Crypto API and Tubali Crypto Wallet

Launch a crypto wallet without building one.

Two ways in. Integrate our Crypto API into your own product, or launch the Tubali Crypto Wallet under your brand. Either way, you choose which modules to switch on.

FAQ

Questions people ask

Something else? support@z9pay.com

Is there a sandbox?

Yes. Sandbox keys work against simulated billers, chains and payouts, with the same API shape as production.

How do I go live?

Complete business verification, sign the API agreement, and our compliance team reviews your use case. Most reviews finish within five business days.

Do you send webhooks?

Yes. Every object change triggers a signed webhook. We retry with backoff for 72 hours until your endpoint returns a 2xx.
