Omni is a high-performance layer 1 blockchain that aims to connect all rollups and eliminate liquidity fragmentation among layer 2 networks. Omni allows developers to create cross-rollup applications and expand existing applications across all rollups. OMNI tokens are used to pay for Omni EVM gas fees and function as the universal gas resource for cross-rollup communications. OMNI tokens can also be staked to secure the network. Coinbase only supports OMNI as an Ethereum ERC-20 token.

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
