consumer apps shipped: referral and loyalty
Live pilot
proved the model end to end
The problem
Loyalty points die inside the merchant that issued them. For a consumer startup, the bet was interoperability: a discount earned with one merchant should be spendable across others. That means the rewards themselves have to be portable, not rows in one company’s database.
What we built
The entire stack, on Ethereum: custodial wallets, custom interoperable tokens with a dedicated discount token per participating merchant, and two consumer apps, one for referrals and one for loyalty.
The outcome
A live pilot proved the model end to end: earn a discount with one merchant, spend it with another, with every reward held in the user’s wallet.
