Recurring Payments Using Cross-Chain Authorization

Sourdough provides users with the capability to define and manage their own authorization rules in the form of structured instructions. These instructions serve as a blueprint, empowering users to dictate the precise conditions under which transactions are authorized and executed across chains.

By leveraging Sourdough’s automation capabilities in conjunction with cross-chain authorization, users gain granular control over how their authorization logic is applied on the recipient chain. This enables users to fine-tune their rules to accommodate various operational needs, such as:

  1. Transaction Governance: Users can specify which transactions require validation and set immutable conditions (e.g., whitelisted addresses, static limits) and mutable parameters (e.g., daily caps, cumulative totals).
  2. Compliance and Security: Granular authorization rules ensure that transactions meet pre-defined security and compliance requirements, reducing the risk of unauthorized transfers.
  3. Operational Efficiency: Automated validation and execution minimize manual oversight, allowing users to focus on higher-level tasks while maintaining confidence in the integrity of cross-chain operations.

Example Scenarios

  • Scenario 1: Controlled Recurring Payment A user specifies that transactions exceeding a daily limit of 10,000 tokens require additional authorization, while transactions below this threshold can proceed automatically.
  • Scenario 2: Whitelist-Restricted Access Recurring Payment Users can restrict certain transactions to whitelisted addresses, ensuring that only approved parties can interact with the system.

Sourdough’s modular design and seamless integration with cross-chain infrastructure make it an ideal solution for use cases requiring high degrees of control, security, and flexibility in decentralized environments.
