The confidentiality layer
Privacy infrastructure for onchain agents
A public chain front-runs your strategy. This is how agents act without showing their hand.
8 resources · 6 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.

What Are Onchain Agents?
Onchain agents are autonomous AI agents that can interact with blockchain systems, holding wallets, signing transactions, reading chain data, and executing workflows across protocols without constant human input.
How Agents Use Wallets
Agent wallets are key-management systems that let an AI agent sign transactions programmatically, ideally with policies, spend limits, and approval flows that constrain what the agent can do.
