Our cofounder and CTO Jakob Povsic joined 60 industry leaders urging the Senate to pass the Clarity Act with developer protections and the BRCA intact. Clear rules let infrastructure builders keep advancing decentralized protocols in the US.

1/ Announcing Harmonic Preconfs, now in private pilot.
A gRPC stream of Solana transactions emitted the moment the Harmonic builder identifies them for inclusion, before they enter shred form.
Every public early-data product on Solana today sits downstream of shred generation. Preconfs sits upstream of it.
For the slots Harmonic builds, there is no earlier read in existence.

7 / Harmonic builds ~20% of Solana slots today.
Every additional Harmonic validator expands the slot coverage Preconfs runs on. More Harmonic slots, more signal.

Super happy to see it paying off

i expect harmonic validators to do very well once 100m cus ptoken goes live, assuming there's enough traffic
a good chunk of the alpha in harmonic builders comes from high performance infra, vs what folks traditionally view as mev; searchers love to spam with a passion.
we're on a generational cooking run rn on this front and about to plate it up. dm @harmonic_gg to get connected

1/ PropAMMs and the Next Chapter of Permissionless Market Structure
For years, onchain trading won on access, lost on execution. Some feel better performance requires moving backwards to centralized systems
PropAMMs on @solana are proving permissionless can outcompete centralized
