A rewarded-offer app for West & Central Africa.

The product

What Blinko is

Blinko is a rewarded-offer application. Users complete advertiser-funded actions — installing and progressing in a game, answering a survey, watching a rewarded video — and receive BlinkoCoins, an in-app points currency. Coins are exchanged for rewards once a minimum threshold is reached.

Rewards are delivered over mobile money (Orange Money, MTN MoMo, Wave), which is the standard consumer payment rail in the region. This is a delivery method, in the same way PayPal or gift cards are elsewhere. Blinko is not a payment institution, does not hold customer funds, and does not offer money transfer between users.

Explicitly, we are not

• A payment service provider, e-wallet or remittance service.
• A gambling, lottery or prize-draw product. There is no wager, no deposit and no element of chance.
• An investment or income-generating scheme. Users are paid for actions they actually completed, at amounts disclosed beforehand.
• A cashback or shopping-rebate service tied to user purchases.

Quality & fraud

How we protect your conversion quality

Chargebacks are a cost to both sides. Our controls are built to reduce the conversions you would otherwise have to reverse.

Before an offer is shown

• Server-side geo resolution. Country is derived from the CDN edge header, never declared by the client. Users are never shown offers outside their eligible geography.
• Device and OS targeting enforced against the registered device, not a client-supplied value.
• Cross-partner deduplication. When the same advertiser offer reaches us from several partners, we show it once. This removes a structural source of duplicate conversions that can only ever be reversed.
• Completed offers are excluded from a user’s feed permanently.

Before a reward is released

• One account per mobile money number, enforced at database level at the point of exchange.
• Emulator and VPN signals flag an account for manual review.
• Velocity rules hold accounts that accumulate abnormally fast for their age.
• Excessive reversal history suspends further earning pending review.
• Manual review queue for high-value exchanges, with a full audit trail on every decision.

Accounting

• Append-only ledger. No balance is ever edited in place; corrections are counter-entries with a recorded reason and operator.
• Signed, idempotent postback handling. A replayed callback never credits twice.
• Reversals are honoured in full, including after payout, and are reflected in the user’s balance.
