Optimism is an Ethereum-based decentralized infrastructure platform that allows for instant transactions and scalable smart contracts.

Optimism is focused on the development of optimistic rollups, which are scaling layers that aggregate transactions above the base Ethereum layer.

Optimism was founded in 2019 by Jinglan Wang, Benjamin Jones, Karl Floersch, and Kevin Ho. The company is headquartered in New York, New York.


Optimism is an Ethereum Layer 2 scaling solution that uses optimistic rollups to achieve far lower fees, far lower latency, and far greater throughput versus Ethereum Layer 1 alone while also providing a world-class developer and user experience.


Optimism is based on Optimistic rollup technology, which has generally been seen as a more near-term viable solution due to some of the cryptographic complexities of ZK rollups that are used by other networks made by startups like StarkWare and Matter Labs.


Optimism has around $5.75 billion TVL currently held on L2 Blockchains. Optimism is approaching a half-billion in TVL, though Offchain Labs’ Arbitrum is closing in on nearly $3 billion as the market leader.


Optimism is backed by Andreessen Horowitz and Paradigm. The company raised $150M in a Series B round on Mar 17, 2022. This brings Optimism's total funding to $178.5M to date. The latest round mints Optimism a unicorn with a valuation of $1.65B post-money.
