full primer →The primitive.
Musicians pay a few sats over Spark (Bitcoin L2) via a single Privy-signed transfer to unlock the podcast audio authenticity; settlement is instant and the merchant confirms via getBalance.
Why this primitiveA Spark sats transfer settles in under a second and is Bitcoin-native — perfect for gating this content behind a one-click, low-friction micropayment.
Kernel
a 'pay N sats on Spark to unlock' gate — the user signs a Spark transfer via Privy, the merchant's wallet observes the transfer via Spark's getBalance/getTransfers, and the endpoint releases the payload
Drives the UI as
a 'pay 100 sats to unlock' button that returns the Spark tx id, the merchant confirmation, and settles instantly
