Reserve Fund

I. Overview

Merchants with custody fund licenses can manage their own reserve fund and do not need the platform to manage it for them.

Terminology

• Reserve fund: Funds used for cardholder spending, card issuance, and unified logistics payouts; managed by the merchant.
• Reserve ratio: Reserve fund ÷ total member assets; used to measure funding coverage and transaction success rate.
• Total member assets: Total value (USD) of digital assets held by members.
