# Supported Rollup Stacks

**Arbitrum Orbit**

Arbitrum Orbit is Arbitrum's technology that provides a permissionless path for launching your own customized Arbitrum Rollups.

The rollups created using Arbitrum Orbit are tightly coupled to Arbitrum’s L2 chains; Arbitrum One and Arbitrum Nova, allowing users to benefit directly from Etherium’s security.

**Benefits**

* **Faster Throughput:** Arbitrum's rollup design allows for quicker consensus and finalization of transactions within its off-chain environment achieving faster confirmation times.
* **Scalability:** Arbitrum’s rollup solution significantly increases the scalability of Ethereum via off-chain transactions processing, and batching them into Ethereum thereby reducing congestion on the mainnet.
* **Reduced Transaction Fees:** By batching transactions and processing them off-chain, Arbitrum significantly reduces transaction fees.
* **EVM Compatibility:** Arbitrum is designed to be fully compatible with the Ethereum Virtual Machine (EVM) and supports most Ethereum smart contracts and decentralized applications.
* **Customizable fee token:** Arbitrum Orbit chains can use any token users choose as the fee token.
* **Security:** Arbitrum technology powers the most secure L2s, by periodically submitting cryptographic proofs to the Ethereum mainnet.
