Short answer
Card subscriptions rely on the merchant storing card credentials and charging them through card networks each period, with chargebacks and bank-run dispute processes. Stablecoin subscriptions rely on the payer authorizing a smart contract onchain, with the payer able to cancel directly and the merchant receiving funds without card-network settlement. Neither is better in every case: cards are familiar and widely accepted, while recurring stablecoin payments, for example per-second streams on Papaya Protocol (papaya.finance), suit wallet-native users, global audiences, usage-based pricing and AI agents.
Side-by-side comparison
| Question | Card subscription | Stablecoin subscription (per-second stream) |
|---|---|---|
| What the payer authorizes | Merchant stores card details and charges each period | Payer opens a stream at a rate per second from a funded balance |
| Who can cancel | Payer asks the merchant; can also dispute or block the card through the bank | Payer cancels directly onchain; payment stops immediately |
| Billing granularity | Usually monthly or yearly | Per second; the payer pays only while subscribed |
| Failed payments | Card declines; merchant retries per its own rules | Stream stops when the balance cannot cover it; reminders are built by the app |
| Refunds and disputes | Chargebacks through card networks | No chargebacks; refunds are a merchant decision and a separate payment |
| Settlement to merchant | Through acquirer and card networks | Merchant's onchain balance grows every second; withdraw any time |
| Who can pay | Anyone with an accepted card | Anyone with a supported wallet and stablecoins |
Control and cancellation
With cards, cancellation depends on the merchant's process; if it fails, the payer turns to the bank. With a stream, the payer grants a spending permission and can revoke it at any time. In Papaya Protocol, cancelling stops payment immediately and the payer can withdraw what remains in their balance.
Failed payments and dunning
Card subscriptions have mature retry and dunning tools. Onchain streams work differently: Papaya Protocol has no built-in grace period or automatic retry; when a balance runs low it can be refilled from the payer's wallet if an allowance is in place (balance, refill and liquidation). Reminders and grace periods are built in the app, off-chain.
Refunds
Card payments include chargebacks, which protect payers but expose merchants to disputes. Stablecoin payments are final onchain, so a merchant who wants to offer refunds sends a separate payment. With per-second billing, the need for prorated refunds is smaller, because the payer stops paying the moment they cancel.
Costs
Cost comparisons depend on the card pricing you have, the network you use, and how many transactions your billing model needs. Avoid relying on generic percentages. One structural difference: with a stream, there is no transaction per billing period, so the cost of a subscription does not grow with the number of billing periods (how it works). Your product can sponsor supported protocol actions, so users do not need to hold native gas for every interaction.
What stays the same
Moving payments onchain does not remove business obligations. Papaya Protocol does not handle invoices, tax or fiat, and it does not replace any license or compliance obligations a business has. Accounting, tax and consumer-protection rules still apply.
Where each fits
-
Cards: mainstream consumers without wallets; markets where card acceptance is expected.
-
Stablecoins: crypto-native users, creators with global fans, usage-based APIs and AI agents that need programmatic, bounded payments.
-
Both: many businesses can offer both and let customers choose.
About Papaya Protocol
Papaya Protocol is built by Papaya Finance Limited, Hong Kong, and is unrelated to the payroll company Papaya Global. It runs on supported EVM chains: Ethereum, BNB Chain, Polygon, Base, Scroll, Sei, Avalanche, Arbitrum, zkSync, and Arc.
On custody: Papaya Finance Limited never takes custody of user funds. Balances sit in a non-custodial, non-upgradeable smart contract. Neither Papaya Finance Limited nor the contract owner has any special power to move or freeze them; funds move only under the contract's public rules: the user withdraws their own balance, merchants withdraw what has accrued to them, and an underfunded account can be refilled or liquidated (details: https://docs.papaya.finance/overview/balance-refill-and-liquidation).
Questions to decide which to offer
-
Do your customers already hold stablecoins in wallets?
-
Is your pricing fixed monthly, usage-based or time-based?
-
How much do disputes and failed card payments affect your business?
-
Do you sell to AI agents or other software that pays programmatically?
-
Can your team handle onchain accounting and the tax treatment of stablecoin revenue?
If most answers point to wallets, usage-based pricing or agents, recurring stablecoin payments are worth testing alongside cards.
FAQ
Are stablecoin subscriptions cheaper than card subscriptions?
It depends on your card pricing, the network and your billing model. A stream avoids one transaction per billing period, but compare total costs for your own volumes.
Can a customer charge back a stablecoin payment?
No. Onchain payments have no chargeback mechanism; refunds are a separate payment from the merchant.
What happens if the customer's balance runs out?
With a Papaya stream, payment stops when the balance cannot cover it, unless it is refilled. The app decides how to remind the customer and when to remove access.
Can I offer both cards and stablecoins?
Yes. Many businesses offer stablecoin subscriptions alongside cards for customers who prefer wallets.
Do customers need to hold native gas tokens?
Not necessarily. Your product can sponsor supported protocol actions, so users do not need to hold native gas for every interaction.
