Alchemy Rollups currently supports **Arbitrum Nitro (Orbit)** as its rollup framework.

## Arbitrum Nitro (Orbit)

* **Overview:** A robust optimistic rollup with enhancements for performance.

* **Key Benefits:**

  * Ultra-low transaction fees with options for even lower costs through alternative data availability models.
  * Fast block times and efficient batching.
  * Full EVM compatibility, with optional support for additional smart contract languages.
  * Interoperability with other chains in the Arbitrum ecosystem.
  * [**Stylus**](https://medium.com/offchainlabs/hello-stylus-6b18fecc3a22), which will allow you to write smart contracts in a more performant VM with Rust, C++, or other languages that can compile to WASM. These contracts can interoperate synchronously with the EVM.

* **Use Case:** Best suited for high-throughput applications with diverse transaction requirements.
