# What is Nezo Sydra?

### Sydra (L2)

[**Nezo Sydra**](/nezohub/overview/what-is-nezo-sydra.md) is a Layer 2 (L2) scaling solution that leverages [zero-knowledge proofs](/nezohub/overview/research/zero-knowledge-proofs.md) to enhance Ethereum's scalability while preserving full [EVM compatibility](/nezohub/overview/research/zk-evm.md). This enables developers to seamlessly migrate existing Ethereum applications and benefit from significantly reduced transaction fees and faster confirmation times. By bundling transactions into batches verified by cryptographic proofs, Nezo Sydra ensures the highest level of security and performance.<br>
