Products
Three products every fintech app needs
All three run on the same infrastructure that handles your accounts and transactions, and all three are available from the dashboard and the API.
Savings
Put your organisation's idle balance, such as the rial you hold for settlement, into Zarban's lending pool and earn on it. You can also offer the same savings straight to your own users.
Request a demo45% a year, accrued second by second
Offer your users a fixed rate and keep the spread over the pool rate as revenue
Live balance and accrued yield for every account
Crypto-backed loans
Lend to your users without writing the collateral, pricing or liquidation engine yourself.
Request a demoReady plans with a set collateral ratio, annual fee and debt ceiling
Choose the installment count and interval from the available configurations
Estimate terms before the loan is created, then track collateral health and repayment
Collateral certificate
Create a certificate and get a link back. Whoever opens it sees, with no sign-up, how much collateral is locked and its live state. If you run your own lending, let Zarban hold the collateral while you manage the debt and installments.
Request a demoCreate from the dashboard or the API, with a public page carrying your organisation's brand
Your user deposits collateral on that page and a webhook tells you the moment it locks
Zarban holds the collateral and handles liquidation if it is ever needed
Each product is switched on for your organisation individually: start with the one you need today and add the rest later. The dashboard shows exactly the products you have active.
What you get
Every organisation on Zarban has all of this from day one, whichever financial products are switched on.

Dedicated accounts and deposit addresses
Create an account and a dedicated deposit address for every user.

Receive deposit, withdrawal and account status events in real time.
Operations dashboard

Multi-user management
Multiple users with different access levels, matched to how your organisation works.
From zero to first deposit

Security
How we keep it secure
Audited contracts
Zarban Business runs on the same contracts as the public Zarban protocol, audited by AuditOne.
Custodial key management
Holding the keys, and keeping them safe, is our job. Private keys never leave the custody service.
Open source
Zarban's smart contracts are open source, so your technical team can review them before signing anything.
Full history
Zarban records every sensitive operation with user, time and result, and you can review it in the dashboard.

Launch crypto deposits and withdrawals without building the infrastructure from scratch.
Fintech and financial apps
