FAQ

Questions? Answered.

Why Stellar?

Three things that don't exist anywhere else.

  • 01$0.00001 per transaction. Recurring micro-billing finally has economics that work. A $1 charge keeps 99.999% of revenue.
  • 02Single-signature subscribe. Soroban's auth tree bundles the contract call and the USDC allowance into one click. Impossible on EVM without account abstraction.
  • 03Native USDC. Circle issues directly on Stellar. No bridges, no wraps, no liquidity fragmentation.

EIP-1337 and EIP-948 both died because Ethereum gas killed the math. Stellar fixes that by construction.

Can I use Vowena without paying anything?

Absolutely. The Vowena smart contract and TypeScript SDK are completely free and open source. You can deploy the contract, create plans, subscribe users, and run your own billing keeper without paying us a cent. The Pro tier exists for teams who would rather focus on their product and let us handle the billing infrastructure.

What happens when beta ends?

We're keeping Pro free during the entire beta period and we'll publish paid pricing alongside the mainnet launch. Anyone who signed up during beta will get the most generous transition we can offer, with plenty of notice. We're not committing to a number until we have real merchant data to price against.

Can I switch between plans?

Yes, at any time. Your plans, subscriptions, and all on-chain data are completely independent of which tier you are on. Upgrading gives you access to the dashboard and automation instantly. Downgrading just means you go back to running things yourself.

What happens if I stop paying for Pro?

Nothing breaks. Your plans and subscriptions stay exactly where they are on the blockchain. Subscribers can still be charged and can still cancel. You just lose access to the managed keeper, analytics dashboards, and priority support. You can always switch to running your own keeper bot using the open source SDK.
