Couch

Stablecoin recurring payments made easy.

Couch is an offchain orchestrator for SpendPermission-based recurring payments. While SpendPermissions provide onchain authorization primitives, Couch handles the coordination layer: scheduling charges, managing subscription state, processing payments and delivering webhooks to merchants.
