It’s time to wash hands again, but this time with the blessing. It’s customary not to speak at all between washing your hands and saying the blessings over the matzo:

Baruch Atah Adonai, Eloheinu Melech ha-olam, asher kid’shanu b’mitzvotav v’tzivanu al n’tilat yadayim.

We praise God, Spirit of Everything, who commands us to wash our hands.
