Stablecoin subscriptions: separate renewal from paid access
A customer pays 30 USDC for a month of access. Two weeks later, they cancel. Your app receives the cancellation event and flips is_active to false . Now they're locked out of time they already paid for. For a stablecoin subscription, track three things separately: whether a payment succeeded, whether another payment is scheduled, and how long access lasts. A single active flag can't answer all…
The article emphasizes the importance of separating the renewal status from the paid access period for stablecoin subscriptions. It suggests tracking three distinct aspects of a subscription: whether a payment has succeeded, whether a subsequent payment is scheduled, and how long access lasts. The author uses an example of a monthly plan costing 30 USDC, which covers a specific timeframe, and illustrates how cancellation affects access.
It also highlights the need for explicit end boundaries and the importance of using canonical identifiers for tokens to validate transfers. The article concludes by detailing the various events that can occur during a subscription, such as renewal, payment failures, and cancellations, and how each should be handled to ensure the customer's access is managed correctly.
