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.

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.
Key features of Cloaked

- Standard mode (simple) and private ZK mode (zero-knowledge proofs)
- Native support for x402 pay-per-use payments
- Real-time multi-agent dashboard with one-click freeze
- USDC token support with per-token spending constraints
Use cases of Cloaked
- AI agents paying for APIs or services autonomously without wallet risk
- Enforcing budget caps on autonomous trading, data fetching, or content generation agents
- Privacy-preserving agent-to-agent payments using zero-knowledge proofs
- Safe delegation of spending to AI agents for decentralized application interactions
Frequently asked questions
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.
Which blockchains and technologies does Cloaked use?
Cloaked runs on Solana, uses Helius RPC, Anchor for the smart contract, Noir + Barretenberg + Sunspot for ZK proofs, and supports USDC tokens.
Can I freeze a Cloaked agent instantly?
Yes. The dashboard provides a one-click freeze that stops all spending from the agent immediately.
Is Cloaked available on mainnet?
The README provides program IDs on Devnet only. Full documentation is available at cloakedagent.com/docs.
