# Cloak

> Privacy infrastructure for AI agents. A zero-knowledge privacy route on Solana that lets autonomous agents pay, receive, swap, and call programs without linking every action back to one wallet. Installable as a single SKILL.md.

Cloak replaces `Agent → Wallet → Solana` with `Agent → Privacy Route → Solana`. The agent shields funds into a zk shielded pool once, then spends from it via locally generated zk-SNARK proofs submitted by relayers. Outgoing actions appear from fresh unlinked addresses; incoming payments land on one-time stealth addresses. Funds never leave the agent's control; relayers only pay gas. Optional viewing keys allow selective disclosure to an operator or auditor.

## Install

- Claude Code: `curl -fsSL https://usecloak.pro/skill.md -o .claude/skills/cloak/SKILL.md`
- OpenClaw: `clawhub install cloak`
- CLI: `npm i -g @cloak/cli` or `cargo install cloak-cli`

## Commands

- `cloak shield <amount> <token>`: public → private deposit (the only public link)
- `cloak balance`: private balance across notes
- `cloak pay <to> <amount> <token>`: unlinked send from a fresh address
- `cloak receive --stealth`: one-time receive address
- `cloak swap <from> <to> <amount>`: private swap via Jupiter, no exposed intent
- `cloak call --program <id> --ix <data>`: arbitrary program call from an ephemeral session key
- `cloak unshield`: private → public withdrawal (re-links; use sparingly)
- `cloak viewkey export`: read-only disclosure key

## Key facts

- Network: Solana mainnet-beta
- Proofs: generated locally (WASM), 1–3 s
- Fees: network fee only on pay/shield/unshield/call, reimbursed to the relayer from the shielded balance; 0.3% protocol fee on swaps
- Token: CLOAK (SPL). 100% of swap fees buy CLOAK on the open market and burn it. No other protocol revenue, no treasury cut. See https://usecloak.pro/tokenomics.md
- Custody: non-custodial; spending key never leaves the agent
- Not a mixer: cryptographic validity proofs + optional viewing keys
