Cortado Testnet Release

Espresso Sequencer testnet 3 (Cortado)—September 2023
In September 2023, we released the Cortado release of the Espresso Sequencer.
In the next couple weeks, we will also be deploying a public Cortado testnet. Instructions for interacting with this testnet can be found here.
The primary highlight of the Cortado release is the integration of a second rollup stack with the Espresso Sequencer: the OP Stack. This integration is a direct result of the work that Espresso Systems completed in developing a leader election interface for the OP Stack, for which Espresso was awarded an Optimism RFP in July 2023. Details on the OP Stack integration can be found here.
