The 21-year-old from Edinburgh followed up gold in the 400 metres individual medley and 4x200m freestyle silver with another second-place finish in the 200m IM.
After celebrating his Commonwealth Games victory by bellowing out 'For Freedom', the patriotic Scot had the home crowd roaring with approval on Tuesday evening as he strode out to the Tollcross pool wearing a kilt.
And he hopes to cement his growing popularity by qualifying for the Rio Olympics in two years' time.
He said: "I just love the support I've been getting. There are so many people I have never met before but they are still supporting me and it's such a great feeling.
"My dream is to one day be famous so I hope this is the start of it.
"Every day I wake up and I've got hundreds and hundreds of messages. People look up to me and say I inspire them. It really does warm my heart.
"Swimming has become a much more popular sport and it's great for the younger generation of swimmers to see people like Michael Jamieson and myself on TV.
"Hopefully one day I can become a superstar in the sporting world and inspire people to get involved in the sport."
Wallace is ranked just 28th in the world over 200m but his performance in winning the 400m propelled him up to joint fourth over that distance, and he believes such form can make him a medal prospect for the 2016 Olympics.
He said: "After this week, I'm definitely in contention for Rio. Swimming in Great Britian is so strong right now. Once you make the team the expectations are a lot higher.
"You have got to get on the podium and make finals. But we are all capable of that and the next couple of years for British swimming are going to be pretty special."
After his tartan tribute to the home fans, Wallace - who was joined in donning the kilt by his watching team-mates - had to battle to put himself in with a shout of a medal in the shorter medley race.
He found himself in last place midway through the final, with South Africa's Chad le Clos so dominant that he was a full second ahead after the first butterfly leg.
But Wallace fought back magnificently thanks to a sensational breaststroke length to go into the last 50m in real contention and he beat Le Clos to silver, finishing behind Australian Daniel Tranter who set a Games record of one minute and 57.83 seconds.
"It feels phenomenal to have won another medal," Wallace said. "After the week I have had, that silver just tops things off.
"I didn't expect to do that well last week, but after what happened I knew I had it in me to get a medal, and I'm just so happy I did that today.
"Wearing the kilt was a bit of a team decision. With us being the home nation, we wanted to show our pride off. It was a little special thing for the fans. I hope they enjoyed it.
"We said, 'Let's step our game up on the last night'.
"Performance-wise I think I did that and the emotions I had when I was walking out were amazing. The crowd were amazing, they stepped their game up too. It's something I will never forget.
"This is the best competition I've been to ever in my life. I don't think anything will ever top this."
