Harmonic is a configurable block-building infrastructure for the Solana blockchain. It lets validators choose their own block-building strategy and builder, aiming to capture more upside and attract stake, while also serving searchers who want to send bundles with lower latency and revert protection.

Description
Harmonic provides configurable block building infrastructure for Solana validators. Its system routes transactions from a Remote TPU through connected block builders, using sticky bindings between validators and builders with automatic failover to ensure uptime. The platform is built around a principle of validator autonomy, letting operators pick their own scheduling strategy and builder rather than prescribing a single path. Harmonic serves two main client types: validators, who can run Harmonic to control how their blocks are built, keep fees and tips, and avoid missing leader slots; and searchers, who can send bundles with no protocol cut on tips, lower latency, and protection against reverts.Grant Funding
