Nethermind
A C#/.NET Ethereum execution client — full-featured, MEV-friendly, with strong performance on archive sync and a large enterprise install base.
Nethermind is one of the four main Ethereum execution clients (alongside Geth, Erigon, and Besu). Written in C# on .NET, it targets enterprise and validator operators that want non-Geth alternatives for client-diversity reasons.
It supports both full and archive sync modes, has rich JSON-RPC, and ships MEV-Boost integration out of the box. The Nethermind-developed Voluntary Exit Manager (VEM) and Sedge deployment tool are widely used by professional validator operators.
