The client seed wil be converted to a 32 byte hex (shown on the left).

The client verifies deck and server seed on each stand or bust before showing the result, so you can be sure to always see the correct data. Furthermore, the contract verifies the result when you claim your win.
Additionally, you can click on the "verify on contract"-button above. This will reconstruct the shuffled deck using server and client seed and then send deck and seed to the contract for verification.
