Receive payments

Receive payments in Karbo. It's quick, simple and profitable. You increase the value of your Karbo by very accepting it at your store.

REQUEST PAYMENT

It's safe

Only you got the keys

Secret key to your wallet is generated in your browser and never sent to our servers, that's why it's impossible to steal your Karbo from our servers — all we can do is tracking your incoming payments.

Be your own bank!

Just keep your secret key secret in a safe place.

Use it in your wallet

Import your secret key to your wallet — that's the only way to spend your Karbo.

What's the catch?

Convenience comes at the cost of privacy

You share view key of your wallet with us so we can track payments for you.
Because view key is common and known to others, it's possible to expose your incoming transactions.
However they won't know your customer's address or what you did with those funds later.
That's all. We made free gateway and don't collect fees because we need you.
