In an age where digital currencies and cryptocurrencies backed by powerful high-end security firewall gets routinely hacked by hackers, almost at will, how safe is my e-naira wallet in a Nigerian cyberspace?

It appears that Nigeria do not have a strong enough security apparatus to prevent mass attacks on e-wallets holding e-nairas, especially if the hackers are foreign based. Therefore, as someone mentioned in an earlier comments on a post, that the CBN controls e-wallets and e-naira directly, does it translates that the level of defense will be CBN-caliber?

If the firewall security is outsourced and the company failed to prevent a hacker intrusion, will the CBN accepts the responsibility for the loss and return all my money back being the custodian of my e-wallet?

Does anyone know enough about CBN Policy on e-naira to educate us? Or are there fine prints in the terms and conditions that absolves CBN of any responsibility in the event of a wallet-drain through an hacker attack?
