The eNaira speed-wallet app meant for individuals had, as at 4 pm, seen more than 5,000 downloads while the eNaira speed merchant wallet had seen close to 1,000 downloads.
According to the regulatory and issuance guidelines, banks will automatically be onboarded by the CBN while merchants will be onboarded once they download the app and individuals will have to onboard by themselves.
The guideline revealed that there would be different wallets for different stakeholders.
"The eNaira stock wallet belongs solely to the CBN and it shall warehouse all minted eNaira," the guideline stated.
It said that financial institutions were expected to maintain one treasury eNaira wallet to warehouse eNaira received from the CBN eNaira stock wallet.
"Financial Institutions (FI) may create eNaira sub-treasury wallets for branches tied to it and fund them from its single eNaira treasury wallet with the CBN and FI may create eNaira branch sub-wallets for its branches.
"The eNaira branch subwallet shall be funded from the treasury eNaira wallet.
"eNaira Merchant speed wallets shall be used solely for receiving and making eNaira payments for goods and services. eNaira speed wallets shall be available for end users to transact on the eNaira platform."
To ensure security of funds, the eNaira is expected to have two-factor authentication and other measures.
Meanwhile, daily transaction limits for Tier 0, which is just phone number without verified National Identity Number, was set at N20,000 with a balance limit of N120,000.
Tier 1 category, which has a verified number has a N50,000 transaction limit and N300,000 balance limit.
Tier 2 and Tier 3 categories have daily transaction limits of N200,000 and N1 million as well as a N500,000 and N5 million balance limits, respectively, while merchants have no limit.
According to a circular signed by Mr Chibuzo Efobi, the CBN director Financial Policy and Regulation Department, the eNaira will compliment cash as a less costly, more efficient, generally acceptable safe, and trusted means of payment and store of value.
"Additionally, it will improve monetary policy effectiveness, enhance government's capacity to deploy targeted social interventions, provide alternative less costly channel for collection of government revenue and boost remittances through formal channels.
"The guidelines seek to provide simplicity in the operation of the eNaira, encourage general acceptability and use, promote low cost of transactions, drive financial inclusion while minimizing inherent risks of disintermediation or any negative impact on the financial system," it reads in part.
