What is Optimism?
Optimism is a layer 2 chain, meaning it functions on top of Ethereum mainnet (layer 1). Transactions take place on Optimism, but the data about transactions get posted to mainnet where they are validated. It’s like driving in a less crowded side street while benefiting from the security of a highway.
Optimism is the second-largest Ethereum layer 2 with a total of $313 million locked into its smart contracts, as of this writing, according to Defi Llama. Arbitrum comes first with $1.32 billion.
Synthetix, a derivatives liquidity protocol, is the largest protocol on Optimism, with a total value locked (TVL) of $125 million. Uniswap, a decentralized exchange (DEX), is the second most popular protocol on the chain. As of this writing, there are 35 protocols on Optimism with at least $1,000 locked into their smart contracts.
