wait N confirmations, then update Shopify order financial_status=paid and add transaction metadata. Clear UX: pending/confirmed/expired/failed screens + email receipt. Network recommendation TRC-20: low fees + fast confirmations (best for customer UX). ERC-20: more universal but higher fees. We can support both if needed. Custodial vs non-custodial Non-custodial (your wallet): safest control, needs proper key management + monitoring infra. 3rd-party (Coinbase Commerce/BitPay/etc.): faster setup, ongoing fees, less control. I’ll present pros/cons and costs before we lock it in. Deliverables Installable Shopify app + gateway logic Setup docs (API keys, webhook URLs, env vars) Demo order + test payment showing real-time status update Post-deploy bug-fix support I’ve integrated crypto payments + webhook-driven order settlement and can share similar builds on request.

Hello, I’m Muhammad Awais. I will build and install a private Shopify payment gateway that runs alongside your existing card and PayPal options, so your checkout flow remains unchanged. I’ll create a USDT gateway that generates a per‑order wallet address or reference, redirects customers to a clean on‑chain payment page, detects confirmations in real time, and auto‑updates the Shopify order as Paid. The design will support ERC‑20, TRC‑20, or other networks you prefer, balancing low fees with fast confirmations. If a third‑party API or custodial service is used, I’ll lay out the pros, cons, and ongoing costs so you can choose confidently. Deliverables include a private installable app or code, setup docs and API keys/webhook URLs, a short test script proving funds flow and status update, and post‑deployment bug fixes. You’ll get clear success/failure messages for customers and the existing checkout will stay intact. Which USDT networks would you like supported (ERC-20, TRC-20, or others), and what are your preferred fees/confirmation times? Do you want a non-custodial per-order wallet or rely on a third-party custodial service, and what level of security and control do you require? Should the gateway be implemented as a private Shopify app or custom gateway code, and do you need multi-currency support beyond USDT? What API keys, webhook URLs, and Shopify store access can you provide for development and testing? How should refunds, failed confirmations, or disputes be handl

Hi, This is a payment flow problem first, and a blockchain choice second. The system needs to behave like a normal Shopify gateway from the store’s point of view. That means each order generates a unique payment reference, the customer is routed to a clear payment page, confirmations are detected reliably, and the order state updates automatically without manual intervention. This works best as a small, focused payment app sitting next to your existing gateways. I d structure it as a simple pipeline -> Shopify creates the order, the gateway issues a unique USDT address or memo, a listener watches the chain for confirmation, and a webhook updates the order to Paid once the transaction is final. Network choice (ERC-20, TRC-20, etc.) is decided based on fee, speed, and operational reliability, and I ll clearly outline the tradeoffs before locking it in. The checkout experience stays clean with clear success and failure states so customers aren’t guessing. The focus is a gateway that feels native to Shopify, settles deterministically, and is easy to maintain after handoff. If this direction aligns, we can discuss in detail in chat.
