auto-draw-card implements an Algorand card-management system. A Main contract "generates" a rekeyed account for each card it creates, and all minimum balance requirements (box storage, account minimums, asset opt-in MBR) are pre-funded by the contract owner — the Partner operating the platform. Callers never attach MBR payments.
On top of the Main contract, two auxiliary components enable an opt-in automated debit ("AutoDraw") flow that card holders can disable at any time:
- Main — the card-management application (create/close/recover cards, debits, withdrawals).
- Killswitch — an application tracking which accounts have opted in to AutoDraw delegation.
- AutoDraw — a delegated
LogicSigthat authorizes an automatic debit from a card, gated by the Killswitch.
This is an AlgoKit workspace. The smart contracts live in projects/auto-draw-card — see that project's README for setup instructions and the full contract reference, role model, and lifecycle diagrams.
