At a Glance: Bleap and Kast Card in 2026

Kast Card: Solana-Powered Stablecoin Spending

Kast Card is a custodial prepaid Visa that converts stablecoins and selected crypto into a USD-denominated balance, then lets you spend through a virtual or physical card in over 170 countries. Its key differentiator is its Solana-first architecture, where top-ups flow through the Solana network (USDC, USDT, and SOL), delivering near-instant settlement and sub-cent gas fees. Following an $80M Series A announced in May 2026, the platform now serves more than 1 million users across 170+ countries and processes close to $5 billion in annualized transaction volume.

Kast positions itself as a stablecoin-first spending tool. You load USDC, USDT, SOL, or other supported assets, and Kast converts them into a spendable USD balance. The card works anywhere Visa is accepted, with Apple Pay and Google Pay support from day one.

Bleap: The Self-Custodial Spending Card

Bleap takes a fundamentally different approach. It is a fintech card company that connects your self-custodial account to a Mastercard debit card you can use anywhere Mastercard is accepted. The critical difference: your funds stay under your control at all times. There is no monthly subscription, no FX fees, and you earn up to 20% cashback on gaming, streaming, and everyday spending. It is a debit card you can use on Steam, PlayStation, or Xbox, with up to 20% cashback.

Bleap also offers fee-free crypto trading with no gas costs and no spread markup, plus savings vaults in USD: Steady at 3.65% AER (lowest risk) and Dynamic at 3.83% AER (low risk), both starting from just $1.

Verdict: For users who prioritize self-custody and zero FX fees, Bleap wins on fundamentals. Kast offers broader country availability and Solana-specific integrations that appeal to SOL-heavy portfolios.

Plans, Pricing, and Subscription Costs

Kast Card: Free Entry, Expensive Upgrades

Kast's Standard tier costs $0 annually. Premium costs $1,000/year, Limited costs $5,000 one-time, and Luxe costs $10,000/year. The Standard card was previously paid, but Kast made it free as of early 2026.

For most users, the Standard tier is the right entry point. The premium tiers only make financial sense if you are spending enough that the extra KastPoints percentage covers the annual fee. Quick math on Premium ($1,000/yr): you need to spend at least $33,333/yr to break even on the extra 3% KastPoints versus Standard.

Beyond the subscription fee, watch out for smaller costs that add up. There is a $0.50 declined transaction fee that is not in the headline numbers but adds up if your balance management is sloppy. A small transaction surcharge adds $0.10 to any non-USD purchase under $25. An inactivity fee of $1/month kicks in after 12 months of dormancy.

Bleap: No Subscription, No Compromise

Bleap has no monthly subscription and no annual fee. There are no hidden charges layered on top of your spending, no inactivity fees, and no declined transaction penalties. The Mastercard debit card is included, and you get fee-free crypto trading alongside it.

For a European user spending primarily in euros, the cost difference is straightforward: with Bleap, you pay €0 in subscription costs regardless of how much or how little you spend.

Verdict: Kast's Standard tier is free, which is a fair starting point. But Bleap is free with no conditions, no premium tiers to upgrade into, and no micro-fees to watch. If simplicity matters, Bleap costs less in practice.

FX Fees and International Spending

Kast Card: 0% in USD, Up to 1.75% Everywhere Else

The single most important thing to know about Kast: it charges zero fees on USD transactions. Load USDC, spend at Amazon, Uber, Netflix, or any USD-priced merchant. The FX fee only kicks in when you spend in euros, pounds, yen, or any non-USD currency.

Spending in a foreign currency carries up to 1.75% FX fee on the Standard tier. For a European user, this means every time you spend in EUR, you lose up to 1.75% on the conversion. On a €1,000 monthly spend in euros, that is up to €17.50 gone in FX fees alone.

Kast ran a promotional FX credit from April 1 to June 30, 2026, where eligible users could get 0% FX on qualifying local card spend through a promotional credit. However, this works as a credit back, not as an instant fee removal at checkout. Once the promotion expires, the standard FX fee applies again.

Bleap: 0% FX Fees, No Caps, No Weekend Markups

Bleap charges 0% FX fees. Not 0% on specific currencies, not 0% during a promotional window, not 0% up to a certain limit. Zero percent on every purchase, in every currency, at every time of day, permanently. There is no weekend markup, no cap, and no promotional asterisk.

For a European user spending abroad, say shopping in London, dining in Tokyo, or subscribing to a US-based service, every transaction goes through at the real rate with no markup. That is the kind of cost difference that compounds across months of everyday use.

Kast vs Bleap: FX Cost on €1,000 Monthly Spend (Non-USD)

Verdict: If you spend exclusively in USD, Kast matches Bleap on FX. The moment you spend in any other currency, Bleap saves you up to 1.75% on every transaction. For European users, that makes Bleap the clear choice.

Every euro you spend abroad should go further, not shrink. Bleap gives you 0% FX fees on every purchase and up to 20% cashback. No caps, no weekend markups, no promotional windows. Self-custodial Mastercard, no monthly subscription. Get the Bleap card →

Cashback and Rewards

Kast Card: Complex Tiers, Variable Returns

Kast's rewards system has evolved significantly. As of May 2026, Kast launched USD stablecoin cashback: Standard gets 1.5% on up to $2,000/month, Premium gets 2% on up to $10,000/month plus 1% KAST Points uncapped, and Private gets 3% on up to $40,000/month plus 2% KAST Points uncapped.

Cashback has a 14-day holding period before redemption and cannot be withdrawn or sent externally. It is only usable for eligible Kast card purchases. This is an important detail: your cashback is locked inside the Kast ecosystem for spending only.

In practice, the realistic effective rate for most users on the free tier is around 1.5%. The higher rates require either paying $1,000+ per year for Premium or spending through specific promotional seasons.

Bleap: Up to 20% Cashback, No Paid Plan

Bleap offers up to 20% cashback on gaming, streaming, and everyday spending. You get this on the free plan, with no monthly subscription, no paid tiers to unlock, and no holding periods restricting what you can do with your rewards.

The difference in structure is significant. Kast's cashback is capped by tier and locked for 14 days. Bleap's cashback comes with no subscription requirement and applies to categories that matter for everyday users: Steam, PlayStation, Xbox, streaming services, and more.

Cashback Comparison

Verdict: Kast's 1.5% cashback on the free tier is respectable but comes with caps and a 14-day lock. Bleap's up to 20% cashback on gaming and everyday categories, with no subscription and no lock, offers a higher ceiling for most spending patterns.

Custody and Control

Kast Card: Custodial, Provider Holds Your Funds

This is where the two cards diverge most sharply. Kast Card is a pre-funded card. You transfer crypto or stablecoins to a balance held by the provider, which the card then spends from. This is custodial: the issuer controls the funds while they sit there.

Kast operates a fully custodial model where deposited crypto is legally sold to Kast and managed at corporate treasury level. Users no longer retain ownership of transferred assets, creating counterparty risk. Partners are not required to segregate funds from Kast's other accounts unless otherwise agreed.

Kast explicitly states that funds are not insured by government deposit protection schemes. In the event of failure, bankruptcy, or liquidation, users may not be protected and may not recover funds, as they become unsecured creditors.

Bleap: Self-Custodial Security

Bleap is a self-custodial Mastercard. Your funds stay in your account, under your control, at all times. No third party can unilaterally move your money or restrict your access. This is a fundamental architectural difference, not a marketing detail.

Self-custodial means you are not exposed to the same counterparty risk that comes with custodial models. If you have been in crypto long enough to remember exchange collapses and frozen withdrawals, the distinction matters. With Bleap, your keys, your funds.

Verdict: For users who value ownership of their assets, Bleap is the only option in this comparison. Kast's custodial model trades control for convenience. Bleap gives you both.

Savings and Earn Features

Kast Card: Dual Vault System, Variable Rates

Kast Earn offers a USD Prime Vault (up to 3.3% APY) and a Gauntlet Alpha Vault (up to 7.0% APY). The USD Prime Vault is backed 1:1 by U.S. Treasuries. When you deposit, your USD converts 1:1 into USDKY, which is held in your own Privy wallet. As the Treasuries earn yield, that yield is reflected in the value of USDKY over time.

The Gauntlet Alpha Vault has a variable APY between 4-9%, and your funds stay in your onchain smart wallet, always under your control. This vault uses DeFi lending strategies, which carry higher risk alongside the higher potential return.

There are no deposit caps or lockups. The APY is variable and reflects current performance, so it may fluctuate and is not guaranteed.

Bleap Savings Vaults: 3.65% / 3.83% AER

Bleap offers 2 USD savings vaults with transparent, labeled risk levels:

• Steady vault: 3.65% AER (lowest risk), powered by Sky/Lido
• Dynamic vault: 3.83% AER (low risk), powered by Yo

Both start from just $1 minimum deposit, charge 0% withdrawal fees, and have no lock-in periods. EUR savings are coming soon.

The key difference is clarity. Bleap labels each vault with its risk level and presents a stable AER figure, while Kast's Gauntlet vault quotes a wide range (4-9%) that fluctuates with DeFi market conditions.

Savings Comparison

Verdict: Kast's Gauntlet vault offers a potentially higher ceiling, but it comes with DeFi exposure and rate volatility. Bleap's vaults offer predictable, labeled-risk returns with a $1 entry and zero withdrawal fees. For savers who want consistency, Bleap is simpler and more transparent. For those comfortable with DeFi risk, Kast's Alpha Vault offers higher upside.

Crypto Trading

Kast Card: No Built-In Trading

Kast is primarily a spending tool. Kast does not charge any fees for receiving supported stablecoins, but any non-stablecoin you deposit will be automatically converted into stablecoins. If you deposit non-stablecoin assets like SOL, Kast auto-converts them at a conversion fee of 2% to 5%.

There is no built-in trading feature. You buy your crypto elsewhere, deposit it into Kast, and spend it. The conversion cost on non-stablecoin deposits adds friction for anyone who does not already hold USDC or USDT.

Bleap: Fee-Free Trading, Self-Custodial

Bleap offers fee-free crypto trading with no trading fees, no gas costs, and no spread markup. You can buy and sell crypto directly in the app, gasless across supported networks including Solana and Arbitrum, and everything stays self-custodial from day one.

This means you can go from buying crypto to spending it with your Mastercard in a single app, without paying fees at any step. For users who want an all-in-one experience, this removes the need for a separate exchange account entirely.

Verdict: Kast is not a trading platform. Bleap gives you fee-free trading and self-custodial spending in 1 place. If you want to buy, hold, and spend from a single account, Bleap covers the full loop.

Card Network and Merchant Acceptance

Kast Card: Visa

Kast cards are accepted at 150 million merchants in 170+ countries. The card runs on the Visa network, supporting both physical and virtual card options with Apple Pay and Google Pay. The virtual card can be live within minutes of approval.

Bleap: Mastercard

Bleap runs on the Mastercard network, accepted at over 90 million merchants globally. The self-custodial Mastercard works anywhere Mastercard is accepted, both online and in-store.

Bleap: Built for Card Spending

Neither card is optimized for ATM withdrawals. Kast's ATM limits are $750 per day across 3 withdrawals, capped at $250 per transaction, with each withdrawal costing $3 + 2% in Kast fees, plus any third-party operator surcharge. Bleap is designed primarily for card-based spending rather than ATM cash access.

Verdict: Kast offers broader merchant coverage through Visa and wider country availability across 170+ countries. Bleap covers the EEA with Latin American expansion underway. For European users, both networks provide strong acceptance. For global travelers frequently outside Europe, Kast's 170+ country availability is an advantage, though the FX fees on non-USD spending reduce its value abroad.

Security Model

Kast Card: Custodial With Enterprise Partners

Kast partners with Fireblocks, BitGo, and enterprise security leaders for institutional-level protection. Multiple defense layers and continuous threat monitoring keep assets secure.

The security infrastructure is robust, but because the model is custodial, your protection depends entirely on Kast and its partners maintaining their systems. Your funds are held by Kast. If the provider faces insolvency, your balance may be at risk. The card does not offer self-custody protection.

Bleap: Self-Custodial Security

Bleap's security model starts with self-custody. Your funds are in your account, protected by your keys. No third party holds your balance or can restrict your access. This eliminates counterparty risk at the architectural level rather than relying on a provider's operational integrity.

Verdict: Kast uses enterprise-grade security partners, but the custodial model introduces counterparty risk. Bleap eliminates that risk by design. If custody matters to you, and it should, Bleap is the safer structural choice.

Your crypto. Your keys. Your card. Bleap's self-custodial Mastercard means your funds stay under your control. 0% FX fees, up to 20% cashback, fee-free trading, and savings vaults at 3.65-3.83% AER. No subscription. Open a Bleap account →

FAQ

Is Kast Card self-custodial?

No. Kast Card is a pre-funded card. You transfer crypto or stablecoins to a balance held by the provider, which the card then spends from.

No. Bleap charges 0% FX fees on every transaction, in every currency. There are no caps, no weekend markups, and no promotional conditions.

Does Kast Card work in Europe?

As of 2026, Kast Card is available to residents of the United States, United Kingdom, Europe, Canada, Latin America, Asia-Pacific, and Middle East & Africa. However, the FX fee kicks in when you spend in euros or any non-USD currency, which adds up to 1.75% on every transaction for European users.

Which card is better for European users spending in EUR?

For a European user, Bleap is the more cost-effective choice. You pay 0% FX fees on EUR spending, earn up to 20% cashback, and keep full self-custody of your funds, all with no subscription. Kast charges up to 1.75% on every EUR transaction, which erodes the 1.5% cashback on the Standard tier.

Conclusion

If you came here to choose between Kast Card and Bleap, the right answer depends on your spending patterns and priorities. Kast fits a specific profile: USD-first spenders, SOL holders, and users who need card access in 170+ countries. Its free Standard tier is a reasonable entry point, and the Solana ecosystem integration has genuine value for the right user.

But for most European users, and anyone who regularly spends in non-USD currencies, Bleap delivers more value at every level. Zero FX fees instead of up to 1.75%. Up to 20% cashback instead of 1.5% with caps and lockups. Self-custodial instead of custodial. Fee-free crypto trading instead of conversion fees. Savings vaults at 3.65-3.83% AER with a $1 minimum and 0% withdrawal fees.

If control, cost savings, and a genuinely fee-free experience matter to you, get the Bleap card and start spending with 0% FX fees and full ownership of your funds.
