Celo

Celo is a Layer 2 blockchain built on top of Ethereum, designed to make decentralized applications accessible to people around the world, particularly those using mobile devices. It addresses the problems of high transaction costs and technical complexity that have historically limited blockchain adoption among everyday users. The project positions itself as infrastructure for developers building products intended to reach large, global audiences.

Celo operates as part of the Optimism Superchain ecosystem, settling transactions on Ethereum while processing activity on its own chain. It uses a Proof of Stake consensus mechanism, meaning validators stake CELO tokens to participate in producing and confirming blocks. The CELO token is used to pay transaction fees on the network, and the chain processes blocks extremely quickly, with a recorded block time of effectively zero minutes, meaning blocks are produced in seconds.

Fees on Celo are paid by users submitting transactions to the network; the median transaction fee recorded on 2026-10-19 was 0.003119 USD, reflecting the network's emphasis on low costs. Over the trailing 12 months the network collected 558389 USD in fees, and over the trailing 30 days it collected 83815 USD, with fee activity annualizing to approximately 1019749 USD based on that 30-day window. Notably, the protocol records zero revenue across the 24-hour, 30-day, and 12-month periods shown, meaning none of the fees collected flow to the protocol or a treasury as defined by this site's methodology — all fee-based revenue measures here reflect that absence.
