The Exactly Protocol, which backs up the credit for the Exa App and Exa Card movements, works on Optimism.

The Optimism Network is a layer 2 scaling solution for Ethereum that aims to enhance the scalability and affordability of Ethereum transactions. It uses a technology known as Optimistic Rollups, allowing faster and more cost-effective transactions than can be processed directly on the Ethereum mainnet. The key idea behind Optimistic Rollups is that transactions are "rolled up" and processed off-chain, and only the resulting state is submitted to the Ethereum blockchain. This significantly reduces the amount of data that must be stored and processed on the Ethereum mainnet, leading to lower fees and faster transaction times for users.
