By Junaid Ijaya and Femi Babatunde

In the ever-evolving space of digital finance, where the currency of choice fluctuates as swiftly as the internet’s whims, the Ronin Network Hack of 2022 served as a stark reminder of the high stakes involved. Picture this: a playground for the modern gamer and financier, where fortunes in the form of digital tokens swing with every click—a universe where even virtual Axies (charming digital creatures) are worth millions. But amidst this digital gold rush, a nefarious plot unfolded, one that would see over $625 million vanish into the ether.

This was not just any heist. It was a breach that shook the very foundations of the blockchain gaming and decentralized finance (DeFi) sectors, highlighting vulnerabilities that went far beyond a mere loss of assets. The Ronin Network, designed as a fortress guarding the bustling economy of Axie Infinity, fell victim to an assault that was as sophisticated as it was devastating. This case study explores the intricate details of the attack, unravelling the layers of security that were bypassed and the subsequent shockwaves that rippled through the digital domain. Here, we explore why this incident stands out in the crowded field of recent cybersecurity breaches, serving as a critical lesson for stakeholders across the fintech landscape.

2.0 Understanding the Ronin Network

Have you ever been curious about what’s behind the surge of new gaming and financial platforms that are more than just fun but also potentially profitable? Meet blockchain technology, specifically Ethereum and its customized sidechain, Ronin, which have been game changers in this field of financial gamification.

Ethereum expands on the basic concept of blockchain, which traditionally supported transactions like those seen in Bitcoin. It introduces a platform where developers can create decentralized applications (dApps) through smart contracts. These are programs that automate agreements and transactions directly on the blockchain, making operations not only more efficient but also secure and transparent.

One of the most innovative applications of this technology is the Ronin Network, tailored specifically for Axie Infinity—a game that has become a standard-bearer for the “Play-to-Earn” model. In Axie Infinity, players engage in more than just gameplay; they participate in a mini-economy, breeding, raising, and battling creatures called Axies to earn cryptocurrency rewards. This setup was ideal for Ethereum’s capabilities, but it highlighted some limitations in terms of transaction costs and speeds. Ronin was developed to address these issues, providing a sidechain solution that supports quicker and cheaper transactions while maintaining robust security.

What Axie Infinity does is showcase how blockchain can bridge entertainment with real economic incentives, turning gaming into a platform not only for enjoyment but also for financial gains. This paradigm shift not only alters how games are played but also introduces a new way for players to engage in and understand economic systems in a digital era.

3.0 Details of the hack

When $625 million disappears from a network designed to be ultra-secure, it makes you wonder: How could this happen? Let’s peel back the layers of the Ronin Network hack to understand the technical nuances and the security lapses that allowed this dramatic heist to unfold.

The Ronin Network, an Ethereum sidechain developed to support the bustling digital economy of Axie Infinity, was breached on March 23, 2022. The attackers used a method known as “social engineering” to initiate the breach. They targeted the network’s validators, who are responsible for confirming transactions on the blockchain. By exploiting the trust and verification mechanisms between these validators, the hackers managed to execute their plan.

But how exactly did they get in? The breach was primarily facilitated through the compromise of private keys. In blockchain technology, private keys are akin to the most secure passwords. Possessing them essentially grants full control over the associated resources. In the case of Ronin, the attackers obtained access to five out of the nine validator nodes. According to reports, this was enough to form a consensus group, allowing them to authorize fraudulent transactions (Sky Mavis, 2022).

Here’s where it gets interesting: the attackers specifically targeted a backdoor in the gas-free RPC node, which was initially instituted to facilitate free transactions for convenience. Once they accessed the RPC node, they forged fake withdrawals. It’s like finding a spare key under the mat; once inside, they had free reign.

This method of attack raises a critical question: In an age where digital fortresses are supposed to be impregnable, how could such a simple oversight occur? The truth is, even the most secure networks can have vulnerabilities that are overlooked until exploited. The Ronin hack underscores the need for rigorous security protocols at every layer of network operations, especially on decentralized platforms where multiple validators are involved. It also highlights the paradox of blockchain security: the balance between user convenience and stringent security measures is a tightrope walk.

In the aftermath of the Ronin Network heist, the spotlight wasn’t just on the staggering $625 million that evaporated but also on the glaring security vulnerabilities it revealed. So, what were these weak spots, and why were they so critical in the scheme of this digital break-in?

First, let’s talk about the over-reliance on a limited number of validators. Ronin operates on a smaller consensus model with only nine validators—a stark contrast to Ethereum’s thousands. While this structure allows for faster and cheaper transactions, it inherently reduces the network’s resistance to certain types of attacks. Essentially, gaining control over a majority of these validators, as the hackers did, is akin to holding the master key to the network. It’s like if only nine people had the code to the city’s main vault; compromise a few, and you’re in.

Moreover, the use of a “gas-free RPC node” exposed a significant security flaw. Designed to ease transaction processes, this node became the hackers’ golden gate. It was supposed to be a convenient feature, but who thought convenience could cost so much? This feature was exploited to initiate unauthorized transactions without triggering standard security protocols. This kind of vulnerability begs the question: In trying to streamline and simplify, are we inadvertently lowering the drawbridge for attackers?

Another critical point was the insufficient security measures around the authentication processes for these validators. The fact that social engineering could be used so effectively to compromise key components of the network’s security architecture suggests a lapse in both technical safeguards and operational security training. It’s a classic case of underestimating the human element in cybersecurity. Could stronger, multifactor authentication and more rigorous security training for all personnel involved have thwarted the attackers?

Reflecting on these vulnerabilities exposes a broader issue in the blockchain space. As networks like Ronin seek to balance performance with decentralization, how much risk are they willing to accept? And more importantly, how can these networks bolster their defences without compromising the principles of decentralization that make blockchain technology so revolutionary? These are not just rhetorical questions but real challenges that need addressing if blockchain networks are to be trusted as the financial infrastructure of the future. Where do you think—where should the line be drawn between convenience and security in blockchain architectures?

MTN Fintech Targets Credit Market With Direct Lending Plans

The financial technology arm of MTN is mulling a direct shift into lending after bringing on its parent company, MTN Group, as a major investor to help cushion against losses that have plagued the business.

According to MTN Group Fintech chief executive, Mr Serigne Dioum, the company wants to move beyond helping customers access loans through partners.

He said in markets where regulators allow it, MTN wants to lend directly and use its own balance sheet.

“We’ve expanded access to credit for more people, but we also want to move further up the lending value chain,” Mr Dioum told investors at the company’s capital markets day.

“Where appropriate, we will seek licences that allow us not only to facilitate loans but also to lend directly to customers and deploy our own balance sheet.”

This development is expected to create a shift in its current fintech model which provides financial services, including deposits, payments, transfers and digital wallets to individuals and small businesses via digital and mobile‑based platforms.

The company has applied for Payment Solution Service Provider and Payment Terminal Service Provider licences through MoMo PSB, its Nigerian fintech subsidiary. If approved, the licences would allow MTN to handle more payment processing, build merchant payment tools, deploy and manage POS terminals, and reduce its dependence on third-party processors.

Despite the opportunities present in the credit market, direct lending could give MTN a larger share of revenue, but it would also expose the company to credit risk, regulation and tougher competition with banks and digital lenders.

Mr Dioum said only about 4 per cent to 5 per cent of adults have access to formal credit across the African continent. In Nigeria, the funding problem is especially severe.

A 2025 report by the National Credit Guarantee Company said nearly 80 per cent of Nigerian MSMEs lack access to formal credit, while Stears has estimated the country’s MSME financing gap at about $236 billion.

For traders, small shop owners, transport operators and households, access to small loans can determine whether they restock inventory, pay suppliers, cover emergencies or expand a business.

In April, MTN Nigeria announced that its parent firm, based in South Africa, would acquire a 60 per cent stake in MoMo Payment Service Bank Limited (MoMo PSB) and Y’ello Digital Financial Services (YDFS) Limited.

The fintech units are currently loss-making, and this move will help MTN Nigeria to reduce financial risk and share future losses and investment burden. However, it will still keep a significant minority stake (40 per cent).
