Direct funding
A payer authorizes a deposit or transfer for the specific checkout. The platform observes funding evidence, evaluates eligibility and issues a guarantee only under supported conditions.
Prefunded spending
A payer may use a prefunded balance. The system must enforce balance reservation, idempotency and delegated spend policies before accepting a payment.
Merchant guarantee
A signed guarantee represents a provider commitment under a defined policy. It is not chain finality, and neither payout nor final reimbursement should be inferred solely from guarantee issuance.
Speed target
The product is designed to issue guarantees within one second for eligible paths. This is a performance target until measured and backed by a published service-level commitment.
