PiWeb Direct Stablecoin Gateway for WooCommerce

Description

Accept stablecoin payments directly in your wallet — no intermediary, no exchange, no third-party processor needed.

PiWeb Direct Stablecoin Gateway for WooCommerce lets your customers pay with USDC or USDT on popular EVM networks, with funds sent straight to your own wallet address. There are no API keys, no payment processor accounts, and no fees taken by anyone in between.

How it works

1. Customer selects “Pay with stablecoins” at checkout (works with both classic and block-based checkout).
2. They choose a network and token (e.g. USDC on Base), and see the exact amount, your receiving address, and a scannable QR code / EIP-681 payment link.
3. They send the payment from any wallet or exchange.
4. They submit the transaction hash on the order-received page; you get an email notification with a secure link to verify and update the order.
5. Verify the payment on the block explorer and click Change status in the email to update the order — no login required. Link is valid for 2 days.

Key features

• Direct to your wallet — payments go to a single EVM address (0x…) you control. Funds never touch a third party.
• 1:1 fiat pricing — order totals convert 1:1 to the stablecoin amount. No market-price lookups, no volatility surprises.
• Multiple networks & tokens — Ethereum, Base, and Arbitrum One, with USDC and USDT where available. Enable only the network/token pairs you want.
• Canonical token contracts — only official, checksummed USDC/USDT contract addresses are accepted, so look-alike tokens can never satisfy an order.
• QR code & EIP-681 deep links — customers can scan or tap to pre-fill the payment in their mobile wallet.
• Automatic order expiry — unpaid orders are auto-cancelled after one hour via Action Scheduler, with a “needs review” flag for payments that arrive late.
• Transaction details everywhere — network, token, tx hash, and addresses displayed on the thank-you page, order details, and admin order edit screen, with links to the block explorer.
• Email notifications — get notified as soon as a customer submits payment details.
• Change order status from email — no login required — admin email includes a secure Change Status link to view transaction details and update the order status without logging into wp-admin. Link expires after 2 days.
• HPOS compatible — works with WooCommerce High-Performance Order Storage.
• Block checkout support — fully integrated with WooCommerce Blocks checkout as well as the classic shortcode checkout.

Security notes

• The receiving address is validated before the gateway activates; leave it blank to disable the gateway entirely.
• Payments are reviewed by you before marking an order paid — submitted transaction hashes link directly to the block explorer so you can confirm the network, token, amount, and destination address in one click.
• The email Change Status link is HMAC-signed and expires after 2 days.
