Akyedie
A gift card platform where the money math is provably correct.
A gift card platform for the Ghanaian market. Buyers purchase cards through Paystack, recipients redeem them at partner vendors or cash out to Mobile Money, and vendors are settled weekly. Four surfaces (buyer, vendor portal, admin panel, webhooks) run from one codebase, routed by subdomain.
What it does
- 01All money held as integer pesewas, so no float ever touches a balance
- 02Every balance change runs inside a database transaction with a row lock, so double-spend cannot happen
- 03Financial records are append-only: a void is a new row, never an edit to the original
- 04Fee rates are stamped onto each transaction, so changing a rate never rewrites history
- 05Webhooks deduplicate on the provider reference, so a replayed event is a no-op
