About this plugin
KXCO Pay lets your store accept cryptocurrency payments that go straight to your own wallet. There is no middleman, no account to open, and KXCO Pay never touches your funds — it simply watches the blockchain and confirms when a payment arrives.
Why KXCO Pay
- Non-custodial. Customers pay your address directly. You keep 100% of every payment.
- Zero commission. No per-transaction fee from us, ever.
- Bitcoin, Ethereum, USDT (ERC-20) and USDC (ERC-20) out of the box.
- WooCommerce gateway — appears at checkout, settles the order automatically on confirmation.
- Shortcode & block — drop a “Pay with Crypto” button on any page for donations, invoices or simple sales, outside the WooCommerce checkout flow.
- Live checkout widget — QR code, one-tap copy, locked-rate countdown, and real-time status as the payment confirms.
- Fiat pricing. Price in USD/EUR/GBP; KXCO Pay converts to crypto at the live CoinGecko rate and locks it for the checkout window.
How it works
- Enter your receiving wallet addresses in KXCO Pay → Settings.
- A customer chooses a coin at checkout and is shown an exact amount + address + QR code.
- KXCO Pay watches the chain (mempool.space / Blockstream for BTC, a public explorer for ETH & tokens) and marks the order paid once it reaches your required confirmations.
Requirements
WooCommerce must be installed and active. The PHP bcmath extension is recommended for exact crypto amounts; KXCO Pay degrades gracefully without it.
KXCO Pay is an independent plugin from KXCO. It is not affiliated with, endorsed by, or sponsored by Automattic Inc. or the WooCommerce project — see the Trademarks section below.
KXCO also sells a separate commercial add-on called KXCO Pay Pro. It is an independent product and is not required — every feature described above is included here and fully functional on its own. io.
External services
To verify payments on the blockchain and price orders in your currency, KXCO Pay
contacts the following third-party services. No personal data is sent — only public
blockchain addresses and coin/currency codes required to confirm a payment.
- CoinGecko API ( api.coingecko.com ) — fetches live exchange rates to convert your
fiat prices to crypto. Sends: coin id + currency code. com/en/privacy
- mempool.space ( mempool.space ) or Blockstream ( blockstream.info ) — reads the
Bitcoin blockchain to detect and confirm BTC payments. Sends: the receiving BTC address.
info
- Etherscan ( api.etherscan.io, only if you enter an API key) or Blockscout
com, keyless default) — reads the Ethereum blockchain to confirm ETH,
USDT and USDC payments. Sends: the receiving Ethereum address. Terms:
com
These calls happen only when a payment is in progress (or on a short background check).
You can change the Bitcoin and Ethereum data sources in the plugin settings.
