Harmonic
Harmonic is a Solana block engine with private, revert-protected bundle submission for atomic strategies.
About this tool
Harmonic Bundles lets approved searchers submit multi-transaction bundles to a Solana block builder through a gRPC interface compatible with Jito searcher flows. Submitted bundles are evaluated against live state where blocks are built and are intended to land together or not at all.
The service provides bundle privacy and drops an entire bundle when one of its transactions reverts. It is aimed at Solana searchers running atomic arbitrage, liquidations, JIT liquidity, and other structured MEV strategies that require coordinated execution.
