Bitcoin E-Commerce Payments
Accept Bitcoin and Lightning payments at checkout with instant confirmation, stablecoin settlement, and no chargebacks. Built for e-commerce platforms and payment gateways.
Traditional Bitcoin payments don't work for e-commerce
On-chain Bitcoin transactions are too slow for checkout flows, with confirmation times that frustrate customers. High on-chain fees make small purchases completely unviable. Merchants face volatility risk during the settlement window, often losing margin to price swings. Complex integrations require custom work for each payment method. Without stablecoin settlement options, treasurers are forced to manage Bitcoin exposure or immediately convert to fiat at a cost. These friction points prevent Bitcoin adoption at scale for online commerce.

FAQ
Lightning payments settle in under a second, while on-chain Bitcoin can take 10 minutes to an hour for sufficient confirmations. For e-commerce checkout flows, this means Lightning provides a credit card-like experience while on-chain Bitcoin would require customers to wait or merchants to accept zero-confirmation risk.
No. Spark handles all Lightning infrastructure including channel management, routing optimization, and liquidity provisioning. You integrate via simple API calls and receive/send payments without worrying about channel capacity or network topology.
When you receive a Lightning payment in Bitcoin, Spark can automatically swap it to USDT or USDB within milliseconds. This happens transparently in the background. Your treasury sees stablecoin balance instead of Bitcoin, eliminating price exposure. You configure settlement preferences once and Spark handles execution.
Bitcoin and Lightning payments are irreversible. There are no chargebacks like credit cards. Once a payment settles, it cannot be reversed by the customer or payment network. This eliminates chargeback fraud risk but means you need clear refund policies. Refunds are processed as new outgoing payments, not reversals.
Spark provides REST APIs and webhooks that plug into standard payment gateway architectures. You generate Lightning invoices via API, display QR codes to customers, and receive webhook callbacks when payments complete. For platforms like Shopify or WooCommerce, we provide plugins and reference implementations. Custom platforms typically integrate in under a week.
