About this plugin
CoinPayGateway is a no KYC, non-custodial crypto payment gateway for WooCommerce. It adds a cryptocurrency payment method to your checkout, and payments travel directly from your customer’s wallet to a wallet you control. The plugin only ever handles public keys and receiving addresses, which can never spend funds.
Use it as a Bitcoin payment gateway, a USDT or USDC stablecoin payment gateway, or a full multi coin crypto checkout. It is a no KYC, non-custodial way to accept cryptocurrency payments on any WooCommerce store, with no signup, no application, no middleman, and 0% transaction fees. Stablecoins can be accepted on both Ethereum (ERC-20) and Tron (TRC-20), and the gateway works in both the block checkout and the classic checkout.
Whether you want to accept Bitcoin, accept USDT, accept crypto donations, or run a high risk store that card processors will not serve, payments settle straight to your own wallet.
Supported coins
- Bitcoin (BTC), with HD wallet support: paste a zpub and every order gets its own unique receiving address
- Litecoin (LTC), with the same HD wallet support
- Ethereum (ETH)
- Tether (USDT) and USD Coin (USDC) as ERC-20 tokens
- Solana (SOL)
- XRP, with an automatic Destination Tag per order
How it works
- The customer picks a coin at checkout and gets the exact amount at the live exchange rate in your store currency, a payment address, and a QR code.
- The plugin watches the blockchain. The payment page updates itself every 15 seconds, and a background check keeps watching even after the customer leaves the page.
- When the payment confirms on-chain, the WooCommerce order is completed automatically. One blockchain transaction can only ever confirm one order.
Merchant features
- Unique payment amounts per order so payments always match the right order
- Configurable matching tolerance (plus or minus 1, 2, 3 or 5 percent)
- Choice per coin between HD wallet mode (unique address per order) and single address mode
- Sum-matching for split payments, with automatic underpayment emails
- Customer TXID submission with precise diagnostics (found, awaiting confirmation, wrong amount, wrong Destination Tag)
- Automatic cancellation of unpaid orders after 24 hours, with a one-click restore link for the customer
- Manual confirm action on the order screen for edge cases
The plugin is free. Payment verification runs on the CoinPayGateway service (see Third-party services), which watches the blockchain for you, so there are no API keys to configure. com) removes the limit.
