The global equity market is cautiously opening its doors to blockchain technology, catalysed by the US Securities and Exchange Commission's recent five-year pilot framework permitting tokenised stocks to trade on-chain. For emerging markets, the implications stretch far beyond decentralised finance promises of round-the-clock liquidity.

In Nigeria—where retail smartphone adoption heavily outweighs conventional capital-market engagement—migrating the Nigerian Exchange (NGX) onto high-throughput blockchain rails has become an active infrastructural debate. Yet moving equity from a legacy depository to a public ledger demands reconciling programmable code with strict Nigerian securities law.

Dr Harrison Obiefule, ecosystem lead at Superteam Nigeria, argues that the true challenge is not writing smart contracts but establishing systemic equivalence. The standard crypto pitch for tokenising capital markets leans heavily on continuous trading and instant settlement. In his view, this misdiagnoses institutional readiness. Nigeria's conventional market has already proved its appetite for structural reform, having formally transitioned its equities settlement cycle from T+2 to T+1 in June 2026, meaning trades now settle one business day after execution instead of two. Moving an equity onto a blockchain, however, does not mean it must automatically trade without pause or settle instantaneously.

“Moving a share onto a blockchain does not automatically mean you should make it trade 24/7 or settle instantaneously. You still have to solve liquidity, market-making, corporate actions, price discovery, custody, surveillance, investor protection and the relationship between an on-chain trade and the legally recognised shareholder register,” Obiefule explains.

Market-making desks require downtime for reconciliation, and liquidity fragments when stretched across an uninterrupted schedule. The strategic approach with institutional stakeholders and regulators, he argues, should not be an aggressive demand to replace the established order overnight simply because blockchain is faster. Instead, the real dialogue with institutions must identify which inefficiencies programmable settlement can eliminate without introducing new systemic risks. “That framing makes the transition much more realistic,” he adds.

Regulatory groundwork is already in place

Nigeria has already laid vital regulatory foundations. The Investments and Securities Act 2025 explicitly includes virtual and digital assets within the definition of securities, ending ambiguity over whether tokenised assets fall within the regulatory perimeter. The primary obstacle now is establishing legal and operational equivalence.

“If I own a token representing 0.01% of a Nigerian listed company, the important questions are: What exactly do I legally own?” Obiefule asks. “Is the token itself the security, or is it merely a digital representation of a security held elsewhere? Who appears on the register? Who receives dividends? How are voting rights exercised? What happens during a stock split, rights issue or corporate action? Who has finality when the blockchain record and the conventional market infrastructure disagree?”

Resolving these ambiguities, he argues, requires explicit statutory guidelines covering approved distributed ledger technology infrastructure, custody, settlement finality, and interoperability with the Central Securities Clearing System (CSCS), Nigeria's central depository for equities traded on the NGX. While the SEC's Accelerated Regulatory Incubation Program (ARIP) provides a vital controlled environment for regulators to observe these models, tokenisation must eventually graduate into standard capital-market infrastructure.

Architecting an on-chain equity market, he stresses, is not a binary choice between old and new but an evolutionary continuum. In the near term, the most viable route involves a regulated one-to-one custodial model: the underlying NGX-listed security sits undisturbed inside existing depository vaults while an authorised entity issues a verifiable on-chain representation against it. This wrapped mechanism unlocks programmable distribution without requiring immediate legislative rewrites of the national corporate governance code.

The long-term objective, however, remains native on-chain issuance. “Imagine a future Nigerian IPO where the issuer, NGX, SEC, CSCS, registrars and other regulated participants recognise an authorised on-chain representation from issuance,” Obiefule says. At that stage, the blockchain becomes part of the capital-market infrastructure itself.

A cautious, crawl-before-you-run pilot

To prove the concept, Obiefule advocates a deliberate, crawl-before-you-run approach. “I think we crawl before we run: regulated representations first, native issuance eventually,” he notes. Rather than attempting to migrate the broader exchange in a single sweep, a controlled deployment should target a select basket of highly liquid, large-cap blue-chip equities with established institutional participation and mature registrar frameworks.

Beginning with assets that already enjoy robust price discovery, he argues, equips regulators and market operators with an authoritative off-chain benchmark to evaluate settlement, custodial safety, reconciliation, and dividend delivery end-to-end.

The hard part is not the ledger

On technical feasibility, the base ledger is readily available. High-performance blockchains such as Solana offer high throughput, low network fees, and predictable finality. The genuine architectural friction, Obiefule says, sits entirely at the gateway where the blockchain touches the regulated financial system.

Deploying a fully compliant on-chain exchange in Nigeria would demand enterprise-grade custody, licenced tokenisation protocols, compliant fiat and stablecoin payment rails, deep institutional market-maker liquidity, verified identity or know-your-customer (KYC) layers, and robust oracle infrastructure to handle corporate actions. Most importantly, it requires an airtight legal bridge guaranteeing that the state of the blockchain matches the official corporate share register.

“Tokenising a stock is technically easy. Building an entire regulated market around that token is the difficult part,” Obiefule states.

Building that ecosystem also exposes a pronounced human capital challenge. While Nigeria boasts one of the most prolific Web3 developer communities globally, shipping consumer decentralised applications does not prepare an engineer to manage market-clearinghouse software. The primary bottleneck, he notes, is an acute shortage of talent standing at the intersection of capital-market microstructure and smart-contract engineering. Securing trillions of Naira in equity tokenisation demands expertise in clearing, key management, distributed consensus, settlement mechanics, formal verification, and rigorous auditing. Bridging that divide will require structured partnerships between Web3 developer communities and legacy exchange operators.

Stablecoins ease the rails, not currency risk

Tokenisation is frequently pitched as a bypass for foreign exchange bottlenecks, but Obiefule urges caution against viewing it as a total solution. A diaspora investor could fund an account with a regulated dollar stablecoin to acquire a tokenised Nigerian security, significantly reducing settlement friction and geographic barriers. However, if the underlying equity is denominated in Naira, the foreign investor retains currency exposure.

“Stablecoins can create a much more efficient rail for capital formation and settlement,” he explains. “They do not magically eliminate currency risk or macroeconomic constraints.”

Fractionalisation as the near-term prize

Where tokenisation does offer transformative potential is domestic retail access through fractionalisation. For the everyday investor in Lagos, continuous trading is secondary to lowering economic barriers to entry.

Fractionalisation permits retail savers to allocate micro-capital into high-performing, expensive equities that were previously out of reach. It also makes portfolios programmable, paving the way for automated recurring investments, indexation, and borrowing mechanisms in which tokenised shares serve as collateral.

Ultimately, this expands distribution: compliant tokenised shares can reach users through everyday consumer fintech applications, bypassing traditional, fragmented stockbroking portals—a consequential shift in a country where smartphone adoption already runs well ahead of conventional capital-market participation.

Obiefule points to Superteam Nigeria's recent initiatives, including the Dangote IPO campaign and Solana-integrated product pilots, as early glimpses into this convergence. Yet he is careful to draw a firm boundary: accessing a traditional asset through a Web3-integrated interface is not the same as having the asset natively settled on a public blockchain. That boundary also frames what to watch as the debate matures: whether regulated representations of existing shares give way to native on-chain issuance, and whether the statutory guidelines underpinning legal equivalence move from incubation programmes into standing capital-market law.
