This is an optimistic rollup built on Cosmos (using the Sei blockchain) that uses Solana’s Sealevel runtime as its Virtual Machine.
The Nitro team aims to create a gateway between the Solana and Cosmos ecosystems by capitalizing on Cosmos’ interoperability and Solana’s high throughput.
Sei’s ecosystem allows for Nitro’s Layer 2 infrastructure to become a standard for other protocols looking to use the SVM.
