Introduction
The three most well known Optimistic Rollups are Optimism, Arbitrum and Metis. But there is a new one in town, currently in testnet.
It might be a good idea to interact with the testnet and be ready when they launch on mainnet.
Just saying.
Last time we said to use Optimism, everybody got a fat airdrop.
“Those who do not learn history are doomed to repeat it”. -George Santayana
So if you missed the Optimism airdrop, you know what to do.
