Wu said that in response to Ethereum co-founder Vitalik's praise for Celo, Chain Detective ZachXBT commented: "I haven't seen a real user of Celo so far. This is a 'ghost chain' integrated into the Optimism stack." In addition, he agreed with the views mentioned in the comments that Metal DAO and Celo use super chain mechanisms to obtain OP ecological incentives. Vitalik previously said: "Improving the accessibility of global basic payments and financial services has always been one of the key ways Ethereum benefits the world. I am glad to see Celo gaining attention."
