Before installing SCC Payments, ensure your environment meets the following requirements.
Note: SCC Payments does not require any account registration with us. The plugin validates your license key against our server on activation, then operates fully on your own infrastructure.
Download the plugin zip from your purchase confirmation email or from your account dashboard.
In WordPress admin go to Plugins → Add New → Upload Plugin. Select the zip and click Install Now.
Click Activate Plugin. You will be prompted to enter your license key on the SCC Payments settings page.
Navigate to WooCommerce → Settings → Payments → SCC Payments to add your wallet xpub keys.
The free tier is available directly from the WordPress plugin directory. Search for "SCC Payments" in Plugins → Add New and install directly. No license key is required for the free tier.
The SCC Wallet Manager is a free native desktop application for macOS and Windows. It allows you to safely generate xpub keys from any seed phrase or existing wallet, without exposing your private keys to any server or internet connection.
Security: The Wallet Manager app never transmits your seed phrase or private keys. All derivation happens locally. We recommend using a dedicated wallet for receiving store payments rather than your personal spending wallet.
An xpub (extended public key) is the public component of your HD wallet. It allows SCC Payments to generate an unlimited sequence of unique receiving addresses — one per order — without ever having access to your private keys or the ability to spend funds.
Each blockchain requires a separate xpub key. You can enable as many or as few chains as you wish. Customers will only see the chains you have configured with a valid xpub at checkout.
All plugin settings are found under WooCommerce → Settings → Payments → SCC Payments.
For each chain, you can configure:
Bitcoin is supported via standard BIP44 derivation. Addresses are generated as native SegWit (bc1q...) by default for lower transaction fees.
Note: Bitcoin confirmation times average 10 minutes per block. We recommend setting a minimum of 1 confirmation for small purchases and 3+ for larger orders. The default is 2 confirmations.
Ethereum and ERC20 tokens (USDT, USDC) share the same address derivation path and xpub key. One xpub covers all Ethereum-based assets.
Note: Ethereum gas fees are paid by the customer at the time of sending. For small purchase amounts, USDT on Tron (TRC20) is generally a better choice due to near-zero fees.
USDT on Tron is the recommended stablecoin for most merchants. Transactions confirm in seconds with near-zero fees, making it ideal for any purchase amount.
Solana is supported for SOL payments. Fast finality and low fees make it a strong option for customers who prefer the Solana ecosystem.
Polygon shares the same xpub derivation as Ethereum. A single Ethereum xpub can be used for both chains simultaneously.
BNB Smart Chain (BEP20) is supported for BNB and BEP20 tokens. Also shares Ethereum derivation path.
Available on Business and Agency plans. Allows you to accept payments that are slightly below the order total — useful for handling exchange rate fluctuations between when the address is generated and when payment is sent.
Overpayments are automatically flagged in your WooCommerce order notes for manual review. The order is still marked complete — the extra amount stays in your wallet.
Each chain has a recommended minimum number of confirmations before an order is considered final. SCC Payments lets you configure these per chain under your payment settings.
Yes. A single BIP44-compatible seed phrase can derive xpub keys for all supported chains. The SCC Wallet Manager app handles this automatically.
Yes. Any HD wallet (Ledger, Trezor, Exodus, etc.) that knows your seed phrase will automatically discover addresses that have received funds during its sync process.
The address is still valid on the blockchain — funds sent to it will still arrive in your wallet. However, the plugin will not automatically match the payment to an order. You will need to manually match it via WooCommerce order management and mark the order complete.
No. SCC Payments charges zero percentage fees on transactions. The only fees are standard blockchain network fees, which are paid by the customer at the time of sending.
