Payments are self-custodial and require no Lightning node, no channels, and no liquidity management. ## Where checkout payments land Your customers pay through the regular BTCPay checkout and see nothing new. Behind the checkout, the plugin splits payments across two wallets: * **Lightning and Ark payments:** Arrive in your store's Bark wallet. * **On-chain payments:** Arrive in your store's native BTCPay wallet, exactly as before the plugin.
