Blockchain infrastructure developer Fermah.xyz builds tools for autonomous protocols and ZK proof generation

Fermah.xyz – GoDaddy customer – (United States)

TL;DR:

• ​Fermah.xyz is the online home of Fermah, which calls itself “Protocol Agency Infrastructure.” Its products include Kernel, an engine that lets protocols take action on their own, and Froben, a marketplace for ZK proofs.
• The company raised a $5.2M seed round co-led by the a16z CSX fund and Lemniscap in September 2024.
• According to Fermah.xyz, Froben is live on mainnet and counts ZKSync Era and Abstract Chain among its paying customers.

Fermah.xyz Overview

• What: Fermah builds products for autonomous protocols. With Kernel, a protocol can act on its own once a condition is proven, built into the chain as a core feature: “if this verifiable thing is true, do that action.” Froben is a marketplace that connects projects needing ZK proofs with providers who generate them.
• How: AI agents assemble Kernel workflows, but deterministic code runs them, so the same inputs always produce the same result, and no AI is involved. Fermah says each workflow is “executed in isolated environments built for untrusted code,” and Kernel records the outcome on the blockchain, backed by cryptographic proof. On Froben, a “Matchmaker” matches proof requests with GPU and CPU machines that can generate them.
• Why: According to Fermah.xyz, “every smart contract ever written is still purely reactive.”
  The company pitches Kernel as the fix and as the meeting point for AI agents and autonomous protocols, saying, “Kernel is to protocols what TCP/IP was to machines.”
• Who: Fermah was founded by Dr. Vanishree Rao, who holds a PhD in cryptography from UCLA and has been building ZK for 15+ years.
• Where: Fermah is headquartered in New York City, according to its LinkedIn profile.
