Cryptoniq vs Unuspay Crypto Payments for WooCommerce

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. 1. api.coingecko.com — exchange rates What it is: CoinGecko’s free public price API. What it’s used for: Converting your store’s order totals from fiat (USD, EUR, GBP, …) into the equivalent amount of BTC or ETH the customer needs to send at checkout. What data is sent: Only the public coin identifiers (bitcoin, ethereum) and the target currencies (usd, eur) the plugin needs prices for. The request URL looks like https://api.coingecko.com/api/v3/simple/price?ids=bitcoin,ethereum&vs_currencies=usd,eur. No personal data, no order data, no site identifiers. When it’s sent: Once every 30 minutes via WordPress cron (background), and on plugin activation if no cached prices exist yet. Never on a customer-facing page load. Terms of Service: https://www.coingecko.com/en/terms Privacy Policy: https://www.coingecko.com/en/privacy 2. blockchain.info — BTC transaction lookups What it is: Blockchain.com’s public Bitcoin blockchain explorer. What it’s used for: Checking whether the customer’s expected BTC payment has arrived at the wallet address you configured. The plugin asks blockchain.info for the list of unspent outputs at that address and looks for one matching the order’s expected amount. What data is sent: Only the merchant’s BTC wallet address — the same address the buyer is asked to send funds to (already public, both on your checkout page and on-chain). The request URL looks like https://blockchain.info/unspent?active=YOUR_BTC_ADDRESS. No buyer data, no order ID, no site identifiers. When it’s sent: Only while a customer is actively on the Cryptoniq payment page for an unpaid BTC order — polled via AJAX every few seconds until payment is detected or the 3-hour payment window expires. Never otherwise. Terms of Service: https://www.blockchain.com/legal/terms Privacy Policy: https://www.blockchain.com/legal/privacy 3. api.etherscan.io — ETH transaction lookups What it is: Etherscan’s public Ethereum blockchain explorer API. What it’s used for: Same purpose as blockchain.info but for ETH — checking whether the customer’s expected ETH payment has arrived at the merchant’s wallet address. What data is sent: Only the merchant’s ETH wallet address and an Etherscan API key (the plugin ships with a free shared-tier key; you can replace it via the apikey_eth option). The request URL looks like https://api.etherscan.io/api?module=account&action=txlist&address=YOUR_ETH_ADDRESS&apikey=.... No buyer data, no order ID, no site identifiers. When it’s sent: Only while a customer is actively on the Cryptoniq payment page for an unpaid ETH order — same AJAX polling schedule as blockchain.info above. Never otherwise. Terms of Service: https://etherscan.io/terms Privacy Policy: https://etherscan.io/privacypolicy The plugin never connects to api.cryptoniq.io or any other server controlled by the plugin author — all blockchain and price data comes from the three independent public services listed above. Third-Party Libraries This plugin ships with the following third-party JavaScript libraries. The minified files in assets/js/cryptoniq.libs.js are publicly maintained open-source projects — full unminified source is available at each project’s repository: clipboard.js v1.7.1 — copy-to-clipboard helper for the payment box.
