Non-custodial
Payments move wallet to wallet. Turbine never holds your funds.
Settles in seconds
USDC lands in your wallet the moment a subscriber approves.
Signed webhooks
Every event carries an HMAC-SHA256 signature, timestamp and idempotency key.
Nothing to build
A hosted checkout page and dashboard come with every business you publish.
Why Turbine
Card billing was built for one country's banks. Your customers are everywhere.
Every card processor draws a border around who can pay you, then takes a cut and holds the money for days. Stablecoins remove the border. Turbine adds the recurring part: plans, checkout, renewals and the records you need to run a business on it.
| Aspect | Card processors | Turbine |
|---|---|---|
| Who can pay | Customers in supported countries | Anyone with a wallet and USDC |
| Settlement | Two to seven business days | Seconds, straight to your wallet |
| Chargebacks | Disputes and reversals | On-chain transfers are final |
| Getting approved | Application and underwriting | Sign in, publish, share a link |
| Cost | Typically 2.9% + 30¢ per payment | A flat monthly plan |

How it works
From sign-in to first payment in three steps
No contracts to deploy and no crypto engineering to hire for. Turbine runs the on-chain part; you run the business.
- 01
Publish your business
Name it, add a plan for each thing you sell, and connect the wallet that gets paid. You are live before the coffee cools.
- 02
Share one link
Your hosted checkout handles wallet connection, the price in USDC and a single approval. No forms to build, no card fields to secure.
- 03
Hear about every subscriber
Each new subscription is recorded on-chain and lands in your dashboard, your inbox and your webhook endpoint at the same time.
Publish your first business
Takes about five minutes.
For developers
Gate your product with one webhook
Turbine tells your backend the moment someone subscribes. Unlock the feature, mint the API key, open the door.
Every event is signed
Verify the turbine-signature header with your signing secret, check the timestamp, and drop anything you have already seen by its idempotency key.
Nothing gets lost
Delivery is queued and retried. Failed deliveries can be replayed, so a deploy in the wrong minute never costs you a subscriber.
Or skip the hosted flow
Every plan includes API access. Prepare, sign and confirm subscriptions from your own product when the hosted checkout is not enough.

FAQ
Questions, answered
Do my customers need to know anything about crypto?
They need a Solana wallet holding USDC. Checkout connects the wallet, shows the price and asks for one approval. There are no seed phrases, gas settings or bridges on the page.
Where does the money go?
Straight to the wallet you connect when you publish your business. Turbine never holds funds, and there is no payout schedule to wait for.
What do I have to build?
Nothing for the hosted flow. If you want to gate features in your own product, listen for the subscription.created webhook or call the API. Both come with every plan.
How do I know who is still subscribed?
Every subscription is recorded on-chain with its plan and period. The dashboard lists active subscribers and recent payments, and your webhook endpoint hears about every new one.
Can I change my plans later?
Yes. Add plans any time from the dashboard, each with its own price and period, and keep several businesses under one account.
Which tokens and networks are supported?
USDC on Solana today. Prices are set in USDC, so there is no exchange rate to explain.
