+## `zkUseFactoryDep`
+
+### Signature
+
+```solidity
+function zkUseFactoryDep(string calldata name) external pure;
+```
+
+### Description
+
+Enables marking a bytecode as a factory dependency for the next CREATE or CALL and cleared after.
+
+This cheatcode is useful when deploying contracts through factories, as it allows marking bytecode as a factory dependency and deploying contracts by passing their bytecode hash to the factory.
+
+### Examples
+
+```solidity
+contract Deployer {
+    // 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);
+}
+```
