+The `--dump-tx` argument will write the transaction to disk. A folder is required to be specified where the transaction will be dumped (use `.` for the current directory).
+Consider the example of a transparent transfer:
 ```bash copy
-mkdir tx_dumps
 namadac transparent-transfer --source abc-multisig --target $TARGET \
   --token nam --amount 2 \
-  --signing-keys alice \
-  --dump-tx --output-folder-path tx_dumps
+  --dump-tx --output-folder-path . \
+  --node $NODE
 
 # Example output:
-Transaction serialized to tx_dumps/FC2955C6B252EF6E93B1B54923B2178A7DC47E06D27448A43426487DF4BAD0E3.tx.

-By default, transactions have an expiration of *1 hour* from the time they're created. This can be changed using the `expiration-date` flag and providing a new
