+## Override state values
+
+You can override an account with temporary state values before making the call. This allows you to
+make temporary state changes without affecting the actual blockchain state.
+
+The following example estimates the cost for transferring an ERC-20 token for an account which does not
+have the required assets onchain.
+
+The example sets a custom ETH balance for the sender (to cover gas costs) and modifies the account's
+balance within the ERC-20 contract's storage for the duration of the call.
