Self-Broadcasting

Users can sign transactions using any 0x wallet, avoiding the use of a Broadcaster. Self-Signing may sometimes be preferable to save on Broadcaster fees. A broadcaster is any 0x address that pays the gas on behalf of a 0zk address. Read more about RAILGUN Broadcasters here.
First we need to create a 2nd, fresh new wallet in Railway Wallet. This wallet should have a clean history on Etherscan or other block explorers.
Next we need to Unshield ETH/MATIC/BNB into this new wallet. Click Unshield as ETH/BNB/MATIC to ensure the self-broadcast wallet can pay for gas. This will require a existing Broadcaster, this way the origin of these funds will be the RAILGUN smart contract, rather than any address linked to you.
Your 0zk address supports WETH. This can be unshielded to the self-broadcaster wallet you just created. If you do not have any WETH, you can perform a private swap to obtain it.
When performing a transaction on railway you may choose between "public broadcaster" and "self-broadcast".
At your next "self-broadcast" transaction, click the "Signer" field. Select the newly created and seeded wallet.
