Kast is a digital stablecoin payment platform that connects blockchain deposits with retail card networks. The service issues virtual and physical Visa debit cards so users can spend stablecoin balances at global merchants without a separate manual off-ramp for each purchase. In product terms it functions as a stablecoin neobank focused on multi-chain dollar access.
Kast operates as a custodial wallet application paired with payment processors. The company is privately held and converts balances through centralized liquidity paths. Revenue comes from membership fees on premium tiers, FX and ATM charges, and card economics.
How is Kast structured as a stablecoin platform?
Kast is a custodial digital wallet that bridges multi-chain networks to Visa authorization systems. It is not a licensed retail bank and does not offer government-insured checking deposits. The platform retains control of private keys for deposit wallets and handles compliance under applicable money-services frameworks.
Deposit architecture integrates Solana and Ethereum Layer 2 networks such as Arbitrum and Base. When users deposit USDC, USDT, or related stables, assets enter Kast-managed pools and the spendable card balance updates in the Visa stack. Pooling lets the company authorize retail payments without a user signature at the terminal.
Virtual USD bank account details can receive ACH and Fedwire deposits for freelancers and remote workers. Incoming USD is typically converted into USDC on the user’s balance. International payouts can convert stables into local currencies for bank delivery in many countries through regional partners.
How do the Kast Visa cards and banking features function?
Kast provisions an instant virtual card after KYC and supports physical cards by tier. Virtual cards can be added to Apple Pay or Google Pay where available.
As of mid-2026, published tier economics are approximately:
| Membership tier | Indicative cost | USD cashback (eligible spend caps) | Card / points notes |
|---|---|---|---|
| Standard | $0 / year | About 1.5% on first ~$2,000/month | Free virtual; physical Standard often free + shipping |
| Premium | About $1,000 / year | About 2% on first ~$10,000/month | Visa Infinite class; + points on spend |
| Limited / Private | About $5,000 one-time (varies) | About 3% on higher monthly caps | Elevated perks |
| Luxe | About $10,000 / year | About 3% on highest caps | Top metal / points rates |
KAST Points remain a parallel rewards track on higher tiers (for example about +1% to +2% points on spend in published tables). Seasonal point rates and token promotions change and should be read as campaign-specific.
What fees and transaction costs does Kast charge?
Standard accounts avoid annual fees but pay more per transaction on FX and ATM paths. Premium tiers trade high fixed fees for higher cashback and lower percentage frictions.
| Fee category | Standard (typical) | Premium / higher (typical) |
|---|---|---|
| Annual fee | $0 | $1,000+ / year (tier-dependent) |
| Foreign transaction / non-USD markup | About 0.5%–1.75% | Reduced on some plans |
| ATM withdrawal | About $3 + 2% + operator fees | Lower percentage or free bands |
| Stablecoin top-up | $0 | $0 |
| ACH / Fedwire funding | Flat fees (e.g. $2 / $15) | Same schedule unless waived |
| Inactivity | Small monthly fee after long idle periods in some schedules | Same |
Internal peer-to-peer transfers between Kast users are typically free. All figures above are as of August 2026 public help and marketing materials and can change.
Who is eligible for Kast and what are the account limits?
Kast markets availability across a large country set (on the order of 100–150+), aimed at global dollar utility including emerging-market corridors. Card activation requires KYC with government ID and residence checks.
Limits scale with verification and membership:
| Limit category | Standard (order of magnitude) | Higher tiers |
|---|---|---|
| Daily card spend | About $5,000 | Up to about $15,000–$25,000 |
| Daily ATM | About $500 | About $1,500–$2,500 |
| Monthly deposits | About $20,000 | $50,000 to unlimited with advanced KYC |
Exceeding monitoring thresholds can place transfers in compliance review.
What risks and custody tradeoffs does Kast present?
Because Kast is custodial, users do not hold deposit keys. Insolvency, freezes, or security incidents can block access to balances. Regulatory changes can force regional exits.
Purchasing power depends on stablecoin pegs; a depeg reduces card value immediately. Chain outages on Solana or L2s can delay deposits even if existing card buffers still authorize for a time. Cleared Visa transactions are not reversed through on-chain refunds alone.
Common questions
Is Kast a licensed bank?
Kast is a stablecoin platform and money-services style operator, not a commercial bank with FDIC-insured checking. Balances are custodial corporate-managed assets, not insured deposits.
How do cashback and KAST Points interact?
USD cashback (where offered) is capped by monthly eligible spend per tier. KAST Points accrue on a separate schedule and may unlock upgrades or seasonal utility; they are not identical to cash.
Can I use the card internationally?
Visa acceptance is global where the network works. Standard accounts typically pay a non-USD markup in the 0.5%–1.75% range unless a higher tier reduces it.
