Shielding

Move tokens to any 0zk address

Please note, as of 6 November 2023, new shields have an Unshield-Only Standby Period of 1 hour. During this period, the only available action will be to unshield back to the original shielding address. This is due to the Private Proof of Innocence system.

Shielding transfers tokens from a public 0x address to a private 0zk address. When shielding, the 0zk address is completely private and never appears on the blockchain.

Once in a 0zk address, your funds are completely sealed from public view and no one can see what you do or what you hold. To read more about RAILGUN privacy, check out this article.

From a 0zk address, users can send, swap, and interact with DeFi privately.

For an alternative to Shielding through Railway Wallet, you can send funds to any 0zk address with https://tokenshielder.com.

Further Info

All RAILGUN fees can be paid with wrapped base network tokens or stablecoins, so you do not need to keep a private balance of ETH, BNB or MATIC for transactions from your 0zk address.

If this is your first time using Railway Wallet, it's a good idea to Unshield some of the base network token (ETH/BNB/MATIC) to a fresh 0x address to assist with Self-Broadcasting as a backup to the Broadcaster network.
