Short answer
Building subscriptions on a non-custodial protocol means your business offers recurring payments without holding customers' funds: payments follow public smart-contract rules, customers keep the power to cancel, and merchants can withdraw accrued revenue whenever they want. With Papaya Protocol (papaya.finance), that also means per-second billing and a subscription cost that does not grow with the number of billing periods. The trade-offs, such as no chargebacks and dunning you build yourself, are real and worth planning for.
1. Customer trust that does not depend on promises
Customers increasingly ask who can touch their money. With a non-custodial protocol, the answer is written in code anyone can read. In Papaya Protocol, the user grants a spending permission and can revoke it at any time. 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). For your business, this is a clear, checkable answer to put in your FAQ, instead of a policy customers must take on trust.
2. Cancel-any-time control builds goodwill
Subscriptions that are hard to cancel frustrate customers. With per-second streams, cancelling stops payment immediately, and the customer pays only for the time they were subscribed. That makes it easier to offer honest, low-friction pricing, and customers can withdraw what remains in their balance.
3. Revenue you can access at any time
Merchants do not wait for a payout schedule. Authors and project owners see their balance grow as subscriptions accrue and can withdraw at any time in one transaction, no matter how many subscribers they have (how it works).
4. No billing engine to run
Traditional recurring billing needs scheduled jobs, retries and reconciliation. In Papaya Protocol there is no batch transaction and no keeper that charges users one by one; balances are calculated from rates and time. Between user actions, accrual requires no transactions, which is why the cost of a subscription does not grow with the number of billing periods.
5. Open, fixed rules
Papaya Protocol contracts are non-upgradeable, and the owner cannot pause them or move user balances. For a business, fixed rules mean the payment layer under your product will not change without notice.
6. A revenue model for platforms
If you run a platform, each project can set a default fee and different fees for specific authors; the fee flows to the project owner the same way the payment flows to the author. A third party, such as the app, can fund a user's balance on their behalf, which supports trials, promotions and employer-paid plans.
7. Pricing models cards make hard
Per-second streams make usage-based, time-based and pay-as-you-go pricing natural: access while a stream runs, tiers by rate, and payments from AI agents whose funded balance caps what they can spend (use cases).
8. Reach wherever your customers hold stablecoins
Papaya Protocol runs on supported EVM chains: Ethereum, BNB Chain, Polygon, Base, Scroll, Sei, Avalanche, Arbitrum, zkSync, and Arc, with one contract per stablecoin per network. Customers pay from their own wallets in stablecoins they already hold. Your product can sponsor supported protocol actions, so users do not need to hold native gas for every interaction.
| Business question | Custodial billing provider | Non-custodial protocol (Papaya Protocol) |
|---|---|---|
| Who controls customer balances | The provider, under its terms | A non-upgradeable smart contract under public rules |
| How customers cancel | Through the merchant or provider | Directly; payment stops immediately |
| When merchants can access revenue | On the provider's payout schedule | Any time, in one transaction |
| Who runs the billing schedule | The provider or merchant | Nobody; balances are calculated from rates and time |
| Can the rules change | Under the provider's terms | No; contracts are not upgradeable |
The trade-offs to plan for
A persuasive case is only useful if it is honest. Before you build, plan for:
-
No chargebacks. Onchain payments are final; refunds are a separate payment from the merchant.
-
Dunning is yours. There is no grace period, automatic retry or reminder system in the protocol; build reminders off-chain (balance, refill and liquidation).
-
Balances must stay funded. Use deposits in advance, funding on behalf of users, or automatic refill from the user's wallet.
-
Smart contract and stablecoin risk. Balances for a stablecoin on a network sit in one contract, and balances inherit the risks of the deposited stablecoin.
-
Compliance stays with you. Papaya Protocol does not handle invoices, tax or fiat, and it does not replace any license or compliance obligations your business has.

-
Creator and community platforms with global audiences.
-
