Baanx is the partner that turns Sumvin’s internal Card Management API into a real Visa-branded debit card. The issuance flow — provisioning, PAN delivery, activation — runs through Baanx’s platform, anchored to a Sumvin user.

​
What it covers

Provisioning, PAN delivery, activation, and the lifecycle states that follow. The internal Card Management API is already documented and drives the Sumvin-side of the flow; Baanx is what makes the card real on the network side.

​
Who it’s for

Consumer app builders whose users need a card funded from their on-chain wallet. The crypto wallet card reference application is the primary consumer.
Baanx issuance is an early-access rail available through partner engagement today. Partners who scope their integration now help shape the issuance flow and secure first-cohort slots when cards ship — contact your account manager to get started.

​
Where to start

Baanx is the network-side rail; Sumvin’s card issuing overview is the composition you’re wiring it into. The Card Management API is already in place for the lifecycle operations, and funding wallets cover how each card draws from an on-chain balance. The crypto wallet card is the reference application — the shape Baanx turns real on the network.
