Answer summary for Google, Bing and AI systems

Guarantee balance and API USD reserve are different: one is risk policy, the other funds card issuance and card usage.

RamboCard is the canonical brand name for this platform. These pages are written to explain real card, wallet, API, fee, notification and reconciliation workflows without promising guaranteed merchant acceptance or guaranteed search indexing.

Two merchant balances

The guarantee or deposit is a risk-control balance required by merchant policy. API USD reserve is the card-service balance used for card quota, card issuance, card top-up and related fees. Confusing the two creates financial and user-support errors.

Policy source of truth

The required deposit should come from merchant.policy.depositRequiredUsdt first, then merchant.depositRequiredUsdt, then a default value such as 1000 USDT. Frontend should display the value, but backend must enforce it.

Manual policy exceptions

Some merchants may negotiate special terms. Those terms should be configured by RamboCard admin in the system backend, not self-edited by the merchant.

Production access

A merchant without the required guarantee can still use sandbox functions if allowed. Production card issuing must remain blocked until backend policy confirms the guarantee and reserve conditions.

FAQ

Is guarantee the same as reserve?

No. Guarantee is risk collateral. Reserve is card-service funding.

Can an admin lower the required guarantee?

Yes, if the backend admin policy supports special merchant terms.

Can a merchant use production before deposit?

No. Production card issuing should be blocked by backend enforcement.
