South Africa’s ZARU Launches Self-Service Minting and Redemption for Institutions

South Africa’s rand-backed stablecoin ZARU has taken another step toward becoming institutional payment infrastructure, with qualified businesses now able to mint and redeem the token through a new self-service platform.

BlockTower, the regulated South African company that issues ZARU, launched its Issuance Platform in October 2026. Instead of arranging every issuance or redemption manually with the BlockTower team, approved institutional customers can now deposit rand, receive newly minted ZARU in an approved wallet and track the process through an online portal.

The important word here is institutional.

This is not a new app where anyone can send R100 and mint 100 ZARU. Direct issuance and redemption remains limited to verified institutional clients. The change is that those businesses can now manage the process themselves once they have completed BlockTower’s onboarding requirements.

For ZARU, that may sound like a small operational upgrade. In practice, it moves the stablecoin closer to functioning like infrastructure that payment companies, exchanges and treasury teams can actually use repeatedly.

First, What Is ZARU?

ZARU is a South African rand-backed stablecoin designed to maintain a value of one ZARU for one South African rand.

Unlike dollar stablecoins such as USDT and USDC, ZARU is denominated in rand. That means a business can move value on-chain without first converting its rand exposure into US dollars.

According to the ZAR Universal white paper, each ZARU is backed by rand-denominated reserves. Holders can transfer ZARU between compatible blockchain wallets, while eligible institutional customers can redeem the token back into rand at a 1:1 ratio subject to identity and compliance checks.

BlockTower says reserves are held in South Africa and independently attested each month by Moore Johannesburg. The company is also an authorised South African financial services provider under FSP 55172.

In simple terms, ZARU is trying to make the rand behave more like an internet-native asset.

The money remains denominated in rand. What changes is how it can move.

What Has Actually Changed?

Institutional customers could already mint and redeem ZARU directly under the stablecoin’s existing framework.

What is new is the self-service process.

Previously, institutions had to coordinate individual transactions with BlockTower. According to Luno, one of ZARU’s founding partners, minting and redemption involved more manual coordination, including email communication with the issuer. The new portal brings those activities into one interface.

An approved institution can now log in, see its verified bank accounts and wallets, initiate transactions, monitor their status and maintain an exportable audit trail.

That is the difference between saying a stablecoin can be issued institutionally and giving a finance team a tool it can realistically use as part of its normal operations.

How Does Minting ZARU Work?

Suppose a South African payments company wants R2 million worth of ZARU for merchant settlements.

After completing BlockTower’s onboarding process, the company receives its own payment reference and has an approved blockchain wallet connected to its account.

The business transfers R2 million to BlockTower’s collection account using that reference. Once the payment arrives and is matched, 2 million ZARU can be minted and sent to the approved wallet.

BlockTower’s Issuance Platform shows the transaction progressing from processing to completion, allowing the institution to track when the rand was received, when it was matched to its account and when the ZARU was issued.

The institution does not need to email someone asking whether the mint has been completed.

It can see the process itself.

And How Does Redemption Work?

Redemption is essentially the process in reverse.

An eligible institution sends ZARU back through the platform. Once the tokens are received and processed, the equivalent amount of rand is paid into the organisation’s verified bank account.

That redemption mechanism is central to how a fully reserved stablecoin attempts to maintain its peg.

If one ZARU represents one rand, institutional participants need a reliable way to move between the digital token and actual rand.

The ZARU white paper states that eligible holders have a right to redeem ZARU at a 1:1 ratio, subject to the platform’s verification requirements and terms.

When ZARU is redeemed, the corresponding tokens are removed from circulation rather than remaining permanently in the market.

Why Does Self-Service Minting Matter?

Imagine a payment company that settles millions of rand every day.

If it uses ZARU as part of its payment infrastructure, it may need to increase its on-chain balance when transaction volumes rise and convert ZARU back into rand when liquidity is no longer needed.

Doing that occasionally through email may be manageable.

Doing it every day at institutional scale is another matter.

The new platform gives approved companies a clearer operational process for moving money between their bank accounts and blockchain wallets. BlockTower says customers can see balances, transaction histories, pending mints, completed redemptions and security activity in one place.

That sounds less exciting than launching a new token.

But financial infrastructure often becomes useful precisely when it becomes boring enough for finance departments to use routinely.

The Platform Is Aimed at Businesses Moving Large Amounts of Rand

BlockTower is not positioning the portal as a retail crypto product.

The company says it is designed for organisations such as payment service providers, exchanges, brokers, treasury teams and other institutions that need to move rand at volume.

A payment company, for example, could hold ZARU for merchant settlement and mint additional tokens when its balance runs low.

An exchange could maintain ZARU liquidity for customers and redeem excess tokens back into rand.

A corporate treasury could move part of its rand liquidity on-chain while keeping a record of every mint and redemption for accounting and audit purposes.

These are less glamorous use cases than watching a token price go up 500%.

They are also much closer to what stablecoins were originally built to do: move money.

Retail Users Cannot Mint ZARU Directly Through the Platform

This distinction is worth repeating because the term “self-service” could easily create the wrong impression.

The BlockTower portal is not open to ordinary retail customers.

The ZARU white paper says direct minting and redemption is available only to verified institutional clients after they complete BlockTower’s identity, anti-money-laundering and onboarding requirements. Retail users instead access ZARU through approved partners.

BlockTower’s onboarding process also requires organisations to complete know-your-business checks and connect verified bank accounts and approved wallets before they can begin minting.

So if you are an individual holding ZARU, you do not simply send rand to BlockTower and create new tokens yourself.

The institutional layer handles primary issuance.

Retail and other market participants generally access the token through distribution and trading partners.

ZARU Is Already Trading Against USDT and USDC

ZARU has also been building liquidity outside the issuance system.

Luno introduced ZARU/USDT and ZARU/USDC trading pairs in August 2026, creating a direct route between the rand-backed stablecoin and two of the largest dollar-backed stablecoins. The pairs are available to eligible Luno customers in South Africa, Kenya, Nigeria and Uganda.

That matters because issuing a stablecoin is only part of the challenge.

People also need places to buy it, sell it and exchange it for other forms of money.

Previously, someone moving between a dollar stablecoin and rand exposure might have needed to convert back into conventional rand first. ZARU’s stablecoin pairs create an on-chain route between dollar and rand-denominated digital value.

For businesses operating across African markets, that could eventually make ZARU useful beyond South Africa itself.

ZARU Has Also Expanded to Arc

ZARU has been expanding its blockchain presence as well.

On September 16, the project announced that ZARU had gone live on Arc, the Layer 1 network designed for financial applications and real-time money movement.

The idea is to connect rand-denominated liquidity with a broader on-chain financial ecosystem where stablecoins and other tokenised assets can settle continuously.

However, there is an important difference between ZARU being live on a blockchain and the new issuance portal supporting that blockchain.

For now, BlockTower says direct minting and redemption through the new portal is available on Solana. Portal support for Arc is listed as coming later.

The company also plans to support more networks over time.

An API Is Coming Next

The web portal may not be the final destination.

BlockTower says it is developing an issuance API that will allow institutions to mint and redeem ZARU directly from their own systems.

That could be especially important for payment companies.

Imagine a fintech processing thousands of merchant settlements. Instead of an employee logging into a portal whenever the company needs more ZARU, its treasury system could eventually initiate the process automatically according to predefined rules.

That is where stablecoin infrastructure starts to become less like a crypto trading product and more like a financial rail.

BlockTower has not announced a firm launch date for the API.

ZARU Is Not a Bank Deposit

There is another distinction beginners should understand.

Holding ZARU is not the same as keeping rand in a normal bank account.

The ZARU white paper says the token does not represent equity in BlockTower, does not provide voting rights and does not automatically earn interest or yield. It is designed primarily as a payment and settlement instrument.

BlockTower also warns that stablecoins are not legal tender or guaranteed and that digital assets involve risk.

The 1:1 reserve structure is intended to support ZARU’s value against the rand, but users should not confuse that with a guarantee that every possible operational, technological or regulatory risk has disappeared.

Stable does not mean risk-free.

Why Build a Rand Stablecoin When USDT Already Exists?

This is one of the more interesting questions around ZARU.

USDT and USDC already dominate the global stablecoin market. So why would South African businesses need another stablecoin?

Currency exposure is one answer.

If a South African company earns and spends primarily in rand, moving money into USDT means moving into a US dollar-denominated asset. The business may then face an additional foreign-exchange step when it wants rand again.

ZARU keeps the unit of account in rand.

One ZARU is intended to represent one rand, which makes it potentially more natural for local payments, accounting, treasury management and settlement between businesses already operating in South Africa’s currency.

Dollar stablecoins and rand stablecoins therefore do not necessarily have to compete for exactly the same purpose.

One can move dollars on-chain.

The other can move rand.

This Is Really a Story About Bringing the Rand On-Chain

It is easy to describe ZARU simply as another cryptocurrency.

That misses the bigger idea.

The project is attempting to create a digital version of rand liquidity that can operate on blockchain infrastructure while remaining connected to South Africa’s traditional financial system.

An institution deposits rand through a bank.

ZARU appears in a blockchain wallet.

The token can then move on-chain.

When the institution wants conventional rand again, it can redeem the token and receive money back into its verified bank account.

The new self-service platform makes that bridge between the two systems easier to use.

That may matter more than the token itself.

South Africa Is Becoming an Interesting Stablecoin Market

ZARU’s expansion is happening alongside a broader shift in South Africa’s digital-asset industry.

Banks, exchanges, fintech companies and payment providers are increasingly experimenting with ways to connect blockchain-based money with established financial services.

ZARU itself already has relationships with companies including Luno and other institutional market participants. Its USDT and USDC trading pairs have extended access into several African markets, while the Arc deployment provides another route into global on-chain liquidity.

The challenge now is not simply issuing tokens.

It is creating enough liquidity, distribution, regulation and real-world usage for those tokens to become useful financial infrastructure.

A self-service issuance system addresses one piece of that puzzle.
