Between Bleap and Kast Card, Bleap clearly delivers more value. It’s a non-custodial Mastercard offering 2% cashback in USDC, no FX or ATM fees, and global acceptance. Kast, though functional, charges monthly and ATM fees and holds your funds in a custodial wallet, meaning you don’t fully own your crypto.
Kast Card is a custodial crypto card that allows users to spend their balance through Mastercard with basic cashback and standard fintech features. It offers a simple way to use crypto for everyday purchases, but follows a traditional top-up model with typical fees and custodial limitations.
Kast is a functional product for basic spending; however, Bleap stands out because it is fully non-custodial, charges zero FX or monthly fees, offers free ATM withdrawals, and delivers a real 2% cashback in USDC without tiers or conditions. In short, Bleap provides more transparency, more control, and significantly better value for users who want a truly modern crypto card.
Bleap is a global onchain account that connects your crypto wallet to a free Mastercard, enabling instant spending at over 90 million merchants.

Verdict: Bleap’s instant 2% cashback doubles Kast’s return and requires zero effort.
Bleap’s MPC Non-Custodial Model
Bleap uses Multi-Party Computation (MPC), your private key is split into multiple encrypted shares across devices and servers.
Even if one share is compromised, it’s useless without the others. Neither Bleap nor any provider can access your funds.
This ensures:
Kast’s Custodial Model
Your crypto is held by Kast or its banking partner. While convenient, it creates dependency on a third party for access, withdrawals, or policy compliance.
Unlike Kast, Bleap users retain total self-custody, your wallet, your funds, your control.
Both cards leverage Mastercard’s global network, but Bleap’s 1:1 stablecoin system removes FX costs, making it more efficient for frequent travelers and cross-border payments.
Bleap feels like a true “onchain account,” not a top-up card.
Final Verdict
Bleap is objectively the better choice for anyone who values transparency, autonomy, and long-term financial sovereignty. Kast remains a functional custodial card in Europe but cannot match Bleap’s combination of zero fees, non-custodial security, and consistent rewards.
Yes, currently in the EEA and Switzerland, with LATAM rollout planned for Q1 2026.

With 2% cashback, 0% FX, and non-custodial security, Bleap isn’t just another crypto card. it’s your borderless, onchain current account.
