About Optimism
Optimism is a network of chains called the Superchain, built on the open-source OP Stack. OP Mainnet was the first chain, with several others now operating on the OP Stack architecture, including Base (by Coinbase), Unichain (by Uniswap), Ink (by Kraken), and World Chain (by Worldcoin). The OP Stack serves as a framework for Ethereum Layer 2 chains and supports significant L2 activity. Every OP Chain in the Superchain contributes back to the Optimism Collective and all chains follow a standardized revenue-sharing model: the greater of 2.5% of total chain revenue or 15% of onchain profit (defined as fees minus L1 gas costs) is paid back to the Optimism. By aligning economic incentives across many chains, Optimism aims to transform Ethereum scaling into a sustainable flywheel by delivering fast, low-cost transactions while reinvesting in the future of the ecosystem. OP holders participate in governance to shape protocol upgrades, funding decisions, and more
About Arbitrum
ARB is the utility token of Arbitrum, an Ethereum layer-2 network. ARB functions as the governance token of the Arbitrum DAO, as holders may create and vote on governance proposals.
