Security Considerations

Security isn't a feature - it's fundamental to how Paygrid operates. Our approach combines programmatic controls, secure execution environments, and granular permissions to ensure your payment operations remain protected without sacrificing flexibility or performance.

• Idempotency is built by using one-time signature authorizations to ensure reliability and predictability in managing requests. The same payment intent request cannot be initiated twice using the same signatures. This mechanism protects against replay-attacks.

• Self-Custody: Ensuring that all parties involved in transactions maintain control over their funds which are never locked in the protocol at any time. This minimizes the risk of draining attacks and breaches from a central point of failure. Ensuring that transactions require explicit user approval via signatures schemes helps enforce this principle.

• Least-Privileges Access: Paygrid architecture is designed with this principle in mind, which makes sure that a user or entity should only have access to the specific data, resources and permissions needed to complete the payment flow. This dramatically reduces the attack surface allowing:

  • Granular access control

  • Time-bound permissions and authorizations

  • Revocable capabilities

• Infrastructure Security & Failsafes

  • Secure execution environment

  • Separation of concerns

  • Distributed and redundant infrastructure
