Custody, Security, and Transparency

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:

• No single point of failure.
  
• True ownership and privacy.
  
• Zero custodial risk.
  

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.

Regional Coverage and Currency Support

• Bleap: Operates across the EEA and Switzerland, with LATAM expansion planned for Q1 2026. The LATAM rollout will include Brazil, Colombia, Mexico, and Argentina, supporting all major local currencies (BRL, COP, MXN, ARS) alongside EUR, USD, and multi-chain stablecoins.
  
• KAST Card is available in many countries (150+ claimed). However, terms, fees, issuance and physical card availability vary by country and issuing partner
  

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.

User Experience & App Design

Bleap feels like a true “onchain account,” not a top-up card.

Verdict: Which Card Is Better?

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.
