Build Crypto 2D Website Gateway

@rahuliitm69

Hi, I’ve read your requirements and understand the complete fiat-to-BTC one-time payment flow you need. I’ll build a secure REST-based backend with card tokenisation via a PCI-DSS-compliant payment processor, keeping sensitive card data outside your system. After successful payment capture, the backend will trigger the exchange API, calculate the BTC equivalent, and send it directly to your configured Bitcoin wallet. I’ll implement blockchain verification + webhooks to confirm the BTC transaction and automatically update the order status. A lightweight JavaScript/HTML checkout snippet will connect with the backend and handle success, pending, failure, refund, and chargeback states. I’ll also provide configurable environment settings, admin/API logs, Postman tests, commented code, and a Linux VPS deployment guide. Preferred stack: Node.js/NestJS + PostgreSQL + REST APIs, with sandbox testing first and a controlled transition to production/live keys. Best, Rahul

Hello, Your project for a 2-D International payment gateway with automatic BTC conversion/settlement aligns perfectly with my expertise in PHP, JavaScript, Website Design, HTML, and Payment Gateway Integration. With over a decade of experience in web development, I have successfully integrated similar payment gateways for clients in the past. I propose to develop a secure back-end service for card tokenization, payment processing, and BTC settlement, along with a concise JavaScript snippet for seamless front-end integration. Leveraging RESTful APIs and my API development skills, I will ensure PCI-DSS compliance and real-time transaction verification on-chain. I recommend implementing a robust admin panel for easy management and monitoring. I assure you of a fast and reliable delivery, focusing on clear documentation and support throughout the process. Let's discuss your project requirements further to ensure a successful collaboration. Looking forward to hearing from you. Best regards,

@SmartCodeDev

Hello, I can build this as a clean PHP or Node.js service with REST APIs and a lightweight JavaScript checkout snippet. Card data will stay with a PCI-compliant hosted-fields provider, so your server handles tokens, not raw card details. The payment flow will create a one-time fiat charge, confirm it by signed webhook, request BTC conversion through the selected regulated provider, then track the transaction ID and blockchain confirmations before updating the order. I’ll also add idempotency checks so duplicate callbacks never trigger double settlement. You’ll get payment and settlement logs, refund and chargeback routes, configurable wallet and fee settings, pending/success/failure UI states, Postman tests, .env template, and Linux VPS deployment docs. One practical point: refunds and chargebacks cannot simply reverse an on-chain BTC transfer, so I’ll keep fiat payment events and BTC settlement records separate for safe reconciliation. Relevant experience includes payment and trading API work: https://www.freelancer.com/projects/accounting/Mow-Ops-Accounting-Stripe-Integration https://www.freelancer.com/projects/api/Pocket-Quotex-Trading-Bot I can deliver the sandbox-ready build in 14 days, then help switch it to live keys after verification.

@aghazi

Hello, I read your brief on "Build Crypto 2D Website Gateway" and this is squarely what we do. We build API automations and bots in PHP and Python — queueing, retries, error handling and logging, not a script that works once. How I would approach it: 1. Audit the source data and map every field to the target. 2. Migrate a test batch and reconcile it against the original. 3. Run the full migration, then verify totals match. Price: 12500.0 INR fixed, delivered in 1 days. One question so I quote you accurately rather than guess: roughly how many records are involved, and do you need the history migrated or only current balances?

@mayankinnovative

I fully understand your end-to-end architecture for capturing fiat card payments and facilitating automatic Bitcoin (BTC) settlement via an instant exchange API. My Approach: In compliance with PCI-DSS regulations, card data will be securely tokenized on the client side so that sensitive data bypasses your servers. On the backend (Node.js/TypeScript), the creation of a one-time payment intent will trigger a real-time conversion via the exchange API and initiate an on-chain withdrawal to your wallet. A robust webhook listener will be implemented to handle blockchain confirmations and update order statuses. Deliverables will include a drop-in JS snippet for checkout, admin routes for refunds and logging, a Postman collection, and a clear deployment guide for a Linux VPS. 1. Do you have a preferred exchange API (e.g., Kraken, Binance, or Bitfinex) for the fiat-to-crypto conversion? 2. Will the network fee (miner fee) be added to the customer's checkout total or deducted from the merchant's balance? 3. Do you already have a card acquirer or 2-D payment gateway account set up? I am confident in delivering this secure, low-latency, and reliable payment system on schedule. Let’s finalize the technical stack and timeline via chat.

@gurmeetsadik

Hi there, The important part here is making the fiat-to-BTC flow reliable without exposing your system to unnecessary card-data or settlement risks. I can build the gateway around tokenized card payments, server-side payment intents, exchange conversion, and verifiable Bitcoin settlement with webhook-driven order updates. I’d keep card handling within a PCI-compliant payment provider, while your backend manages payment state, conversion requests, wallet configuration, transaction logging, refunds/chargeback states, and on-chain confirmation. The checkout snippet can remain lightweight and communicate only with secured REST endpoints. I can also provide sandbox testing, Postman coverage, environment configuration, deployment documentation, and clear handling for pending, failed, refunded, and successfully settled transactions. Share your preferred payment processor/exchange and Bitcoin network, and I can recommend the backend stack and map the end-to-end flow before development begins. Best, Gurmeet

@amit719

Hi, I can build this payment flow with a secure backend, tokenized card handling, payment intents, fiat-to-BTC conversion, and verifiable on-chain settlement. I’ll keep sensitive card data outside your server by using a PCI-compliant payment processor/tokenization flow, with webhook-driven status updates, idempotency, refund/chargeback handling, and detailed transaction logs. I can provide the checkout integration, REST APIs, BTC settlement verification, sandbox testing, Postman collection, environment configuration, and deployment documentation. I’ll also structure the system for secure Linux VPS deployment and reliable one-time transactions. Thanks Amit

@larencea30

Hi, I’d build this with Node/NestJS + PostgreSQL, using a PCI-compliant payment provider for hosted/tokenized card capture and a regulated exchange/payment API for BTC settlement. Core flow: checkout → tokenized payment → payment confirmation → fiat/BTC conversion → wallet settlement → blockchain/webhook confirmation → order update. I’d implement: • Hosted/tokenized card handling—no raw card data on your server • One-time payment intents • Exchange API abstraction • BTC wallet/network-fee configuration • Signed/idempotent webhooks • Refund/chargeback status routes • Transaction/audit logs • JS checkout snippet • Postman/end-to-end sandbox tests • Docker/VPS deployment docs I won’t claim Bitcoin payment projects I can’t verify; my background includes Stripe, payments, APIs, webhooks, PostgreSQL, security, and production backends. Provider availability, card-to-crypto support, KYC/AML, and jurisdiction rules must be confirmed before live rollout. Timeline: 7–10 days after provider/API access.

@albert1025dev

==== Hi - Albert here ==== **“SECURE ONE-TIME CARD PAYMENTS WITH BITCOIN SETTLEMENT”** — you need a website checkout that accepts fiat card payments and tracks the corresponding BTC settlement with verifiable transaction status. I recommend a compliant payment provider for card tokenization and payment processing, paired with a reputable crypto conversion or settlement API. A PHP or Node.js REST backend can manage payment states, signed webhooks, order updates, transaction logs, and refund or chargeback workflows, while keeping secret keys server-side. I’d build and test the integration in sandbox mode first, including pending, failed, successful, and delayed-settlement scenarios. I don’t have verified prior Bitcoin payment-flow examples to share, so I won’t claim unverified experience. Which countries will you accept card payments from, and do you already have a payment provider and crypto settlement service in mind? Looking forward to work with you

@jaroslavcaprata

Hi, I can build this crypto payment gateway with a secure backend, payment-provider integration, fiat-to-BTC conversion, wallet settlement, webhooks, and checkout integration. I can handle: • Card tokenization and payment intents • Fiat-to-BTC conversion and BTC settlement • On-chain transaction verification • REST APIs and webhooks • Success/failure/pending states • Transaction logs and refund handling • JavaScript/HTML checkout integration • Sandbox testing and Linux VPS deployment I’ll keep sensitive card data outside your system by using a suitable PCI-compliant payment provider and structure the code for secure production deployment. I can target the requested 7-day timeline, subject to the selected payment/exchange providers. Best regards, Jaroslav

@ektatdsl

Hi, The important part of this project is keeping the card-payment flow secure and PCI-compliant while making the fiat → BTC settlement completely traceable, without exposing sensitive payment data in your application. I’ve worked extensively with Node.js APIs, payment integrations, third-party APIs, authentication and secure web applications, and I can structure this as a clean payment service rather than tightly coupling the gateway logic to your website. My approach: → Use a PCI-compliant provider for card tokenisation/payment intents → Keep card data outside your server wherever possible → Process successful one-time payments through the exchange/conversion API → Send BTC to the configured wallet and verify the transaction on-chain → Webhooks to update payment/settlement status reliably → REST endpoints for orders, refunds, logs and chargeback states → Environment-based secrets, sandbox testing, Postman collection and deployment documentation I’d build the architecture so the payment provider or exchange can be changed later without rewriting the checkout. Before starting, which card/payment provider and BTC conversion/exchange API are you already planning to use?
