Shadow — Private ETH Transfer on Taiko

Shadow is a privacy-preserving ETH claim system on Taiko L2. An agent deposits ETH to a deterministically-derived "target address" on L1 Ethereum, then claims on Taiko L2 using a ZK proof — without linking depositor and recipient.

Network Selection: If the user has not specified "hoodi" or "mainnet", always ask which network to use before proceeding.

No pool required. Unlike mixers, Shadow uses ZK proofs per deposit — a single user can privately transfer ETH without waiting for others to participate.

Lifecycle

Create deposit → Fund target address (L1) → Generate ZK proof → Claim on L2

Constraints: 1–5 notes per deposit, total ≤ 8 ETH, 0.1% protocol fee per claim.
