Cryptoniq

Cryptoniq is a free, decentralized cryptocurrency payment gateway for WooCommerce. Buyers pay you directly in Bitcoin (BTC) or Ethereum (ETH) — the funds land in your wallet, not on a third-party platform that holds them, takes a cut, and makes you withdraw.

No accounts. No KYC. No custodian. Just paste your wallet address and start accepting crypto.

Why Cryptoniq?

Most “crypto gateways” are actually middlemen: you sign up on their platform, they hold your funds, charge a percentage, and you wait to withdraw. Cryptoniq flips that. Payments go peer-to-peer, on-chain, straight from the buyer’s wallet to yours.

• You keep 100% of your sales — zero platform fees on top of network gas.
• No registration required — install, paste your wallet, done.
• Direct on-chain payments — funds arrive in your wallet within minutes.
• Real-time price conversion — order totals are quoted in your store currency and converted to crypto at the live rate.

Features

• WooCommerce checkout integration — adds Cryptoniq as a payment method like any other gateway.
• Clean, mobile-friendly payment box with a QR code and one-click address copy.
• Automatic order confirmation when the on-chain transaction is detected.
• Live BTC and ETH exchange rates for EUR and USD (this free version supports those two store currencies — see PRO for 150+ currencies).
• Multiple wallet addresses per coin — Cryptoniq rotates through them per order.
• HPOS (High-Performance Order Storage) compatible.

Supported coins

• Bitcoin (BTC)
• Ethereum (ETH)

Want more coins, stablecoins, or instant detection?

A separate paid plugin, Cryptoniq PRO, is sold at cryptoniq.io. It is not included in or downloaded by this free plugin — it’s a separate plugin you install alongside this one. PRO adds:

• Litecoin, Dogecoin, TRON, Solana, BNB Smart Chain
• ETH on Arbitrum One and Optimism
• USDT and USDC stablecoins on multiple chains
• Real-time webhook detection (no waiting on polling)
• 150+ fiat currencies for conversion
• Priority support

This free version does not contain any PRO code or features — it’s fully functional standalone, and there is no license key field anywhere in this plugin.

External services

This plugin relies on three external services to do its job. They are all free, public, and require no account or API key (the bundled Etherscan key is a shared default that you can override). No personal data is ever sent — not the buyer’s name, IP, email, order details, or anything else. Only public blockchain addresses you have already chosen to share, and the public identifiers of the coins/currencies whose prices the plugin needs to quote.
