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.) |
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
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 |
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.
