NSP Payment Options

Card checkout, Ghost/Lemon Squeezy status, SpaceCash devnet, and BTC/XMR invoice readiness.

Stripe card checkout
manual fallback

Stripe Checkout routes are implemented for paid products. If vault keys are absent, checkout falls back to an order inquiry.

Open lane
Ghost(Pro)
account found; billing review needed

Ghost is useful for publishing/memberships after the account is current, but it is not the safest immediate product checkout path.

Open lane
Lemon Squeezy
account found; payout tax form needed

Lemon Squeezy can be an alternate digital-goods checkout only after payout/tax setup is complete.

Open lane
SpaceCash
devnet only

Product redemption is wired to the local SpaceCash devnet ledger. Public/mainnet payment use stays blocked until manual evidence gates clear.

Open lane
BTC / XMR invoice intake
wallet env vars needed

No wallet address is hardcoded. Set NSP_BTC_ADDRESS and/or NSP_XMR_ADDRESS, then use manual invoice review until an audited gateway is selected.
