Kite
Crypto payment links and checkout. Customers pay in any token; you're paid in USDC.
Kite gives you payment links and a checkout for crypto. You create a link with a price in dollars, your customer pays it in any token you accept, and the payment settles in USDC. Your systems hear about it through a signed webhook.

Two ways to use it
Hosted Kite
Use Kite's own instances, testnet and mainnet. No server to run; Kite pays you out in USDC.
Run your own server
The server is open source. One Docker image, your chains, settled straight to your own wallet.
Both run the same dashboard, checkout and API, so everything under Payments, Authentication and Integrate applies to either.
