Lightning and Liquid are always active. Optionally accept on-chain Bitcoin payments via Boltz Chain Swaps (BTC→L-BTC atomic swap).
The Bitcoin Onchain tab only appears on the checkout page when the order amount meets Boltz's minimum of 25,000 sats. Orders below this threshold show Lightning and Liquid only.
Shown as "Sold By" on buyer receipts across all payment channels (Commerce, WooCommerce, Shopify). Also used on AvoPay subscription invoices. Leave blank to show your account email only.
