The Kovan testnet has been deprecated by the Ethereum community, with only two validators remaining. To avoid disruptions on a network that is no longer actively maintained, we’ve started the process of migrating our testnet from Optimism Kovan to Optimism Goerli. As mainnet changes, Optimism Kovan is going to
Bedrock is the cheapest, fastest, and most advanced rollup architecture. Ever. Optimism has always tried to stay on the cutting edge of rollup architecture. Last year, we introduced the concept of EVM Equivalence, the rollup design pattern of using existing mainnet Ethereum clients (like Geth) as the foundation for L2.
Solidity devs: meet Smock v2. The Solidity mocking library. A collaboration between Optimism and the fantastic team over at DeFi Wonderland. Smart contract testing has historically been… hard? If not hard, then just confusing. Way back in the early days of Solidity the best way to test a contract was
