Recurring USDC Subscriptions

Let users pay for newsletters, SaaS, DAO memberships, and signal services in USDC straight from their wallet, with no custodian.

A non-custodial subscription protocol. A subscriber authorizes a capped, expiring allowance to a plan, a keeper charges each billing period, and the subscriber can cancel any time.

• 01Plan registry with price, period, and merchant.
• 02Subscribe with a capped, expiring token allowance.
• 03charge() callable once per period by anyone.
• 04Cancel or pause at any time.
• 05Merchant dashboard of active subscribers.

Rust contract using SEP-41 approve and transfer_from, with period checks against the ledger timestamp. Soroban has no native cron, so run a keeper or relayer. Frontend with Freighter or Stellar Wallets Kit.

Turns USDC on Stellar into a recurring-revenue rail, not just a one-off payment rail.
