Stealth addresses provide strong privacy by default. But certain usage patterns can degrade that privacy. This guide explains what to avoid and how the Wraith agent helps.

​
Privacy Scoring

The Wraith agent includes a privacy check tool that scores your stealth address activity: 
import { Wraith, Chain } from "@wraith-protocol/sdk";

const wraith = new Wraith({ apiKey: "wraith_..." });
const agent = await wraith.createAgent({
  name: "alice",
  chain: Chain.Horizen,
  wallet: "0x...",
  signature: "0x...",
});

const res = await agent.chat("run a privacy check");
// Privacy Score: 85/100
// Issues:
// - (medium) 7 unspent stealth addresses
// - (high) All recent payments are the same amount
// Best Practices:
// - Use a fresh destination for each withdrawal
// - Space withdrawals at least 1 hour apart

​
Scoring Algorithm

The privacy check starts at 100 points and deducts for observed risks:
ConditionDeductionSeverity
More than 5 unspent stealth addresses-10Medium
All payment amounts identical-15High
Consecutive payments less than 60 seconds apart-20High
Never withdrawn any payments-5Info
Connected wallet is the agent address-5Info

​
What to Avoid

​
1. Withdrawing to the Same Address

Bad: Withdraw all stealth addresses to one known wallet. 
Stealth Address 1 (0.1 ETH) -> 0xMyMainWallet
Stealth Address 2 (0.2 ETH) -> 0xMyMainWallet
Stealth Address 3 (0.5 ETH) -> 0xMyMainWallet

Observer: "These three stealth addresses all belong to the same person"
Good: Use a different destination for each withdrawal. 
Stealth Address 1 -> 0xFresh1
Stealth Address 2 -> 0xFresh2
Stealth Address 3 -> 0xFresh3

Observer: "Three unrelated withdrawals to three unrelated addresses"
The Wraith agent warns you automatically: 
await agent.chat("withdraw all to 0xMyMainWallet");
// "Privacy concern — withdrawing all stealth addresses to a single
//  known wallet links every payment to your identity."

​
2. Timing Correlation

Bad: Withdraw multiple stealth addresses within seconds. 
14:00:00 — Withdraw from 0xStealth1
14:00:02 — Withdraw from 0xStealth2
14:00:04 — Withdraw from 0xStealth3
Good: Space withdrawals hours or days apart.

​
3. Amount Fingerprinting

Bad: Always send the exact same amount. 
Send 0.100000 ETH to Stealth1
Send 0.100000 ETH to Stealth2
Send 0.100000 ETH to Stealth3
Good: Vary amounts slightly. 
Send 0.098372 ETH to Stealth1
Send 0.102841 ETH to Stealth2
Send 0.099127 ETH to Stealth3

​
4. Address Reuse

Stealth addresses are one-time by design. The Wraith protocol enforces this — each payment generates a fresh address automatically. If you’re building custom integrations with the EVM crypto primitives, call generateStealthAddress() for each payment.

​
5. Linking On-Chain Identity

Bad: Withdraw from a stealth address directly to a wallet tied to your ENS, .wraith name, or known identity. Good: Use an intermediate address with no on-chain identity.

​
How the Agent Helps

The Wraith AI agent is privacy-paranoid by design. It will:
  • Warn before risky actions — explains the risk before executing
  • Suggest alternatives — recommends fresh addresses, spacing, and varied amounts
  • Run privacy checks — analyzes your activity and flags patterns
  • Remember context — factors past risky moves into future advice
  • Respect your decision — executes after warning if you insist

​
Example: Agent Warning

await agent.chat("withdraw all to 0xMyMainWallet");
Response: 
Privacy concern — withdrawing all stealth addresses to a single
known wallet links every payment to your identity. Observers can
trace all incoming stealth payments back to you.

Recommendations:
- Use a fresh address for each withdrawal
- Space withdrawals hours apart
- Withdraw to different destinations

Proceed anyway?

​
Example: Proactive Detection

await agent.chat("send 0.1 ETH to bob.wraith");
// ... later ...
await agent.chat("send 0.1 ETH to carol.wraith");
// ... later ...
await agent.chat("send 0.1 ETH to dave.wraith");
Response on the third send: 
Payment sent. Note: your last 3 payments were all exactly 0.1 ETH.
Identical amounts create a fingerprint. Consider varying the amount.

Best Practices Summary

PracticeWhy
Use a fresh destination for each withdrawalPrevents linking stealth addresses to one identity
Space withdrawals at least 1 hour apartDefeats timing correlation analysis
Never withdraw to your connected walletKeeps your identity separate from stealth activity
Vary payment amounts slightlyPrevents amount-based fingerprinting
Use different times of dayAvoids timezone-based profiling
Consolidate stealth addresses periodicallyReduces on-chain footprint
