ChainPay Gateway is a self-hosted, multi-chain crypto payment gateway built for merchants who want to accept Bitcoin, Ethereum, USDT, BNB, Solana, Litecoin, Dogecoin and more without relying on a third-party processor.

One Laravel install, one MySQL database, one ZIP. Drop it on any host that runs PHP 8.3+, walk through the install wizard, and you're ready to take crypto payments via an embeddable widget, a hosted checkout page, or a REST API.

Why ChainPay?

• Self-hosted. Your server, your wallets, your keys. No platform fees, no rate limits beyond your RPC, no middleman touching your customers' money.
• 17+ chains supported. BTC, ETH, BNB, USDT (ERC-20 / BEP-20 / TRC-20), USDC, LINK, SHIB, BAT, BUSD, LTC, DOGE, BCH, XRP, SOL, ALGO, XMR, plus any ERC-20 / BEP-20 / TRC-20 token via the admin custom-token panel.
• Auto-confirms on chain. Built-in cron polls the blockchain every minute via Alchemy, BscScan, mempool.space, TronGrid, XRPL, Solana RPC and Algorand Indexer — payments confirm without you lifting a finger.
• Fiat fallback. Stripe + PayPal sit alongside crypto in the same picker. Customers choose at checkout.
• One-line widget embed. A single <script> tag and a <div> with a checkout slug — popup or inline — and you're live on any website (WordPress, Shopify, custom HTML, anything).
• Polished admin panel. Inertia + Vue 3 + Tailwind v4 dashboard with charts, activity feed, install-health monitoring, branded settings, security controls, role-based access, and a "Login as user" support flow.

Live demo

Try the full product before you buy:

• Demo URL: chainpay.codic.online
• Admin login: [email protected] / password: password
• Documentation: chainpay.codic.online/docs

The demo runs in safe-preview mode — you can browse every screen, complete a real test transaction, and read the docs, but admin save actions are disabled with a toast prompting purchase.

Quick start (5 minutes)

1. Unzip the package onto your server. Point your domain's document root at the public/ directory inside the unzipped folder.
2. Visit your domain in a browser. The install wizard auto-launches because .env is missing.
3. Step through the wizard:
   • Database — host, name, user, password (the wizard tests the connection live)
   • Owner account — name, email, password
   • Branding — product name, tagline, primary colour
4. Set up cron in your hosting panel — every minute, run php artisan schedule:run. (Detailed Hostinger / cPanel / VPS instructions live at /docs/ after install.)
5. Add wallet addresses in Admin → Wallets for each crypto you want to accept.
6. Get a free Alchemy API key at alchemy.com and paste it into Admin → Settings → Blockchains (one key powers ETH, BSC, Solana, all ERC-20s, all BEP-20s).
7. Embed the widget on your site:

   <code><script src="https://your-domain.com/widget.js" defer></script>
   <div data-cpg-checkout="your-slug" data-cpg-layout="inline"></div></code>
