WrapPay — Multi-Chain Crypto Payment Gateway

WrapPay is a decentralized payment gateway that enables businesses to accept cryptocurrency payments across multiple blockchain networks while receiving settlements in their preferred token (e.g., stablecoins).

Think of it as a “Stripe for Web3” — simplifying crypto payments into a seamless, single integration.

✨Key Features

• 🌐 Multi-Chain Support Accept payments on Ethereum, Solana, and other EVM-compatible chains.

• 👛 Multi-Wallet Integration Supports wallets like MetaMask, Phantom, WalletConnect, Solflare, and Coinbase Wallet.

• 🔄 Token Flexibility Customers can pay in any supported token while merchants receive a predefined token (e.g., USDC).

• ⚙️ Smart Contract Fee Splitting Automated on-chain deduction of platform fees (e.g., 0.75%).

• ⚡ Seamless Checkout Experience Unified UI for handling different chains and wallets.

• 🔐 Decentralized & Trustless Payments are executed via smart contracts — no centralized custody.

🧱 Architecture

WrapPay follows a modular Web3 architecture:

• Frontend: React + Web3 libraries (Wagmi, Solana Wallet Adapter)

• Blockchain Layer:

  • Ethereum / EVM smart contracts (Solidity)
  • Solana program support

• Wallet Layer:

  • MetaMask, Phantom, WalletConnect, etc.

• Payment Flow:

  1. User selects token & wallet
  2. (Optional) Token swap
  3. Smart contract handles transfer + fee split
  4. Merchant receives funds

🔄 Payment Flow

User → Select Token → Connect Wallet → Swap (if needed) → Execute Transaction → Smart Contract Splits Fee → Merchant Receives Payment

🛠️ Tech Stack

• Frontend: React, TypeScript
• Web3 (EVM): Wagmi, Ethers.js
• Web3 (Solana): @solana/web3.js, Wallet Adapter
• Smart Contracts: Solidity
• Blockchain Networks: Ethereum, Solana, Polygon (extendable)
