+A quick and easy method for testing a running CDK stack, whether in validium or rollup mode, is by sending a zero-value transaction and examining the result.
+
+## Cast method
+
+In a terminal window, run the following command where the mnemonic is used just for testing and the address can be any valid account address. 
+
+```sh
+cast send --legacy --mnemonic 'code code code code code code code code code code code quality' --value 0 --gas-price 0 --rpc-url http://127.0.0.1:8123 0x0bb7AA0b4FdC2D2862c088424260e99ed6299148
+```
+
+You should see something like this as output:
+
+```sh
+blockHash               0x5d6d45f46e54c5d0890dd8a4ede989dc8042d7d3aeada375ea11d2e77c91a298
