According to Odaily Planet Daily, in response to Ethereum co-founder Vitalik’s high praise for Celo, the chain detective ZachXBT commented that he has not seen a real user of Celo so far, calling it a ‘ghost chain’ integrated into the Optimism stack.
In addition, ZachXBT agrees with the view mentioned in the comments that Metal DAO and Celo use the super chain mechanism to obtain OP ecological incentives.
