Threat Model
Cloak is designed to protect against specific threats inherent to public blockchains:- Wallet Linkability: Preventing observers from easily linking a swap to your main wallet.
- Strategy Inference: Making it difficult to guess your overall position or strategy based on a single transaction.
- MEV/Sandwich Attacks: Reducing the risk of predatory trading bots by using private executors.
What we DO protect against
- Basic Linkage: Your wallet never signs the swap transaction.
- Clustering: Repeated trades from the same wallet are harder to correlate.
- Pattern Recognition: Chunking and randomization make large orders look like unrelated market noise.
What we do NOT protect against
- Nation-State Adversaries: Advanced traffic analysis (IP/timing correlation) is out of scope.
- Fund Flows: If you withdraw from a KYC’d exchange directly to a fresh wallet and then use Cloak, the flow of funds is still traceable on-chain.
Safety Principles
- No Loss of Funds: In the event of a system failure, your funds should always be recoverable.
- Non-Custodial: We do not hold your private keys or pool your funds (except in the specific case of the Escrow for Stealth Sells).
