Crypto unicorn Optimism received an additional $150 million? The Optimism team, which is developing a layer 2 solution for the Ethereum blockchain, has raised another $150 million in Series B. The companies participating in this funding round estimated that the project was valued at $1.65 billion. The main investors this time were a16z and Paradigm. Interest in this project is easy to explain. The company has a working product that, in a year of mainnet existence, allowed users of this add-on on the Ethereum blockchain to save $1 billion in cheap fees. After over a year on mainnet, our milestones keep adding up: $1B in gas fees saved for users, thousands of smart contracts deployed, three separate forks... And now: funds raised to the tune of $150M, giving us runway to keep shipping rain or shine.https://t.co/pBC2jmXtnh — Optimism 🔴✨ (@optimismPBC) March 17, 2022 Due to its popularity in the L2Beat TOP, this zoom level 2 solution ranks fourth.
