About Cloaked

Give AI agents spending power without giving them your wallet keys. Cloaked creates on-chain spending accounts with enforced constraints that agents cannot bypass - even if jailbroken or compromised.

Overview

What is Cloaked?

Cloaked is a trustless spending accounts system for AI agents on Solana. It enforces spending constraints on-chain that an agent cannot bypass, even if jailbroken or compromised.

How to use Cloaked?

Add the Cloaked MCP server to your client configuration with npx cloaked-mcp and set the CLOAKED_AGENT_KEY environment variable. The agent can then call cloak_pay to spend SOL or USDC within the preset limits. Developers can also use the @cloakedagent/sdk npm package to create and spend from a Cloaked agent programmatically.

FAQ from Cloaked

How does Cloaked enforce spending limits?

Limits are enforced on-chain by a Solana Anchor program. The agent’s delegate key can only spend up to the constraints set by the owner, and even a jailbroken agent cannot exceed them.

What is the difference between standard and private mode?

In standard mode the owner’s wallet is linked on-chain to the agent. In private mode, zero-knowledge proofs hide this link, and the agent can be funded anonymously via Privacy Cash.
