How we discount token rewards
We do not take a headline cashback percentage at face value when the reward is paid in a token rather than cash or a stablecoin, because that reward is a variable subsidy the issuer can reprice or that can simply lose value against the dollar. The worked math for Kast Card:
- 1. Headline cashback: 3%
- 2. Reward risk class: stablecoin → haircut multiplier 1.00 (stablecoin/fiat = 1.00, mixed = 0.70, native-token = 0.40)
- 3. Risk-adjusted rate = 3% × 1.00 = 3.00%
- 4. On $1,000 of monthly spend that is $30.00 of durable value, versus $30.00 of headline value that assumes the token reward never depreciates.
The 0.40 and 0.70 multipliers are deliberately conservative judgement calls, not a market-derived number — treat them as a floor on how much of the headline rate to trust, not a precise forecast.
Incident history and issuer risk
No publicly reported incidents on record as of 2026-08.
Young issuer dependent on third-party processors and a partner bank. Rewards are paid in stablecoins, which removes token-price risk from the reward itself.

Kast Card, answered
+ − Is the Kast Card headline rate the rate I will actually get?
Only if the reward is paid in stablecoins or fiat. Any reward paid in the issuer's own token is a subsidy that can be repriced or lose value, so the honest number is the risk-adjusted rate, not the headline one.
+ − What happens if Kast Card's issuer runs into trouble?
Read the custody model: a custodial card's balance sits on the issuer's books and is exposed to issuer insolvency; a self-custodial card removes that risk but adds smart-contract and key-recovery risk instead.
