Twitter boss Jack Dorsey has tweeted the Nigerian flag in what local media have interpreted to be support for the Saturday protests against poor governance and the suspension of the microblogging platform.
Mr Dorsey's tweet attracted comments from Nigerians who are using virtual private networks (VPN) to access the app.
Twitter is in discussions with the Nigerian government after it was banned in the country on 5 June.
The ban came after the app deleted President Mohammadu Buhari's tweet but the presidency said the ban was not connected with that action.
Nigerians on Saturday took to the streets to demonstrate over poor governance, lack of democracy and the Twitter ban.
Police fired teargas at the protesters and several were arrested, according to local media.
Saturday's protests were the first since the #EndSARS ones against police brutality that went on for weeks.
