The main objective of this research was to evaluate the moderating effect of financial literacy on the effect of digital wallet adoption on financial behaviour among users in Cameroon. Methods: A quantitative research methodology was utilized in the study, the population of the study was digital transaction users, and a sample size of 389 participants was chosen using a non-probability sampling approach. The data source was primary data; data collection was by self-administered questionnaires and data analysis was using ordinary least square (OLS). The findings indicate that, the use of a digital wallet has a statistically significant positive effect on money management (β = 0.1855, p < 0.05). this implies that an individual’s use digital wallets will lead to an increase in financial behaviour by 0.1855 unit points all things being equal, the finding further shows that, when financial literacy is included, the coefficient for Model (2) becomes much larger, β = 0.4744 (p<0.001) and statistically significant at 1% level of significance. This means that the good link between using a digital wallet and having excellent financial literacy has a stronger effect on financial behaviour. The finding revealed that, Model (2) revealed that financial literacy has a significant positive coefficient β = 0.1933 (p < 0.001). This implies that there is a greater understanding of money as it relates to improved financial behaviour as long as individuals continue to use digital wallets. However, when we include the interaction variable between using a digital wallet and financial literacy, the coefficient for financial literacy drops to β = 0.1040 in Model 3, which is not statistically significant at this level. The finding further demonstrates that, in Model 3, the interaction term between using a digital wallet and financial literacy is positive (β = 0.1652, SE = 0.1706) but statistically not significant. According to the findings, there is no statistically significant evidence that financial literacy moderates the relationship between the use of a digital wallet and financial behaviour. The positive coefficient indicates a likely moderating impact but the large standard error relative to the coefficient means that this moderating effect cannot be statistically demonstrated. Study recommends that, campaigns should educate people not just on how to use digital wallets, but also on how to use them safely. Users should be educated on financial literacy on transaction costs, privacy, fraud protection, account security, saving money and making sensible financial decisions.
