What is Kast?
Kast is a more recent entrant in the crypto card space, offering an app and card for spending digital assets. Because it is newer and less documented, our verifiable data is thinner than for the long-running incumbents, and we would rather say so plainly than pad the profile with claims we cannot check. It ranks 11th of 15 in our Crypto cards category with a best score of 6, a placement resting mainly on strong responsiveness.
What we could measure
The standout signal is speed: our latency probe returned about 54 ms, among the fastest results across all the cards we track, which earns full performance marks. Against that, we could not confirm a public status page, and we have no long track record to credit, so its transparency and longevity scores are low. The overall rating reflects a fast but not-yet-established service. It is a common pattern for newer entrants: modern engineering shows up immediately in a snappy interface, while the slower-to-earn signals, years of uptime, published audits, a documented incident history, simply take time to accumulate. Our score will move as those materialize.
Approach with informed caution
- Limited history. Newer providers have not yet demonstrated resilience through multiple market cycles or incidents.
- No status page found. Outages are harder to verify without public incident reporting.
- Custody and terms unclear to us. Confirm the custody model, supported regions, and fees directly, as we could not verify them from public sources.
- KYC and tax. Expect identity verification, and remember that spending crypto can be a taxable disposal depending on where you live.
- Support maturity. Newer operations are still building out customer support and dispute handling, which matters most exactly when something goes wrong.
Who is it for?
Kast may interest early adopters who want a fast, modern card experience and are comfortable trying a less-proven provider. It is a weaker fit for anyone who prioritizes a long track record, public status reporting, or fully documented terms. We report only what we can verify; here that is strong responsiveness and little else, so do your own due diligence before relying on it.
