Stablecoins for WooCommerce is a payment gateway for USD stablecoins. Customers pay in USDC, PYUSD, USDM or USDCx on Ethereum, Base, Solana or Cardano, and the money goes straight to wallet addresses you control. No custodian holds the funds, there is no conversion fee, and every payment is confirmed on-chain before the order is marked paid.

How a Stablecoins for WooCommerce payment works: the customer picks a token and network, pays from any wallet, the payment is confirmed on-chain and the order is paid

Supported stablecoins and networks

Ethereum: USDC and PYUSD.
Base: USDC, usually with network fees of about a cent.
Solana: USDC and PYUSD.
Cardano: USDM and USDCx.

You choose which tokens you accept and enter one receiving address for each network. Prices stay 1:1 with US dollars. If your store currency is not USD, the plugin converts the total with a live exchange rate.

Customers pay from the wallet they already use

Ethereum and Base: WalletConnect, so any mobile wallet can pay by scanning a QR code, plus browser wallets.
Solana: Phantom, Solflare and Backpack.
Cardano: Eternl, Lace and Vespr.
Send manually: the payment page shows the address, the exact amount and a QR code, for paying from an exchange or another device. A small unique figure in the amount matches the transfer to its order automatically.

Stablecoins for WooCommerce checkout: choose USDC, PYUSD, USDM or USDCx, pick a network and pay from WalletConnect

Pay right at checkout

With Pay at checkout turned on, the customer’s wallet opens as soon as they place the order and asks them to approve the exact amount, so most payments never need a separate payment page. Anyone who cancels continues to the payment page, which tracks the payment from waiting to detected to confirmed.

Confirmed on-chain, order by order

Before an order is marked paid, the plugin checks the transfer’s token, recipient, amount and age, and makes sure the same transaction was not already used for another order. Ethereum and Base payments are checked with Etherscan, Solana with Helius and Cardano with Blockfrost, using your own API keys.

If a customer sends the wrong amount, the order stays On hold. You can attach the transaction ID on the order screen: a small underpayment within the tolerance you set completes the order, and anything else is noted for you to settle.

Frequently asked questions

Where do the payments go?

Straight to the receiving addresses you enter. The plugin never holds funds or private keys.

Which stablecoins can customers pay with?

USDC and PYUSD on Ethereum, USDC on Base, USDC and PYUSD on Solana, and USDM and USDCx on Cardano. You can turn each one on or off.

Can I test it before going live?

Yes. Test mode uses Sepolia, Base Sepolia, Solana devnet and Cardano preprod with separate addresses, so you can place real test orders with free test tokens before switching to mainnet.

What happens if a customer sends the wrong amount?

Only the exact amount shown is matched automatically. Any other amount leaves the order On hold, and you can attach the transaction ID on the order screen to complete it, note the overpayment or collect the balance.

How do I get updates?

Activate the license key from your RyanPlugins Patreon membership on the plugin’s License tab. New versions then appear on the Plugins screen and can update automatically.
