## First Thing First: Prepare a Railgun supported Wallet

Shielded balances are chain-specific. A shielded balance on Ethereum is distinct from shielded balances on PulseChain or other networks.

### RAILGUN → PulseChain

#### Step 1: Initiate an Intent to Receive WETH (PulseChain) in Liberty Swap

Within the Liberty Swap interface:

1. Connect your wallet
2. Select **Private Mode**.
3. Choose the supported private route (ETH → WETH).
4. Specify the amount to swap (subject to current private route limits).
5. Fill in the Destination Address.
6. Click \[**Swap**] then \[**Next**].
7. Copy LibertySwap’s given Railgun ZK address.

#### Step 2: Send ETH to Liberty Swap

 Within the RAILGUN-powered wallet:

1. Ensure you are operating on the **ZK (shielded) side**.
2. Initiate a transfer from your ZK address to Liberty Swap’s ZK address by pasting the Liberty Swap’s given ZK address into the Recipient box.
3. Enter the same amount as filled in the Liberty Swap interface in the previous step.

#### Step 3: Include the Private Memo

1. Copy the memo provided by LibertySwap.
2. Paste it into the **optional private memo field** in your RAILGUN wallet.
3. Generate the ZK proof.
4. Submit the transaction in your wallet.

This memo enables Liberty Swap’s relay to correctly attribute and settle the incoming shielded transfer.
