I been never notice this news on my okex news feed, I still dey conduct p2p trade on my okex app and no restrictions, I just made successful p2p recently on the 4th of this month maybe the news never dey effective.
You did not make this transaction on the 4th of this month, take a good look at the order time, it was on the 24th of last month, and at that time trading in Naira was still available on OKX centralized exchange, they delisted trading in Naira on the 3rd of this month.
