+         contract.
+
+**`Throws`**

+
+The chain-specific identifier of the contract that will be
+         used as the actual L1 depositor embedded in the deposit script.
+         In this case, the depositor must be the L1BitcoinDepositor contract
+         corresponding to the given L2 chain the deposit is targeting.
+         This is because the L1BitcoinDepositor contract reveals the deposit to
+         the Bridge contract (on L1) and transfers minted TBTC token to the
+         target L2 chain once the deposit is processed.
