NormiePay Crypto Checkout

NormiePay is a non-custodial crypto payment gateway. This plugin lets your WooCommerce store accept USDC on Base and Polygon. Each order redirects to a hosted NormiePay checkout; when the payment confirms on-chain, a signed webhook marks the order paid automatically.

• Non-custodial — funds settle on-chain directly to your wallet via smart contract
• USDC on Base & Polygon (the customer picks at checkout)
• One-click webhook setup — just paste your API key and save
• Signed (HMAC-SHA256) webhooks verify every payment
• Automatic on-chain refunds for over/underpayment

1. Upload the plugin zip via Plugins → Add New → Upload Plugin, then Activate.
2. Go to WooCommerce → Settings → Payments → NormiePay.
3. Paste your NormiePay API key (Dashboard → API Keys) and click Save changes. Your webhook is registered automatically.
4. Enable the gateway. Done.

Requires a NormiePay account (https://normiepay.xyz) with a payout wallet and company name set.
