— Secondary surfaces

Everything else we built.

Zerith's primary product is encrypted block sales for token foundations. These are the other primitives we built on the same FHE stack — auction variants, payroll, OTC, observability. Every page works; all share the same threshold network and the same privacy guarantees.

— A note on scope

We built breadth to prove FHE is generalizable across the whole on-chain finance stack — not just one feature. For production, we lead with block sales because that's where the buyer pain is most acute and the unit economics work today. The rest is here, it works, and it becomes load-bearing as the product expands.
