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.
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.
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.
| Situation | Use |
|---|---|
| Default / automated pipeline | Server (REST API) |
| No Docker server available | CLI (shadowcli.mjs) |
| Scripted proving only | start.sh --prove FILE (see server reference) |
| Error | Fix |
|---|---|
insufficient balance: X < Y | Fund target on L1, wait for checkpoint, retry |
nullifier already consumed | Note already claimed — skip, check others |
Please install docker first | Start Docker daemon |
RPC chainId mismatch | Use L1 RPC matching deposit's chainId |
DEPOSIT schema validation failed | See deposit schema |
| Server not responding | Re-run start.sh |
| Step | Tool | Purpose |
|---|---|---|
| Before deposit | get_balance | Verify source address has enough ETH on L1 |
| After funding | get_transaction_info | Confirm L1 funding tx is confirmed |
| During prove | get_bridge_message_status | Track cross-chain relay status |
| Before new deposit | get_pending_messages | Check for stuck prior deposits |
| Before claim | get_gas_price | Estimate L2 claim tx cost |
taiko bridge status <TX_HASH> --json # check bridge relay for L1 funding tx
taiko bridge history <ADDRESS> --json # list all bridge deposits for an address
Use TaskCreate / TaskUpdate to persist deposit_id across session interruptions:
deposit_id and targetAddress in descriptionTaskList → find in_progress shadow deposits → extract deposit_idnpx claudepluginhub taikoxyz/taiko-ai --plugin taiko-x402Enables confidential ERC20 payments on Starknet using the Tongo protocol with encrypted balances, ZK proofs, and optional auditor compliance.
