Context-Aware Pre-Deployment Evaluation of AI Systems: A Regulatory Framework for Nigerian Fintech

Commercial large language models are increasingly deployed across African fintech infrastructure for fraud detection and customer communication, yet no Nigerian or African continental regulatory instrument specifies what pre-deployment evaluation such systems must undergo before procurement. This paper reviews African fintech AI governance across global, continental, and Nigerian instruments, and shows that safety is affirmed as a principle while pre-deployment evaluation is operationally unspecified. Generic safety benchmarks cannot surface the failure modes most relevant to this domain, since none contain Nigerian institutional content or test for false positive misclassification of legitimate financial communications. These claims are demonstrated using SafeAlert, a purpose-built evaluation kit applied to six commercial models across three system prompt conditions. Results show that models resisting generic harmful content requests still produce complete fraud scripts under specific framing, and that several models misclassify most legitimate Nigerian bank communications as suspicious or fraudulent, a failure invisible to standard safety evaluation. The paper concludes with a regulatory framework proposing pre-deployment evaluation requirements for the CBN, NITDA, SEC, and the AU, arguing that the identified gap reflects an absence of regulatory specification, not a shortage of technical or financial resources.

Nigeria's Digital Sovereignty: Analysis of Cybersecurity Legislation, Policies, and Strategies

This paper examines Nigeria's pursuit of digital sovereignty through two core instruments: the Cybercrimes (Prohibition, Prevention, etc.) Act and the National Cybersecurity Policy and Strategy (NCPS). Despite recent reforms, it remains unclear whether these frameworks effectively secure Nigeria's digital domain and advance its digital sovereignty amid escalating cross-border cyber threats. Using a multi-method, triangulated qualitative design that combines document analysis, secondary analysis of existing studies, expert insights, and direct observation of cybersecurity developments, the paper assesses how these instruments operate in practice. The Cybercrimes Act (2015, amended 2024) and NCPS (2015, revised 2021) have strengthened Nigeria's commitments to tackling cybercrime, regulating digital activities, and protecting critical infrastructure. Yet persistent gaps remain, including legislative ambiguities, weak enforcement, uneven threat prioritization, limited institutional coordination, and loss of skilled professionals. The paper argues that achieving digital sovereignty will require stronger implementation, sustainable resourcing, workforce retention, and clearer accountability mechanisms to translate policy ambition into tangible and durable security outcomes.
