# Use Privacy Protocols Like Railgun

{% endhint %}

## 1. Never pay Railgun fees from a wallet that funded the shield

* The wallet that deposits into Railgun must never be used to pay withdrawal gas.
* Treat the funding wallet as permanently tainted once it touches the shield.
* Do not reuse it for anything related to the withdrawal.

Rule: Funding wallet ≠ fee payer ≠ receiver.

## 2. If you want to pay the fee yourself, use a decoupled, pre funded fee payer

* Prepare a fee payer wallet long before any Railgun interaction.
* Fund it from an unrelated source, different timing, different amounts.
* Let it sit idle for days or weeks before use.

This breaks timing correlation.

## 3. Avoid tight timing between deposit and withdrawal

* Do not withdraw shortly after depositing. Just sitting there in Railgun for a long time. It is very safe.
* Wait long enough to blend into the anonymity set.
* Time variance matters as much as amount variance.

Bad: deposit → withdraw within hours Better: deposit → wait days or longer → withdraw

## 4. Use common, non unique amounts

* Avoid precise or unusual values like 0.099248 ETH.
* Use rounded, common denominations that many users use.
* Unique amounts act as fingerprints.

## 5. Do not immediately forward withdrawn funds

* Never withdraw and instantly fund another wallet.
* Add delays, intermediate steps, or additional shielding.
* Immediate forwarding creates deterministic links.

## 6. Social media poses significant risks.

For goodness’ sake, do not post your transaction on X right after you make it. That is basically doxxing yourself. Using your own X account while your public addresses are already known is not wise. 🫠
