+## `zkUseFactoryDep`
+
+### Signature
+
+```solidity
+function zkUseFactoryDep(string calldata name) external pure;
+```
+
+### Description
+
+Marks a given contract as a factory dependency only for the next CREATE or CALL, unmarking it afterwards, similar to [`prank`](../../cheatcodes/prank.md).
+
+This cheatcode is useful when deploying contracts through factories that do not directly depend on a given contract, as it allows explicitly marking this type of contract as a factory dependency, enabling the factory to deploy the contract.
+More information on factory dependencies can be found in the [official ZKsync docs](https://docs.zksync.io/build/developer-reference/ethereum-differences/contract-deployment#note-on-factory_deps).
+
+### Examples
+
+```solidity
+contract Deployer {
+    // Factory does not directly depend on TwoUserMultisig, so we need to mark it explicitly
+    // as a factory dependency to allow deployment through the factory
+    // Deploy the factory
+    Factory factory = new Factory(multisigBytecodeHash);
+
+    // Mark the bytecode as a factory dependency
+    vmExt.zkUseFactoryDep("TwoUserMultisig");
+
+    // Deploy the account using the factory
+    factory.deployAccount(multisigBytecodeHash);
+}
+```
