Land more bundles, faster.
Harmonic evaluates your bundle where the block is built. It lands sooner, stays private, and your full tip counts.
A bundle is all or nothing.
Searchers send transactions as a bundle: a group that executes together, in order, or not at all. It is the unit Harmonic builds around.
Many transactions, one unit.
A bundle is a group of transactions that execute together, in the order you set.
One reverts, the bundle is dropped.
If any transaction would fail, none of them land, and you pay nothing for the attempt.
So you can bid aggressively.
Chase the opportunity. A failed play costs you no SOL.
Lower latency, fewer ways to miss.
Harmonic builds and evaluates your bundle in one place. Jito runs a separate engine, delays flow to wait for bundles, then merges at the validator, where a bundle can still fail on a state conflict.
Your strategy stays yours.
Bundles go through a private channel to vetted builders, never the public mempool, so they can't be copied, front-run, or unbundled. Leader filtering is coming, letting you send bundles to specific validators only.
No 6% Jito tax. Your full tip counts.
On Harmonic a tip is an ordinary priority fee, not a transfer to a tip account with a cut taken out. The full amount reaches the validator and counts.
Same tip, more of it counting. Rank higher for the same bid, or pay less for the same spot.
