Connecting Wallets

HideMyTx uses two wallet types. Private Swaps and Normal Swaps do not require a connected wallet to get a quote, but Private Send (Solana) requires Phantom and Shielded Send (EVM) requires any EVM browser wallet.

Feature	Wallet required
Private Swaps	None (optional for source chain)
Normal Swaps	None
Private Send (Solana)	Phantom
Shielded Send (EVM)	Any EVM browser wallet (MetaMask, Rabby, etc.)

Solana (Phantom)
EVM (MetaMask / any EVM wallet)

Connecting Phantom

Install Phantom

Download the Phantom browser extension and create or import a wallet. HideMyTx connects to Phantom via the standard Solana wallet adapter.

Click Connect in the Private Send panel

Open the Private Send workstation and click Connect Wallet. Phantom will prompt you to approve the connection.

Sign the encryption key derivation message

After connecting, HideMyTx asks you to sign a short message:

Privacy Money account sign in

This signature is used to derive your PrivacyCash encryption key — it never leaves your browser and is not a transaction. Your private UTXO balance is only readable with this key.

The signature is cached in localStorage so you only sign once per wallet address per browser. Subsequent sessions load the cached signature automatically without prompting you again.

What happens after signing

HideMyTx derives your PrivacyCash encryption key from your wallet signature. This key is used to read and spend your shielded UTXO balance. The key is deterministic — signing again with the same wallet always produces the same key, so your shielded funds are always recoverable.

Connecting an EVM wallet

Any EVM-compatible browser wallet works — MetaMask, Rabby, Frame, Coinbase Wallet, and others.

Install an EVM wallet extension

Install MetaMask or any EVM browser. Make sure your wallet is unlocked before connecting.

Click Connect in the Shielded Send panel

Open the Shielded Send workstation and click Connect Wallet. Your wallet will prompt you to approve the connection and switch to the selected network (Ethereum, Arbitrum, Polygon, or BNB Chain).

Sign the two RAILGUN derivation messages

HideMyTx requests two signatures to bootstrap your RAILGUN private wallet:

Wallet seed signature — signs the message HideMyTx RAILGUN wallet to derive your RAILGUN mnemonic and encryption key
Shield key signature — signs a RAILGUN-generated message to derive your shield private key

Both signatures are off-chain (no gas required) and deterministic. Your RAILGUN address and private balances are always recoverable from these two signatures.

Wait for the RAILGUN engine to bootstrap

On first connect, the RAILGUN engine loads. This typically completes in a few seconds.The engine also runs a short scan to find any existing shield history for your address. Subsequent connects reuse the stored wallet state and load much faster.

Supported networks

Network	Chain ID
Ethereum	1
Arbitrum	42161
Polygon	137
BNB Chain	56

HideMyTx will prompt your wallet to switch to the correct network automatically when you select a chain in the Shielded Send panel.

If the automatic network switch fails (some wallet extensions block this), switch networks manually in your wallet and reload the Shielded Send panel.

Disconnecting

HideMyTx does not store private keys or mnemonics. To disconnect, use the disconnect option in your wallet extension.
