Project description:
"Project Overview:

We are building a global crypto payment gateway running on the Solana blockchain.

The platform will allow both individuals and businesses to accept crypto payments easily.
It will function similarly to platforms like NOWPayments, Coinbase Commerce, and Helio, with a focus on Solana’s fast and low-fee infrastructure.

What We’re Looking For:

We’re seeking an experienced blockchain developer (or a small team) who can help us build a working MVP for a crypto payment gateway. You should have:

Strong experience with the Solana ecosystem
Familiarity with SPL Tokens, especially USDC-SPL and SOL
Knowledge of Solana Pay, Phantom Wallet, and Wallet Adapter SDK
Backend experience (Node.js / Python / Rust preferred)
Ability to track on-chain transactions and trigger webhooks
REST API development skills
(Bonus) Smart contract development using Anchor Framework

Key Features to Develop (MVP):
• Wallet-based user login (Phantom or Solflare)
• Create crypto payment links & QR codes
• Accept payments in USDC (SPL) and SOL
• On-chain payment detection (listener service)
• Trigger webhook to notify merchants of completed payment
• Simple user dashboard (transaction history, API key management)
• REST API for payment creation, status check
• Integration with Solana devnet for testing

Project Scope:
• This is an MVP build for validation purposes
• Future collaboration is possible for full-scale product development
• UX/UI designs are mostly ready
• Functionality is the top priority in this phase
• Fully remote, async-friendly
