STARs

STAR is the cashback voucher within Ouroboros ecosystem, designed to track and facilitate the distribution of user rewards earned through on-chain spending. For every $10 in cumulative transaction taxes paid, users receive 1 STAR voucher. Holders of STAR are entitled to receive cashbacks for up to 100 periods, after which the voucher expires.

$10 in tax — 1 STAR

Higher spending results in greater STARs. And the number of STARs directly determines the cash back rewards users can receive. For instance, under the 10x cashback multiple, a 100 USDO payment (with a 10 USDO tax) yields 1 STAR, unlocking eligibility for up to 100 USDO in cashback.

Non-Transferrable

STAR tokens are soulbound, non-transferable, and exclusively tied to the original recipient’s wallet address. This ensures that cashback rewards are reserved solely for the user who made the qualifying purchase, preventing speculative trading and reinforcing the integrity of the incentive system.

Functionally akin to soulbound NFTs, STARs record critical metadata—such as consumption amount, issuance timestamp, and cashback period progress—serving as the smart contract’s basis for reward distribution. Cashback claims are also strictly restricted to the bound account.

Vested Cashback Rewards

Ouroboros cashback rewards are vested and will be distributed for claim incrementally over up to 100 periods. Each STAR represents a predetermined cashback allocation, and functions similar to a mining node with rewards being released progressively to ensure sustained user engagement. Expired STARs remain in the user’s account, contributing to VIP tier evaluations.
