# The Shadow Bridge

Moving assets from Ethereum (Public) to FOGEVM (Private) requires a sophisticated bridging protocol designed to break the link between sender and receiver.

#### The Lock-and-Mint Protocol

1. Deposit: A user deposits ETH into the FOGEVM Bridge Contract on Ethereum Mainnet.
2. Anonymization Event: The Bridge Contract generates a "Deposit Note".
3. Relay: The user waits for a random delay to submit this Deposit Note to the FOGEVM L2.
4. Mint: The FOGEVM L2 verifies the note has not been spent and mints the equivalent pETH (Private ETH) to a fresh address.

* Result: There is no on-chain link between the L1 deposit address and the L2 destination address. The graph is severed.
