What is Recurring Payment?
A recurring payment is an automated, periodic transfer of funds — such as subscriptions, rent, or salaries — that in crypto requires specific smart contract mechanisms since blockchain transactions aren't natively push-based.
WHY IT MATTERS
Traditional recurring payments are simple: you authorize a charge, and the provider pulls funds monthly. On blockchain, there's no native 'pull' mechanism — transactions must be initiated by the sender. This makes recurring payments a design challenge.
Solutions include: ERC-20 approval-based pulls (approve a contract to spend your tokens periodically), account abstraction with scheduled execution, and smart contract subscriptions that auto-execute on trigger conditions.
Recurring payments are essential for mainstream crypto adoption — subscription services, payroll, rent, and installment payments all require reliable periodic execution.
HOW POLICYLAYER USES THIS
PolicyLayer's rolling budget policies naturally support recurring payment patterns. An agent authorized with a monthly budget of $5000 can execute subscription payments throughout the month, with the policy automatically resetting each period — enabling automated recurring operations within defined bounds.
