Stablevoy: USDT and USDC Crypto Payments for WooCommerce

Stablevoy is a non-custodial crypto payment gateway for WooCommerce. It lets your store accept USDT (Tether) and USDC (USD Coin), the two biggest stablecoins, so every price stays in US dollars and there is no volatility to worry about. Customers pay from their own crypto wallet, and the money goes straight to your wallet, not to an exchange or a payment processor account. Accept USDT TRC20 on Tron with no fee, USDT BEP20 and USDC on BNB Chain (BSC), and USDC and USDT on Base, Arbitrum, Optimism, Avalanche and Polygon, where network fees are cents. Customers pay with MetaMask, Trust Wallet, TronLink, Rabby or any other wallet, or by scanning a QR code from an exchange app. Features

• Connect in one click: sign in to Stablevoy with your wallet, choose or create a store, and come back with the API key and webhook secret saved and tested.
• Money goes straight to your own wallet. Stablevoy never holds it.
• USDC and USDT on Base, Arbitrum, Optimism, Avalanche, Polygon and BNB Chain, and USDT on Tron.
• Every order gets its own deposit address, checked in the customer's browser before payment.
• Orders move to Processing on their own once the payment is confirmed on chain; status changes arrive as signed webhooks.
• Underpaid, overpaid and late payments are recognised and noted on the order.
• Sender addresses are screened against the OFAC sanctions list.
• Works with the block checkout and the classic checkout, and with High-Performance Order Storage.

Pricing No monthly fee and no setup fee. The first $1,000 of payments is free, once per payout wallet. After that the fee is 0.5% per payment, taken on chain when the funds are forwarded to you, and the contract caps it at 2% forever. USDT on Tron has no fee from Stablevoy. How it works Each order gets its own deposit address, backed by an immutable contract that can only forward funds to your payout wallet (minus a fixed fee). Stablevoy never holds your money. On Tron (USDT TRC20, also written TRC-20) there is no contract at all: the customer pays your own wallet directly, an exact amount identifies the order, and Stablevoy takes no fee. A payment that arrives with another amount, for example from an exchange that took its withdrawal fee out of it, is listed in your Stablevoy dashboard for you to match to the order. On the payment page the customer can pay on Tron with TronLink in the browser or from a mobile wallet that supports Tron, such as Trust Wallet, over WalletConnect: the page prepares the transfer of the exact amount and the customer confirms it in the wallet. External service This plugin connects to the Stablevoy API (https://api.stablevoy.com, or the URL you configure) to create an invoice for each order and to read your invoice limits. It sends the order total, the order id and the order return URL. When you click Connect to Stablevoy, your browser opens https://stablevoy.com/app/connect/ with this shop's address, settings page address and webhook address; after you confirm there, the plugin sends a one-time code back to the Stablevoy API to receive the shop's API key and webhook secret. Disconnect asks the Stablevoy API to revoke that key. Stablevoy sends signed webhooks back to your site when a payment is confirmed.

1. Install and activate the plugin. Your store currency must be USD.
2. In WooCommerce, Settings, Payments, Stablevoy click Connect to Stablevoy.
3. Sign in to Stablevoy with your wallet, choose or create a store and confirm. You come back to the settings with everything saved and tested; click Turn on payments.

Manual setup still works: in the Stablevoy dashboard create a store and an API key, set the webhook URL shown on the gateway settings page, and paste the API URL, API key and webhook signing secret into the fields.

1.4.1

• The setup hints point to the new Integrations tab of the Stablevoy dashboard.
• The connect link names the platform, so the Stablevoy dashboard can tell this shop apart from other plugins on the same site.

1.4.0

• Connect to Stablevoy in one click: sign in, choose or create a store and come back with the key and webhook secret saved and tested. No more copying values between tabs.
• Disconnect revokes the shop's key on Stablevoy and clears it here.
• After connecting, a button turns payments on; the plugin never turns them on by itself.

1.3.1

• Clearer plugin name, tags and description in the plugin directory. No change in how the plugin works.

1.3.0

• USDT on Tron: the customer pays your own wallet directly, with no fee from Stablevoy. The order note says so.
• On Tron the customer can pay with TronLink or from a mobile wallet such as Trust Wallet over WalletConnect.

1.2.1

• Taking over a stale webhook lock is now atomic, so two deliveries can no longer both process the same order.
• Admin notices appear only on the Plugins screen and the WooCommerce settings screens.

1.2.0

• Paying again for an order after its invoice expired creates a new invoice instead of reopening the expired one.
• A late underpayment or hold notice no longer moves an already paid order back to on hold.
• Checkout stays fast when the Stablevoy API cannot be reached: the failed lookup is remembered for a minute and uses a short timeout.
• Buyers see a neutral message when a payment cannot be started; the details go to the order notes.
• Webhook deliveries for the same order are handled one at a time.
• The saved API key and webhook secret are never printed back into the settings page.
• Deleting the plugin removes its settings, including the API key and the webhook secret.
• All texts are translatable. The plugin folder and text domain are now stablevoy-for-woocommerce.

1.1.0

• Setup help on the settings screen, the shop's webhook URL with a copy button, and a Test connection button that checks the key, the webhook URL and the invoice range.

1.0.0

• First release.
