Ethereum-scaling system Optimism delayed its mainnet launch to July after the venture-backed startup’s promise of a debut in March proved to be “overeager,” the project announced Thursday.

  • In a blog post, Optimism, which last month raised $25 million from Andreessen Horowitz and others, admitted the original timeline was unworkable and took many projects by surprise.
  • Rushing its tech salve for raging Ethereum gas fees could have dangerous consequences. “There is a very real risk of” projects getting fraudulently forked by bad actors, the post said. 
  • Optimism called July a “rough estimate” for its mainnet launch. A hacker-ready testnet will debut in late April.
