Products

What you can offer on top of Zarban

Three financial products, running on the same contracts and the same API that the public Zarban protocol runs on. Debt and yield are all denominated in ZAR, Zarban's unit of account.

Savings on idle balances

Put your own or your users' unused balances into Zarban's lending pool and earn from the fees borrowers pay. No lock-up period.

Talk to us about this

Deposit and withdraw from any account through the API
Variable rate, paid by borrower fees — not a return we guarantee
Live position and accrued yield, per account

Collateral-backed installment credit

Lend to your users without building the collateral engine, the pricing or the liquidation logic yourself. Collateral locks, and the debt is recorded in ZAR.

Talk to us about this

Ready plans with a collateralisation ratio, annual fee and debt ceiling
Choose the installment count and interval from the available configs
Estimate before you create, then track loan health and repayment

Collateral positions and a shareable link

Open a collateral position against any account. The position id is itself a public link: anyone holding it sees the locked collateral and its live state, with no account and no wallet.

Create from the dashboard or the API, choosing the account and debt amount
A public page carrying your organisation's branding, openable on mobile
Increase or decrease collateral or debt at any time

Each product is enabled per organisation, and the dashboard shows only what that organisation is licensed for. Rates and terms are settled on the first call.

The infrastructure all of it runs on

What every organisation gets from day one, whichever financial products are switched on.

HD wallet service

Accounts and deposit addresses

Programmatically create accounts and generate a dedicated deposit address per user.

Real-time webhooks

Get notified on deposits, withdrawals and account events, with retries and full logs.

Observability and analytics

An operational dashboard with transactions, hot-wallet balances, account and loan charts, and configurable alerts.

Organisation management

Multiple users, owner and admin roles, scoped API keys and a full activity history.

From zero to first deposit

Three steps. No smart contract knowledge required.

Security

Why you can put customer assets on this infrastructure

Audited contracts

Two independent AuditOne audits on the same contracts the public Zarban protocol uses.

Key management

Private keys stay inside the HD service and are never returned in any API response.

Open source

Zarban's contracts are open source, and any technical team can review them before integrating.

Full audit trail

Every sensitive operation is recorded with actor, timestamp and result, reviewable in the dashboard.
