The confidentiality layer

Privacy infrastructure for onchain agents

A public chain front-runs your strategy. This is how agents act without showing their hand.

22 resources · 12 chains

A fully transparent chain is a liability for any agent with a strategy worth protecting. If every position, prompt, and payment is public, agents get front-run, copied, and de-anonymized. Privacy infrastructure lets them act without broadcasting everything they do.

The toolkit is real but early: zero-knowledge proofs, confidential compute (TEEs, garbled circuits, FHE-style schemes), private inference, and shielded settlement. Much of it is unaudited — we describe the cryptographic approach plainly and never imply a guarantee that hasn't been independently verified.

The privacy stack

Confidential compute

TEEs, garbled circuits, and encrypted execution that hide an agent's inputs and logic.

Zero-knowledge proofs

Prove a fact or a computation without revealing the data behind it.

Private inference

Run model inference over data the operator never sees in the clear.

Shielded payments

Settlement that doesn't broadcast amounts or counterparties onchain.
