Optimism chain
Overview
Optimism (OP Mainnet) is an Ethereum Layer 2 scaling solution that uses optimistic rollup technology to increase transaction throughput and reduce fees while inheriting Ethereum's security. It employs a single sequencer and fraud proofs to settle transactions on Ethereum. The network is governed by the OP token, which is used for voting on protocol upgrades.
Within the DeFi Intel graph, Optimism connects to 204 tracked entities, most strongly to Ether (ETH), Ethereum, Morpho Blue.
