Get started with Smart Rollups

Smart Rollups are the backbone of Tezos’ scaling strategy and hence instrumental in reaching our goal of 1 million transactions per second in 2023.

But Smart Rollups are much more than that. They enable entirely news way of building decentralized applications on Tezos, using any programming language that compiles to WASM, such as Rust, C/C++, Go and Python.

The scalability and flexibility makes Smart Rollups the perfect solution for any organization looking for a future-proof blockchain solution. Don’t hesitate to reach out to Nomadic Labs’ adoption and support team if you have questions regarding this.

For builders and tinkerers we recommend the Tezos Developer Slack or the Tezos Discord if you need help getting started, as well as these community resources:

We are excited to be part of this major step in Tezos’ evolution, and look forward to seeing Smart Rollups deployed in all varieties over the coming months!
