Swansea City and Ipswich Town were also interested in a move after Trusty’s exploits on loan at St Andrew’s last season.
"I am more than excited,” he told the club’s official website.
“The opportunity to be here at this historic club, and an opportunity to play in the Premier League and show my ability, it is everything I could have ever dreamed of growing up as a kid.
"In Pennsylvania, this was a dream - almost an impossible dream but I believed in myself and the opportunity has come around, it is everything that I dreamed for.
"It is crazy how quick things happen in football. I have just come back from a US tour with Arsenal and a couple of days later I am sitting here doing this interview.
"Things did happen very quick, but that’s how football works. I was really looking for an opportunity so as soon as it came about, things and details were ironed out. I am here, I wasn’t wasting any time.
"Everything is coming to fruition for me. I am in the right place at the right time and in the right mindset. Everything has come together how I dreamed it."
After spending big on Kai Havertz, Jurrien Timber and Declan Rice, the Gunners have shifted their focus to selling players.
Former club record signing Nicolas Pepe could follow Trusty through the exit door amid interest from Turkish side Besiktas.
The Istanbul giants are keen on a move for the Ivory Coast international, who has just one year left on his contract at Arsenal.
