A drop-in WooCommerce payment gateway that lets merchants accept crypto across Ethereum, Polygon, Solana, and BNB Chain, with auto FX conversion, branded checkout, and webhook-driven order updates.

The problem

WooCommerce merchants want to accept crypto, but integrating wallets, multi-chain support, FX conversion, and reconciliation is painful. Traditional rails also hit them with chargebacks, roughly 3% card fees, and geographic limits.

How it works

The merchant signs up on the Copperx dashboard, sets a withdrawal address and brand logo, generates an API key, and pastes it into WooCommerce under Settings → Payments → Copperx.

At checkout, the buyer is redirected to a Copperx-hosted checkout session. Order status updates flow back via webhook (since v1.3.0) for near-instant confirmation. API polling is the fallback.

Optional toggles cover test mode, debug logs, and which billing or shipping fields to collect.
