 3. The STB `L1Escrow` locks the USDC and passes a message to the unified messenger containing the user’s address and amount of USDC being bridged.  
 4. The `Messenger` contract validates the message and then sends it to the STB `L2Escrow`.

 - The STB flow involves locking tokens in the L1Escrow contract, which is followed by the minting of USDC.e on L2.
 - On the other hand, if the tokens are deposited directly into the LxLy bridge contract, it results in the minting of LxLy USDC on L2.
 
-The `L2TokenConverter` facilitates conversion between **USDC.e** and **LxLy USDC**. The way it works is by locking (Deposit function) either of the tokens in the converter contract, and then sending (Withdraw function) the equivalent amount of the other token to the user's wallet.
