Sovereign Crypto Payments is a simple and free payment gateway for WooCommerce. No need to register anywhere, payments are made directly to your wallet without redirecting through a 3rd party website. You can either add a list of Bitcoin addresses or enter a Master Public Key (MPK), deriving a unique address for each order. MPK-mode currently only supports Legacy-wallets (xpub), while the regular mode works with all address formats (Legacy, Segwit, Bech32). This plugin is Bitcoin-only for now, more cryptocurrencies will be added soon. Next on the list is Monero.
Payments are verified in real-time via blockstream.info block explorer, orders are automatically set to processing after 1 confirmation. Bitcoin price is sourced from bittrex, poloniex and gate.io. Stores with non-USD currencies retrieve rates from exchangeratesapi.io.
